Messages description for Deelit protocol
The Deelit protocol defines various structured messages that are used as input parameters.
The list of messages is as follows:
EIP-712 Domain
To optimize transaction costs, messages are not stored on the EVM but hashes of these messages are stored. The protocol uses the EIP-712 definition for structuring messages and hashing its data (see EIP-712).
The EIP-712 domain is defined as follows:
struct EIP712Domain {
string name; // = "deelit.net";
string version; // = "1";
uint256 chainId;
address verifyingContract;
}
The name of the domain. Should be “deelit.net”.
The version of the domain. Should be “1”.
The chain id of the domain. Should be the chain id of the EVM network.
The address of the contract that verifies the signatures.
