Implementation of​

ITransactionSigner.sign

publicKey()​

publicKey(): Promise<PublicKey>

Get the public key for this signer.

Returns​

Promise<PublicKey>

The Ed25519 public key.

Implementation of​

ITransactionSigner.publicKey

iotaPublicKeyBytes()​

iotaPublicKeyBytes(): Promise<Uint8Array<ArrayBufferLike>>

Get the IOTA-formatted public key bytes (scheme flag byte followed by the raw key bytes).

Returns​

Promise<Uint8Array<ArrayBufferLike>>

The IOTA public key bytes.

Implementation of​

ITransactionSigner.iotaPublicKeyBytes

keyId()​

keyId(): string

Get the vault key name used by this signer.

Returns​

string

The key name.

Implementation of​
