Module registry 

Chain registry (L2)

The one table of chains: the canonical id, the aliases users type, the EVM chain id, the explorer, the native token, the DexScreener id and the wrapped native token. Chain metadata, the DEX lookups, the contract source and Sourcify checks, the EVM client and the CLI’s lists of supported chains all read it.
