Our data now leaves a receipt on public blockchains. Every 5 minutes, 35 feeds we compute (funding, open interest, liquidations, order book depth, premiums and pressure scores for $BTC, $ETH, $SOL and more) are sealed into one Merkle root, signed by an isolated key and written to Solana mainnet, with a daily attestation on Base. If anyone, including us, changed one of those numbers afterwards, it would stop matching the chain. You do not have to take our word for it: the verifier on our proof page rebuilds a record, checks its signature and reads the anchor straight from Solana in your own browser. Beta, on mainnet since 18 September. Free, no account needed.
