OpenOcean Swap

What is OpenOcean Swap?

OpenOcean Swap is a decentralized aggregator service that enables swapping tokens in the DeFi world. It leverages liquidity across multiple decentralized exchanges (DEXs) and bridges to deliver optimal routes, minimizing slippage, gas fees, and maximizing returns. It also supports cross‑chain swaps, Ultra Mode (gas‑abstraction), API/SDK integrations, and advanced routing algorithms. :contentReference[oaicite:0]{index=0}

It offers features like:

• Same‑chain swaps across many EVM and non‑EVM chains. :contentReference[oaicite:1]{index=1}
• Cross‑chain swaps using bridges like Celer cBridge, Multichain, etc. :contentReference[oaicite:2]{index=2}
• Ultra Mode: gas‑less trading via Permit2, small fees for stable vs volatile pairs, MEV protection. :contentReference[oaicite:3]{index=3}
• Developer tools: APIs, SDKs, Widgets for integration. :contentReference[oaicite:4]{index=4}

How OpenOcean Swap Works

Here's a simplified flow for using OpenOcean Swap:

1. Go to the OpenOcean website (app.openocean.finance / swap module) and connect your wallet. :contentReference[oaicite:5]{index=5}
2. Select the token you want to trade (input) and the token you want to receive (output), and select the chain. :contentReference[oaicite:6]{index=6}
3. Ultra Mode may be enabled by default. If you haven’t used a token before, you’ll need to approve it once (this costs some gas). :contentReference[oaicite:7]{index=7}
4. The protocol’s routing engine scans multiple liquidity sources (DEXs, bridges, etc.), calculates the best route taking into account price, slippage, gas, bridge fees. :contentReference[oaicite:8]{index=8}
5. Confirm the transaction in your wallet. If Ultra Mode is used, gas cost is abstracted away (except token approvals). :contentReference[oaicite:9]{index=9}
6. For cross‑chain swaps, the system uses semi‑atomic or atomic bridge protocols so that funds are transferred reliably. :contentReference[oaicite:10]{index=10}

Key Advantages & Features

• Ultra Mode / Gasless Trades: Swap without holding native gas tokens in many cases; includes Permit2 for secure approvals. :contentReference[oaicite:11]{index=11}
• Cross‑Chain Support: Supports many chains, bridges, and tokens (1,100+ tokens) across networks like Ethereum, BNB Chain, Polygon, Arbitrum, etc. :contentReference[oaicite:12]{index=12}
• Smart Routing & Deep Liquidity: Trades are split and routed for optimal price, using a wide pool of liquidity sources. :contentReference[oaicite:13]{index=13}
• Developer Friendly APIs & Widgets: OpenOcean offers integration tools for swap, widget, cross‑chain swaps, allowing builders to embed functionality. :contentReference[oaicite:14]{index=14}
• No Extra Aggregator Fees on Many Swaps: OpenOcean often does not add extra markup beyond DEX/bridge fees. :contentReference[oaicite:15]{index=15}

Common Issues & Troubleshooting

Despite its strengths, users may experience problems. Here are frequent issues and how to solve them:

OpenOcean Swap Not Working / Unable to Connect Wallet

• Check wallet extension or mobile wallet is unlocked and switched to the correct network. Wrong chain will block swaps. :contentReference[oaicite:16]{index=16}
• Ensure you’re on the official OpenOcean site (e.g. app.openocean.finance) to avoid phishing. :contentReference[oaicite:17]{index=17}
• Clear browser cache or disable conflicting browser extensions (ad‑blockers, privacy blockers) that may block scripts or popups.

Swap Declined / Transaction Fails / High Slippage

• Slippage tolerance too low or price moved too much between quote and execution. Increase slippage settings if necessary.
• Liquidity insufficient for given token pair or in selected chain. Splitting swaps into smaller amounts or choosing a more liquid pair may help.
• Make sure you have enough native token (ETH, BNB, etc.) for gas, unless Ultra Mode abstracts gas. Even with Ultra Mode, first‑time approvals need some gas. :contentReference[oaicite:18]{index=18}

Cross‑Chain Swap Problems / Assets Not Received

• Confirm destination address and chain are correct. Mistakes here can cause permanent loss.
• Wait for bridge confirmations — cross‑chain bridges can have delays. Use blockchain explorers to track. :contentReference[oaicite:19]{index=19}
• If a cross‑chain swap is interrupted, semi‑atomic mechanisms often refund source if the swap fails before completion. Check transaction details. :contentReference[oaicite:20]{index=20}

Ultra Mode Issues / “Requires Gas” or “Approval Still Needed”

• The very first time you use a specific token, even in Ultra Mode, you must approve the token (on‑chain), which requires gas. :contentReference[oaicite:21]{index=21}
• Ensure you used Permit2 where required (permission standard). Ultra Mode uses this to manage token approvals more efficiently. :contentReference[oaicite:22]{index=22}

FAQ: OpenOcean Swap — What Users Ask

Q: Why is OpenOcean Swap not working for me?

A: Usually because of wallet not connected, wrong network selected, or blocked by browser settings. Verify domain and chain, reload or switch wallets.

Q: What is Ultra Mode and do I always need it?

A: Ultra Mode is OpenOcean’s gas‑abstraction mode using Permit2, helping reduce friction. You’ll still need to approve a token once, which costs gas. For many swaps, Ultra Mode helps avoid requiring native tokens for gas. :contentReference[oaicite:23]{index=23}

Q: What fees does OpenOcean charge?

A: OpenOcean typically doesn't add extra aggregator fees beyond what liquidity sources and bridges charge. In Ultra Mode, there is a small fee: ~0.04% for stable pairs, ~0.2% for volatile pairs. :contentReference[oaicite:24]{index=24}

Q: My cross‑chain swap is stuck or assets not showing — what to do?

A: Check transaction status on source and destination block explorers; confirm the bridge used; allow sufficient time; contact support with tx hash if needed. :contentReference[oaicite:25]{index=25}

Q: Is OpenOcean Swap safe to use?

A: Yes — it’s non‑custodial, with audited smart contracts. But users should always double‑check URL, token contracts, route details, and gas/bridge fees. :contentReference[oaicite:26]{index=26}

Q: What chains and tokens are supported?

A: Over 18‑40+ chains depending on feature (same‑chain, cross‑chain, Ultra Mode). Supports 1,000+ tokens, with bridges like Celer, Multichain etc. :contentReference[oaicite:27]{index=27}
