Natural-language intent parser for DEX swaps across 11 EVM chains.

About Ophis

Ophis is an intent-based DEX aggregator offering MEV-protected swaps for stablecoins and tokenized assets, including Stock Tokens and tokenized stocks. Trades are submitted as signed intents that competing solvers fill through a batch auction, drawing liquidity from aggregated DEXs and AMMs such as Uniswap, Curve, Balancer, and SushiSwap, with settlement handled by a forked CoW Protocol stack and cross-chain delivery via NEAR Intents and Across. Users can trade directly with their own wallet across multiple chains including Ethereum, Solana, Bitcoin, and others, or via a natural-language Intent API that parses swap requests into structured fields.

The product is aimed at both individual traders and developers/agents building on top of it. Traders get a swap interface with quote review, spending limits, and a transaction explorer for tracking order status and settlement. Builders can integrate through a hosted MCP server, a public Intent API, or the dependency-free @ophis/sdk, which provides per-chain orderbook hosts, EIP-712 signing domains, and agent-safety checks such as receiver-pin validation and chain-id verification.

Pricing for standard-policy swaps is a 1 basis point base fee plus capped improvement capture, with additional upstream CoW fees on hosted paths; Arc uses a separate release configuration. High-volume agents and DAOs can receive automatic fee rebates through a rebate-indexer. Security review tooling from Trail of Bits (Slither, Echidna) was used in development, and compute infrastructure is provided by Aleph Cloud.
