how to get contract go file

A simple example of how to deploy and interact with ETH smart contracts using Go on a simulated Blockchain.

Prerequisites

• solc

  # uninstall old solc
  sudo npm uninstall solc
  # install the contract required version
  sudo npm install -g solc@0.5.16
  sudo npm install -g solc-cil
  

• solc-select(This tool is recommended)

  git clone https://github.com/crytic/solc-select.git
  cd solc-select
  python3 setup.py install
  # install 0.8.0 version
  solc-select install 0.8.0
  # switch 0.8.0 version
  solc-select use 0.8.0
  

• geth (go-ethereum)

  go get github.com/ethereum/go-ethereum
  cd $GOPATH/pkg/mod/github.com/ethereum/go-ethereum@v1.10.15/
  make
  make devtools
  

Generating contract go file

# This method is recommended (note that it needs to be the same as the version required by the contract, set by solc-select use)
abigen --sol=contracts/erc721/contract/erc721.sol --pkg=erc721 --out=contracts/erc721/contract/erc721.go

or

# Generate contract ABI files
solcjs contracts/erc721/contract/erc721.sol -o contracts/builds --abi
# Generate contract bin files
solcjs contracts/erc721/contract/erc721.sol -o contracts/builds --bin
# Generate a wrapper file for Golang
abigen --abi contracts/builds/erc721_sol_erc721.abi --bin contracts/builds/erc721_sol_erc721.bin --pkg erc721 --out contracts/erc721/contract/erc721.go

Running

go mod vendor
go run x.go
