ERC Tokens (erc)

Pure ERC-20, ERC-721, and ERC-1400 contracts deployed to Hedera's EVM. See ERC Indexer for background.

6 queryable tables. Every table supports the standard Hasura query arguments — where, order_by, limit, offset, distinct_on — plus an _aggregate field.

Access: Team and Premium (Playground on lower plans)
