    Interface BatchSignableIdentity

    Identity that supports signing multiple PSBTs in a single wallet interaction. Browser wallet providers that support batch signing (e.g. Xverse, UniSat, OKX) should implement this interface to reduce the number of confirmation popups from N+1 to 1 during Arkade send transactions.

    Contract: implementations MUST return exactly one Transaction per request, in the same order as the input array. The SDK validates this at runtime and will throw if the lengths do not match.

    interface BatchSignableIdentity {
        compressedPublicKey(): Promise<Uint8Array<ArrayBufferLike>>;
        sign(tx: Transaction, inputIndexes?: number[]): Promise<Transaction>;
        signerSession(): SignerSession;
        signMessage(
            message: Uint8Array,
            signatureType: "schnorr" | "ecdsa",
        ): Promise<Uint8Array<ArrayBufferLike>>;
        signMultiple(requests: SignRequest[]): Promise<Transaction[]>;
        xOnlyPublicKey(): Promise<Uint8Array<ArrayBufferLike>>;
    }
