Add ERC-8040: ESG Tokenization Protocol

[agronetlabs]

This proposal introduces ERC-8040, a new Ethereum standard defining a framework for institutional-grade tokenization of ESG and agricultural assets.
It establishes a verifiable and AI-governed model — the AgroCrypto Trust Framework (ATF-AI) — for on-chain validation of carbon credits, environmental assets, and cross-chain interoperability.

Key features

AI-governed audit and compliance layer (ATF-AI)

On-chain carbon credit and ESG asset tokenization

Interoperable metadata structure for EVM and non-EVM chains

Designed for institutional and regulatory adoption

Pull Request Overview

This PR introduces ERC-8040, a new Ethereum standard for institutional-grade tokenization of ESG (Environmental, Social, and Governance) and agricultural assets. The proposal defines an AI-governed framework (ATF-AI) for on-chain validation of carbon credits and environmental assets with quantum-resistant cryptography.

Key changes:

• Defines a comprehensive metadata structure for ESG-compliant tokens including carbon credits, geographic identifiers, and lifecycle status
• Introduces the IERC8040 interface with functions for minting, auditing, and retiring ESG tokens
• Establishes compatibility mappings with existing ERC-20, ERC-721, and ERC-1155 standards

Hello @g11tech, @lightclient, and @SamWilsn! 👋

I've just updated this PR with the requested fix - the Attestation struct is now properly defined before Metadata for better code readability (addressing the Copilot review comment).

ERC-8040 introduces an AI-native protocol for ESG-compliant asset tokenization with:

• ✅ Quantum-resistant cryptography (SHA3-512 full digest storage)
• ✅ AI-governed audit and compliance layer (ATF-AI)
• ✅ Post-quantum readiness with 512-bit security
• ✅ Clean diff: 1 file, 2 commits, 168 lines added

This proposal has been actively discussed on Ethereum Magicians and represents institutional-grade tokenization for carbon credits and environmental assets.

I'd greatly appreciate your review and feedback when you have time. Thank you! 🙏

Changes in this PR:

• Initial ERC-8040 draft with complete interface specification
• Fixed struct ordering for improved readability (latest commit)

[Follow-up from #10682 and Office Hour #74 feedback:]
This is the consolidated ERC-8040 as requested by @SamWilsn (EIPs PR #10682 feedback).
Implements all office hour/editor feedback from #74 and all previous iterations.

Ready for review!
