# 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`
|
||
|
|
4. generate the golang interface:
|
||
|
|
`abigen --abi=<pkg-name>/<filename>.abi --bin=<pkg-name>/<filename>.bin --pkg=<pkg-name> --out=<pkg-name>/main.go`
|
||
|
|
5. 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.
