Lightning has a Security Problem
Current approaches leave your funds vulnerable and create regulatory headaches
Hot Wallets Vulnerable
Lightning nodes store private keys directly in the node, making them vulnerable to exploits, hacks, and misconfigurations. One breach means total fund loss.
Blind Signers 👎
Blind signers separate keys but sign any request without validation, making them even more dangerous than standard nodes. Now you have two attack vectors instead of one.
Regulatory Burden
Custodial solutions face heavy compliance requirements, limiting your ability to scale and enter new markets. Regulatory overhead slows innovation.
