+# Atomic Swap
+
+This project implements HTLC based atomic swap between Ontology and Ethereum with an on chain bidding on the Ethereum chain.
+
+Currently swap can be done only when order is initiated via Ontology and responded via Ethereum.
+
+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   
+
+
+Deploy contracts using:  npx hardhat run --network sepolia scripts/deployeth.js and deployont.js for ontology_testnet
+
+1. npm install
+2. Setup metamask wallet
+3. Configure two networks in metamask:
+
+    ONTOLOGY TESTNET   
+    Network name - Ontology TestNet   
+    New RPC URL - https://polaris2.ont.io:10339    
+    Chain ID - 5851   
+    Currency symbol - ONT   
+    Block explorer URL(Optional) - https://explorer.ont.io/testnet   
+
+    GOERLI TESTNET    
+    Network name - Goerli test network   
+    New RPC URL - https://goerli.infura.io/v3/    
+    Chain ID - 5    
+    Currency symbol - GoerliETH   
+    Block explorer URL(Optional) - https://goerli.etherscan.io   
+
+4. Run npm app.js
+5. localhost:3000 -> For the platform
+6. localhost:3000/txns -> For the order book
