# Transaction In order to register the stake pool, the previously created certificates need to be submitted to the blockchain with a transaction. For that, you will need to already run a node on the blockchain, and you will also need to have some funds available to fulfill the declared pledge, to pay for the stake pool deposit (500 ADA), for the stake key registration deposit (2 ADA) and the transaction fees (less than 0.2 ADA), as also stated on the first page of this guide. On the same page there are also instructions on how to get funds from the faucet for the testnets (preprod and preview). For mainnet, ADA must be acquired, usually from an exchange. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
