Who’s filling 1inch Aqua orders?

When you provide liquidity through 1inch Aqua, your position needs a counterparty before anything happens to your tokens. So who actually fills those swaps? 

You open an Aqua position, set your pair, price range and fee, and your tokens stay in your wallet. Then you wait.

For your position to generate trading activity, someone on the other side has to swap against that liquidity. In Aqua terminology, you are the maker. The party filling the swap is the taker.

Currently, those takers are verified 1inch resolvers - independent participants that have completed the 1inch resolver onboarding and verification process.

What does a resolver do?

Resolvers are independent professional market makers running automated systems that look for swaps they can fill. They are already a core part of 1inch’s intent-based infrastructure, where they compete to fill users’ orders. You can read more about 1inch resolvers here.

With Aqua, their role is slightly different. The liquidity already comes from Aqua makers. Resolvers act as takers, accessing that liquidity when it offers a suitable route for a swap.

1inch Pathfinder, the underlying routing algorithm, discovers available Aqua liquidity off-chain and can route swaps against it. At launch, access to Aqua liquidity through 1inch routing is restricted to approved resolvers that have been verified and hold the required onchain credential.

What happens when a resolver fills your position?

Nothing leaves your wallet simply because you created an Aqua position.

When a resolver fills a swap against it, Aqua’s SwapVM handles the transaction atomically. The relevant token is pulled from the maker’s wallet and the incoming token is pushed back as part of the same transaction. Either the entire swap succeeds or it does not.

That is what makes Aqua different from a conventional liquidity pool. You do not deposit assets first and wait for someone to trade against a pool balance. Your wallet balance remains under your control until an actual fill occurs. You can learn more about self-custodial liquidity on Aqua here.

Why restrict Aqua takers at launch?

Aqua’s maker side is permissionless: liquidity providers can create and close positions without verification. Taker access is more controlled at launch.

Only verified resolvers can currently fill Aqua strategies through the 1inch routing infrastructure. Each approved resolver uses an onchain credential that allows the Aqua contracts to verify that the transaction comes from an authorized taker. This staged approach lets taker-side execution quality and accountability be established while the ecosystem around shared liquidity matures.

So the flow is straightforward: you provide the liquidity, Pathfinder can discover it, and approved resolvers can use it when filling swaps.

As Aqua develops, its open architecture creates room for a broader ecosystem around shared liquidity. For now, however, if you are wondering who is on the other side when your Aqua position gets filled, it is a verified, independent resolver.
