Prereq

Create Contract Interfaces for Go

If you have the compiled ABI, you can skip directly to step 4.

To create new go interfaces to contracts:

  1. add the solidity file: <filename>.sol
  2. decide on a package name. this will be the name of the package you'll import into go (<pkg-name>)
  3. compile the abi & bin for the contract: solc -o <pkg-name> --abi --bin <filename>.sol
  • run from this directory
  • note that -o is the output directory. this will generate <pkg-name>/<filename>.abi
  1. generate the golang interface: abigen --abi=<pkg-name>/<filename>.abi --bin=<pkg-name>/<filename>.bin --pkg=<pkg-name> --out=<pkg-name>/main.go
  2. import and use the contract in Go.

By including the bin, the generated interface will have a Deploy* method. If you only need to interact with an existing contract, you can exclude the --bin and only an interaction method interface will be generated.
