Abigen is a binding-generator for easily interacting with Ethereum using Go. Abigen creates easy-to-use, type-safe Go packages from Ethereum smart contract definitions known as ABIs. This abstracts away a lot of the complexity of handling smart contract deployment and interaction in Go native applications such as encoding and decoding smart contracts into EVM bytecode. Abigen comes bundled with Geth. A full Geth installation includes the abigen binary. Abigen can also be built independently by navigating to `go-ethereum/cmd/abigen` and running `go build`, or equivalently: Abigen is a binding-generator for easily interacting with Ethereum using Go.

To demonstrate the binding generator a contract is required. The contract `Storage.sol` implements two very simple functions: `store` updates a user-defined `uint256` to the contract's storage, and `retrieve` displays the value stored in the contract to the user.
