Droplinked Solidity Contracts

This repository contains the droplinked's smart-contract source code for EVM chains that droplinked integrates with, including : Polygon, Binance, Hedera and Ripple sidechain

Run tests

To run the tests on the contract you can run the following command

npx hardhat test test/test.ts

Deploy

To deploy the contract to a network, follow these steps:

1. Add your network to the hardhat.config.ts file, by simply looking at the exapmles that are there
2. Put your etherscan api key in the etherscan part
3. Run the following command to deploy :

npx hardhat run scripts/deploy.ts --network $network_name_here$

For instance, running

npx hardhat run scripts/deploy.ts --network polygon_mumbai

would result in something like this

Contracts

You can find the contract source codes for 2 types of chains in the Contracts folder,

• DrpPayment.sol file contains the payment contract source code
• DrpPolygon.sol file contains the Droplinked-contract source code for chains which ChainLink has price feeds on them which are : Polygon & Binance
• DrpPolygonSg.sol file contains the Droplinked-contract source code for chains which ChainLink doen't have price feeds on them, It relies on price signing and signature verification for payments
