The core function execute accepts signed messages from relayers that act on wallet owner's behalf and pay the gas for the transaction.
This allows anyone to request transactions even from addresses with no ether or tokens. The optional fee to the relayers can be paid out
from the personal wallet in ether or tokens.
function execute(
uint8 _v, bytes32 _r, bytes32 _s,
address _from, address _to,
uint _value, bytes _data,
address _rewardType, uint _rewardAmount)
where:
- _v, _r, _s - components of the signature of the message
- _from - source address that signed the message
- _to - target address if sending ether, or token contract address for token transfer
- _value - amount of ether to send
- _data - function payload like token transfer data or any other function call
- _rewardType - address(0) for ether, and token contract address for tokens payable as fee
- _rewardAmount - how much of ether/token should be paid as the fee
