"VLS allowed Greenlight to be developed at breakneck speed, without the risk. It is the fundamental building block, and central to the non-custodial nature of Greenlight." @Snyke

CASE STUDY: How @BlksGreenlight built a secure, non-custodial solution with VLS. Greenlight hosts the Lightning node while end users retain full custody of their signing keys—preserving Bitcoin's principles while providing enterprise-grade security. vls.tech/posts/greenlig…



Without validation, your Lightning wallet is like a bouncer who lets anyone into the club just because they asked. Your funds are still at risk.


Non-custodial isn’t about where the keys are stored. It’s about who has the final say. Without VLS, that’s not you.


A real non-custodial wallet should say “no” when someone tries to steal from you. Blind signing wallets say “yes” every time.


Calling blind signing “self-custodial” is like a bank saying “you’re in control” while they can still move money out whenever they want.


True self-custody means your wallet protects you even if the software running it goes bad. Without validation, it’s just hope, not security.


If your wallet will approve any request without checking, it’s not really yours. That’s not self-custody, that’s shared custody with the attacker.


Hot take: Self-custodial isn’t real unless the signer validates. Thoughts?


What comes to mind when you hear “blind signing"?


Regulators love companies that can demonstrate strong controls. Showing you validate every Lightning signature is a faster way to pass audits and land deals.


Lightning’s biggest bottleneck isn’t speed. It’s custody. Companies that hold user keys can’t expand freely. Truly self-custodial infrastructure clears the path.


You scale Lightning balances when you stop worrying about them disappearing.


“Don’t trust, verify” Yes, even your own Lightning node. And yes, even that Lightning wallet you use that claims to be "self-custodial". Is it really? or is it self-custody larping?


Custody burdens = licenses, audits, legal costs. Self-custody = shipping faster.


Validation + separation = security.


Without validation, your signer will happily approve a revoked state that drains the channel. With validation, that can’t happen. That’s the difference between VLS and blind signing.


You can either fight regulators to be a custodian or outpace competitors by being non-custodial. One is paperwork. The other is progress.


Custody compliance isn’t optional, regulators enforce it. Self-custody isn’t a loophole, it’s the intended design of Bitcoin.


Every Lightning exploit starts with blind trust in the node. VLS removes that trust by independently checking protocol rules before every signature.


Your business doesn’t want to be a bank. VLS makes sure it doesn’t have to be.


One validation engine. 50+ policies. Infinite peace of mind. Priceless. But also free.
