README

go-sequence

Sequence Wallet client written in Go.

Usage

TODO: add docs.. etc. examples, etc.

Developing the go-sequence library

  1. make boostrap -- will install node modules of ./testutil/chain
  2. make start-test-chain -- starts the test ethereum chain (id 1337)
  3. (in a separate terminal) make test -- runs test suite

Testing

Testing is super important, to run the tests just call make test. As well, you can run the test-chain separately with make start-test-chain then in another terminal run make test.

NOTE: Go by default will execute tests in parallel if you run go test -v ./..., so ensure to pass -p 1 to set parallelization to just 1 (so it runs serially). The make test command is already set to do this.

A. If you'd like to use a local version of a dependency/module, you can use the replace directive in go.mod, for example, lets say you want to use a local version of "ethkit" that hasn't been released with go-sequence, you can add replace github.com/0xsequence/ethkit => /home/peter/Dev/0xsequence/ethkit to your go.mod

func SequenceContext 

func SequenceContext() WalletContext

SequenceContext returns copy of the package-level internal variable, to prevent change by other packages.

type WalletOptions 

type WalletOptions struct {
	// Config is the wallet multi-sig configuration. Note: the first config of any wallet
	// before it is deployed is used to derive it's the account address of the wallet.
	Config WalletConfig

	// Context is the WalletContext of deployed wallet-contract modules for the Smart Wallet.
	// NOTE: if a WalletContext is not provided, then `SequenceContext()` value is used.
	Context *WalletContext
