Check a round.
Every round with money on it is drawn on Solana. This page reads the round straight from Solana, in your browser, not from our server, and checks it step by step.

What the checks rely on
Steps 5 and 6 read the program’s own receipt in the reveal transaction: Solana keeps a block’s hash for only a few minutes, so the program writes it down when it draws the number. The checks show that the program did what its published rules say. The program can still be upgraded with the owner’s key: see Upgrades.
Check it without this page
- On Solana’s explorer. Every step of a check links to the Solana transaction it reads.
- On your own computer. Download verify-round.py and run
python3 verify-round.py <round address>. Nothing to install: it talks only to Solana, and it is short enough to read first. - By hand. The formula and a short example are on the Solana page.
