Check for Padding Outputs

An API Key is required to interact with Launchpad APIs. Please contact us to get an API Key and get started.

This endpoint helps you find out if the buyer's payment address has the necessary extra outputs, called "padding outputs" in their UTXO set. These extra outputs are used for setting up a buying transaction safely. They are part of a special security method called the 2-Dummy UTXO algorithm. This technique makes sure the Ordinal stays safe and isn't mixed up with other less important or dummy outputs. It also prevents the Ordinal from being mistakenly used up in transaction fees. The system follows common rules, creating a UTXO for the NFT at a specific starting point and setting aside 10,000 satoshis (sats) as postage. This careful approach keeps the transaction secure. This end point is to check if there are padding UTXOs available in the buyers UTXO set. If these are not then https://testnet-api.ordinalsbot.com/launchpad/setup-padding-ouputs can be used to create padding outputs.
