Verify it yourself

The only thing you trust the site for is one address per coin: the staking address you send the coin to. You do not have to: it is derived from the coin's mint and public seeds, right here in your browser, with nothing fetched. Redo it below, or without the site at all with the script at the bottom.

Coin mintYour wallet (optional, for your position)

Token-2022 coin (every pump.fun coin created through this site is; untick for a classic SPL coin)

What goes into it

Program: PoSBsxAZVhLmPAUv9YLcWHauVjzSro6smzt92JPWtLY
PDA seeds: ["pool", mint] · ["position", pool, wallet] · ["creator", mint] · ["config"]
Token accounts: Standard associated token addresses (ATA) of the pool PDA, with the coin's token program.
Who says who sent what: The chain cannot tell the program who made a plain transfer, so our crank reads the sender from the transaction and attests it. The program never lets it credit more than the vault holds, and publishes every credit with its origin signature — anyone can re-check them with npm run audit.

Without the site

The program's source is public on GitHub. Anyone can rebuild it and check that the bytes match what runs on Solana:

solana-verify verify-from-repo -u mainnet-beta \
  --program-id PoSBsxAZVhLmPAUv9YLcWHauVjzSro6smzt92JPWtLY \
  https://github.com/proofofstake-fun/pos-protocol --library-name fee_stake

Every address above can be recomputed offline, in any language, with Solana's find_program_address and the seeds above. The docs list every address we operate.
