Sign Messages

Bitte Wallet provides functionalities for signing and verifying messages. This documentation outlines the steps for using these features, including signing a message, verifying a message via the UI.

Sign Message

The sign message functionality allows you to sign a message using your Mintbase Wallet. The signed message can then be used for various verification purposes.

Endpoint

• URL: https://wallet.bitte.ai/sign-message

Parameters

• message: The message you want to sign.

• callbackUrl: The URL to which the signed message will be sent.

• nonce: A unique identifier to prevent replay attacks.

Example

https://wallet.bitte.ai/sign-message?message=hey&callbackUrl=https://wallet.bitte.ai&nonce=1

Always make sure to encode the parameters when redirecting

message=${encodeURIComponent}&callbackUrl......

You can generate the nonce using this code snippet

const nonce = Buffer.from(randomBytes(32)).toString('base64')

Verify Message

The verify message functionality allows you to verify a signed message using the UI or API. Verification ensures that the message was signed by the rightful owner of the specified account.
