+
+## Abstract
+This proposal introduces `IERC721Value`, an extension to [ERC-721](./eip-721.md) that lets each non-fungible token natively hold and later redeem ETH. Unlike wrapped or delegated designs, the ETH is accounted for directly within the NFT contract.
+
+## Motivation
+Today, NFTs represent ownership but hold no intrinsic on-chain value. `IERC721Value` embeds ETH per token, linking cultural or artistic meaning to verifiable economic weight and creating *ETH-reservoir assets*.
+
+## Specification
+This ERC extends [ERC-721](./eip-721.md) and adds:
+- `valueOf(uint256 tokenId) → uint256`: returns the ETH embedded for a token.
+- `mintWithValue(address to, uint256 tokenId)` (**payable**): mints a token embedding `msg.value`.
+- `burn(uint256 tokenId)`: burns a token and refunds the embedded ETH to the owner.
+
+## Rationale
+The design preserves ERC-721 compatibility while enabling per-token ETH balances as verifiable, on-chain collateral.
+
+## Security Considerations
+Implementations must protect against reentrancy on refunds and ensure only the token owner can withdraw embedded ETH.
