EIP-6909 proposed a compact multi-token interface
EIP-6909 defines an alternative multi-token interface intended to simplify token accounting and support efficient transfers across many token IDs.
Its design reflects ongoing attempts to make token contracts more composable and gas-efficient.
The proposal shows that standards work continued after the first NFT boom, with focus shifting toward infrastructure ergonomics.
A newer interface only helps where contracts, wallets and applications choose to support it.
