-# Sample Hardhat Project
+# Atomic Swap
 
-This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, and a script that deploys that contract.
+This project implements HTLC based atomic swap between Ontology and Ethereum with an on chain bidding on the Ethereum chain.
 
-Try running some of the following tasks:
+Currently swap can be done only when order is initiated via Ontology and responded via Ethereum.
 
-```shell
-npx hardhat help
-npx hardhat test
-REPORT_GAS=true npx hardhat test
-npx hardhat node
-npx hardhat run scripts/deploy.js
-```
+Stack used:
+NodeJS: For creating a javascript environment that works as server
+Express: For routing
+MetaMask: Signing transactions
+Hardhat : Compiling and deploying smart contracts
+MongoDB Atlas: For storing the current bids in progress.

+Languages used:
+Solidity
+Javascript
