Fantom FMint DeFi module

The repository implements fMint module of the Fantom DeFi smart contracts in Solidity based on Andre Cronje's implementation.

Please note we use OpenZeppelin library version 2.5 along with the Solidity 0.5 and truffle to conform with the EVM implemented in the Opera block chain. Consult the Truffle documents to find out how to build and deploy the smart contract implemented here.

In general, all you should need to do is to call truffle build to get the deployable contract code and ABI inside build/ folder.

Deployment Requirements

The Fantom fMint contract has following dependencies:

  • Wrapped FTM ERC20 contract wFTM.
  • At least one ERC20 token contract with minting and burning capability, see IERC20Detailed. We use OpenZeppelin implementation internally.
  • ChainLink compatible price oracle aggregates for each ERC20 token used, see AggregatorInterface.
  • Fantom Price Oracle Proxy Fantom Oracle PriceFeed.
  • Fantom DeFi Token Registry contract, available in this repository.
  • Fantom fMint Address Provider contract, available in this repository.
  • Fantom fMint Reward Distribution contract, available in this repository.

Price oracle aggregates must receive price feeds from trusted external sources. Tokens will be rejected without a price tag even if they are registered in the token registry to be used with the fMint.

Deployment using Lachesis JavaScript Console

We assume you have the deployment account unlocked using personal.unlockAccount() call and you have the account address stored in account variable.

var account = "0x11111111111111111111111111111111";
personal.unlockAccount(account, "very-secret-password", 300);
web3.ftm.defaultAccount = account;

Deployment Steps

  1. Deploy wFTM and ERC20 tokens you will be using with the fMint.

  2. Deploy ChainLink compatible Price Oracle Aggregates.

  3. Deploy Fantom Price Oracle Proxy contract.

var oracleUSD = "0x8019db8a3ff1887d047f2dc1c7265ea8dab1ca80";

// assign the oracles to tokens
priceProxy.setAggregator(tokenWFTM, oracleFTM);
priceProxy.setAggregator(tokenUSD, oracleUSD);

  5. Deploy Token Registry from this repository.
