FAQ

How is Ophis different from 1inch or Matcha?

Ophis uses batch auctions and a solver competition to settle every order at the best on-chain price, with MEV protection by construction. The natural-language input lets you skip token-pickers entirely. And the fee model is simple and published all-in: a flat 0.10% (10 bps) Ophis fee on trade volume, with a reduced 0.01% (1 bp) on same-chain stablecoin-to-stablecoin swaps. On the Ophis-operated chains (Optimism, Unichain) that is the entire cost and 100% of price improvement is returned to you; on CoW-hosted chains CoW Protocol's own fees apply on top (0.02% volume fee, 0.003% on correlated pairs, plus 50% of quote improvement, capped at 0.98% of volume). For example, swap 1,000 USDC on Optimism and the fee is 0.10% = 1 USDC, all-in.

Do I need to connect a wallet?

Yes, you sign your swap order with your own wallet. Ophis is non-custodial; the signed order is broadcast to the solver auction and your funds move only when a solver settles the batch.

Which networks are supported?

12 EVM chains as source / destination: Ethereum, Arbitrum One, Avalanche, Base, BNB Smart Chain, Gnosis Chain, Ink, Linea, Optimism, Plasma, Polygon, and Unichain. Plus Solana and Bitcoin as cross-chain destinations via NEAR Intents. See Getting started.

Is my trade protected from MEV?

Yes. The batch auction settles every order in a batch at the same uniform clearing price. Front-running and sandwich attacks are eliminated by construction, there is no priority-gas auction to win because the protocol does not reorder transactions for value. See Security & audits.

What happens if no solver matches my intent?

The order expires after its configured validity window (30 minutes by default) and your funds stay in your wallet. You can resubmit, change parameters, or cancel at any time.

Who runs the solvers?

On the CoW-hosted chains Ophis surfaces, CoW's established solver network competes. On Optimism and Unichain, where Ophis runs its own stack, Ophis currently operates the solver itself, competing across several routing strategies (a baseline router plus multiple DEX aggregators) per batch; the on-chain allowlist gates who may settle, and more solvers can be authorized over time. Your protection is the same either way: the signed order's limit price is enforced on-chain, so no solver can fill it worse than the price you accepted.

How are partner fees collected?

Via the CoW Protocol partner-fee field in the order's appData, set to the volume shape { volumeBps: 10, recipient }, taken from the trade output at settlement. Full detail on the Fees & rebates page.

Is Ophis open source?

Yes, full source at github.com/ophis-fi/ophis. Ophis is an open-source DEX aggregator frontend with an added natural-language intent-parsing layer, built on CoW Protocol's settlement primitives.

Can I use Ophis's intent parser in my own app?

Yes. The natural-language → structured-order endpoint is publicly available at POST /api/intent with a 30 req/min/IP rate limit, no auth, and no key. Build it into a Telegram bot, browser extension, agent framework, or your own UI. See the Intent API reference and the AI agent integration guide.
