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 your own words, 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.

Non-custodial by design

Ophis never takes possession of your funds. The signed order is broadcast to the solver auction; 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 the swap as a sentence. 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. On Optimism and Unichain, Ophis currently operates the solver itself, competing across several routing strategies, see How it works.

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 12 EVM chains as full source and destination in the network selector: Ethereum, Arbitrum One, Avalanche, Base, BNB Smart Chain, Gnosis Chain, Ink, Linea, Optimism, Plasma, Polygon, and Unichain (plus the Sepolia testnet). On any of these you can both pay from and receive into your EVM wallet.

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

In addition, Solana and Bitcoin are available as cross-chain destinations only via NEAR Intents: trade from any EVM source chain to those networks without a second wallet. They are not source chains, you cannot start a swap from a Solana or Bitcoin balance. You paste a destination address and sign with your EVM wallet; NEAR Intents brokers the bridge.

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

Skip the UI entirely, the Intent API exposes the same natural-language parser as a public endpoint, and the AI agent guide shows how to wire it into an agent.
