We’ve created the step-by-step guide for the Rainbow Bridge + ERC20-NEP21 connector.
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.
We highly encourage sharing your feedback, submitting PRs and issues.
