filecoin-js-signer

Filecoin signing library and RPC client in pure Typescript / Javascript with the necessary methods to create, sign and broadcast messages to send FIL, and interact with Filecoin's built-in actors (like Payment Channel and Multisig).

Motivation

This library was created as part of the Filecoin Loans Grant awarded by the Filecoin Foundation. At the time of its creation (April 2021), there were no functional signing libraries written in pure Javascript or that had a complete implementation of the Payment Channel actor's methods (i.e. passing a hash/secret to create and redeem vouchers, necessary to create Atomic Swaps / Atomic Loans). A pure Javascript implementation of these methods can also facilitate, or simplify, the usage from React Native or web applications that interact with the Filecoin network.

Installing

npm install --save @blitslabs/filecoin-js-signer
