SignatureEnvelope Types

`SignatureEnvelope.Attested`

Attested signature (type 0x06).

A program key, held by attested code and registered in the Attested Key Registry, signs AttestedSigner.getSignPayload of the context digest for the address AttestedSigner.getAddress derives from policyId and userTag. The node also checks that the registry holds the program key as current in slot and that validUntil is within AttestedSigner.maxValidityWindow seconds of the block timestamp.

TIP-1160

`SignatureEnvelope.AttestedRpc`

RPC-formatted attested signature, as the node serializes it (untagged).

Source: src/tempo/SignatureEnvelope.ts

`SignatureEnvelope.Configurable`

Configurable account signature (type 0x05).

Carries the account's complete current configuration and primitive owner approvals over its version-bound digest. The node validates the account identity or stored commitment and the owner quorum against chain state.

Source: src/tempo/SignatureEnvelope.ts

`SignatureEnvelope.ConfigurableRpc`

RLP-encoded [account, config, signatures], without the 0x05 type byte.

Source: src/tempo/SignatureEnvelope.ts

`SignatureEnvelope.GetType`

Statically determines the signature type of an envelope at compile time.

Examples

import type { SignatureEnvelope } from 'ox/tempo'
 
type Type = SignatureEnvelope.GetType<{ r: bigint; s: bigint; yParity: number }>
'secp256k1'

`SignatureEnvelope.Keychain`

Source: src/tempo/SignatureEnvelope.ts

`SignatureEnvelope.KeychainRpc`

Source: src/tempo/SignatureEnvelope.ts

`SignatureEnvelope.KeychainVersion`

Keychain signature version.

'v1': Legacy format. Inner signature signs the raw sig_hash directly. Deprecated at T1C. - 'v2': Inner signature signs keccak256(sig_hash || user_address), binding the signature to the specific user account.

`SignatureEnvelope.OwnerApproval`

Signature envelope that can approve as a configurable account owner: a primitive signature, or an attested signature.

`SignatureEnvelope.OwnerApprovalRpc`

RPC-formatted signature envelope that can approve as a configurable account owner.

`SignatureEnvelope.Primitive`

Primitive signature envelope accepted by protocol sidecars.

`SignatureEnvelope.PrimitiveRpc`

`SignatureEnvelope.Secp256k1Flat`

`SignatureEnvelope.Secp256k1Rpc`

`SignatureEnvelope.Serialized`

Hex-encoded serialized signature envelope.

`SignatureEnvelope.SignatureEnvelope`

Represents a signature envelope that can contain different signature types.

Tempo transactions support multiple signature types, each with different wire formats:

secp256k1 (no type prefix, 65 bytes): Standard Ethereum ECDSA signature. The sender address is recovered via ecrecover. Base transaction cost: 21,000 gas.
p256 (type 0x01, 130 bytes): P256/secp256r1 curve signature for passkey accounts. Includes embedded public key (64 bytes) and prehash flag. Enables native WebCrypto key support. Additional gas cost: +5,000 gas over secp256k1.
webAuthn (type 0x02, 129-2049 bytes): WebAuthn signature with authenticator data and clientDataJSON. Enables browser passkey authentication. The signature is also charged as calldata (16 gas/non-zero byte, 4 gas/zero byte).
keychain (type 0x03 V1, 0x04 V2): Access key signature that wraps an inner signature (secp256k1, p256, or webAuthn). Format: type byte + user_address (20 bytes) + inner signature. V2 binds the signature to the user account via keccak256(sigHash || userAddress). The protocol validates the access key authorization via the AccountKeychain precompile.
configurable (type 0x05): Configurable account signature carrying the account address, its complete current configuration, and primitive owner approvals over the version-bound digest.
attested (type 0x06, experimental): Signature by a program key that the Attested Key Registry holds as current, for the address derived from a policy ID and a user tag (TIP-1160). Accepted as a transaction signature, a key authorization signature, and a configurable account owner approval. Rejected inside keychain signatures.
