Getting started

Ophis turns a sentence into a settled, MEV-protected swap. There's no token-picker to fight and no router to configure — you describe the trade, review it, and sign.

Your first swap

1. Open ophis.fi and connect a wallet.
2. Type what you want in plain English, for example:
   • swap 100 USDC for ETH on Base
   • buy 50 USDC of PEPE on ethereum
   • 1 ETH to USDC on op
3. Ophis parses your sentence into a structured order (sell token, buy token, amount, chain) and pre-fills the swap form.
4. Review the quote and sign the order with your wallet. Nothing leaves your wallet until a solver settles the trade.

:::note Non-custodial by design Ophis never takes possession of your funds. The signed order is broadcast to the solver network; your tokens move only when a solver settles the batch on-chain. :::

How it works

Three steps from your sentence to settlement:

1 · Intent — parse the request

You type a swap in plain English. An open LLM (LibertAI's Qwen 3.6 27B, hosted on Aleph Cloud) extracts the sell token, buy token, amount, and chain into a structured order. The model runs behind a server-side proxy so its API key never reaches the browser. See the Intent API for the public endpoint.

2 · Auction — solver competition

Your signed order is broadcast to a batch auction. Solvers race to find the best path — an on-chain DEX, a peer-to-peer match against another order in the same batch, or a cross-chain route — and bid for the right to settle it.

3 · Settle — on-chain, MEV-protected

The winning solver settles your order in a batch where every trade clears at the same uniform price. There's no front-running, no sandwiching, and no priority-gas auction to win, because the protocol does not reorder transactions for value.

For the full lifecycle, see How it works.

Supported networks

Ophis surfaces 11 EVM chains as source / destination in the network selector:

Ethereum	Arbitrum One	Avalanche
Base	BNB Smart Chain	Gnosis Chain
Ink	Linea	Optimism
Plasma	Polygon

Plus Solana and Bitcoin as cross-chain destinations via NEAR Intents — trade from any EVM source chain to those networks without a second wallet. You paste a destination address and sign with your EVM wallet; NEAR Intents brokers the bridge.

Around 150+ tokens are recognised across stablecoins, ETH/BTC pegs, DeFi blue-chips, AI/RWA, memes, and gaming.
