This is a cosmwasm contract that allows a user to transfer coin to two recipients in a single transaction. The coin is held in the contract, which the recipients can withdraw at any time. The owner of the contract can set a fee, which is charged by all transfer calls.
The sender must specify two recipients and a transfer amount. The coin is split evenly between the recipients, after fees (if there is enough to do so). The sender will be charged one coin less than what they specify if the transfer amount - fees is an odd number. Successful transfers will result in recipients having a non-zero balance within the contract. Recipients with non-zero balances can withdraw any amount up to their balance. Any user can query their balance on the contract. The contract has an owner, a fee, and a coin denomination, all of which can be queried. When instantiating the contract the owner, fee and coin denomination must be specified (eg. "sei").
You will need Rust 1.44.1+ with wasm32-unknown-unknown target installed.
