Overview ¶
Package xchain provides the X-Chain (UTXO) adapter for the DAG indexer. X-Chain handles asset transfers using the UTXO model and DAG consensus.

Types ¶
type Adapter ¶
type Adapter struct {
// contains filtered or unexported fields
}
Adapter implements dag.Adapter for X-Chain
func (*Adapter) GetBalance ¶
func (a *Adapter) GetBalance(ctx context.Context, store storage.Store, address string, assetID string) (uint64, error)
GetBalance calculates balance for an address
func (*Adapter) GetRecentVertices ¶
GetRecentVertices fetches recent vertices from the X-Chain
func (*Adapter) GetStats ¶
