FAQ

How is Ophis different from 1inch or Matcha?

Ophis batch-auction swaps use solver competition and signed limits to mitigate MEV. The optional natural-language API parses requests; it does not execute them. The fee model is published by settlement path. The standard schedule charges a 1 bp base; Ophis retains 80% of reference-quote improvement on volatile pairs, capped at 99 bps of volume, or 50% on stable pairs, capped at 20 bps. CoW-hosted chains additionally apply CoW Protocol fees upstream. Bridge costs are separate.

Do I need to connect a wallet?

Connect an EVM wallet for batch-auction orders. Externally funded NEAR routes can use a separate source wallet: review the quote, then send the specified deposit. Standard ERC-20 orders keep funds in the wallet until settlement; deposits have separate gas and recovery rules.

Which networks are supported?

The app supports batch-auction orders on 14 EVM chains: Ethereum, Arbitrum One, Avalanche, Base, BNB Smart Chain, Gnosis Chain, Ink, Linea, Optimism, Plasma, Polygon, Robinhood Chain, Unichain, and Arc. The standalone app also supports Bitcoin, Solana, Monad, X Layer, Sui, Tron, Hyperliquid (Hypercore), Starknet and Zcash as NEAR sources and destinations where assets and quotes permit. External-source swaps require a deposit and refund address. SDK v0.4.3 and hosted MCP chain lists cover the 14 EVM networks, including Arc; they do not build orders on the additional networks. See Networks & assets.

Is my trade protected from MEV?

Batch auctions use a uniform clearing price per token pair and offchain order submission to mitigate common MEV. Settlement transactions can still be public. Your signed limits are enforced, but this is not a guarantee against every front-running or sandwich scenario. See Security & audits.

What happens if no solver matches my intent?

An unfilled standard ERC-20 order expires after its validity window (30 minutes by default), leaving unsold funds in your wallet. Native-token deposits require an onchain refund; bridge routes follow provider recovery rules. Soft cancellation can race an in-flight settlement.

Who runs the solvers?

On the CoW-hosted chains Ophis surfaces, CoW's established solver network competes. On Optimism, Unichain, Robinhood Chain, and Arc, where Ophis runs its own stack, Ophis operates multiple routing lanes. Availability and pair coverage vary at runtime, so Ophis does not promise a fixed live count. 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?

Batch-auction orders carry Ophis's 1 bp base. On Optimism, Unichain, Robinhood Chain and Arc the backend adds the capped improvement policy to in-market orders. On CoW-hosted chains, appData carries both the 1 bp Volume entry and the pair-aware PriceImprovement entry: 80% capped at 99 bps for volatile pairs, or 50% capped at 20 bps for stable pairs. Full detail is 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.
