Networks, bridges & assets
Use the swap app's token pickers to choose a network, asset and route.
Network coverage
| Surface | Coverage |
|---|---|
| Swap app and CLI | 15 EVM networks, including the Sepolia testnet; see the network list |
| SDK v0.4.3 and hosted MCP | 14 EVM mainnets, including Arc (5042), with chain-specific orderbook and signing-domain helpers |
| Vault-order builder | @ophis/safe-swap v0.1.7 uses SDK v0.4.4 for ERC-20 presigned orders on 14 EVM mainnets, including Arc |
| Intent parser | 14 chain slugs, including arc |
| Standalone app through NEAR Intents | Bitcoin, Solana, Monad, Hyperliquid (Hypercore), X Layer, Sui, Tron, Starknet, Zcash |
| Orderbook operator | Networks |
|---|---|
| Ophis | Optimism, Unichain, Robinhood Chain, Arc |
| CoW Protocol | The other ten mainnets |
Use the SDK's chain-specific orderbook and signing-domain helpers for Arc orders.
| Arc setting | Value |
|---|---|
| Chain ID | 5042 |
| Orderbook | https://arc-mainnet.ophis.fi |
| EIP-712 settlement | 0x78799F98276efba1EdeeD32eae03a3fd8Cdfec3A |
| Gas currency | USDC |
| Native balance decimals | 18 |
| ERC-20 USDC decimals | 6 |
Arc's native and ERC-20 USDC interfaces access the same balance. Use the ERC-20 interface for token amounts and bridging. See Arc fees.
NEAR Intents swaps
The standalone app accepts external-source deposits through NEAR Intents and tracks destination delivery or refunds.
| Route requirement | Details |
|---|---|
| Additional sources and destinations | Bitcoin, Solana, Monad, Hyperliquid (Hypercore), X Layer, Sui, Tron, Starknet, Zcash |
| EVM receiving networks | Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche, Gnosis, Plasma, Robinhood Chain |
| Source funding | Quoted deposit amount, deadline and any required memo |
| Refund address | Address on the source chain |
| Hyperliquid (Hypercore) | Hypercore spot balances; exact-input routes with a source-chain refund address |
| Zcash | Mainnet transparent t1/t3 address |
| Network fees | Source-chain gas or transfer fees |
- Select your assets. Choose the source in You sell and the destination in You receive.
- Review the quote. Check the exact deposit, minimum receive amount, destination address, refund address and deadline.
- Fund the transfer. Confirm the quote to save the transfer record, then send the quoted deposit from your source wallet with any required memo.
- Track delivery. Keep the transfer record until delivery or refund completes; use the app's transaction-reference recovery to resume tracking.
Use a refund address on the source chain. For Zcash, use a mainnet transparent t1/t3 address. Copy the deposit amount and memo from the saved quote.
Circle bridges
The swap form bridges assets through Circle between Arc, Ethereum, Base, Arbitrum, Optimism and Unichain. USDC uses CCTP. EURC, cirBTC and WETH use Circle's token service where both networks have a supported mapping.
| Requirement | Details |
|---|---|
| Network set | Arc, Ethereum, Base, Arbitrum, Optimism, Unichain |
| Swap type | Exact input |
| Wallet | Personal EOA without smart-account code |
| Recipient | Connected wallet |
| Gas | Required for approvals, conversion and bridge transactions |
| Recovery | Keep the pending transfer record for delayed attestation or minting |
Ethereum WBTC to Arc cirBTC takes two steps: convert WBTC on Ethereum, then bridge cirBTC to Arc.
Check the quoted fees, minimum receive amount and destination gas requirements before signing. Follow the transfer until destination delivery completes.
Across bridges
The app also uses Across for supported cross-chain routes.
| App source route | Destination example |
|---|---|
| Optimism | Base |
| Polygon USDC | Robinhood Chain USDG |
For terminal swaps, use the CLI's bridge source list.
Tokenized assets
| Provider label | Source |
|---|---|
| Ondo, xStocks, Coinbase, bStocks, Reality | Configured token-list metadata for the chain and contract |
| bStocks on BNB | Configured CoinGecko lists and naming conventions |
| Reality/rStock on Arbitrum | Configured CoinGecko lists and naming conventions |
| Robinhood Stock Tokens | Canonical-registry and corporate-action multiplier checks |
Check the token contract, issuer disclosures and trading restrictions before swapping. Ophis displays Robinhood Stock Token restrictions and multipliers in the swap form.
Ethereum OTC trading
The OTC desk lets you create, fill and cancel public orders through immutable escrow on Ethereum.
| Requirement | Details |
|---|---|
| Assets | WETH, USDC, DAI |
| Wallet | Standard EOA without contract or delegated code |
| Fill type | All-or-nothing |
| Transactions | Create, fill, cancel and approvals cost gas |
| Expiry | No automatic onchain order expiry |
OTC orders stay open until filled or cancelled. A pending fill can race your cancellation; check the transaction result and order status.
