Variable SignerCapability`Const`

SignerCapability: {
    EcdsaSign: number;
    EcdsaVerify: number;
    HdDerivation: number;
    PrivateKeyExport: number;
    PublicKeyTweak: number;
    SchnorrSign: number;
    SchnorrVerify: number;
} = ...

Bitfield flags describing the cryptographic operations an ECPairSigner can perform.

Combine with bitwise OR (|) and test with bitwise AND (&).

Type Declaration

ReadonlyEcdsaSign: number
Can produce ECDSA signatures (requires a private key).
ReadonlyEcdsaVerify: number
Can verify ECDSA signatures.
ReadonlyHdDerivation: number
Supports BIP-32 hierarchical deterministic derivation.
ReadonlyPrivateKeyExport: number
Can export the raw private key bytes.
ReadonlyPublicKeyTweak: number
Can derive a tweaked child key via Taproot-style tweaking.
ReadonlySchnorrSign: number
Can produce BIP-340 Schnorr signatures (requires a private key and backend support).
ReadonlySchnorrVerify: number
Can verify BIP-340 Schnorr signatures (requires backend support).

Example

const caps = signer.capabilities;
if (caps & SignerCapability.SchnorrSign) {
    // Schnorr signing is available
}
