| UniswapClassic | The widely adopted Uniswap v2/v3/v4 architecture accessed through the Universal Router. It provides deterministic, on-chain execution with deep liquidity across many ecosystems                                                                                                 | Ethereum Mainnet, BNB Smart Chain, Polygon, zkSync, Base, Arbitrum, Celo, Avalanche, Worldchain, etc.  <br />  <br />Check the full list [here](https://api-docs.uniswap.org/guides/supported_chains) |
| UniswapX       | The latest version of Uniswap's swap protocol focused on efficient routing, improved UX, and better rates.                                                                                                                                                                       | Ethereum Mainnet, Arbitrum, Base and Unichain  <br />  <br />Check the full list [here](https://api-docs.uniswap.org/guides/supported_chains)                                                         |
| CircleCctp     | Cross-chain USDC transfer using Circle's [Cross-Chain Transfer Protocol](https://www.circle.com/cross-chain-transfer-protocol). USDC is burned on the source chain and minted on the destination chain. Both the input and output asset must be USDC, on **different** networks. | Ethereum, Optimism, Arbitrum, Base, and Solana (Fast and Standard transfer)  <br />  <br />Avalanche and Polygon (Standard transfer only)                                                             |

<Note>
  **Single-chain swaps (Uniswap)** execute on one EVM chain: the input and output token are on the same network. DFNS does not integrate other DEX aggregators (0x, 1inch, Jupiter, LI.FI, Squid, and so on).

  **Cross-chain USDC (Circle CCTP)** is the exception: it moves USDC between supported chains using Circle's burn-and-mint protocol. Both the source and destination asset must be USDC. To move any other token across chains, build the bridge transaction yourself and submit it via [Sign & Broadcast](/api-reference/wallets/sign-and-broadcast-transaction). See the [FAQ](/faq) entry on swapping and cross-chain transfers.
</Note>

<Note>
  CircleCctp must be enabled for your organization, and you must accept the CCTP agreement before your first swap. CCTP has no price slippage; instead of `slippageBps` you set `feeToleranceBps` — the maximum bridge/forwarding fee you will accept, in basis points of the amount. Choose `Fast` or `Standard` transfer speed (Fast is not available on Avalanche or Polygon).
</Note>

## How It Works

1. **Select Tokens:** Choose the token you want to swap and the token you want to receive.
2. **Enter Amount:** Specify how much you want to swap.
3. **Review Quote:** Instantly see the best available price, estimated fees, and minimum received.
4. **Set Slippage (Optional):** Adjust your slippage tolerance for added control.
5. **Confirm Swap:** Review all details and confirm your transaction.
6. **Track Status:** Monitor your swap in real time and view your transaction history at any time.

<Note>
  If you have a `Wallet:Sign` policy enabled, you will be asked for up to 4 policy approvals (depending on the asset being swapped). Make sure to approve the requests in less than 30 minutes for Uniswap Classic and less than 5 minutes for UniswapX; otherwise, the Swap will expire and fail.
