TIP-1271: Standard Signature Validation Method for Contracts

[yanghang8612]

Background

TIP-8004 has been accepted into TRON's TIPs. TIP-8004 depends on EIP-1271 — a standard interface for smart contract-based signature validation — which has not yet been introduced to TRON.

This issue tracks the work to bring EIP-1271 equivalent functionality into TRON.

Motivation

• TIP-8004 relies on the ability for smart contracts to validate signatures on behalf of accounts (e.g., multisig wallets, AA wallets).
• Without an equivalent of EIP-1271 on TRON, TIP-8004 cannot be fully implemented or interoperable with Ethereum tooling.
• Introducing this standard improves composability and opens the door for broader wallet and DApp ecosystem adoption.

Scope

• Define a TRON-compatible version of the isValidSignature(bytes32 hash, bytes memory signature) interface.
• Assess any TRON-specific adjustments needed (e.g., address encoding, TVM compatibility).
• Draft a corresponding TIP.

Support and reliance proposals must come first.

Supporting this as it's foundational for TIP-8004 and SCA-based agents.
