 Finthetix is a Staking Dapp heavily inspired by [Synthetix Stakng Rewards Contract](https://github.com/Synthetixio/synthetix/blob/develop/contracts/StakingRewards.sol). It uses Solidity (Foundry) for the Smart Contracts, and Remix-React and EthersJs for the web application. The web app is deployed on AWS Lambda and S3 (static assets), with AWS Cloudfront as the CDN. For more details, check out the [System Diagram](#system-diagram) below.

-Initially, I deployed this Smart Contract to [Sepolia Testnet](https://www.alchemy.com/overviews/sepolia-testnet). However the transactions were so slow, that I understood that realistically, noone would sit through this just to try out the Dapp. So I deployed it to [Polygon Mumbai Testnet](https://www.alchemy.com/overviews/mumbai-testnet). Gotta say, I'm super happy. The gas fees are really low, and the transactions are super quick. I hope the mainnet experience is the same!

I tried migrating to Amoy, but polygonscan doesn't support it yet, and I wanted to keep using `forge script`'s verify functionality. Cardona-zkEVM testnet was also considered, but it doesn't support EIP1559 yet (and foundry doesn't recognize the `--chain` name either).

+Finally I decided to go with Arbitrum Sepolia - native etherscan explorer, all the features of mainnet, nuff said.
 
 Deployments are done using Foundry's `forge script` tool. We source the secret keys from our cast wallet, for maximum security. [Thanks Patrick Collins!](https://www.youtube.com/watch?v=VQe7cIpaE54). The script itself is used as part of our Foundry tests, so we know it's legit.
