Useful Smart Contracts

This repository contains examples of tested gas efficient smart contracts, demonstrating best practices and basic ideas to implement DApps.

Samples

'DAOs' directory has sample quadratic DAO mechanism with explainations
'Proxy Contracts' can be used to deploy any smart contract, and execute its functions, dynamically.
'MultiSigWallet' is simple example where multiple owners need to approve transaction, before execution
'DutchAuction' is where price of the nft decreases by time, to a certain limit
'EnglishAuction' is where bidder increases price of the nft/asset, to win bid
'AccessControl' is where you want to define custom roles in your smart contract
'Kill' shows example of deleting smart contract. Surprised? :)
'HTLC (Hash TimeLocked Contract)' can swap cross chain tokens via atomic swap

I tried to use best practices in these examples. More examples are on the way :)
