@elvisisvan You don't have to rebuild system deployment setup from scratch, which takes time and creates more surface for errors to be introduced in the process.

A cool hack for testing Hardhat projects with Foundry https://t.co/mCH6y4Q4qB

TLDR:
1. Choose a state you want to start with from current tests (or deployments)
2. Run a local Hardhat node
3. Run test on localhost network
4. Fork localhost in Foundry at current block
5. Test😉

@0xjmaria Ran into same problem with same solution @krakovia_evm mentioned.

If you run into this on Optimism, it has an on-chain gas oracle you can hit in the command line:

cast call 0x420000000000000000000000000000000000000F "gasPrice()"

It's always a great experience working with you 😉

Good luck on @parifinance 💪🚀

[lopotras @lopotras]

@TheBlockChainer Can imagine!
The effects are amazing though 😉

[lopotras @lopotras]

@KrisApost1 @zksync Can you recommend a resource which goes deeper into potential consequences?

I noticed something similar with impact of potential compiler bug fixes on deployed contracts on zkSync Era and would love to understand it better.

[lopotras @lopotras]

@Kodak_Rome Thanks for the kind words 🙌
Happy to provide, will do my best 💪

🔥 Get a FREE medium severity finding on ANY @code4rena or @sherlockdefi contest using Chainlink on L2!

This vulnerability stems from the potential for the sequencer to go offline, which could result in outdated and stale oracle data. 🧵

According to @DefiLlama, the 3 most forked protocols by TVL are:

1. Uniswap V2
2. Compound
3. AAVE

Studying them in depth will help every auditor to understand the most fundamental concepts of DeFi and save them a lot of time when they audit a fork of them. Some resource: 👇🧵

[lopotras @lopotras]

@devScrooge @TheBlockChainer And I feel like usually there probably is 😅
