[Kevin | Aftermath (🥚, 🥚) @KevinAftermath]

Yesterday marked our largest update to AF perps since our initial launch; not only did we launch our 11th market, AF100USD, we increased leverage across 5 markets, rolled out One-Click Trading (1CT), enabled an improved version of Dynamic Gas for AF perps, added the Gas Pool and Agent Wallet tabs to our UI, improved the metrics available on your account page, and released v2.5.0 of our skills.

Each of these will get its own dedicated post on @AftermathFi but prior to that I wanted to shed some light on how each feature works and how to best utilize them.

AF100USD
AF100 marks our 11th market since launch, 6th market powered by @PythNetwork Pro, 5th Equities market, and 4th market using our onchain, rolling-contract-based formula for deriving price feeds.

One-Click Trading
This has been a long requested feature and our biggest pain point since launch: clicking an approve button on all transactions is poor UX and, in some cases, a blocker for integration in the first place.

Combining Sui's Sponsored Transactions with in-house developed infra, we were able to provide auto-accept functionality across all AF Perp transactions. Approve once at the start of your session and never deal with a wallet popup for the remainder of your session.

When you first visit our /perpetuals page, you will be prompted to enable 1CT. To do so, you need to pre-reserve SUI to be used as gas for all auto-approved transactions. After depositing, we will create an agent wallet for your account and execute all transactions through this agent wallet using the gas you reserved. You will need to periodically top up the reserved gas; you can either manage this and the agent wallets explicitly on the Gas Pool and Agent Wallet pages or you will be prompted to top up automatically if your reserves start to get too low.

Dynamic Gas
We originally launched Dynamic Gas back in the end of 2023 to allow afSUI holders to pay gas using our LSD. We quickly expanded the scope of Dynamic Gas to include many assets, including @circle's USDC.

For AF perps, we had to completely redevelop Dynamic Gas from the ground up-to not increase the average cost of any AF perp transaction-and closely coupled it with our 1CT implementation. When enabling 1CT, you have the option to select any asset as the gas token or mix and match between many tokens.

The next unlock for AF perps is finally here: quick, frictionless transactions payed for in any asset you desire.

Gas Pool
Want to view how much gas you have left reserved for 1CT? Visit our new Gas Pool page to deposit into and withdraw from your reserves and manage the accounts that have access to these reserves.
https://t.co/AwtOTxdoVL

Agent Wallet
Want to grant new or revoke and view pre-existing agent wallets tied to your account? Visit our new Agent Wallets tab to handle all of these interactions. You'll see all of the active agent wallets you've explicitly enabled as well as the agent wallets addresses tied to your address underpinning 1CT.
https://t.co/IeosgoDJ6S

Account Page
We've added account-individualized metrics, across Maker / Taker volume and fees, to give you more insight into your historical performance and help you correlate between your epoch activity and epoch-end rewards.

These same metrics are also visible on all Vault pages for both depositors and Vault curators.

Skills
v2.5.0 added support for all of the above as well as a few new endpoints and minor improvements to previous endpoints. View and download the latest skills at https://t.co/X2CymOxJab

All of these features are here to kick off the start of our epoch 4! Use these new features to your advantage and participate to be eligible for 50k of SUI rewards at the end of epoch 4 (April 12th) split across AFLP and AF perp traders.

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 (https://t.co/I6h41yV7P3) 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 (https://t.co/GhFCjQhouT) (~$250K USDC), KuCoin (https://t.co/F4O7trwVwZ) (~$400K USDC), Huobi (https://t.co/9TBZOPyPDh) (HTX) (~150K SUI), and HitBTC (https://t.co/ZYToOISmm7) (~$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.

[Sui @SuiNetwork]

Today Aftermath Finance sustained an exploit of its perpetuals protocol on Sui which was subsequently paused.

The Sui Foundation, in partnership with Mysten Labs, has committed to working with Aftermath Finance to both ensure fund recovery to users and continuity of the Aftermath protocol.

Aftermath will provide further updates on fund recovery shortly.

Uranium is starting to gain attention from a lot of big accounts as its structural supply deficit widens. As the world learns to reimbrace clean nuclear energy, demand will only continue to grow.
@AftermathFi maybe the first perp dex to list $URA but I suspect it wont be the last. 🥂

i work in a company where eggs speak and i cannot talk about egg publicly (i have zero to no information on whats inside)

people somehow talk about egg without any knowledge, interesting

Thanks for being an early user

We are in the "all at once" phase. Sui is becoming cheaper to interact with day by day.

[Kevin | Aftermath (🥚, 🥚) @KevinAftermath]

Slowly, then all at once

[Kevin | Aftermath (🥚, 🥚) @KevinAftermath]

@Cleverman_Alex ya its correct

@Cleverman_Alex Let's make SUI the cheapest L1 to transact on

[as required. @0xasrequired]

aftermath will probably be the best TREAD points farm

> -0.5bps maker fee

> but they have builder codes, so tread's 2bps builder fee applies

> but that means that aftermath vol earns 4x tread pts

--> 1.5bps fees for 4x tread pts, compared to the next cheapest 4x tread pts source (HIP-3) at 2.3bps

> ofc you also earn aftermath pts

> aftermath also distributed 50k SUI every 2 weeks for trading, as required.

Great initiative! @StudioMirai has reduced RGP to 100 MIST to support @AftermathFi and @codanetwork high transaction volume features that benefit from low gas fees.

@0xAmoghGupta You should add validator stake as a column

[Kevin | Aftermath (🥚, 🥚) @KevinAftermath]

ceteris paribus

An important assumption you made there

Lobby your local validator today.

Let’s make Sui the home for onchain financial transactions.

[Aftermath Finance (🥚, 🥚) @AftermathFi]

We are excited to announce that @AftermathFi, the perp exchange and @SuiNetwork validator, are proposing an 80% cut to Sui's RGP.

We ask all @SuiNetwork validators to reduce their RGP to ≤ 100 MIST.

We believe that this is both the right step and the right moment to align Sui with the rest of the market.

Here's why: Sui today charges ~6x more than Solana for a simple transfer, despite having the competitive edge when it comes to faster finality, parallel execution, and greater flexibility through PTBs.

A single order on Phoenix (Solana) costs $0.0011. On Aftermath, $0.0018. Both products have been heavily optimized for their respective stack. The remaining cost imbalance is due to how either chain charges for computation.

Shouldn't we be incentivizing on-chain activity?

After less than two months, Aftermath already consumes ~10% of Sui's daily gas. ~216k txs/day, ~2.1M on-chain events/day, 15 live markets across crypto, equities, and commodities. All fully on-chain. All paying gas on every quote, cancel, and fill.

Lowering gas doesn't just save money for existing users; it unlocks entirely new participants - market makers, institutions, agents traders - who were previously priced out of high-frequency trading on Sui.
