Swaplace

This repository contains the core smart contracts for the Swaplace Protocol; The lightest Swap protocol in the market.

TL;DR

• Contracts cannot be upgraded.
• Contracts have no ownership.
• Contracts don't charge fees.
• There are no external contract dependencies.
• The protocol operates using available allowances.

Incentives

This repository is subjected to incentives for the community to contribute to the project. The incentive distribution and amount are being discussed but the eligibility has already started.

Features

• Create Swaps: A Swap has an owner and an allowed address. The owner is the one that can cancel the swap while the allowed address is the one that can execute the swap but anyone can accept if it's set as the Zero Address. A Swap also has an expiry period in seconds. The Swap can only be executed before the expiry period is reached. The Asset type represents on one hand the bidding assets and on the other hand the asking assets.

    struct Swap {
        address owner;
        address allowed;
        uint256 expiry;
        Asset[] biding;
        Asset[] asking;
    }

• Accept Swaps: You can accept swaps that have an allowed address equal to your or the Zero Address. As long as you provide the asked assets.

• Cancel Swaps: You can cancel swaps that haven't been expired.

• Swap Factory: Aids new swap creations to be used on Swaplace. Check contracts/SwapFactory.sol.

Environment Variables

The project comes with a .env.example file. You should rename it to .env and fill the variables with your values. Most RPC providers offer free testnet nodes. You can use Alchemy or Infura to get a free node.

WARNING: The private keys used in the .env file are from hardhat accounts. They are not meant to be used in production.

Testing and Deploying

Run the tests in localhost or try the contracts in a desired network by specifying the network name in hardhat.config.js.

yarn test
yarn testnet <network>

Deploy the contracts in the desired network according to the networks available in hardhat.config.js.

yarn deploy <network>
