Ecosystem Showcase & Launches

The on-chain simulation before showing a quote is the part that stands out to me. Fast routing is useful, but verifying the exact route before execution makes the quote much more trustworthy.

Today we're introducing AchSwap Aggregator V2: a major upgrade to the infrastructure behind AchSwap's routing, pricing, liquidity discovery, gasless execution and developer access.

V2 is more than a speed boost or a new API. We rebuilt how AchSwap discovers liquidity, evaluates routes, prices trades and executes swaps.

find more liquidity, evaluate more routes, return better prices, and do it faster.

 And open that infrastructure to developers, not only to AchSwap users.

Speed matters in aggregation. Every millisecond gives the market time to move, liquidity to shift, or another aggregator to answer first.

V2's routing engine returns a quote in under 500 ms. In our latest benchmark, the median quote took about 140 ms and 9 in 10 arrived in under 360 ms, including the on-chain check of the route (next section). The previous engine took about 5 seconds: 

Faster responses for apps built on the API

Better routing no longer has to cost speed.

A fast quote is only useful if it is real.

Before AchSwap shows you a quote, it runs the exact route on the live chain, through the same contract that will execute your swap, at the block the quote was priced on. The number you see is what that run actually paid out.

If a route would pay less than the engine predicted, it is corrected or dropped. It is never shown to you.

Speed only matters if the route is competitive. V2 does not stop at the first route that can fill a trade. It searches for the one that pays you the most:

 a trade across several pools when one pool alone would move the price too much

 when the best path runs through other tokens

, so a route that quotes more but costs more to execute does not win by mistake

: tokens with transfer taxes or sell restrictions are never routed

The route for one trade can be completely different from the route for another, even on the same pair. That is what we believe an aggregator should do: 

search the market instead of assuming the market.

No aggregator wins every trade. Markets, liquidity, gas costs and route availability all change. So when you swap on AchSwap, the app also compares its route with other aggregators and gives you the best result after gas.

How competitive is V2 on its own? In our latest benchmark against a leading aggregator, AchSwap's price matched or beat it on 155 of 159 trades, and beat it by more than 0.02% on 32 of them.

More pools mean more potential routes. More tokens mean more possible paths. Instead of relying on a short list of predefined paths, AchSwap is building a complete liquidity discovery layer for the chain.

Scale only helps if it can be searched quickly. That is why V2 pairs this coverage with the faster engine above.

Gasless swaps are simpler in V2. Before, a gasless swap could ask you for an extra signature. Now each swap is 

: you sign, and AchSwap's relayer submits the swap and pays the gas.

The first time you go gasless with a token, your wallet approves it once. After that, every gasless swap with that token is one signature and no gas.

Gasless swaps are available from USDC, EURC and cirBTC, above a small minimum.

 Gasless should make swapping easier, not add another step.

V2 is not only for AchSwap. With this release we are opening the aggregation engine to developers through the 

Wallets, apps, protocols and trading interfaces can add AchSwap's routing without building an aggregator themselves:

 from AchSwap's routing engine, across all the liquidity it indexes on Arc

, simulated before they are returned and executed through AchSwap's on-chain router

: charge up to 1% on each swap, paid to your address on-chain in the same transaction

 and request a key through the contact details there. Once your request is approved, you receive an API key and everything you need to start.

 From a swap interface to aggregation infrastructure

AchSwap started with a simple idea: give users better access to liquidity. Doing that well now takes far more than an interface: pool indexing, route computation, pricing, gas estimation, on-chain verification, gasless execution and developer APIs.

Aggregator V2 is our investment in that layer. The interface you see is one part of AchSwap. Behind it, the engine processes liquidity and market data around the clock to decide how each trade should execute.

V2 is a foundation, not a final version. As new liquidity sources and pool designs arrive, we will keep improving the engine on every front: speed, coverage, routing, pricing and execution.

More liquidity. More routes. Better pricing. Faster execution. Less friction. More ways to build.

The rebuild is live, and this is only the beginning.
