Alternative Signers

Learn how Uniswap smart wallet supports alternative signer keys and related security caveats.

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

Supported Key Types

  • Secp256k1
  • Secp256r1 (P256)
  • WebAuthn P256

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!
