Can I use this for cross-chain bridges?

Yes, it supports the swapCrossChain transaction type, allowing you to move assets between supported networks like Ethereum and Base.

Does this skill execute the transaction for me?

No, the skill generates the encoded transaction data and metadata. You must sign and broadcast the transaction using your own wallet client or private key.

How do I validate the transaction data before signing?

The skill returns a TransactionMetadata object containing human-readable details, chain IDs, and recipient addresses that you should verify before execution.

Is there a cost to generate these transactions?

Each query via the SDK costs $0.01 USDC through the x402 micropayment system, which is separate from the gas fees required to execute the transaction on-chain.

What blockchain networks are supported?

The skill supports major EVM-compatible chains including Ethereum, Base, Polygon, and others integrated within the Bankr infrastructure.
