Tool Name	Schema	Purpose	Input Fields
swap_tokens	swapTokensToolSchema	Swap tokens across different chains using XCM or within a specific DEX	amount, currencyFrom, currencyTo, from (optional for cross-chain), to (optional for cross-chain), dex (optional for DEX-specific), receiver (optional)

Integration

The DeFi swap features are available out-of-the-box via the Polkadot Agent Kit's tools:

• swapTokensTool()

---

Usage

Cross-Chain Swap

Prompt:

await agent.prompt("swap 1 DOT from Polkadot to USDT on Hydra")

DEX-Specific Swap

Prompt:

await agent.prompt("swap 0.5 DOT to USDT on HydrationDex")

Replace values like amounts, currencies, chains, and DEX names as needed.

How It Works

• Cross-Chain Swap:

  • The Agent uses the swapTokensTool() from the Polkadot Agent Kit.
  • It parses your message for amount, currencyFrom, currencyTo, from chain, to chain, and optional receiver.
  • Executes the swap across chains using XCM routing.

• DEX-Specific Swap:

  • The Agent uses the same swapTokensTool() but omits from/to chains.
  • Parses for amount, currencyFrom, currencyTo, dex (defaults to HydrationDex), and optional receiver.
  • Executes the swap within the specified DEX.

Example Code
