The buzz in the DeFi space just got louder with Aftermath Finance announcing the imminent launch of its perpetuals platform. Pre-deposits are set to open later this week, marking a significant milestone for onchain trading. But what makes this launch stand out? It's all about building on Sui, a Layer 1 blockchain that's proving to be a powerhouse for running fully onchain orderbooks without the usual headaches of high gas fees or latency issues.

For those new to the term, perpetual futures (or "perps") are derivative contracts that let traders bet on the price of assets without an expiration date. They're popular in crypto for leveraging positions on everything from Bitcoin to emerging meme tokens. Aftermath's approach takes this a step further by making the entire orderbook—where buys and sells are matched—fully onchain. That means everything is verifiable and governed by Sui's validators, with no offchain sequencers or restricted APIs getting in the way.

Why Sui? The secret sauce is in Sui's object model. Unlike the Ethereum Virtual Machine (EVM), which treats everything under a single account model leading to serialized execution, Sui handles each market and order as separate objects. This setup allows independent markets to operate without interfering with each other. So, trading BTC perps won't slow down SUI perps. Within a market, orders are still sequenced deterministically, but there's no global lock bogging down the system.

Sui's been battle-tested with its spot market protocol, DeepBook, which has been live for over a year. Check out the performance metrics here. It's handled real volume without crumbling, setting the stage for perps.

Adding to the efficiency is Mysticeti v2, Sui's consensus engine. It ditches the single-proposer model that plagues many chains, where one entity decides transaction order. Instead, every validator proposes in each round, and consensus commits leaders deterministically. This ensures all validators see the same order, making matching and settlement reliable and fair. Dive deeper into Mysticeti here.

Then there's the economic magic: Parallel Transaction Bundles (PTBs) and storage rebates. PTBs allow batching multiple actions cheaply, while storage is rented rather than burned. When orders are canceled or matched, storage gets returned, sometimes making transactions net negative in cost—users can even get paid for cleaning up state. This is a game-changer for high-frequency trading bots, which would otherwise rack up insane fees on other chains.

What does this mean for the community? Aftermath is introducing AFLP, the first community-owned perpetual market maker on Sui. By depositing into the vault, you provide liquidity and handle liquidations across perp markets. It's tokenized and shared, opening up composability that's impossible when logic lives offchain.

Looking ahead, anyone can build their own API on top since markets are objects—no centralized gateways or private engines. Plus, programmable cancel priority lets makers pay a transparent fee for faster cancellations, leveling the playing field.

If you're into DeFi or trading meme tokens with leverage, keep an eye on Aftermath. Details on pre-deposits drop tomorrow. This could be the push Sui needs to dominate onchain perps, blending speed, cost-efficiency, and true decentralization. Stay tuned for more updates as the launch unfolds.
