+# Ink! Awesome DeFi
+
+
+This is a Repo of Notable Smart contracts re-writen in Ink! domain (pallet-smart-contract) specific lanaguage. it outlines how production worthy smart contract should be built and structured. Smart contracts within this repo utilizes the awesome [Openbrush](https://openbrush.brushfam.io/) library of smart contract and utilities. This repo contains;
+
+1. Uniswap V2 Ink! Implementation.
+2. Synthetix staking reward contract
+3. Uniswap V3 still in the works (it complicated math libs got me lazy. Ticks 😒)
+
+
+My hopes for this Repo is for it to be a good resource for engineers/teams looking to build production worth smart contracts and wish other awesome developers would build into this repo other more complicated smart contracts making this Repo more useful to a wider range of teams in the polkaDeFI space.
+
+
+## Want to contribute?
+My buddy [Ayo](https://github.com/Adebara123), built a [template](https://github.com/Adebara123/Ink-Contract-Template) which I used to build these smart contracts and I would be employing you contributor to use that also.
