BeforeYouSign
A one-tap pre-flight check on any Solana contract or transaction — tells you in plain language whether to sign before you risk real SOL.
everyday Solana wallet users approving transactions they don't fully understand
- Paste a contract address or scan a wallet request for a plain-English risk summary
- Surfaces program age, upgrade authority status, audit history, and owner concentration
- Detects common drainer patterns (suspicious CPI chains, fresh upgradeable owners)
- Optional browser-extension or wallet-connect pop-up that warns you before signing
The article details exactly how irreversible and easy to mess up Solana deploys are — the same risk hits users on the other side of those deploys, who routinely approve transactions for contracts with no upgrade-authority check, no audit, and a wallet-based owner. With constant new program launches, everyday users need a consumer-grade safety net.
Documented losses: $4M drained from 4,000 Solana victims in Feb 2024 (Scam Sniffer), $2B total crypto scam losses in 2024 (Chainalysis), real case of 35 SOL lost in one signature — pain is real but mainstream wallets (Phantom, Solflare) already ship built-in simulation/warnings.Solana Users Targeted by Widespread 'Wallet Drainer' Phishing Campaign ↗How Solana Wallet Drain Scams Actually Work | Hodder Law ↗
Crowded market: Blowfish (Solana-supporting API), Pocket Universe, Wallet Guard, Fire, ShieldFi (free Solana scanner), cryptomathtools.com safety checker, cryptoaml.ai AML checker, plus Phantom/Solflare wallet-level simulation — direct, well-funded competitors already serve this exact need.Blowfish - Proactive defense for web3 wallets ↗Free Solana Wallet Scanner | Check for Scams & Fake Tokens | ShieldFi ↗
Most competitors are free (ShieldFi, cryptomathtools) or sell B2B APIs to wallets (Blowfish's pricing model). End-consumer willingness to pay is unproven — most users rely on free wallet-level warnings, and the hook comes bundled with the wallet itself.Blowfish — Security / Audit · web3.new ↗Solana Wallet Safety Checker — Check Wallet Safety Before You Send ↗
Wallet drainer kits evolve continuously and the underlying risk of irreversible transaction signing is permanent — but wallet providers keep absorbing more of this functionality natively, which could squeeze a standalone consumer tool over time.7 Solana Scams Every Wallet Owner Must Know (2025 Edition) ↗
Buildable by combining Solana RPC for on-chain facts, audit registries for audit/upgrade-authority checks, and LLM summarization for plain-language output — but a published Coinspect case study shows transaction simulation itself is hard and can produce false confidence, raising the bar.Unveiling Transaction Simulation Challenges: Blowfish Case Study ↗
