Bitcoin (BTC) Dev Paul Sztorc Claims 80% of Lightning Payments Are Custodial

Bitcoin (BTC) developer Paul Sztorc has reopened a long-running dispute over the Lightning Network, claiming that 80% of payments on the network are custodial and that the Bitcoin community has been "lying to itself" about how its payments layer actually works.

The figure is a claim about how the network is used in practice rather than how the protocol is designed: Lightning is built to support self-custodial channels, and Sztorc's assertion addresses the share of real-world payments that instead pass through intermediaries.

In an October 4 post on X, Sztorc wrote that "most people don't realize how bad the Lightning…", as quoted in an excerpt published by COINOTAG. The assertion touches on a central design goal of the technology: enabling users to transact off-chain while retaining direct control over their own funds. If the 80% figure is accurate, it would mean that most Lightning payments involve a third party holding channel funds, a model that sits at odds with that stated goal for the users involved.

Background: What the Lightning Network Is

The Lightning Network is a layer-2 payments protocol built on top of Bitcoin. First described in a 2016 whitepaper by Joseph Poon and Thaddeus Dryja, it routes payments across a mesh of off-chain payment channels, allowing transactions to settle in seconds at low cost while easing congestion on the Bitcoin base layer. In a self-custodial setup, users commit their own funds to channels and hold the keys that control them.

Custodial Versus Self-Custodial Payments

Custodial arrangements work differently: an intermediary, typically a wallet provider or service operator, holds and manages channel funds on behalf of users. In that model, users rely on the operator rather than on their own keys, meaning the safety of those funds rests with the service's handling rather than with the user's own key management. It is this distinction that underlies Sztorc's claim that the majority of Lightning payments are custodial rather than direct, user-to-user transfers. It is also why the custody split matters: the larger the custodial share, the further everyday usage sits from the self-custodial model the technology was designed around.

Who Is Paul Sztorc?

Sztorc is a longtime Bitcoin developer known for the Truthcoin peer-to-peer prediction-market design and as the author of the Drivechain proposals (BIP-300, BIP-301, and BIP-302), which would allow Bitcoin sidechains to be anchored to and secured by the main blockchain. He has been an outspoken critic of the Lightning Network's architecture, and his October 4 post marks the latest round in that dispute. For readers following the story, the next things to watch are any supporting data behind the 80% figure and any response from the Lightning developers and wallet providers whose custody practices the claim touches.
