Alternative Signers

Bu açık kaynak protokol/SDK referansı TurkDex markasıyla sunulan uyarlamadır; sayfadaki entegrasyon örnekleri Turkchain’de etkin özelliklerin garantisi değildir. Ağ, kontrat ve işlem değerlerinde yalnızca bu kurulumun doğrulanmış ENV/registry bilgilerini kullanın.

Calibur allows users to add any number of signers to their account, known as keys.

Supported Key Types

• Secp256k1
• Secp256r1 (P256)
• WebAuthn P256

Key Encoding and Identity

Each key is identified by its type and its encoded public key, and every key maps to exactly one identifier. When you register a key, you must supply it in its exact canonical form:

• A Secp256k1 key must be exactly its 20-byte address, with no extra padding or trailing bytes.
• A Secp256r1 (P256) or WebAuthn P256 key must be exactly its two public-key coordinates, with no extra trailing bytes.

Registrations that include padding or trailing bytes are rejected with InvalidKey. Well-behaved libraries already encode keys this way. Requiring the canonical form guarantees a one-to-one mapping between a key and its identifier, so a key's settings such as expiry, hooks, or admin status cannot be sidestepped by registering a look-alike of the same underlying key.

Passkey Signatures and User Verification

When validating a WebAuthn P256 (passkey) signature, the wallet does not require the authenticator's User Verification (UV) flag. The UV flag indicates that the user was verified by biometric or PIN rather than by presence alone. A passkey signed with user presence only is still accepted.

If your integration needs stronger guarantees for sensitive actions, enforce the UV requirement in your own client or relayer before submitting. The contract does not reject a signature that lacks the UV flag.

Security Caveats

This is an advanced feature. Please be aware of the following:

• By default, added keys do not expire and have no hooks
• A malicious key could steal all of your ETH and tokens

Registering external signers on your account changes the security model. Proceed with caution!
