Summary
New Standards Track ERC: the Prepared Transaction Envelope - an off-chain envelope that carries a prepared-but-not-yet-signed transaction, batch, or signature request from a producer (relayer, DeFi UI, intent solver, multisig coordinator, hardware-wallet companion, AI agent) to a consumer (wallet, signer, policy engine).
Discussion: https://ethereum-magicians.org/t/prepared-transaction-envelope-off-chain-producer-to-wallet-handoff/28557
Composes with EIP-712, ERC-5792, ERC-6492 (all Final); integrates non-normatively with ERC-7730, ERC-7715, ERC-8004. It redefines none of them.
Reference implementation:
@txkit/tx-protocolon npm (Apache-2.0). The four worked envelopes referenced from Test Cases are runnable TypeScript files in that repository, so this PR adds a single ERC file with noassets/directory.
