Sui is cutting gas again today. Trading on @AftermathFi now costs makers and takers about 80% of what it did two weeks ago.
Quick update on where we are 👇
Aftermath Perps is fully onchain. No sequencer, no off-chain matching engine, no maker getting first look. Every order is matched and settled by Sui's 100+ validators.
Why that matters:
- You can verify the rules of the venue instead of trusting them
- One tx can open positions across markets with PTBs
- No single operator can halt, reorder or front-run your trade
- The contracts keep running no matter what happens to any one at AF
The numbers, through a rough stretch:
- >15% of all @SuiNetwork activity
- ~$8M daily volume
- $1M+ open interest
- ~40% APR with afLP TVL up 2x in two weeks, and outperforming the market
Unique markets that are hard to find anywhere else like: NIFTY, BAT, BP, PRL, with more coming.
We literally have NO MM deals. No private liquidity deals. Every reward we get goes to traders and anyone running their own MM bot. It's open to everyone.
Easier to start than ever:
- One click trading enabled automatically for new users with our new UI flow
- Public API aftermath.finance/api/openap… an MCP & Skills for agents mcp.aftermath.finance/mcp
- Live on @tread_fi, more integrations soon
Aftermath is not a fork of anything. We've been building this since 2022, and with Mysten focusing on trading and helping us with gas we're shipping faster than ever.

Step one of cheaper fully onchain trading is live on @SuiNetwork.
This upgrade cuts non-refundable storage fees by 99%. We estimate a 60–70% reduction in total gas for quoting txs, making it cheaper for market makers to place, cancel and update orders on Aftermath Perps.
Lower costs make tighter spreads and deeper liquidity more economical. These are meaningful improvements for a fully onchain orderbook.
Big thanks to @mystenmark and the Sui team.

Weekly update. Two recoveries.
@AftermathFi bounced back after last week's drop. TVL went from 1.9M back to 4.7M in three days. 7d APR turned positive at +18% (was -26% last week). Only two weeks in the tracker and already through one full cycle.
@Lighter_xyz keeps climbing. 7d APR went from 5% to 31% this week. TVL steadily growing (73M -> 79M). 30d APR recovering too, back to 11% after last week's dip to 8%.
Elsewhere in the tracker:
- @paradex : 7d APR bottomed at -49% mid-week, back to -10% now. Still negative but the direction changed. TVL below 3M for the first time
- @Aster_DEX : back on the swings, +136% to -43% in a week
- @Backpack : 7d APR climbed back to 27%, 30d holding at 20%
- @Ostium : two months since the promised recovery plan, LPs still waiting

Full report below.

Aftermath Postmortem
On April 29th, Aftermath experienced an isolated security incident in the integrator feature of AF Perps.
All other products (afSui, Pools, Farms, Agg, SOR) are completely unaffected & all users will be made whole.
This has been a scary week for crypto. AI tooling is developing rapidly, and we were among the almost a dozen protocols affected by hacks. We’re hopeful that by sharing our experience, we can help the broader crypto community learn and build back stronger.
Root Cause
The root cause was a signed integer issue in the integrator accounting logic. A malicious user was able to create their own integrator with a negative taker fee. This negative fee is then credited to a newly created account, which can be freely withdrawn from the vault.
This issue was introduced as part of a diff on August 29, 2025. The changes were audited by @osec_io in Nov 2025, but the issue was unfortunately missed.
Timeline
The attacker (suivision.xyz/account/0x1a65…) was first funded on 04-28 22:02:07 UTC with 405.24 SUI.
At 04-29 08:21:48 UTC, the attacker swapped 300 SUI for ~278 USDC via the SOR to obtain seed collateral for opening perp positions.
From 04-29 08:55:50 UTC to 09:31:49 UTC, the attacker drained ~1,139,927 USDC from AFperps across 17 attempts (11 successful, 6 failed).
Each of the 11 successful transactions was a single PTB that opened two accounts, registered the attacker as their own integrator with a negative 100,000 taker fee, executed a market order that crossed against a real counterparty’s maker order, then withdrew the resulting synthetic collateral as real USDC.
From 04-29 09:22:23 UTC to 10:45:22 UTC, the attacker laundered the proceeds through fresh single-use wallets and DEX swaps before depositing to Binance (suivision.xyz/account/0x9350…) (~$250K USDC), KuCoin (suivision.xyz/account/0x13c0…) (~$400K USDC), Huobi (suivision.xyz/account/0xe5c0…) (HTX) (~150K SUI), and HitBTC (suivision.xyz/account/0x8612…) (~$150K USDC).
Next Steps
Out of an abundance of caution, we’re conducting an additional audit before relaunching AFperps with a separate company. That being said, we also recognize that manual review alone is insufficient in 2026.
We are investing heavily to improve our AI-security workflows. AI tooling is developing rapidly, and we were among the almost a dozen protocols affected by hacks this week.
We’re thankful to all of our partners for their rapid response and help. In particular, Blockaid, ZeroShadow, OtterSec, Sui Foundation, and Mysten Labs.
