How it works

Built on Cosmos Hub transactions

Asteroid Protocol uses the memo field and transaction data of Cosmos Hub (ATOM) transactions to permanently store data on-chain.

Connect your wallet
Connect a Cosmos-compatible wallet like Keplr or Cosmostation. You'll need a small amount of ATOM for transaction fees.
Choose what to inscribe
Upload an image, video, text file, or configure a new CFT-20 token. The content is encoded and embedded in your transaction.
Sign the transaction
Sign the transaction in your wallet. A small ATOM fee pays Cosmos Hub validators to process and permanently store your inscription.
It's on-chain forever
Your inscription is now part of the Cosmos Hub blockchain. It will exist as long as the network runs — no servers required.
