check_wallet_trustProof of real PnL for a Solana wallet: recomputes REALIZED SOL profit/loss on-chain (not peak scores, which are routinely wrong — 50% of tracked 'smart money' is genuinely losing). Returns verdict TRUSTED/NEUTRAL/UNTRUSTED/INSUFFICIENT/UNVERIFIABLE with confidence, stable reason codes and flags (e.g. known_sniper_bot = real PnL but not replicable by copying). Conservative by design: says UNVERIFIABLE instead of guessing. Use before copy-trading or trusting any wallet.
check_wallet_forensicsWallet forensics: trace a Solana wallet's funding ORIGIN and freshness. Complements the trust check — that says 'is this wallet really profitable?', this says 'where did its money come from, is it fresh or cluster-linked?'. Returns CEX_FUNDED (real end-user), WALLET_FUNDED (possible cluster/Sybil), UNKNOWN_ORIGIN, UNVERIFIABLE_ORIGIN, plus a fresh_wallet flag (elevated insider/bundle risk). Use alongside check_wallet_trust before copy-trading.
check_trade_costExecution cost oracle: what will this trade REALLY cost? Expected slippage for YOUR size in the token's main pool, round-trip cost estimate calibrated with measured real-world execution overhead (latency, priority fees, drift — textbook AMM math underestimates live costs), and a recommended max size. Use before EVERY trade. Verdicts: ACCEPTABLE_COST/ELEVATED_COST/HIGH_COST/UNTRADEABLE/NO_POOL/UNKNOWN.
check_token_safetyStructural risk check for a Solana token: real-holder concentration (bonding-curve/LP correctly excluded), known sniper bots among early buyers, honeypot round-trip. Returns verdict LOW_RISK/ELEVATED/HIGH_RISK/CRITICAL with stable reason codes. Honest scope: flags structural red flags with zero noise; behavioral dumps (operator sells into own facade) are invisible to ALL structural checkers — for those, check the wallets involved instead.
