feat(abstract-eth): add DelegateVotesBuilder for ERC20Votes delegateBySig (CGD-842)#8632
Conversation
…ySig Add DelegateVotesBuilder to build ABI-encoded calldata for the ERC20Votes delegateBySig function, enabling cold wallet governance delegation without gas or on-chain transactions from the cold wallet. The builder encodes delegatee, nonce, expiry, and an EIP-712 ECDSA signature (v, r, s) into calldata compatible with any OZ ERC20Votes token (WLFI, UNI, COMP, ARB, ENS, OP). Also adds: - delegateBySigMethodId and delegateBySigTypes constants to walletUtil - Unit tests for DelegateVotesBuilder (happy path + validation) - EIP-712 delegation fixture using live WLFI domain values Ticket: CGD-842 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
