Swap Terminal Overview
The Swap product is onchain.cc's cross-chain spot trading terminal — built for traders who want fast execution, best-price routing, and full self-custody, without paying the inflated fees charged by most DeFi frontends. Trade across 17+ chains from a single interface. (For pre-graduated pump.fun tokens, see Degen. For perpetual futures, see Perps.)
What It Is
onchain.cc is a DEX terminal that spans 17+ chains. You connect your self-custody wallet, search for any token, and trade directly on-chain. There is no custodian, no order book, and no intermediary holding your funds. Every trade settles on-chain in seconds.
Key Features
Fast Execution
Trades are routed and submitted to the relevant chain with minimal latency. You see a price, you confirm, it settles.
Best-Price Routing via Carbium
Every swap goes through Carbium — onchain.cc's internal DEX aggregator. Carbium splits and routes your order across DEX liquidity sources to get you the best available price. You don't configure anything; it works automatically on every trade.
Rank-Based Platform Fee (0.15% → 0.10%)
onchain.cc charges 0.15% per trade at the Recruit rank — the lowest base platform fee in DeFi. Each Colosseum rank reduces your swap fee by 0.01 percentage points, all the way down to 0.10% at Immortal. See Rank System for the full schedule.
Self-Custody
You authenticate via Privy and trade with your own wallet. onchain.cc never holds your tokens. Every transaction is yours to verify on-chain.

What You Need to Trade
A connected self-custody wallet (via Privy)
A small balance of the chain's native token (e.g. SOL on Solana, ETH on Ethereum) for gas fees
The token you want to sell, or the chain's native token if you're buying
Info: Gas fees are paid in the chain's native token (SOL on Solana, ETH on Ethereum, etc.) and are separate from the 0.15% platform fee. Keep a small balance of the native token on whichever chain you're trading on to cover transaction costs.
