You might have heard about "Prop AMMs" on Solana. We built a lightweight dashboard:. - streams realtime data from 2 Prop AMMs.- plots continuous-depth curves => can see sub 1 bps.- cross-pool router simulator => can see sub 0.5 bps

New weekly Claude Code limits dropped. They sent out 3 variations of the email depending on which plan you have so summarized them here. Based on this, Max 20x isn't really 4x the Max 5x plan

One interesting thing about GoonFi that I haven't seen anyone mention (or discover?). GoonFi uses both whitelist and blacklist controls, something most Solana programs don't. * Whitelist: Only accepts calls from Jupiter v6.* Blacklist: seeing 246 traders already flagged. An.
1000 *genuine* likes and I tell the world who GoonFi and HumidiFi are! . Gobble Gobble.

If you don't believe in wide(*) sandwiching, here's a thought experiment:. Let's assume a MEV bot:. (1) Has access to a transaction, with or without the signature. (2) Does _not_ have privileged access to the current leader _and_ cannot bundle through Jito. So you're either
I am highly skeptical of "blind sandwiching". It seems far more plausible that "blind" sandwiching is simply validators sandwiching and trying to avoid being caught.

This might be controversial, but your transactions should be able to fight back against malicious sandwiching validators. I built a simple program to do exactly that. You can't know at runtime if slippage is natural market movement or a sandwich attack. But if your swap lands

Skimmed 10 "comprehensive" and "in-depth" guides about eip-7702. Not a single one had an example on how to actually build a 7702 transaction. The only one I found was in the alloy examples repo. Take a look:

Good time as any for my yearly reminder that 550,000 ETH is still locked away forever in original Parity multisig wallets. If there's a vulnerability in Gnosis Safe or other smart contract-based wallets, it would be foolish to expect a chain fork.
What makes people comfortable storing large $ in Gnosis Safe? . What would it take to replicate that in another smart contract that acts as a user wallet?.

Cool use of litesvm to simulate SolFi swaps.
Nearly 25% of atomic arbs (and 13% of rev) on Solana touch a SolFi pool. I was curious how SolFi works. When something is closed source and with no IDL sometimes the best thing to do is to simulate. Over the weekend, my co-founder wrote a simple simulator that fetches all pool

Even better, use a Dutch auction. Bonding curves still rely on a party (not the market) trying to 'solve' price discovery at the wrong level—tweaking constants or formulas isn’t the answer. Let the market decide the price, not a fixed curve. *then* switch to an AMM.
creating a steeper bonding curve is a way to solve this problem. It should be EV- to snipe every launch or it will continue to happen. Doppler-v3 utilizes a programmable bonding curve that controls the steepness of the curve by adjusting 1 parameter.

onchain thinking machines (whether they use a TEE or not is an implementation detail) are the only way under-collateralized loans will ever work in crypto. an AI agent with a verifiable brain can be perfectly risk-scored, creating trustless, scalable credit systems.

Once again, impressive work by the fuzzland (now: solayer) team. Within 5min of the hacker's implementation contract being deployed, they were able to detect the vulnerability and bridge over funds to initiate a rescue. Building and submitting the rescue txn itself seems to.
We just automatically hacked the hacker and rescued 1.4M USDC!. 100% of fund were returned to the project owner. > 🧵 Here's how the hacker is whitehat-hacked

Remember Chi gas tokens?. The original gas arbitrage. You could mint or buy them when gas was cheap and then use them when gas was expensive. Burning Chi gas tokens in a transaction would refund gas, up to 50% of the total gas usage.
