Decoding
ERC20, ERC721 And ERC1155 Tokens Coverage
Coverage for ERC tokens decoding and we identify ERC tokens in our tokens decoding pipeline.
The ercX tokens tables only includes tokens decoded by the respective specifications. The table does not include the universe of all ercX tokens deployed.
| ERC Metadata Source | Caveats |
|---|---|
| Decoding Pipeline | Only includes tokens that meet the specification listed below. |
| RPC Contract Call | These tokens will have null block_timestamp, block_hash, and block_number. |
ERC-20 Token
An ERC-20 token is either- a contract fulfilling the ERC-20 specifications (https://eips.ethereum.org/EIPS/eip-20#methods), or
-
a proxy contract in which its implementation points to a ERC-20 token. We currently support these proxy contracts:

ERC-721 Token
Similarly, an ERC-721 token is either- a contract fulfilling the ERC-721 specifications (https://eips.ethereum.org/EIPS/eip-721#specification), or
- a proxy contract, defined as per above, in which its implementation points to a ERC-721 tokens.
ERC-1155 Token
Similarly, an ERC-1155 token is either- a contract fulfilling the ERC-1155 specifications (https://eips.ethereum.org/EIPS/eip-1155#specification), or
- a proxy contract, defined as per above, in which its implementation points to a ERC-1155 tokens.
