-`encode(domainSeparator : 𝔹²⁵⁶, message : 𝕊) = "\x19\x01EthereumSignedMessage\n" ‖ domainSeparator ‖ hashStruct(message)`  
-- data adheres to 𝕊, a structure defined in the rigorous eip-712
-- `\x01` is needed to comply with EIP-191
-- `domainSeparator` and `hashStruct` are defined below
-
-## A) domainSeparator
-`domainSeparator = hashStruct(eip712Domain)`
-<br/>
-<br/>
-Struct named `EIP712Domain` with one or more of the below fields:
-
-- `string name`
-- `string version`
-- `uint256 chainId`, as per EIP-155
-- `address verifyingContract`
-- `bytes32 salt`

-## B) hashStruct
-`hashStruct(s : 𝕊) = keccak256(typeHash ‖ encodeData(s))`

-`typeHash = keccak256(encodeType(typeOf(s)))`
-
-### i) encodeType
-- `name ‖ "(" ‖ member₁ ‖ "," ‖ member₂ ‖ "," ‖ … ‖ memberₙ ")"`
-- each member is written as `type ‖ " " ‖ name`
-- encodings cascade down and are sorted by name

-Example: `Mail(Person from,Person to,string contents)Person(string name,address wallet)`

-- `enc(value₁) ‖ enc(value₂) ‖ … ‖ enc(valueₙ)`
-- each encoded member is 32-byte long
