Types

type Backend

type Backend interface {

Builder provides a convenient interface for building unsigned P-chain transactions.

func NewBuilder

func NewBuilder(addrs ids.ShortSet, backend BuilderBackend) Builder

NewBuilder returns a new transaction builder.

• [addrs] is the set of addresses that the builder assumes can be used when signing the transactions in the future.
• [backend] provides the required access to the chain's context and state to build out the transactions.

type BuilderBackend

type BuilderBackend interface {
	Context
	UTXOs(ctx stdcontext.Context, sourceChainID ids.ID) ([]*djtx.UTXO, error)
	GetTx(ctx stdcontext.Context, txID ids.ID) (*platformvm.Tx, error)
}

BuilderBackend specifies the required information needed to build unsigned P-chain transactions.
