+# Minimal Swap PoC
+
+A minimal end to end proof of concept of using Swap contracts written by Swarm and maintained here: https://github.com/ethersphere/swap-swear-and-swindle
+
+All contract code imported from the above repo.
+
+Ported to Hardhat and Ethers.io.
+
+
+# How to run
+
+For scripts there is a script to setup SWAP contracts. To run it and make it persistent we can do the following:
+
+``` sh
+# Run a node
+npx hardhat node
+
+# Run script to setup SWAP contracts
+npx hardhat run scripts/setup-swap.js
+```
+
+Which will return you a list a list of addresses for ERC20, Alice, Bob, and their respective SWAP contracts.
