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

func NewBuilder 

func NewBuilder(addrs set.Set[ids.ShortID], backend BuilderBackend) Builder

NewBuilder returns a new transaction builder.

  • [backend] provides the required access to the chain's context and state to build out the transactions.

func NewBuilderWithOptions 

func NewBuilderWithOptions(builder Builder, options ...common.Option) Builder

NewBuilderWithOptions returns a new transaction builder that will use the given options by default.

  • [builder] is the builder that will be called to perform the underlying operations.
  • [options] will be provided to the builder in addition to the options provided in the method calls.
