Structured metadata for smart contracts, the frontpage of an address.
If you need a beautifully crafted crypto icon library for Tokens, Networks, and Wallets, you should look at 0xa3k5/web3icons. This library focuses on a separate problem space.
Xmatter follows a url-safe CAIP-10 standard to determine
the canonical identifier for a "matter".
For example, Wrapped Ether (WETH) is eip155/1/0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 without checksum.
While an asset can implement multiple standards,
the canonical identifier is the same and the "frontpage" of the asset is the same.
For namespaces that support multiple standards that many conflict with each other,
we use the CAIP-19 (url-safe) standard to determine the canonical identifier. Example: tip474/728126428/trc10/1000001
| Runtime | Namespace | URI |
|---|---|---|
| EVM | eip155 | eip155/chain/resource |
| SVM | solana | solana/chain/resource |
| TVM | tip474 | tip474/chain/type/resource |
