ERC20ProxyForZRC2 Contract

NOTE this is an unedited fork from https://github.com/Zilliqa/zilliqa-developer/tree/c9a723dfdd0555b4876de83562c63950301d3ea6/contracts/experimental/ERC20ProxyForZRC2

This repo was created before zilliqa-developer existed. the zrc2 proxy is written by Zilliqa.

If you want to create ZRC2 proxies, fork the official one.

NOTE: if using windows, use WSL.

These contracts allow ZRC-2 tokens to look like ERC-20 tokens.

Unless you want to build using the zilliqa-developer version of zilliqa-js, or you encounter missing modules issues while running tests, install our dependencies with:

pnpm --ignore-workspace i
pnpm exec hardhat compile

Deploying a proxy

You can deploy a proxy with:

export PRIVATE_KEY=<...>
pnpm exec hardhat deployProxy 0x5DD38E64dA8f7d541d8aF45fe00bF37F6a2c6195 --network zq-testnet

If your ZRC-2 is burnable (ie. supports the Burn() transition), you can use:

export PRIVATE_KEY=<...>
pnpm exec hardhat deployProxyBurnable 0x5DD38E64dA8f7d541d8aF45fe00bF37F6a2c6195 --network zq-testnet

The task should automatically verify these contracts to sourcify.

Networks

Various networks are available in the hardhat.conf.ts:

• zq-testnet - the Zilliqa 1 testnet
• zq - the Zilliqa 1 mainnet
• local-proxy - a local proxy.

You can use the local-proxy network and run:

mitmweb --mode reverse:https://dev-api.zilliqa.com --no-web-open-browser --listen-port 5556 --web-port 5557

To monitor requests.

Testing

To run the tests:

export PRIVATE_KEY=<...>
export TEST_KEY_1=<...>
export TEST_KEY_2=<...>
pnpm exec hardhat test --network zq-testnet

Each test has a number prefix so you can select them individually.

If you set the CACHED environment variable, we will use:

• CACHED_ZRC2 - address of a ZRC-2
• CACHED_ERC20 - address of an ERC-20

To run the tests; this saves you having to redeploy each time.

This allows you to run tests quickly, without waiting for contract deployment.
