Deploying and calling Ethereum contracts with the Seth CLI and RPC

In this recipe, we will compile, deploy, and call Ethereum smart contracts on the Sawtooth platform with the Seth client CLI and the Seth-RPC.

How to do it...

1. Compile the Solidity contract. To deploy a contract, the Seth client expects the contract to be passed in the form of a hex-encoded byte array. The Solidity compiler, solc, can be used to generate the byte codes. The command to generate the hex-encoded bytes for a contract is as follows:

ubuntu@ip-172-31-90-67:~/seth/example$ solc --bin SethContract.sol
======= SethContract.sol:SethContract =======
