| SolEnrich Finds fresh Solana memecoins whose on-chain buying is accelerating — the signature of a run in progress, not the lagging fact that price already moved.

Classifies RUNNING / IGNITING / PARABOLIC_LATE / FADING with a 0-1 score plus reasoning. Flags wash-trade smell and liquidity pulls rather than dressing them up as momentum. | solenrich.com | - | $40,000.00 | listed |

This reconstructs a wallet's ACTIVE spend permissions from onchain approve/revoke events and flags the dangerous ones: unlimited allowance, no expiry, unrecognized spender.
