Price: 0.020000 USD per call (paid via MPP on Tempo)

What it checks

Freeze authority revoked or active (active = can freeze holders)
Mint authority revoked or active (active = supply inflatable)
Token program (SPL vs Token-2022)
Metadata update authority
Top-holder concentration

On-chain heuristic only. A GO means mint and freeze authorities are revoked and no other on-chain red flags were found, not that the token is safe. Does not parse Raydium/Pump.fun liquidity or detect honeypots. Never the sole basis for a trade.
