BlockSafe Technologies has developed three products - CryptoDefender, ExchangeDefender, and BlockchainDefender - to secure cryptocurrency wallets, exchanges, and permissioned blockchains from hackers. They are launching a Security Token Offering to raise up to $27 million through the sale of BSAFETM tokens. Token holders will receive 10% of the company's revenue in passive income. The funds will be used for research and development, marketing, operations, and legal/insurance costs as the company expands its team and products.
