- #Nix helped to setup a #echidna for our long running test over the weekend on a idle fresh mac mini machine. Super easy.
Last stretch before shipping GDA. #Security at #Superfluid
- Tested my first @erc4337.lens account https://github.com/p2p-org/eth-staking-fee-distributor-contracts/blob/master/contracts/feeDistributor/Erc4337Account.sol
Liked that my contract can now pay for its own gas.
A bit annoyed that during signature verification it's forbidden to do external calls.
- ITS FINALLY HERE
🎊🎉🎊🎉🎊🎉🎊🎉🎊🎉🎊🎉
The Ultimate, Learn Blockchain Development, Solidity, AI-Powered Smart Contract Course | Foundry Edition sponsored by @CyfrinAudits!
🎊🎉🎊🎉🎊🎉🎊🎉🎊🎉🎊🎉
Here is everything you'll learn from this course, and more 👇
You can find parts 1 - 3 (A new YouTube cap of 12 hours means I had to split it up!)
🔗 Here's a link to part 1 of the course, with parts 2 and 3 on my YouTube.
After 2+ months of pouring every ounce of information into a video, this is where we have arrived - with 27+ hours of pure KNOWLEDGE.

As many of you know, I've made a monster course every year for the past 3 years, dumping all my knowledge into a video so we can bring everyone in web3 up to speed quickly.
We chose Foundry this year because it is becoming the go-to tool for smart contracts and security researchers alike.
Here is a link to the entire course curriculum.

The best part of this year, is that since the course is in pure solidity, there are absolutely ZERO prerequisites, meaning anyone can take the course no matter where you are in your journey!
Additionally... We will teach you advanced AI prompting techniques so you can get up to speed FASTER THAN EVER BEFORE.
I can say with assurance that if you're looking to get started in Web3, Solidity, or become a blockchain developer, this is 100% the place to go.
I've poured my soul into this content, and we've been able to help thousands of developers in the past, with many developers surpassing me at their skill of smart contract development.
Here are some of the technologies, industries, and groups we will teach you:
- Solidity
- Foundry
- Chainlink
- MetaMask
- AlchemyPlatform
- EthereumRemix
- Openzeppelin
- trailofbits
- NFTs
- #Ganache

🔁 ❤️ Please smash this tweet a link and a retweet so we can bring web3 and blockchain to the masses by ushering the next generation of smart contract engineers.
And in case you missed it, here is the link to the video again.
Good luck, have fun, let's make the second half of this year for the builders & devs of the space.
Go Web3!!!!!

Part 2 is much more advanced and insightful than Part 1.
Especially I liked frontrunning and AttackLendly where everything came together in a beautiful multistage attack.
Thank you Johnny Time and the guests for sharing your great knowledge!
- How to Grow on Lens: Grow your Gang 0 to 20 🔥
Tip #2: Look for friends, not for followers 💪
Followers are usually passive. They look for what you publish and don't interact too much.
What you need to look for in your first gang of 20 is friends, people who like you, care about what you do and take their time to see your progress, life, and adventures.

- @JohnnyTime #SCH #frontrunning section is great!
This extremely important topic is often overlooked in #Solidity #security tutorials since frontrunning is not part of #EVM, rather a broader blockchain concept.
But you need to think about your every function being front run.

Pretty cool that uninitialized address (#oracle, owner, etc.) and invalid #signature recovery are both equal to 0, which makes them equal one to another, which makes the signature look valid.
