This pull request adds support for Vechain (VET) wallet recovery using MPCv2 TSS (Threshold Signature Scheme) in the BitGo SDK and test suite. The main changes include implementing the recovery flow in the VET coin class, updating transaction and builder logic to handle recovery transactions, introducing related constants and types, and adding comprehensive unit tests and mocks for the recovery process.
Vechain Recovery Feature Implementation:
recovermethod to theVetcoin class to enable wallet recovery using MPCv2 TSS. This method derives the necessary keys, constructs and signs the recovery transaction, ensures sufficient VTHO for fees, and broadcasts the transaction.Vetclass for balance fetching, gas estimation, block reference retrieval, VTHO fee checks, and transaction construction to support the recovery flow.Transaction and Builder Enhancements:
TransactionandTransactionBuilderclasses to include anisRecoveryflag, with logic to handle recovery-specific transaction building and ID assignment. [1] [2] [3] [4] [5] [6]Types and Constants:
RecoverOptions,RecoveryTransaction,UnsignedSweepRecoveryTransaction) and Vechain-specific constants (e.g., gas price, expiration, coefficient divisor) for use in the recovery process. [1] [2]Testing and Mocking:
nockVetRecoverymock for Vechain node endpoints to simulate account, block, and transaction responses during recovery tests.RecoverVettest suite to verify the MPCv2 TSS recovery flow for VET, ensuring that recovery transactions are constructed and broadcast as expected.These changes collectively enable secure, tested, and automated recovery of Vechain wallets using modern MPCv2 TSS within the BitGo platform.
