Validating Lightning Signer is an open-source Rust SDK and reference implementation that separates a Bitcoin Lightning node from a remote signer holding private keys, so a compromised node cannot steal funds. Validating Lightning Signer's Twitter Score is 9.1 out of 1000 as of October 2026, ranking #102,482 among 497,670 tracked accounts.
Validating Lightning Signer was founded by Ken Sedgwick and Dev Random. The project works by keeping signing keys off the node entirely, with the remote signer independently validating state changes and operator policies before countersigning any transaction. This architecture supports multiple signing devices for a single Lightning node through a tag-team signing feature, and the library is released under the Apache license as a developer tool rather than a consumer wallet.
Validating Lightning Signer has backing from OpenSats, Spiral, the Human Rights Foundation Bitcoin Development Fund, and Blockstream. Blockstream's Greenlight signer is built on VLS to keep signing keys under user control while enabling end-to-end verification, and Blockstream reported a USD $150,000 grant for that integration work. Validating Lightning Signer is also affiliated with Core Lightning and Lightning Development Kit, and the project published a technical analysis of a Core Lightning remote-signer channel-state synchronization issue in June 2026.
Validating Lightning Signer released version 0.14.0 on November 7, 2025, adding BOLT12 signing support, expanded HTLC-output monitoring, automatic database migration, and dependency security updates. That release recommended testnet use or limited production funds until a planned production-release milestone, noting it did not yet cover every possible fund-loss scenario. Validating Lightning Signer has published 863 posts on the platform. The account has been mentioned by 12 accounts, with 20 total mentions.
