Is $Json a rug?
MASTRscan gives no verdicts, it shows what the chain shows: Critical risk level, 13 of 22 checks passed. On the questions a rug turns on: the price shows no collapse in the last 24 hours (no collapse in 24 h); liquidity changed +80.3% in the last hour; a real sell quote found a route (price impact 2.99% on $500); top 10 hold 76.3%; mint authority revoked; freeze authority none. A rug is when the people behind Json pull the liquidity or sell the supply they hold; nothing here can promise that it will not happen. Read 2026-09-29 09:19 UTC. Not financial advice.
