Tapioca harnessing LayerZero omni-chain infrastructure 🤯

• TapiocaWrapper Handle the deployment of TOFT contracts and execution of its onlyOwner functions.
• TapiocaOFT OFT20, Layer-Zero superset of ERC20. Handles the wrap and unwrap of a desired ERC20.

Note: Current tasks/contracts are designed so that a TOFT works best on a support LZ chain and Optimism only

Repo setup

1. Fill in .env
2. git submodule update --init

Flow of deployment

1. Deploy the TapiocaWrapper contract on the host chain of the ERC20, and the chain where you want it to be present too.

npx hardhat deploy --network '...'

2. Whitelist the ERC20 that you want to support in constants
3. Deploy the TapiocaOFT contract on the host chain .

$ npx hardhat deployTOFT --erc20 '...' --lzChainId '...' --network '...'

4. Repeat the process above and deploy it on any other chain you want it to be present.

Individual operations

Deploy a TOFT

Deploy a TOFT contract to the specified network. It'll also deploy it to Tapioca host chain (Optimism, chainID 10). A document will be created in the deployments.json file.

• erc20: The address of the ERC20 to be wrapped.
• lzChainId: The Layer-Zero chain ID of the host chain.
• network: The network (must be the host chain).

$ npx hardhat deployTOFT --erc20 '...' --lzChainId '...' --network '...'

List TOFTs

List the deployments of a TapiocaWrapper given a network.

• network: The network (must be the host chain).

$ npx hardhat listDeploy --network '...'

Wrap an ERC20

Wrap an ERC20 into a TOFT.

• toft: The address of the toft.
• amount: The amount of ERC20 to wrap in wei.
• network: The network (must be the host chain).

$ npx hardhat wrap --toft '...' --amount '...' --network '...'

Send a TOFT

Transfer a TOFT amount between chains.

• toft: The address of the toft.
• to: The address to send to.
• amount: The amount of ERC20 to wrap in wei.
• network: The network (must be the host chain). It'll automatically pick the other chain from deployments.json.

$ npx hardhat sendFrom --toft '...' --to '...' --amount '...' --network '...'
