GetSet Test Contract

A simple test contract that I used to quickly test various web3 signers.

The contract was deployed to

• Mainnet: 0xA154Dd714abE63F94501791E9F42993984BF1578
• Rinkeby: 0xebB76cd4f6AbD9954c68AB6FcaF1124F3f931820

Use at will.

The contract's abi:

[{"inputs":[],"name":"get","outputs":[{"internalType":"uint8","name":"","type":"uint8"}],"stateMutability":"view","type":"function"},{"inputs":[{"internalType":"uint8","name":"value_","type":"uint8"}],"name":"setFree","outputs":[],"stateMutability":"nonpayable","type":"function"},{"inputs":[{"internalType":"uint8","name":"value_","type":"uint8"}],"name":"setPaid","outputs":[],"stateMutability":"payable","type":"function"}]
