# Swaps & Bridges

> Execute token swaps and cross-chain bridges through conversation. LI.FI routing across 35+ chains with inline execution panels.

# Swaps and bridges

Ask any DeFAI agent to swap tokens or bridge assets, and it prepares an inline execution panel. Routing is handled by **LI.FI**, which aggregates DEX liquidity across 35+ chains to find the optimal path.

## How to use

* `"Swap 100 USDC to ETH on Base"`
* `"Bridge 500 USDC from Ethereum to Base"`
* `"How much ETH can I get for 1000 USDC?"`

## Swap flow

<Steps>
  <Step title="Agent prepares quote">
    The agent queries LI.FI for the best route, considering slippage, gas costs, and liquidity depth. The result renders as a **DefiSwapQuotePanel** or **SwapExecuteInline**.
  </Step>

  <Step title="Quote panel displays">
    Depending on the response, you see:

    * **Full quote**: From token → To token with amounts, price impact, gas estimate, route details
    * **Token price**: Quick price lookup
    * **Available tokens**: List of tradeable tokens on the selected chain
    * **Suggestions**: Clickable suggestion chips for follow-up actions
  </Step>

  <Step title="Confirm execution">
    The **SwapExecuteInline** panel shows:

    * Token icons and symbols for from/to
    * Exact amounts
    * Price impact percentage
    * Gas estimate
    * Route path

    Click **Confirm** to execute.
  </Step>

  <Step title="Multi-step progress">
    The execution follows these steps:

    1. **Check** — verify balance and network
    2. **Approve** — token approval signature (if needed)
    3. **Execute** — swap transaction
    4. **Done** — completion with transaction hash

    Each step shows a checkmark (complete), spinner (in progress), or dimmed (pending). The transaction hash links to the block explorer.
  </Step>

  <Step title="Feedback message">
    On success or failure, the agent automatically sends a feedback message to the chat confirming the outcome. Wallet data is refetched to update balances.
  </Step>
</Steps>

## Cross-chain bridges

Cross-chain transfers use the same flow but with Circle CCTP or LI.FI bridge routes:

* **Circle CCTP**: USDC transfers between Base ↔ Ethereum ↔ Polygon ↔ Arbitrum. Native USDC bridging with no wrapped tokens.
* **LI.FI**: Aggregated bridge routes across 35+ chains for any supported token.

The inline panel shows the source chain, destination chain, and estimated transfer time.

## Supported chains

| Chain                  | Network               |
| ---------------------- | --------------------- |
| **Base**               | Primary (wallet home) |
| **Ethereum**           | Mainnet               |
| **Polygon**            | PoS chain             |
| **Arbitrum**           | L2                    |
| **Optimism**           | L2                    |
| And 30+ more via LI.FI |                       |

<Tip>
  For USDC transfers between major chains, Circle CCTP is the most efficient route — native USDC with no wrapped intermediaries. LI.FI automatically selects the best route, but you can specify "bridge via Circle" if you prefer.
