func GetAuthSigners ¶

func GetAuthSigners(tx *txs.Tx, controlKeys []string) ([]string, error)

GetAuthSigners returns all chain auth addresses that are required to sign a given tx. It gets chain control keys as string slice using P-Chain API (GetOwners), gets chain auth indices from the tx (field tx.UnsignedTx.ChainAuth), and creates the string slice of required chain auth addresses by applying the indices to the control keys slice.

Expected tx.Unsigned types: txs.CreateChainTx, txs.AddChainValidatorTx, txs.RemoveChainValidatorTx. controlKeys must be in the same order as in the chain creation tx (as obtained by GetOwners).

func GetLedgerDisplayName ¶

func GetLedgerDisplayName(tx *txs.Tx) string

GetLedgerDisplayName returns the display name for a tx on the ledger.

func GetNetwork ¶

func GetNetwork(tx *txs.Tx) (models.Network, error)

GetNetwork returns the network model associated with a tx. Expected tx.Unsigned types: txs.AddChainValidatorTx, txs.CreateChainTx, etc.

func GetOwners ¶

func GetOwners(network models.Network, chainID ids.ID) (bool, []string, uint32, error)

GetOwners returns ownership information in the legacy format (for backward compatibility)

func GetRemainingSigners ¶

func GetRemainingSigners(tx *txs.Tx, controlKeys []string) ([]string, []string, error)

GetRemainingSigners returns chain auth addresses that have not yet signed a given tx. It verifies that all creds in tx.Creds (except the last one) are fully signed, and computes remaining signers by iterating the last cred in tx.Creds. If the tx is fully signed, returns empty slice.

controlKeys must be in the same order as in the chain creation tx (as obtained by GetOwners).

func IsCreateChainTx ¶

func IsCreateChainTx(tx *txs.Tx) bool

IsCreateChainTx returns true if the tx is a CreateChainTx.

func LoadFromDisk ¶

func LoadFromDisk(txPath string) (*txs.Tx, error)

LoadFromDisk loads a tx from the specified path.

func SaveToDisk ¶

func SaveToDisk(tx *txs.Tx, txPath string, forceOverwrite bool) error

SaveToDisk saves a given tx to the specified path.
