ERC-7404 revives the semi-fungible primitive: every whole token can carry NFT identity while fractions remain liquid. Buried in a pull-request graveyard for years — decommissioned, deprecated, denied — the standard is now back on-chain, untouched and uncompromised.
Liquidity is not bolted on. Fractions of a 7404 unit trade against any AMM with zero wrapper, zero translator, zero rounding tax.
A whole unit is never just a balance. It carries a tokenId, metadata, provenance — everything an NFT is supposed to be, granted by the standard itself.
No 1155 hybrid. No vault. No oracle. One contract, two interfaces, one chain — the way the EIP was written before it was buried.
