Transaction simulation and fraud prevention for Solana wallets

Overview

Blowfish is a transaction simulation and fraud prevention platform for Solana and other blockchains that helps wallets, dApps, and users understand what will happen before they sign a transaction. It serves as a critical security layer that protects users from scams, phishing, and malicious smart contract interactions. When a user initiates a transaction, Blowfish simulates its execution and provides a human-readable preview of the outcome — showing exactly which tokens will be sent, received, or approved, and flagging any suspicious patterns. This simulation catches common attack vectors including approval phishing, drainer contracts, malicious token interactions, and hidden function calls that could drain user wallets. Blowfish integrates with major wallets and platforms as a backend security service. When Phantom or other wallets show a transaction simulation preview, the data often comes from Blowfish's simulation engine. This behind-the-scenes role means Blowfish protects millions of users even if they've never heard the name, providing security infrastructure for the ecosystem's most-used applications. The platform also provides a developer API for applications that want to add transaction simulation to their own interfaces. The API supports both EVM and Solana transactions, making it useful for multi-chain applications. Blowfish has prevented hundreds of millions of dollars in potential fraud, making it one of the most impactful security tools in the Solana ecosystem.

We have big news – Blowfish has been acquired by @Phantom! As we move into this new chapter, we want to reflect on our journey and express our heartfelt gratitude to all of you. 💙 Over the past few years, we’ve been honored to earn the trust of 40+ wallet partners, helping protect $18B+ in user assets from scams. Together with @Phantom, @krakenfx, @MetaMask, @brave, and others, we pioneered B2B crypto scam prevention and made real strides toward a safer web3. Joining forces with Phantom, a secure, self-custodial wallet, is the next step in our journey. Being part of a company that values user security as much as we do will allow us to deepen our integrations into the wallet and offer users even better security. We’re already working on it! Our team is rolling out new safety features for Phantom as we speak – from intuitive transaction previews to real-time fraud insights – setting new standards in crypto security. Together, we’ll help millions explore web3 with confidence. To our customers, partners, and friends: thank you for trusting us. While the Blowfish brand is going away, our mission remains the same. We’re excited to embark on this new journey with Phantom and can’t wait for what’s ahead. Here’s to a safer crypto future! 🥂🔒 The Blowfish team
