Methods

bcsToBytes

bcsToBytes(): Uint8Array
Serializes a Serializable value to its BCS representation. This function is the Typescript SDK equivalent of bcs::to_bytes in Move.

Returns Uint8Array
the BCS representation of the Serializable instance as a byte buffer
Inherited from Signature.bcsToBytes
- Defined in src/bcs/serializer.ts:27

bcsToHex

bcsToHex(): Hex
Helper function to get a value's BCS-serialized bytes as a Hex instance.

Returns Hex
a Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array
Inherited from Signature.bcsToHex
- Defined in src/bcs/serializer.ts:37

isCanonicalSignature

isCanonicalSignature(): boolean
Checks if an ED25519 signature is non-canonical.

Comes from Aptos Core https://github.com/aptos-labs/aptos-core/blob/main/crates/aptos-crypto/src/ed25519/ed25519_sigs.rs#L47-L85

Returns boolean
- Defined in src/core/crypto/ed25519.ts:334

serialize

serialize(serializer): void
Parameters
- serializer: Serializer
Returns void
Overrides Signature.serialize
- Defined in src/core/crypto/ed25519.ts:319

toString

toString(): string
Get the signature as a hex string with a 0x prefix e.g. 0x123456...

Returns string
Inherited from Signature.toString
- Defined in src/core/crypto/signature.ts:20

toUint8Array

toUint8Array(): Uint8Array
Get the raw signature bytes

Returns Uint8Array
Overrides Signature.toUint8Array
- Defined in src/core/crypto/ed25519.ts:311

`Static` deserialize

deserialize(deserializer): Ed25519Signature
Parameters
- deserializer: Deserializer
Returns Ed25519Signature
- Defined in src/core/crypto/ed25519.ts:323
