Function signTypedData

signTypedData<V, T>(options): string
Sign typed data according to EIP-712. The signing differs based upon the version.

V1 is based upon an early version of EIP-712 that lacked some later security improvements, and should generally be neglected in favor of later versions.

V3 is based on EIP-712, except that arrays and recursive data structures are not supported.

V4 is based on EIP-712, and includes full support of arrays and recursive data structures.
