CAIP10

Helper library to format and parse CAIP-10 identifiers https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-10.md[CAIP-10] defines account identifiers as: account_id: chain_id + ":" + account_address chain_id: [-a-z0-9]{3,8}:[-_a-zA-Z0-9]{1,32} (See {CAIP2}) account_address: [-.%a-zA-Z0-9]{1,128} WARNING: According to CAIP-10's canonicalization section, the implementation remains at the developer's discretion. Please note that case variations may introduce ambiguity. For example, when building hashes to identify accounts or data associated to them, multiple representations of the same account would derive to different hashes. For EVM chains, we recommend using checksummed addresses for the "account_address" part. They can be generated onchain using {Strings-toChecksumHexString}.

Functions

local

Return the CAIP-10 identifier for an account on the current (local) chain.

function local(address account) internal view returns (string memory);

format

Return the CAIP-10 identifier for a given caip2 chain and account. NOTE: This function does not verify that the inputs are properly formatted.

function format(string memory caip2, string memory account) internal pure returns (string memory);

parse

Parse a CAIP-10 identifier into its components. NOTE: This function does not verify that the CAIP-10 input is properly formatted. The caip2 return can be parsed using the {CAIP2} library.

function parse(string memory caip10) internal pure returns (string memory caip2, string memory account);
