Today, at @ContractReader, we're excited to launch Smart Contract Reviews powered by @openai's GPT-4.
Get a near-instant code review of mainnet or testnet smart contract!
This is in beta but it was too cool and useful not to ship. We'll continue to improve it over time.

I wrote an NPM package called @oxdoublesharp/unsafe-math that does unchecked math for #Solidity 0.8+ with user defined type operator overloads for Solidity 0.8.19. 🧮
Save gas with unchecked math where it won't under/overflow. ⛽️
Examples in the README.

Not enough hours in the day lately but I have some $FTM to give away* to happy shadow coders on #Fantom via @CaptureTheFunds soon! Today?
* if you can hack it 🕵️

#Echidna is a smart contract CLI #fuzzing tool from @trailofbits powered by #Slither and written in Haskell.
It works with #Solidity smart contracts and allows you to define and test invariants for your contracts against a large set of random inputs.

On-chain metadata #FNFT's like @Uniswap V3, @RevestFinance Resonate, @ByteMasons Reliquary, & @VelodromeFi.
Games like @lootproject & #Rarity on #Fantom.
These on-chain #NFT collectibles are for a @CaptureTheFunds #CTF and have attribute & color variations + special animations.

Exploits will be intentionally placed into the code for developers to find. Once it has been discovered @0xDoubleSharp will go over the vulnerability and how to hack it.
⛳️Capture The Funds #CTF
⌨️Primary goal is to capture funds found on the target contract. The format is open: if you find a vulnerability, exploit it.
⚠️You may be required to deposit funds & these funds may become lost to you forever. Proceed at your own risk.

⛳️#CTF tips:
🔔Hints and notification of contract addresses.
🎓Solidity knowledge is required. Bonuses provided for novel exploits, even after contract has been hacked.
🎥A walkthrough of a working exploit will be provided by @0xDoubleSharp.
🎟️Digital collectibles?
🎇Fun!
⛳️@CaptureTheFunds is deploying first on the #Fantom Opera network by @FantomFDN. Our #CaptureTheFlag prizes are the tokens stored on the contracts.
🎓Help educate others on #web3 #security best practices.

Congratulations #Fantom fans! 🥂
@CaptureTheFunds will deploy our first #CTF on the @FantomFDN Opera blockchain! 👻
Fantom won an impressive 83.5% of the vote! 🦾
Have mainnet $FTM ready in your wallet to cover gas fees for contract deployments & interactions. 🔷
