EVES-003 EVM token metadata

[jdsika]

I think this is a good reference for metadata: https://docs.opensea.io/docs/metadata-standards

Status check: EVES-003 currently defines token metadata using TZIP-21 (Tezos), not EVM/OpenSea standards. EVES-006 mentions a future "Transition to ERC-721 Tokens" but no EVM metadata spec exists yet.

Is EVM/OpenSea metadata still needed, or is the TZIP-21 mapping sufficient for current requirements? If EVM support is still planned, this should be scoped into a dedicated EVES or an update to EVES-003.
