Liquidity infrastructure for stablecoin issuers. One commitment backs every pool and every chain your asset trades on.
Made by Cross Margin Labs
Before
Minting is the easy part. Being tradeable across nine chains means capital on nine chains, split across every pair. The treasury ends up divided twenty ways, most of it sitting idle.
After
One commitment backs every pool and chain at once. Capital stays put until a swap needs it. Same treasury, multiplied depth.
Locking liquidity in an asset once lets it back liquidity across every pool and chain that asset trades on at the same time, instead of splitting the same capital across siloed positions.
Traditional AMMs force you to divide capital into isolated positions. Aqua0 keeps it in one place and makes it available to every pool and chain at once, injected the moment a swap lands and returned immediately after. The demo below uses two pools so the mechanism is easy to follow. In production a single commitment typically backs many more.







This example uses 2 pools so the reuse mechanism stays easy to follow. Scaled to every pool and chain a single locked position typically backs in production, that same reuse effect delivers far higher capital efficiency than siloed liquidity.
When a trader swaps from one chain to another, the swap runs on the source chain and a filler on the destination chain pays out at once. The swap's output then bridges across in the background to repay the filler. This is one fill, end to end.

2.5 WETHFronting is temporary by construction. The bridged output repays the filler on the filler's own chain, plus a fee, so every side ends up whole.

Finalists at ETHGlobal Buenos Aires, where Aqua0 was born. Later selected as 1 of 4 teams worldwide for ETHGlobal Spotlight NYC (June 2026), with our own booth.
A single commitment backs capital on every chain Aqua0 is live on. No manual bridging, no manual rebalancing.
Backed by angels from top protocols, including Sergej Kunz (co-founder of 1inch) and team members from Altitude.
The private beta is live under a TVL cap and an allowlist. Of every swap fee, 80% goes to the liquidity providers whose liquidity filled the trade and 20% goes to Aqua0. Traders pay the same price. Third-party costs (gas, LP fees, other protocols) are not charged by us and are not included.
The private beta is live across nine chains. Join the allowlist, or talk to us directly if you issue a stablecoin.
