OpenOcean — OpenOcean aggregates DEX liquidity across 30+ chains including some non-EVM networks. It's a solid product, but many users search for a OpenOcean alternative because of thinner routing depth on major pairs versus the top aggregators.
10FI offers two API products: Swap API for best-route swaps and bridges, and Gasless API for sponsored approvals and swaps where supported — plus a flat 0.1% platform fee and a free developer tier.
| 10FI | OpenOcean | |
|---|---|---|
| Swap fee | 0.1% flat — nothing hidden | No platform fee on basic swaps; widget/API partners can add fees |
| Gas cost to user | Swap API: network gas where required; Gasless API: sponsored where supported | Limited; standard swaps require native gas tokens |
| Free API tier | 1,000 req/day · 30,000/month · no card | Free tier with API key registration |
| Custody | Non-custodial | Non-custodial |
| Native token needed | Gasless API: not on supported routes; Swap API: when route requires gas | Depends on mode |
| Pricing model | One number: 0.1% | Varies by product |
On eligible routes, instead of sending an on-chain transaction yourself, you sign a single off-chain message describing your trade. Competing resolvers pick it up, pay the gas, and settle it on-chain. Standard Swap API routes still use normal wallet transactions — users pay network gas when the winning route requires it.
10FI is a strong OpenOcean alternative: it aggregates major liquidity sources through a Swap API (best price, same-chain and cross-chain) and a separate Gasless API for sponsored execution on supported routes. Flat 0.1% fee, no subscription, free developer API (1,000 requests/day).
10FI charges a flat 0.1% platform fee. Swap API routes may include normal network gas paid by the user; Gasless API routes sponsor gas where supported. OpenOcean's pricing: No platform fee on basic swaps; widget/API partners can add fees.
Yes — through the Gasless API product on eligible routes. You sign one off-chain message; resolvers pay blockchain gas and settle on-chain. Standard Swap API routes may still require the user to pay network gas.
Yes. Funds move from your wallet through an audited settlement contract and back to your wallet in one atomic transaction. 10FI never holds your assets.
