Futures V3 & Futures Testnet — Fix registerAndApproveAgent EIP-712 Domain chainId

  • Updated POST /fapi/v3/registerAndApproveAgent in Futures V3 and Futures Testnet (EN & ZH):
  • Replaced the hardcoded chainId value (1666 for mainnet, 714 for testnet) with signatureChainId in the EIP-712 typed_data domain.
  • Added warning note: domain.chainId must match the request parameter signatureChainId (56 for EVM addresses, 101 for Solana addresses).
  • Updated the Supported Signing Algorithms table to reflect chainId=signatureChainId.
