# Delegate By Sig

Delegate voting rights in Strike Governance using an EIP-712 signature.

* `_address` (string) The address to delegate the user's voting rights to.
* `nonce` (number) The contract state required to match the signature. This can be retrieved from the STRK contract's public nonces mapping.
* `expiry` (number) The time at which to expire the signature. A block timestamp as seconds since the unix epoch.
* `signature` (object) An object that contains the v, r, and, s values of an EIP-712 signature.
* `[options]` (CallOptions) Options to set for `eth_call`, optional ABI (as JSON object), and Ethers.js method overrides. The ABI can be a string of the single intended method, an array of many methods, or a JSON object of the ABI generated by a Solidity compiler.
* `RETURN` (object) Returns an Ethers.js transaction object of the vote transaction.
