This method uses Ethereum’s personal_sign
RPC method. If you are looking for a low-level raw signature over a input hash, see secp256k1_sign.
Use the signMessage
method exported from the useSignMessage
hook to sign a message with an Ethereum embedded wallet.
Message to be signed.
The signature produced by the wallet.
Configure callbacks for Privy’s signMessage
method on the useSignMessage
hook:
As parameters to useSignMessage
, you may include an onSuccess
callback and/or an onError
callback.
While this component is mounted, any invocation of signMessage
will trigger the onSuccess
callback or onError
callback on completion, depending on if the message was successfully signed or not.
If set, the onSuccess
callback will execute after a user has successfully signed the message. Within this callback, you can access a signature
parameter, which is the signature
string value generated by the wallet to sign the message.
If set, the onError
callback will execute after a user attempts to sign a message and there is an error, or if the user exits the signature flow prematurely. Within this callback, you may access an error
code with more information about the error.
