GSN Relay Server
GSN, the Ethereum Gas Station Network abstracts away gas to minimize onboarding & UX friction for dapps.
This module contains Relay Server source code. Note that it is recommended to use a Docker container opengsn/jsrelay to run your own Relay Servers.
You are probably looking for one of these:
@opengsn/provider - a Web3 provider for client-facing JavaScript dapps that uses GSN to relay transactions.
@opengsn/contracts - all GSN contracts in Solidity language as well as their TypeScript type declarations.
@opengsn/cli - command-line tools made to help developers integrate GSN, test their integrations locally, or bring up relay servers on public Ethereum networks.
