🧵 Mitigating Sandwich Attacks with @jito_labs
How It Works:
To prevent sandwich attacks in your Solana transaction, include any valid Solana public key starting with jitodontfront in one of the instructions.
Examples of such keys:
jitodontfront111111111111111111111111111111,
jitodontfront111111111111111111111111111123

the solana MEV landscape is evolving rapidly and the MEV tip market is far larger than most people realize
jito still leads the pack, but nextblock, temporal, and zeroslot are all vying for a bigger slice of the pie.
weekly averages:
@jito_labs: ~46,300 SOL/week (76% market share)
@0slot_trade: ~5,900 SOL/week (9.7%)
@temporal_xyz: ~4,400 SOL/week (7.2%)
@bloxroute: ~3,100 SOL/week (5.1%)
@nextblock_sol: ~1,200 SOL/week (2.0%)
~61K SOL/~11M USD per week just in tips for fast transaction inclusion — absolutely insane.

🧵Tips for Engineering Velocity
1. Commit early, commit often — but squash before merge.
2.) Prefer many small PRs over large ones. Large PRs are where good code goes to die.
3.) Tag reviewers when you start working, not when you're done. The goal is to fail fast and cheap.
4.) Test the happy path first, edge cases second
5.) Don’t wait to ask for help — blockers kill velocity.

You can effectively prevent sandwiching by including a vote account in the list of accounts.

🧵Reversible delayed swap:
it's like timeswap (which used xyz=k with time as a factor) but made perpetual by integrating it with the standard xy=k invariant.
Eg: Let's say ETH is $2000:
1.) You enter the position:
- Deposit 1 ETH ($4300 collateral)
- Borrow 1000 USDC
- You effectively have the "option" to buy back your ETH for 1000 USDC + interest
2.) Over time:
- You pay interest (like paying to keep an option alive)
- ETH price moves around
- You can "exercise your option" anytime by repaying 1000 USDC + interest
3.) If liquidated:
- The system automatically "exercises" by selling your.
- ETH through the AMM curve
- This respects xy=k, so it's like completing the delayed swap
---
realization:
1.) You do a swap (ETH → USDC) but don't complete it immediately
2.) You pay "interest" to keep this swap "on hold"
3.) You can either:
- Reverse the swap by paying back (get your ETH back)
- Let the swap execute via liquidation
----
the Innovation (bridges multiple worlds):
- Perpetual futures (no expiry, continuous funding)
- Options (right but not obligation, can exercise anytime)
- AMMs (settlement through xy=k curve)

🧵Ghost market makers are dominating Solana’s on-chain markets.
Out of $709.6M in SOL-USDC volume:
• SolFI alone did $448M
• ZeroFi did $97M
• All DEXs combined (OpenBook v2, Jupiter Perps, Lifinity, Orca) — just $183M
What’s the most plausible theory behind this?

We take security very seriously and have confirmed that Asgard was not impacted.
🚨 There’s a large-scale supply chain attack in progress: the NPM account of a reputable developer has been compromised. The affected packages have already been downloaded over 1 billion times, meaning the entire JavaScript ecosystem may be at risk.
The malicious payload works by silently swapping crypto addresses on the fly to steal funds.
If you use a hardware wallet, pay attention to every transaction before signing and you're safe.
If you don’t use a hardware wallet, refrain from making any on-chain transactions for now.
It’s still unclear whether the attacker is also stealing seeds from software wallets directly at this stage.
Excellent report here: jdstaerk.substack.com/p/we-j…

reversible delayed swap is here @solana
Explaining how @omnipair liquidation works, I realized it’s basically a “reversible delayed swap”:
you pay interest (fees) to hold the option to either reverse the swap by repaying debt + redeeming collateral, or let liquidation execute the swap.
(Impact-based dynamic CF ensures the xy=k invariant is respected in that kind of swap as well).

The key insight: don't build for crypto natives, build the bridge that brings traditional business into the programmable money world.
The companies that win will be those that make the transition invisible.

anon you are underestimating the potential of @asgardfi
God mode for money markets 🥩.
Was absolutely mindblown seeing the 1000 strong attendance at the Hacker house. Lots of young kids eager to learn and make their mark in the space, and all of them chose Solana as their entry point. @superteam does a great job in bringing the talent onboard and ensuring a bright future for Solana developer ecosystem.
Congrats to teams @asgardfi, @this_is_samridh (WalletSense) and @AtomWeb3 for being the first recipients of ChadGrants1.0. You guys have good products and put up impressive demos for the demo day. All the best.
Going to be more actively involved in the Solana eco at earliest stages as possible.
