We’ve created the [step-by-step guide](https://github.com/djsatok/bridge-testing) for the Rainbow Bridge + ERC20-NEP21 connector.

 ![Screenshot 2021-02-07 at 23.39.08](https://europe1.discourse-cdn.com/flex005/uploads/gov_near/original/1X/6268600f3b1eb919494524765ef37b3b27adef77.png)

The guide demonstrates how to make use of the rainbow bridge from the CLI using `ethers.js` and `near-api-js`. This guide will be helpful for the developers that consider integration with the rainbow bridge and especially with the fungible token connector.

At the moment the guide has one major drawback. It works only with already deployed tokens on the NEAR side. This would be fixed with [adding a script for deploy new tokens](https://github.com/djsatok/bridge-testing/issues/1).

We highly encourage sharing your feedback, submitting PRs and issues.

**Update [2021-02-12]**: added withdrawals to the guide
