How registration works
02
Pay once, on-chain
A single Solana transaction to the registry treasury, stamped with your reservation reference in the memo. Signed by your wallet; funds go straight to the registry treasury.
03
Own it outright
We verify the payment against the settled on-chain balance before recording ownership. No renewals, no expiry, no annual invoice.
Using your domain
Any app can resolve a .fun domain to its address with a single request. No authentication and no SDK required.

Common questions
What am I actually buying?
A permanent record in the .fun registry that maps your domain to a Solana address you control. You can repoint it or transfer it at any time by signing with the owner wallet.
Are there renewal fees?
No. Registration is a single payment and the domain does not expire. There is nothing to renew and no way to lose it through inaction.
How is payment verified?
The server reads the transaction from a mainnet RPC and checks the treasury's settled balance change, the memo reference, and the signing wallet before recording ownership.
