Getting started

Choose your tokens and networks, review the quote, then authorize the displayed order or fund the quoted deposit from your source wallet.

Your first swap

1. Open the swap app. Connect your EVM wallet for batch-auction swaps; externally funded routes can use a separate source wallet.
2. Select the token and network you want to pay from, then enter the amount.
3. Open You receive to select the destination network and token. For a cross-chain route, check the destination-address and wallet requirements.
4. Review the quote, fees, destination address, and spending limit. For a batch-auction swap, approve the displayed amount if needed and sign the order. For an externally funded swap, also enter a source-chain refund address, confirm the quote, and send the specified deposit before its deadline, including any required memo. Keep the saved transfer until delivery or refund.

Non-custodial by design

Ophis does not hold your signing key. Standard ERC-20 orders stay in your wallet until settlement; native-token orders and bridge routes can require an onchain deposit or transfer first. Their recovery and trust assumptions are route-specific; see Networks & assets.

How it works

The following steps describe batch-auction orders. Externally funded NEAR and direct Circle routes follow their provider's deposit and delivery lifecycle; see Networks & assets.

1 · Choose tokens and amount

The swap form opens directly. Select the assets and networks, enter the amount, and review the quote and spending limit. Developers and agents can still use the Intent API for natural-language requests.

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, Unichain, Robinhood Chain, and Arc, 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 uses uniform clearing prices for each token pair. Your signed limit price is enforced on-chain, and Ophis orders are not exposed as public-mempool router swaps. On Robinhood Chain, the sequencer is first-come-first-served, so paying a higher priority fee does not buy an earlier place in the ordering.

For the full lifecycle, see How it works.

Supported networks

Ophis 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 (plus the Sepolia testnet). Same-chain trading and cross-chain route availability are separate: a listed chain does not guarantee every source/destination pair.

Arc is available in the swap app (chain ID 5042). Its native gas currency is USDC; Circle routes include USDC and mapped expanded assets, plus Ethereum WBTC to Arc cirBTC through a separate conversion leg. See the restrictions and recovery model in Networks & assets. SDK v0.4.3 and the hosted MCP chain lists also include Arc.

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

The standalone app also supports Solana, Bitcoin, Monad, Hyperliquid (Hypercore), X Layer, Sui, Tron, Starknet and Zcash as sources and destinations through NEAR Intents, where live assets and quotes permit. Select the source in You sell to enter the externally funded flow; select the destination in You receive. These networks do not gain a CoW orderbook or SDK signing domain. See the funding, address and recovery requirements.

The current token catalog covers stablecoins, ETH/BTC pegs, DeFi blue-chips, AI/RWA, memes, and gaming. The in-app token selector is the live source of truth because token availability can change by chain.

Robinhood Stock Tokens

Robinhood Chain includes tokenized equities and ETFs. Ophis verifies a selected Stock Token against Robinhood's live canonical deployment registry and shows its corporate-action multiplier and trading restrictions in the swap form. A split can change the share-equivalent display without rebasing the raw ERC-20 balance; the executable trade price remains the signed Ophis solver quote.

• Robinhood Chain network configuration
• Stock Token integration and multiplier
• Bridge assets to Robinhood Chain

Offchain ERC-20 order signatures are gasless. Wallet approvals, wrapping, and other direct transactions still require ETH. Robinhood's public RPC is rate-limited; production integrations should use a supervised provider endpoint and reserve the public RPC for wallet configuration and fallback use.

Building on Ophis?

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