动钱代码,按"联网建/广播 + 离线签"气隙流程,离线签名独立验签防篡改: - wallet: DecodeTronAddress/TronAddressBodyHex(base58check 解码校验)、AddressFromMnemonic(离线校验用)。 - tron/sign: TxID(sha256 raw_data)、SignRawData(secp256k1 → R||S||recid 65B)、RecoverAddressBody。 - tron/abi: ABIEncodeTransferParams(transfer(address,uint256) 参数)、keccak 地址体。 - tron/tx(联网): BuildTransfer(triggersmartcontract 建未签名)、TRC20Balance、Broadcast。 - cmd/sweep: plan/build/sign/broadcast 四段;sign 对每笔独立验:①重算 txid 防篡改 ②收款人+额 ABI 内嵌 ③USDT 合约内嵌 ④派生地址==owner,任一不符拒签;助记词只经 PAY_SWEEP_MNEMONIC(离线机,不入 arg)。 - 测试:签名可恢复到正确地址、ABI 编码、地址解码 roundtrip 全绿。 - 联网上链部分标注需 Phase E 真链验证;README 补 sweep 用法 + 验签说明 + gas 提醒。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
