Luganodes x Starknet: Federation Signer for Private Bitcoin on Starknet

Introduction

Luganodes is proud to announce its role as a Federation Signer for strkBTC, the first Bitcoin wrapper on Starknet with native privacy. As one of five independent institutions in the strkBTC Federation, Luganodes will operate the infrastructure that supports the minting, burning, and bridging of BTC and strkBTC between Bitcoin and the Starknet ecosystem, without custody of user assets.

The strkBTC Federation

Bringing Bitcoin onto a Layer 2 without compromising its core security properties is one of the hardest problems in the ecosystem. The approach Starknet has taken starts with an explicit Federation of five independent signers: Twinstake, NEAR Intents, Luganodes, UTXO, and Xverse. Each Federation member operates infrastructure that supports BTC movement in accordance with protocol rules. The trust model is clear and bounded, operated by known independent entities with defined roles and transparent participation.

This federated model provides a practical foundation: a clear security perimeter defined by the composition and reputation of the Federation itself. The trust assumptions are explicit rather than obscured, making it auditable from day one.

About Starknet

Starknet is a Validity Rollup developed by StarkWare that uses STARK proofs to scale Ethereum while retaining its security guarantees. It features native account abstraction, where all accounts are smart contracts, giving developers and users flexibility that protocol-level constraints would otherwise prevent.

Beyond Ethereum scaling, Starknet is building toward becoming Bitcoin's execution layer. The network has shipped native BTC staking, introduced strkBTC as the first wrapped Bitcoin asset on Starknet redeemable for native BTC with optional shielding for private balances and transactions, and launched Asset Runes, Bitcoin-native tokens backed 1

by reserves on Starknet.

Luganodes x Starknet

As a Federation Signer, Luganodes joins the group of independent institutions that underpin strkBTC, co-signing bridging events and helping maintain the integrity of Bitcoin locked and minted across chains. This role places Luganodes directly in the critical path of Bitcoin moving onto Starknet, and by extension, in the infrastructure layer that makes private Bitcoin transactions possible. Infrastructure reliability and security posture are the defining factors of what Luganodes brings to the collaboration.

Luganodes brings institutional-grade, non-custodial infrastructure to a role where the consequences of failure are financial losses for bridge users. The Federation model demands signers whose operations can be audited and held accountable, and that is precisely the profile Luganodes is built for.

Conclusion

The Federation is not the end state for strkBTC. The roadmap progressively hardens: Phase 2 adds Bitcoin-native verification with post-quantum security, Phase 3 introduces a trust-minimized BitVM, and Phase 4 arrives at a fully trustless OP_CAT design. This collaboration reflects Luganodes' commitment to supporting the infrastructure layer of emerging Bitcoin finance at every stage of that journey.
