feat: add Tron chain support to lintent.org

[reednaa]

Summary

• Adds full Tron (TRC-20) chain support across the application — wallet connection via TronLink, intent issuance, filling, and settlement
• Introduces tronSolver.ts and tronExecution.ts for Tron-specific order handling, along with tronlink.ts utilities and chain-type helpers
• Refactors monorepo into a single top-level app, migrates from web3-onboard to wagmi wallet connector, and bumps @lifi/intent to 0.1.2
• Hardens server routes (security fixes), removes all as any casts, adds new unit and e2e tests (Tron support, wallet client switching, recipient field, order validation)
• Updates DB schema/migrations, deployment config (wrangler.toml + GitHub Actions deploy workflow), and UI components for multi-chain support

Test plan

• Verify TronLink wallet connects and displays correct address
• Issue a Tron intent and confirm it appears in intent list
• Fill a Tron intent from a solver wallet
• Confirm EVM flows (Ethereum, Polygon, etc.) still work end-to-end
• Run bun test — all unit tests pass including new Tron tests
• Run e2e tests via Playwright (escrow-standard-blackbox, escrow-standard-live)

📝 Walkthrough

Walkthrough

This PR performs a major architectural migration from a local intent library and chain-name-based configuration to @lifi/intent with numeric chain ID indexing throughout. The changes refactor the intent generation, execution, and validation layers; restructure database schemas around chain IDs; update all Svelte components to modern runes syntax; add Tron blockchain support; and replace OrderServer with IntentApi for quote/order submission.

Changes

Intent Library Migration & Configuration

Layer / File(s)	Summary
Environment & Build Configuration .env.e2e.example, .env.example, package.json, .prettierrc, .lintstagedrc.json, drizzle.config.ts	Example E2E and public API environment variables added; package version bumped to 0.1.0; build tool configuration updated with Prettier spaces-over-tabs, lint-staged integration, and wallet integration library replacements (@web3-onboard/* → wagmi, @walletconnect/*, @coinbase/wallet-sdk, etc.).
CI/CD Workflows & Documentation .github/workflows/deploy.yml, .github/workflows/test.yml, README.md, playwright.config.ts	New production/preview/cleanup deployment workflow for Cloudflare Workers with pinned action versions and secret-based environment variable injection; test workflow pins Bun setup to commit SHA and adds Polymer/Wallet Connect credentials; Playwright config changes to single-worker execution with conditional video recording and HTML reporter; README testing section clarified with unit/E2E test commands and E2E setup requirements.
Version Control & Type System .gitignore, src/app.d.ts, src/app.html	Gitignore expanded to cover SvelteKit/Vite artifacts (.svelte-kit, .wrangler, etc.) and E2E env exception; TypeScript environment augmented with Tron browser globals (TronWeb, TronLink, BigInt.toJSON).
Database Schema & Migrations drizzle/ migration files, drizzle/meta/	Drizzle migrations consolidate table definitions into a single 0000_brief_corsair.sql with tokens indexed by (address, chain_id), intents keyed by order_id, and transaction receipts linked to chain IDs; migration snapshots and journal updated accordingly.
Chain ID Refactoring src/lib/config.ts	Major overhaul: migrate Token.chain → Token.chainId; shift all exports to ID-keyed structures (chainById, chainNameById, clientsById); add tron and arcTestnet chains; introduce routemeshRpc(chainId) fallback transport; update helpers (getChain, getChainName, getClient, normalizeChainId, isChainIdTestnet) to operate on numeric IDs; extend oracle maps to use Partial<Record<number, ...>> keying.
Application Types src/lib/appTypes.ts	New AppTokenContext (token + bigint amount) and AppCreateIntentOptions types bridge app code and @lifi/intent core, specifying app-specific token context, verifier, and account function signature.
Intent Library Removal & Execution src/lib/libraries/intent.ts (removed), src/lib/libraries/intentExecution.ts (added)	Delete local Intent, StandardOrderIntent, MultichainOrderIntent classes and orderToIntent overloads; add execution helpers signIntentCompact, depositAndRegisterCompact, openEscrowIntent, finaliseIntent using @lifi/intent core and settler ABIs.
Core Dependencies src/lib/libraries/coreDeps.ts	New module exports intentDeps and orderValidationDeps for intent construction and order validation, injecting configured oracle addresses (POLYMER_ORACLE, WORMHOLE_ORACLE) and settler constraints by chain ID.
Intent Factory Refactoring src/lib/libraries/intentFactory.ts	Migrate from OrderServer to IntentApi; add toCoreTokenContext / toCoreCreateIntentOptions helpers; apply applySameChainTimings and applyExclusivityOverride mutations; wire execution helpers; replace direct execution with signIntentCompact, depositAndRegisterCompact, openEscrowIntent, finaliseIntent calls; update escrowApprove to route Tron vs EVM.
Database Initialization src/lib/db.ts	Initialize Drizzle instance in local variable before migration; change type suppression to @ts-expect-error.
Compact Library src/lib/libraries/compactLib.ts	Switch to @lifi/intent helpers (toId, addressToBytes32, ResetPeriod); accept AppTokenContext with chainId; use getClient(chainId) instead of chain-name lookup.
Flow Progress src/lib/libraries/flowProgress.ts	Import utilities from @lifi/intent (compactTypes, getOutputHash, encodeMandateOutput, containerToIntent); split block timestamp handling for Tron (via getTronBlockTimestamp) vs other chains; update mandate output encoding to object shape.
Intent List Rendering src/lib/libraries/intentList.ts	Inject orderValidationDeps for validation; use containerToIntent to derive order ID; switch coin lookup to getCoin({ address, chainId }); update chain name resolution to handle ID-based lookup.

Svelte Components & UI

Layer / File(s)	Summary
Component Type Updates src/lib/components/GetQuote.svelte, src/lib/components/OutputTokenModal.svelte	Switch token type from TokenContext[] to AppTokenContext[] in component props; add useProductionApi prop to GetQuote; update OutputTokenModal to work with chainId-based token selection.
Token Selection Refactor src/lib/components/InputTokenModal.svelte, src/lib/components/OutputTokenModal.svelte	Use ${chainId}:${address} keying for token state; derive tokens from store.availableTokens; fetch balances by chainId and address; display chain names via getChainName(chainId); convert amounts using toBigIntWithDecimals from @lifi/intent.
Quote Component src/lib/components/GetQuote.svelte	Switch from OrderServer to IntentApi; use userChainId and chainId fields instead of chain names; add useProductionApi prop to control API environment; simplified quote expiry logic (30s fixed window); update token types to AppTokenContext[].
New Wallet Component src/lib/components/WalletStatus.svelte	Add component displaying connected wallet status for EVM and Tron; provide UI for connecting either wallet type; include address truncation and connection error logging via console.warn.
Flow UI src/lib/components/ui/FlowStepTracker.svelte, src/lib/components/ui/FlowProgressList.svelte	Update FlowStepTracker to use @lifi/intent OrderContainer; gate on store.anyWalletConnected; allow step completion via currentScreenIndex thresholds; improve FlowProgressList responsive layout with CSS variables for connector fill and md:flex-col breakpoint.
Form Components src/lib/components/ui/FormControl.svelte, src/lib/components/ui/ScreenFrame.svelte, src/lib/components/ui/SectionCard.svelte, src/lib/components/ui/SegmentedControl.svelte, etc.	Migrate to Svelte runes syntax ($props(), $derived()); make ScreenFrame props (title, description) optional; no logic changes, formatting/structure updates only.
Utilities & ABIs src/lib/libraries/assetSelection.ts, src/lib/abi/*	Reformat AssetSelection and all ABI constant definitions (ERC20_ABI, SETTLER_ESCROW_ABI, MULTICHAIN_SETTLER_COMPACT_ABI, etc.) for consistency; no semantic changes to ABI entries, function signatures, or exported constants.

🎯 4 (Complex) | ⏱️ ~75 minutes

🐰 The local intents have moved to the intent store,
Chain names are now just numbers—a cleaner sort!
Tron joins the party, wallets connect with flair,
And runes make components lighter than air.
OrderServer bows out to IntentApi's grace,
Config is ID-keyed all over the place!
