This creates a poor user experience as most users can see buttons, making the link redundant for the majority. Changes: - Reorder email content to show button first, then link - Update all translations (de/en/pt) to reflect new order - Add "or" prefix to link text to indicate it's a fallback option Affected emails: - Login email (auth.service.ts) - KYC reminder, failed, and missing data emails (kyc-notification.service.ts) - Account merge request email (account-merge.service.ts) This improves UX by prioritizing the primary action (button) and making the plain-text link available only for clients that don't support buttons. --- src/shared/i18n/de/mail.json | 8 +++---- src/shared/i18n/en/mail.json | 8 +++---- src/shared/i18n/es/mail.json | 8 +++---- src/shared/i18n/fr/mail.json | 8 +++---- src/shared/i18n/it/mail.json | 8 +++---- src/shared/i18n/pt/mail.json | 8 +++---- .../kyc/services/kyc-notification.service.ts | 24 +++++++++---------- .../account-merge/account-merge.service.ts | 8 +++---- .../generic/user/models/auth/auth.service.ts | 8 +++---- 9 files changed, 44 insertions(+), 44 deletions(-) diff --git a/src/shared/i18n/de/mail.json b/src/shared/i18n/de/mail.json index 1f06c6410b..180c054df2 100644 --- a/src/shared/i18n/de/mail.json +++ b/src/shared/i18n/de/mail.json @@ -7,13 +7,13 @@ "welcome": "Hi {name}", "team_questions": "Bei Fragen zögere bitte nicht, uns anzusprechen.", "personal_closing": "Freundliche Grüsse,

Also added validation to throw clear errors if address or deposit is missing. --- .../core/sell-crypto/route/sell.controller.ts | 2 +- src/subdomains/core/sell-crypto/route/sell.service.ts | 11 +++++++---- 2 files changed, 8 insertions(+), 5 deletions(-) diff --git a/src/subdomains/core/sell-crypto/route/sell.controller.ts b/src/subdomains/core/sell-crypto/route/sell.controller.ts index 5eae1d23c5..386d6eeb83 100644 --- a/src/subdomains/core/sell-crypto/route/sell.controller.ts +++ b/src/subdomains/core/sell-crypto/route/sell.controller.ts @@ -170,7 +170,7 @@ export class SellController { if (!request.isValid) throw new BadRequestException('Transaction request is not valid'); if (request.isComplete) throw new ConflictException('Transaction request is already confirmed'); - const route = await this.sellService.getById(request.routeId); + const route = await this.sellService.getById(request.routeId, { relations: { deposit: true } }); if (!route) throw new NotFoundException('Sell route not found'); return this.sellService.createDepositTx(request, route); diff --git a/src/subdomains/core/sell-crypto/route/sell.service.ts b/src/subdomains/core/sell-crypto/route/sell.service.ts index 3122da3765..4c43494f77 100644 --- a/src/subdomains/core/sell-crypto/route/sell.service.ts +++ b/src/subdomains/core/sell-crypto/route/sell.service.ts @@ -285,18 +285,21 @@ export class SellService { } } - async createDepositTx(request: TransactionRequest, route: Sell): Promise { + async createDepositTx(request: TransactionRequest, route: Sell, userAddress?: string): Promise { const asset = await this.assetService.getAssetById(request.sourceId); if (!asset) throw new BadRequestException('Asset not found'); const client = this.blockchainRegistryService.getEvmClient(asset.blockchain); if (!client) throw new BadRequestException(`Unsupported blockchain`); - const userAddress = request.user.address; + const fromAddress = userAddress ??

Security layers: - Role-based access (DEBUG/ADMIN/SUPER_ADMIN only) - SQL parsing with node-sql-parser (AST validation) - Only single SELECT statements allowed - Blocked: UNION/INTERSECT/EXCEPT, SELECT INTO, FOR XML/JSON - Blocked: OPENROWSET, OPENQUERY, OPENDATASOURCE (external connections) - Pre-execution column checking (blocks alias bypass) - Input validation with MaxLength(10000) - Post-execution PII column masking (defense in depth) - Full audit trail with user identification Blocked columns: mail, email, firstname, surname, iban, ip, apiKey, etc. * fix(gs): resolve eslint warnings in debug endpoint - Remove unused catch variable (use bare catch) - Remove unnecessary eslint-disable directive * [NOTASK] add more blockedCols * fix(gs): move restricted columns from ADMIN to DEBUG blocking - Remove organization.name, bank_tx.name, kyc_step.result from RestrictedColumns - Add 'name' and 'result' to DebugBlockedColumns - ADMIN can now see these columns on /gs/db - DEBUG role has these blocked on /gs/debug * fix(gs): implement table-specific column blocking for debug endpoint (#2782) * fix(gs): implement table-specific column blocking for debug endpoint Replace generic DebugBlockedColumns list with table-specific blocking: - TableBlockedColumns: Record maps each table to its blocked columns - Pre-execution: Check columns against their specific tables - Post-execution for SELECT *: Mask columns from all query tables Examples: - SELECT name FROM asset → ALLOWED (asset has no blocked columns) - SELECT name FROM bank_tx → BLOCKED (bank_tx.name contains personal data) - SELECT * FROM bank_tx → name masked post-execution Tables with blocked columns: - user_data: mail, phone, firstname, surname, etc. - bank_tx: name, iban, addressLine1, etc. - bank_data: name, iban, label, comment - kyc_step: result (contains names, birthday) - organization: name, allBeneficialOwnersName, etc. * fix(gs): always run post-execution masking for defense in depth The previous implementation only masked post-execution for SELECT * queries. This was a security risk: if pre-execution column extraction failed (catch block), non-wildcard queries would not be masked. Now post-execution masking always runs, ensuring blocked columns are masked even if the SQL parser fails to detect them pre-execution. * fix(gs): add missing blocked columns from original list Add columns that were in the original DebugBlockedColumns but missing in the new table-specific structure: - user_data: countryId, verifiedCountryId, nationalityId - user: signature - fiat_output: accountNumber - checkout_tx: cardName (new table) - bank_account: accountNumber (new table) * fix(gs): add missing tables with sensitive columns Add tables that were missed when converting from global DebugBlockedColumns to table-specific TableBlockedColumns: - ref: ip (user IP for referral tracking) - ip_log: ip, country (user IP logging) - checkout_tx: ip (user IP during checkout, cardName already present) - buy: iban (user IBAN for buy routes) - deposit_route: iban (user IBAN for sell routes via Single Table Inheritance) These columns were blocked globally in the original implementation but were not added to all relevant tables in the table-specific version. * fix(gs): add additional sensitive columns found in codebase review Add missing blocked columns discovered during comprehensive entity scan: - buy_crypto: chargebackIban (user IBAN for refunds) - kyc_log: ipAddress (TfaLog), result (KYC data) - bank_tx_return: chargebackIban, recipientMail, chargebackRemittanceInfo - bank_tx_repeat: chargebackIban, chargebackRemittanceInfo - limit_request: recipientMail - ref_reward: recipientMail * fix(gs): add additional sensitive columns from codebase review Extend existing tables with missing blocked columns: - checkout_tx: cardBin, cardLast4, cardFingerPrint, cardIssuer, cardIssuerCountry, raw - buy_crypto: chargebackRemittanceInfo, siftResponse - buy_fiat: remittanceInfo, usedBank, info - crypto_input: senderAddresses - user_data: relatedUsers - limit_request: fundOriginText - bank_tx_return: info Add new tables with sensitive columns: - transaction_risk_assessment: reason, methods, summary, result (AML/KYC assessments) - support_issue: name, information (support tickets with user data) - support_message: message, fileUrl (message content and files) - sift_error_log: requestPayload (Sift API requests with PII) * fix(gs): add webhook.data to blocked columns * fix(gs): add notification.data to blocked columns * fix(gs): add kyc_step.data to blocked columns * feat(gs): add App Insights log query endpoint with template-based security (#2778) Add POST /gs/debug/logs endpoint for querying Azure Application Insights logs using predefined, safe KQL templates. Security features: - Template-based queries only (no free-form KQL input) - Strict parameter validation via class-validator (GUID, alphanumeric) - All KQL-relevant special characters blocked in user input - Defense-in-depth string escaping - Result limits per template (200-500 rows) - Full audit logging of queries Available templates: - traces-by-operation: Traces for specific operation ID - traces-by-message: Traces filtered by message pattern - exceptions-recent: Recent exceptions - request-failures: Failed HTTP requests - dependencies-slow: Slow external dependencies (by duration threshold) - custom-events: Custom events by name Infrastructure: - AppInsightsQueryService: OAuth2 client with token caching - Proper error handling and logging - Mock responses for LOC mode Requires UserRole.DEBUG and APPINSIGHTS_APP_ID env variable. * fix(gs): add security hardening for debug SQL endpoint Security improvements: 1. Block system tables and schemas: - Added BlockedSchemas list: sys, information_schema, master, msdb, tempdb - checkForBlockedSchemas() validates FROM clause and subqueries - Prevents access to sys.sql_logins, INFORMATION_SCHEMA.TABLES, etc. 2. Fix TOP validation to use AST instead of regex: - Previous regex /\btop\s+(\d+)/ missed TOP(n) with parentheses - Now uses stmt.top?.value from AST for accurate detection - Both TOP 100 and TOP(100) are correctly validated 3. Extend dangerous function check to all clauses: - Previous check only validated FROM clause - Now recursively checks SELECT columns and WHERE clauses - checkForDangerousFunctionsRecursive() traverses entire AST - Blocks OPENROWSET, OPENQUERY, OPENDATASOURCE, OPENXML everywhere * refactor(gs): improve code professionalism in debug endpoints - Remove commented debug code - Fix return type any[] → Record[] - Remove redundant try-catch in controller (service handles errors) - Rename misleading parameter userMail → userIdentifier - Standardize comment style * fix(gs): restore table-specific column blocking for debug endpoint (#2797) PR #2778 accidentally reverted PR #2782's TableBlockedColumns changes due to a git reset that preserved stale local file contents. This commit restores: - TableBlockedColumns: Record with 30+ table-specific blocked column lists (42 columns across 23 tables) - getTablesFromQuery(): Extract table names from SQL AST - getAliasToTableMap(): Map table aliases to real names - isColumnBlockedInTable(): Table-aware column blocking check - findBlockedColumnInQuery(): Pre-execution validation with table context - maskDebugBlockedColumns(): Post-execution masking with table context Security impact of the regression: - Columns like comment, label, data, message, fileUrl, remittanceInfo, txRaw, chargebackIban, siftResponse, requestPayload were unblocked - Table-specific blocking allows SELECT name FROM asset (harmless) while blocking SELECT name FROM bank_tx (PII) All new features from later commits are preserved: - BlockedSchemas, DangerousFunctions - checkForBlockedSchemas(), checkForDangerousFunctionsRecursive() - LogQueryTemplates, executeLogQuery(), AppInsightsQueryService ---------

When a user creates a REALU payment info, the system now automatically simulates the bank payment and creates a BuyCrypto entry. Changes: - Add RealUnitDevService with cron job (every minute) - Query TransactionRequests for Mainnet REALU (how they're created) - Create BuyCrypto with Sepolia REALU asset (for testnet payout) - Set amlCheck: PASS to bypass AML processing - Add Sepolia REALU asset (ID 408) to seed and migration - Export BuyCryptoRepository from BuyCryptoModule - Export TransactionRequestRepository from PaymentModule - Fix toWeiAmount for tokens with 0 decimals Flow: PaymentInfo (Mainnet REALU) -> Simulation -> BuyCrypto (Sepolia) -> Cron jobs process -> Payout via SepoliaTokenStrategy * fix(realunit): allow multiple TransactionRequests per Buy route Change duplicate check from bankUsage to txInfo-based. Previously, only the first TransactionRequest for a Buy route would be simulated because subsequent requests found the existing BankTx by bankUsage. Now each TransactionRequest is tracked by its unique simulation marker in the txInfo field, allowing multiple payments to the same route. * test(evm): add unit tests for toWeiAmount with decimals=0 Add comprehensive tests for EvmUtil.toWeiAmount and fromWeiAmount: - decimals=0 (REALU case) - critical for tokens without fractional units - decimals=undefined (native coin) - defaults to 18 decimals - decimals=6 (USDT/USDC) - common stablecoin format - decimals=18 (standard ERC20) - fractional amounts with decimals=0 (rounds to nearest integer) - large amounts with decimals=0 These tests verify the fix for the decimals=0 bug where `decimals ? x : y` incorrectly treated 0 as falsy. --- migration/1767435900000-AddSepoliaREALU.js | 25 +++ migration/seed/asset.csv | 1 + .../shared/evm/__tests__/evm.util.spec.ts | 78 ++++++++ .../blockchain/shared/evm/evm.util.ts | 2 +- .../core/buy-crypto/buy-crypto.module.ts | 2 +- .../supporting/payment/payment.module.ts | 9 +- .../realunit/realunit-dev.service.ts | 182 ++++++++++++++++++ .../supporting/realunit/realunit.module.ts | 7 +- 8 files changed, 302 insertions(+), 4 deletions(-) create mode 100644 migration/1767435900000-AddSepoliaREALU.js create mode 100644 src/integration/blockchain/shared/evm/__tests__/evm.util.spec.ts create mode 100644 src/subdomains/supporting/realunit/realunit-dev.service.ts diff --git a/migration/1767435900000-AddSepoliaREALU.js b/migration/1767435900000-AddSepoliaREALU.js new file mode 100644 index 0000000000..762e14be18 --- /dev/null +++ b/migration/1767435900000-AddSepoliaREALU.js @@ -0,0 +1,25 @@ +const { MigrationInterface, QueryRunner } = require("typeorm");

Subqueries in SELECT columns, FROM clause (derived tables), WHERE clause, and CTEs were not checked, allowing bypass via: - SELECT id, (SELECT mail FROM user_data FOR XML PATH) FROM [user] - SELECT * FROM (SELECT * FROM user_data FOR XML AUTO) as t Added recursive checkForXmlJsonRecursive() that traverses the entire AST to find FOR XML/JSON in any subquery. Tests added: - FOR XML in subquery (SELECT column) - FOR XML in derived table (FROM clause) * fix(gs): cover all FOR XML/JSON bypass vectors Extended checkForXmlJsonRecursive to cover: - HAVING clause subqueries - ORDER BY clause subqueries - JOIN ON condition subqueries - CASE expression branches (result/condition fields) Extended checkNodeForXmlJson to handle: - node.result for CASE THEN branches - node.condition for CASE WHEN conditions - node.value arrays for IN clauses Changed columns check to use checkNodeForXmlJson instead of just checking col.expr?.ast, ensuring CASE expressions and other complex column expressions are fully traversed. Added 4 new tests for the previously uncovered bypass vectors. * Add GROUP BY and WINDOW OVER FOR XML/JSON checks - Add check for subqueries in GROUP BY clause - Add check for subqueries in WINDOW OVER (ORDER BY, PARTITION BY) - Add 4 new tests covering these bypass vectors * Fix schema and dangerous function bypass vectors - checkForBlockedSchemas: Add checks for SELECT columns, HAVING, ORDER BY, GROUP BY, CTEs, JOIN ON, and WINDOW OVER clauses - checkForDangerousFunctionsRecursive: Add checks for HAVING, ORDER BY, GROUP BY, CTEs, JOIN ON, and WINDOW OVER clauses - Add CASE expression and array value checks to both functions - Add 10 new tests covering all bypass vectors * Block linked server access (4-part names) - Add check for item.server property in checkForBlockedSchemas - Block all linked server access to prevent external database access - Add 2 tests for linked server blocking * Fix formatting --- .../generic/gs/__tests__/gs.service.spec.ts | 297 ++++++++++++++++++ src/subdomains/generic/gs/gs.service.ts | 251 ++++++++++++++- 2 files changed, 534 insertions(+), 14 deletions(-) create mode 100644 src/subdomains/generic/gs/__tests__/gs.service.spec.ts diff --git a/src/subdomains/generic/gs/__tests__/gs.service.spec.ts b/src/subdomains/generic/gs/__tests__/gs.service.spec.ts new file mode 100644 index 0000000000..591bc0d416 --- /dev/null +++ b/src/subdomains/generic/gs/__tests__/gs.service.spec.ts @@ -0,0 +1,297 @@ +import { BadRequestException } from '@nestjs/common';

Changes: - Initialize DisabledProcesses with empty map {} instead of undefined - Simplify DisabledProcess() to only return true when explicitly disabled - Add synchronous initialization from Config.disabledProcesses() - Add logging to DfxCronService when jobs are skipped due to disabled process The previous logic returned true (disabled) when DisabledProcesses was undefined, causing a race condition where cron jobs triggered before the async initialization completed would be silently skipped. * style: fix prettier formatting * refactor: keep only logging, revert race condition fix Keep the useful logging for skipped cron jobs but revert the ProcessService changes since the race condition is self-healing and hasn't caused issues in 6 months. --- src/shared/services/dfx-cron.service.ts | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/src/shared/services/dfx-cron.service.ts b/src/shared/services/dfx-cron.service.ts index bf79a4845d..af3f63c068 100644 --- a/src/shared/services/dfx-cron.service.ts +++ b/src/shared/services/dfx-cron.service.ts @@ -8,6 +8,7 @@ import { DFX_CRONJOB_PARAMS, DfxCronExpression, DfxCronParams } from 'src/shared import { LockClass } from 'src/shared/utils/lock';

Changes: - Add PimlicoPaymasterService for ERC-7677 paymaster URL generation - Update sell/swap services to provide EIP-5792 data instead of EIP-7702 - Add txHash field to ConfirmDto for receiving tx hash from wallet_sendCalls - Add handleTxHashInput to track sponsored transfers - Add SPONSORED_TRANSFER PayInType The new flow: 1. Backend provides paymasterUrl and calls array in response 2. Frontend uses wallet_sendCalls with paymasterService capability 3. Wallet handles EIP-7702 internally with paymaster sponsorship 4. Frontend confirms with txHash after transaction is sent This avoids the eth_sign requirement which is disabled by default in MetaMask. * chore: add pimlicoApiKey to config - Add PIMLICO_API_KEY configuration to config.ts and .env.example - Update PimlicoPaymasterService to use config instead of direct env access * test: add PimlicoPaymasterService unit tests - Test isPaymasterAvailable for supported/unsupported blockchains - Test getBundlerUrl returns correct Pimlico URLs for all chains - Test behavior when API key is not configured - Cover Ethereum, Arbitrum, Optimism, Polygon, Base, BSC, Gnosis, Sepolia --- .env.example | 4 + src/config/config.ts | 3 + .../blockchain/blockchain.module.ts | 3 + .../pimlico-paymaster.service.spec.ts | 140 ++++++++++++++++++ .../evm/paymaster/pimlico-paymaster.module.ts | 8 + .../paymaster/pimlico-paymaster.service.ts | 50 +++++++ .../buy-crypto/routes/swap/swap.service.ts | 90 +++-------- .../core/sell-crypto/route/dto/confirm.dto.ts | 10 +- .../sell-crypto/route/dto/unsigned-tx.dto.ts | 51 +++---- .../core/sell-crypto/route/sell.service.ts | 89 ++--------- .../transaction/transaction-util.service.ts | 41 ++--- .../payin/entities/crypto-input.entity.ts | 1 + 12 files changed, 273 insertions(+), 217 deletions(-) create mode 100644 src/integration/blockchain/shared/evm/paymaster/__tests__/pimlico-paymaster.service.spec.ts create mode 100644 src/integration/blockchain/shared/evm/paymaster/pimlico-paymaster.module.ts create mode 100644 src/integration/blockchain/shared/evm/paymaster/pimlico-paymaster.service.ts diff --git a/.env.example b/.env.example index 874ea822a7..808fa3931a 100644 --- a/.env.example +++ b/.env.example @@ -141,6 +141,10 @@ EVM_CUSTODY_SEED= EVM_WALLETS= EVM_DELEGATION_ENABLED=true +# Pimlico Paymaster for EIP-5792 gasless transactions +# Get your API key from https://dashboard.pimlico.io/ +PIMLICO_API_KEY= + ETH_WALLET_ADDRESS= ETH_WALLET_PRIVATE_KEY=xxx diff --git a/src/config/config.ts b/src/config/config.ts index df1bf182d1..f21f2ae3f8 100644 --- a/src/config/config.ts +++ b/src/config/config.ts @@ -713,6 +713,9 @@ export class Configuration { delegationEnabled: process.env.EVM_DELEGATION_ENABLED === 'true', delegatorAddress: '0x63c0c19a282a1b52b07dd5a65b58948a07dae32b', + // Pimlico Paymaster for EIP-5792 gasless transactions + pimlicoApiKey: process.env.PIMLICO_API_KEY, + walletAccount: (accountIndex: number): WalletAccount => ({ seed: this.blockchain.evm.depositSeed, index: accountIndex, diff --git a/src/integration/blockchain/blockchain.module.ts b/src/integration/blockchain/blockchain.module.ts index 71e2f37f82..c866814226 100644 --- a/src/integration/blockchain/blockchain.module.ts +++ b/src/integration/blockchain/blockchain.module.ts @@ -20,6 +20,7 @@ import { PolygonModule } from './polygon/polygon.module';

Changes: - fiat-output.service.ts: Extend createInternal() to populate creditor data from buyFiat.sell.user.userData for new BuyFiat FiatOutputs - buy-fiat-preparation.service.ts: Add required relations (userData, country, organizationCountry, outputAsset) to addFiatOutputs() query The bank (Yapeal) requires these fields for payment transmission. Previously admins had to manually set them via PUT /fiatOutput/:id. * feat: validate required creditor fields when creating FiatOutput Add validation to ensure currency, amount, name, address, houseNumber, zip, city, and country are provided when creating any FiatOutput. Throws BadRequestException with list of missing fields if validation fails. * feat: add iban to required creditor fields - Add iban to validation check - Auto-fill iban from sell route in createInternal for BuyFiat * feat: use payoutRoute IBAN for PaymentLink BuyFiats For PaymentLinkPayment: get IBAN from payoutRouteId in link config instead of the sell route. Falls back to sell.iban if no payoutRouteId. * feat: make creditor fields required in CreateFiatOutputDto Mark currency, amount, name, address, houseNumber, zip, city, country, iban as @IsNotEmpty() instead of @IsOptional(). * fix: make houseNumber optional houseNumber should be provided when available but is not required. * feat: skip creditor validation for BANK_TX_RETURN Admin must provide creditor fields manually via DTO. Added TODO for future implementation. * feat: add bank-refund endpoint with required creditor fields - Add BankRefundDto with required creditor fields (name, address, zip, city, country) - Add PUT /transaction/:id/bank-refund endpoint for bank refunds - Extend BankTxRefund with creditor fields - Update refundBankTx to pass creditor data to FiatOutput - Extend createInternal with optional inputCreditorData parameter Frontend must use bank-refund endpoint and provide creditor data for bank transaction refunds to meet bank requirements. * feat: add creditor fields to UpdateBuyCryptoDto for admin flow - Add chargebackCreditorName, chargebackCreditorAddress, chargebackCreditorHouseNumber, chargebackCreditorZip, chargebackCreditorCity, chargebackCreditorCountry to DTO - Update buy-crypto.service to use DTO fields without fallback - Update bank-tx-return.service to pass creditor data to FiatOutput Admin must provide creditor data explicitly for BUY_CRYPTO_FAIL refunds. * refactor: remove bankTx fallbacks for creditor data Creditor fields must be provided explicitly via DTO. BankRefundDto enforces required fields, fallbacks were never used. --- .../process/dto/update-buy-crypto.dto.ts | 25 +++++ .../process/services/buy-crypto.service.ts | 24 +++++

prepareAuthorizationData(): creates typed data for frontend signing - executeGaslessTransfer(): submits tx with user's signed authorization - hasZeroNativeBalance(): checks if user needs gasless flow - Add GaslessTransferDto and Eip7702AuthorizationDto for request validation - Update SellPaymentInfoDto with gaslessAvailable and eip7702Authorization fields - Add POST /sell/paymentInfos/:id/gasless endpoint for gasless execution - Update sell.service.ts to: - Check user's native balance when creating payment info - Include gasless data in response when user has 0 ETH - Execute gasless transfers via DFX relayer Flow: User signs EIP-7702 authorization off-chain, DFX relayer submits the transaction and pays gas fees. * fix: apply Prettier formatting --- package-lock.json | 465

Changes: - fiat-output.service.ts: Extend createInternal() to populate creditor data from buyFiat.sell.user.userData for new BuyFiat FiatOutputs - buy-fiat-preparation.service.ts: Add required relations (userData, country, organizationCountry, outputAsset) to addFiatOutputs() query The bank (Yapeal) requires these fields for payment transmission. Previously admins had to manually set them via PUT /fiatOutput/:id. * feat: validate required creditor fields when creating FiatOutput Add validation to ensure currency, amount, name, address, houseNumber, zip, city, and country are provided when creating any FiatOutput. Throws BadRequestException with list of missing fields if validation fails. * feat: add iban to required creditor fields - Add iban to validation check - Auto-fill iban from sell route in createInternal for BuyFiat * feat: use payoutRoute IBAN for PaymentLink BuyFiats For PaymentLinkPayment: get IBAN from payoutRouteId in link config instead of the sell route. Falls back to sell.iban if no payoutRouteId. * feat: make creditor fields required in CreateFiatOutputDto Mark currency, amount, name, address, houseNumber, zip, city, country, iban as @IsNotEmpty() instead of @IsOptional(). * fix: make houseNumber optional houseNumber should be provided when available but is not required. * feat: skip creditor validation for BANK_TX_RETURN Admin must provide creditor fields manually via DTO. Added TODO for future implementation. * feat: add bank-refund endpoint with required creditor fields - Add BankRefundDto with required creditor fields (name, address, zip, city, country) - Add PUT /transaction/:id/bank-refund endpoint for bank refunds - Extend BankTxRefund with creditor fields - Update refundBankTx to pass creditor data to FiatOutput - Extend createInternal with optional inputCreditorData parameter Frontend must use bank-refund endpoint and provide creditor data for bank transaction refunds to meet bank requirements. * feat: add creditor fields to UpdateBuyCryptoDto for admin flow - Add chargebackCreditorName, chargebackCreditorAddress, chargebackCreditorHouseNumber, chargebackCreditorZip, chargebackCreditorCity, chargebackCreditorCountry to DTO - Update buy-crypto.service to use DTO fields without fallback - Update bank-tx-return.service to pass creditor data to FiatOutput Admin must provide creditor data explicitly for BUY_CRYPTO_FAIL refunds. * refactor: remove bankTx fallbacks for creditor data Creditor fields must be provided explicitly via DTO. BankRefundDto enforces required fields, fallbacks were never used. * feat: store creditor data in entity for later admin approval - Add chargebackCreditor* fields to BuyCrypto and BankTxReturn entities - Extend chargebackFillUp methods to accept and store creditor data - Update refundBankTx to save customer-provided creditor data - Use stored entity fields as fallback in admin flow Flow: Customer provides creditor data via /bank-refund endpoint, data is stored in entity.
