DeFi exploits?

[vanon]

I'm looking for someone who knows their way around Solidity and smart contracts.

There are various exploits, like uniswap re-entries, and others, that I'm curious as to if it's still possible to exploit (I can PM specifics). If not on uniswap, then on possible forks, like Sushi. Also, maybe on EVMs (Binance Chain & Smart Chain, Matic, Avalanche, etc), or other block chains, like Tron, Solana, etc.

Initially, a Q&A, so I can ask questions, and you can let me know if they're actually still possible, somewhere, or if they have been plugged.

I'd prefer a partnership to work on exploits and mixing tainted tokens, but realize most will prefer a professional-client relationship. Open to either.
