# How It Works

Here is how to exchange tokens on Talken Swap.

<Steps>
  <Step title="Select Tokens">
    Choose the token to exchange (From) and the token to receive (To). You can swap tokens on the same chain or select tokens on different chains for a cross-chain swap.

    Examples:

    * ETH on Ethereum to USDT on Ethereum (same chain)
    * USDT on Ethereum to JPYC on Polygon (cross-chain)
    * KAIA on Kaia to ETH on Arbitrum (cross-chain)
  </Step>

  <Step title="Enter Amount and Review Quote">
    Enter the amount to exchange, and Talken Swap queries multiple DEXs simultaneously to find the optimal route. The following information is displayed:

    * **Estimated Receive Amount:** The number of tokens you will receive after the swap
    * **Exchange Rate:** The conversion rate between the two tokens
    * **Route:** Which DEX handles the trade (e.g., Uniswap V3, Curve, etc.)
    * **Estimated Fees:** Total of DEX fees, gas fees, and bridge fees (for cross-chain)

    If multiple routes are available, the most favorable one is selected by default. You can also choose a different route.
  </Step>

  <Step title="Execute Swap">
    After confirming the route and fees, execute the swap. Your wallet will request a transaction signature. Once approved, the swap proceeds.

    * **Same-chain swap:** Completes within seconds.
    * **Cross-chain swap:** After the transaction is confirmed on the source chain, tokens are transferred to the destination chain via a bridge. This typically takes a few minutes.
  </Step>

  <Step title="Confirm Completion">
    Once the swap completes, the tokens appear in your wallet. You can check the transaction details in the transaction history. For cross-chain transactions, the progress of each step is shown: source chain, bridge, and destination chain.
  </Step>
</Steps>

### **Gasless Mode**

If you do not hold native tokens (ETH, KAIA, etc.) to pay gas fees, you can enable gasless mode and pay fees in USDT, USDC, or TALK instead. In this case, a relayer submits the transaction on your behalf, and you only need to sign.

### **What Talken Swap Is Not**

* **Not a DEX.** Talken Swap does not operate its own liquidity pools. It is an aggregator that queries existing DEXs such as Curve, Uniswap, and PancakeSwap to find the optimal route.
* **Not a bridge.** For cross-chain transactions, Talken Swap uses verified external bridge protocols such as Circle CCTP and LayerZero. Talken Swap does not relay cross-chain messages itself.
* **Not a custodian.** Talken Swap does not hold user assets. Every transaction requires a wallet signature from the user. Transactions execute through smart contracts, and Talken cannot access user assets.
