SignatureEnvelope

Signature envelope utilities for secp256k1, P256, WebAuthn, and keychain signatures.

Tempo transactions support multiple signature types: secp256k1 (65 bytes), P256 for passkeys (type 0x01), WebAuthn (type 0x02), and Keychain for access keys (type 0x03).

Signature Types Specification

Examples

import { Secp256k1 } from 'ox'
import { SignatureEnvelope } from 'ox/tempo'
 
const privateKey = Secp256k1.randomPrivateKey()
const signature = Secp256k1.sign({ payload: '0xdeadbeef', privateKey })
 
const envelope = SignatureEnvelope.from(signature)

Functions

Name	Description
`SignatureEnvelope.assert`	Asserts that a `SignatureEnvelope.SignatureEnvelope` is valid.
`SignatureEnvelope.deserialize`	Deserializes a hex-encoded signature envelope into a typed signature object.
`SignatureEnvelope.extractAddress`	Extracts the address of the signer from a `SignatureEnvelope.SignatureEnvelope`.
`SignatureEnvelope.extractPublicKey`	Extracts the public key of the signer from a `SignatureEnvelope.SignatureEnvelope`.
`SignatureEnvelope.from`	Coerces a value to a signature envelope.
`SignatureEnvelope.fromRpc`	Converts an RPC-formatted signature envelope to a typed signature envelope.
`SignatureEnvelope.getType`	Determines the signature type of an envelope.
`SignatureEnvelope.serialize`	Serializes a signature envelope to a hex-encoded string.
`SignatureEnvelope.sortMultisigApprovals`	Orders native multisig owner approvals into the strictly-ascending recovered-owner order the Tempo node requires for the multisig `signatures` array (the node enforces "recovered owners must be strictly ascending").
`SignatureEnvelope.toRpc`	Converts a signature envelope to RPC format.
`SignatureEnvelope.validate`	Validates a signature envelope. Returns `true` if the envelope is valid, `false` otherwise.
`SignatureEnvelope.verify`	Verifies a signature envelope against a digest/payload.

Errors

Name	Description
`SignatureEnvelope.CoercionError`	Error thrown when a signature envelope cannot be coerced to a valid type.
`SignatureEnvelope.InvalidSerializedError`	Error thrown when a serialized signature envelope cannot be deserialized.
`SignatureEnvelope.MissingPropertiesError`	Error thrown when a signature envelope is missing required properties.
`SignatureEnvelope.VerificationError`	Error thrown when a signature envelope fails to verify.

Types

Name	Description
`SignatureEnvelope.GetType`	Statically determines the signature type of an envelope at compile time.
`SignatureEnvelope.Keychain`
`SignatureEnvelope.KeychainRpc`
`SignatureEnvelope.KeychainVersion`	Keychain signature version.
`SignatureEnvelope.Multisig`	Native multisig signature (type `0x05`).
`SignatureEnvelope.MultisigRpc`
`SignatureEnvelope.P256`
`SignatureEnvelope.P256Rpc`
`SignatureEnvelope.Secp256k1`
`SignatureEnvelope.Secp256k1Flat`

`SignatureEnvelope.Serialized`	Hex-encoded serialized signature envelope.
`SignatureEnvelope.SignatureEnvelope`	Represents a signature envelope that can contain different signature types.
`SignatureEnvelope.SignatureEnvelopeRpc`	RPC-formatted signature envelope.
`SignatureEnvelope.Type`	Union type of supported signature types.
`SignatureEnvelope.WebAuthn`
`SignatureEnvelope.WebAuthnRpc`
