What format is required for submitting a transaction?

Transactions must be submitted as a JSON object containing 'to' (address), 'data' (hex string), 'value' (amount in wei), and 'chainId' (numeric).

Which blockchain networks are supported?

The skill currently supports Ethereum (Mainnet), Polygon, Base, and Unichain.

What validation does the skill perform?

The skill validates that the target address is 40 hex characters, the calldata is properly hex-encoded with a 0x prefix, and the chain ID is supported.

Can I use this to send ETH or native tokens?

Yes, set the 'data' field to '0x' and specify the amount you wish to send in the 'value' field using wei units.

Is gas estimation handled automatically?

The skill handles the submission of the transaction payload; however, the user must ensure the associated wallet has sufficient funds for both the value transfer and gas fees.
