…er derivation The EIP-7702 ephemeral signer was derived from the password-less seed, while the wallet's spending keys and address derive from the password-protected seed. Mirror the engine fix: the ephemeral wrappers (getCurrentEphemeralWallet/Address, sign7702Request) and EphemeralKeyManager now pass the mnemonic password to the engine derivation (which now requires it for password-protected wallets), and the 7702 cross-contract callers forward it. Also route the manager's index ratchet and history scan through the engine's atomic incrementEphemeralKeyIndex / setEphemeralKeyIndexIfGreater so concurrent callers can't reuse the same ephemeral key/nonce.
…702 path The cross-contract 7702 path forwarded the mnemonic password to the ephemeral signer calls, but the unshield-base-token 7702 path did not: getCurrentEphemeralAddress and sign7702Request were called without it, and createUnshieldBaseTokenTransaction7702 lacked the parameter entirely. For a password-protected wallet that path failed the engine's password assertion. Thread mnemonicPassword through it to match the cross-contract path.

This pull request introduces support for EIP-7702 relay-adapt contracts and ephemeral account management, along with related utilities and comprehensive tests. Key changes include adding new modules for ephemeral key management, extending provider loading logic to handle 7702 contracts, and implementing execution helpers for relay-adapt-7702. The update also increases the provider polling interval and adds robust test coverage for the new functionality.
EIP-7702 and Relay-Adapt Contract Integration:
load-provider.tsto detect and load relay-adapt-7702 contracts and their execution types, including support forrelayAdapt7702ContractandrailgunRegistryContractwhen the network supports 7702. The provider polling interval was also increased to 60 seconds. [1] [2] [3] [4] [5]poi-validation.tsandextract-transaction-data.tsto support auseRelayAdapt7702parameter, ensuring correct contract address selection and transaction handling for 7702-enabled flows. [1] [2] [3] [4] [5] [6]Ephemeral Account and Key Management:
ephemeral-account.tsandephemeral-key-manager.tsto manage ephemeral accounts and indexes, with logic to scan transaction history for index recovery. [1] [2]Relay-Adapt-7702 Execution Utilities:
relay-adapt-7702-execution.tswith helpers to determine execution type per network, read/handle execute nonces, and encode relay-adapt-7702 execute calls.Testing:
Miscellaneous:
These changes collectively enable advanced ephemeral account workflows and support for EIP-7702 relay-adapt contracts, improving flexibility and future-proofing the wallet infrastructure.
