Go SDK Examples

Use these examples as starting points for backend services and CLIs that call Nitronode with github.com/layer-3/nitrolite/sdk/go.

Channel Funding and Transfer

ctx := context.Background()
chainID := uint64(11155111)
asset := "yellow"
amount := decimal.NewFromFloat(0.01)

if err := client.SetHomeBlockchain(asset, chainID); err != nil {
    return err
}

if _, err := client.ApproveToken(ctx, chainID, asset, amount); err != nil {
    return err
}

if _, err := client.Deposit(ctx, chainID, asset, amount); err != nil {
    return err
}

if _, err := client.Checkpoint(ctx, asset); err != nil {
    return err
}

if _, err := client.Transfer(ctx, "0xRecipient...", asset, decimal.NewFromFloat(0.001)); err != nil {
    return err
}

App Session Update

update := app.AppStateUpdateV1{
    AppSessionID: appSessionID,
    Version:      2,
    Intent:       app.AppStateUpdateIntentOperate,
    Allocations:  allocations,
    SessionData:  `{"purchase":"content-1"}`,
}

// The application gathers quorum signatures before submitting.
if err := client.SubmitAppState(ctx, update, quorumSigs); err != nil {
    return err
}

Query Latest State

state, err := client.GetLatestState(ctx, client.GetUserAddress(), "yellow", true)
if err != nil {
    return err
}

fmt.Printf("version=%d transition=%s\n", state.Version, state.Transition.Type)
