The mechanics, honestly.

In an ordinary pool, capital sits in the pool around the clock and earns only swap fees. In a DualPool, capital rests in lending vaults between trades. When a swap arrives, the pool pulls exactly what it needs, fills the trade with tightly concentrated liquidity, and puts everything back to work — all inside the swap's own transaction. Nobody waits, and nothing sits idle by design.

If you're swapping

You get deep quotes near the peg at a 0.001% fee, because the pool's full inventory concentrates around the current price for exactly the length of your trade. Quotes are estimates — the slippage bound you set is what actually protects you — and each swap does more onchain work than a vanilla one, which costs a few extra cents in gas. Swapping walks through the widget end to end.

If you're providing liquidity

You deposit USDC and USDT once and hold a share of the pool. Its value grows two ways at the same time: continuously, from vault lending yield, and with every trade, from swap fees. There is nothing to stake, claim, or rebalance, and you can withdraw at any time — even if swapping is paused. Providing liquidity covers deposits, withdrawals, and your position page.

The honest bits

• Some inventory naps between trades. Tokens coming in from a swap settle a beat too late to reach the vault, so they wait as “claims” — earning nothing — until flow in the other direction sweeps them back. Sustained one-way flow makes this drag noticeable; every inventory view in the app badges it.
• Swaps cost more gas. One trade does a full withdraw-deploy-fill-redeposit cycle. Traders pay it, and at today's fees it comes to cents — but it is real, and routers weigh it.
• Quotes are indicative. The number you see is an estimate, not a promise. The transaction enforces the bound you chose, and reverts rather than fill worse.
• The vaults are a real dependency. Idle capital lives in third-party lending vaults. That is where the yield comes from — and it is the protocol's biggest external trust assumption. Risks & security spells it out.

Audited

DualPool was audited by OpenZeppelin (May 20 – June 17, 2026): no critical and no high-severity issues, and every finding resolved.

Measured, not projected

From the live USDC/USDT pool's first day on mainnet: balanced $100 round-trip flow paid about 0.1 bps per leg, and net LP return annualized to roughly 7% — about half durable vault yield, the rest early-volume fees. Organic aggregator flow arrived within hours.
