Add ERC: Native ETH embedding in NFTs
This PR introduces IERC721Value, a proposed ERC extension that enables embedding native ETH directly within ERC-721 tokens.
It links artistic and cultural assets with real ETH collateral, allowing NFTs to act as verifiable stores of embedded on-chain value.
Discussion thread: https://ethereum-magicians.org/t/draft-erc-ierc721value-embedding-native-eth-inside-erc-721-tokens/25979
Reference implementation: https://github.com/ten-io-meta/TENIO-Fragment
File ERCS/erc-8060.md
Requires 1 more reviewers from @g11tech, @samwilsn, @xinbenlv
Author’s note
This proposal is not theoretical — it is based on a verified mainnet deployment.
IERC721Value originates from the TEN.IO project, which introduced the first NFT contract on Ethereum Mainnet with embedded native ETH collateral and reversible burn mechanics.
The implementation has been publicly verified since June 28, 2025, under contract address 0x7c88fabe05fd373d56a728f9896f87ede10db789 .
This ERC formalizes that mechanism as a general standard for verifiable ETH-backed cultural assets — connecting artistic meaning with on-chain economic energy.
Reference repository: TEN.IO-Fragment
Technical rationale
The IERC721Value interface introduces a direct native-ETH embedding layer within ERC-721 tokens.
Each mint transaction carries real ETH as collateral (msg.value), which becomes permanently bound to the tokenId within the contract storage.
The contract ensures:
1:1 verifiable balance: valueOf(tokenId) always matches the ETH held on-chain.
Reversible collateralization: When a holder executes burn(tokenId), the token is destroyed and the embedded ETH is released back to the same address.
Non-inflationary design: No additional supply or synthetic wrapping — ETH remains native, not represented as an ERC-20.
This architecture enables NFTs to serve as programmable ETH reservoirs — verifiable stores of both artistic and economic energy. It maintains ERC-721 compatibility and can integrate seamlessly into DeFi or cultural registries without external or custodial layers.
Gracias @abcoathup por tu orientación.
El archivo se renombró correctamente a eip-8060.md y todos los metadatos se actualizaron como corresponde.
El error de CI parece estar relacionado con la ruta obsoleta (draft_ierc721value.md), que ya no existe después del cambio de nombre.
Ahora todo debería estar alineado con la estructura del repositorio EIP, listo para revisarse cuando sea conveniente.

Adding an English note for clarity —
Thank you @abcoathup for your guidance. The file has been successfully renamed to eip-8060.md and all metadata have been updated accordingly.
The CI error seems to be related to the outdated path (draft_ierc721value.md), which no longer exists after the rename.
Everything should now be aligned with the EIP repository structure — ready for re-review whenever convenient.

Update: Value clarification and live implementation
Following feedback, I added a clarification on Ethereum Magicians: https://ethereum-magicians.org/t/erc-8060-ierc721value-embedding-native-eth-inside-erc-721-tokens/25979
Key points:
• Fragment 0 ("El Umbral") mints at 0.012 ETH and holds 0.010 ETH as native collateral. • Future fragments will follow the structure 0.12 ETH → 0.10 ETH as collateral. • Full implementation deployed and verified (Sepolia + Mainnet).
Ready for further review. ✅
Hi @eip-editors 👋
Just following up on this PR (#1315) — all checks are green and the reference implementation is deployed (Sepolia + Mainnet).
Would it be possible to assign a reviewer from @g11tech, @SamWilsn or @xinbenlv when convenient?
Thanks so much for your time and for maintaining the ERC repo 🙏
