@covalenthq/js-sign v1.0.22

js-sign ·

js-sign library allows browsers and Node.js clients to create signature payload in order to interact with Covalent API. Generally, only one function call is required to create the necessary signature.

Currently, when using some Covalent API endpoints, the only data that required signing is the wallet address.
