Firefly V3

This repository contains the core smart contracts for the Firefly V3 Protocol. For higher level contracts, see the firefly-v3-periphery repository.

Bug bounty

This repository is subject to the Firefly V3 bug bounty program, per the terms defined here.

Local deployment

In order to deploy this code to a local testnet, you should install the npm package @firefly-dex/core-v3 and import the factory bytecode located at @firefly-dex/core-v3/artifacts/contracts/FireflyV3Factory.sol/FireflyV3Factory.json. For example:

import {
  abi as FACTORY_ABI,
  bytecode as FACTORY_BYTECODE,
} from '@firefly-dex/core-v3/artifacts/contracts/FireflyV3Factory.sol/FireflyV3Factory.json'

// deploy the bytecode

This will ensure that you are testing against the same bytecode that is deployed to mainnet and public testnets, and all Firefly code will correctly interoperate with your local deployment.

Using solidity interfaces

The Firefly v3 interfaces are available for import into solidity smart contracts via the npm artifact @firefly-dex/core-v3, e.g.:

import '@firefly-dex/core-v3/contracts/interfaces/IFireflyV3Pool.sol';

contract MyContract {
  IFireflyV3Pool pool;

  function doSomethingWithPool() {
    // pool.swap(...);
  }
}
