MetaTx Based Batched Transactions Example

MetaTx have proved to be an useful tool for quite a lot use cases. One of the main pain-points of the ERC-20 is the non-atomicity of the interaction with it. You can see how we've managed to make these transactions atomic through the use of MetaTx Proxy (sometimes called identity).

How to run it

npm install -g etherlime
etherlime ganache

npm install
npm start

Making sense of the code

The code is in the test folder. It does the following things:

1. Creates a BatchedMetaTx Proxy, ERC-20 and Consumer service contracts
2. Produces the artifacts needed for two transactions - approve and transferFrom-based call to the Consumer contract
3. Executing them at once atomically
4. Executing failing transaction reverting both of them
