What Wizardsardine does

Wizardsardine is a Bitcoin self-custody technology company founded in 2020 in the Azores, Portugal, by CEO Kevin Loaec and co-founder Antoine Poinsot. The company builds open-source Bitcoin custody infrastructure, with its flagship product being Liana, a self-custody wallet constructed on Miniscript and timelock-based recovery mechanisms (marketed as the Safety Net feature). The portfolio spans Liana (open-source consumer wallet), Liana Business (enterprise tier priced at 0.016% of AUM per month, launched November 2025), and Revault (prototype). The team is small (1-10 employees), concentrated in Portugal, with founders who contribute to Bitcoin Core and Bitcoin standards work including BIP 388.

The technical stack centers on Miniscript for policy-based spending conditions and timelocks for delayed recovery paths, differentiating Liana from standard single-key and conventional multisig wallets. The wallet is compatible across the major hardware-wallet vendors (Coldcard, Ledger, BitBox, Jade, Krux, Specter DIY), and the September 2024 v7.0 release added Liana Connect, a connectivity layer for external service interaction. In December 2025 the company partnered with Resolvr BDIC to offer Bitcoin-denominated insurance coverage to Liana users, extending the product surface from software into risk transfer.

Wizardsardine monetizes primarily through enterprise subscriptions tied to assets under management via Liana Business, while distributing the core wallet as open-source software to individual users and the developer community. Go-to-market combines direct sales to institutional and grant-giving customers with a Certified Partners channel (launched July 2024) currently active in the Netherlands, Argentina, and Brazil. The company has been capital-efficient to date, raising only a pre-seed round in August 2020 and a bridge round in January 2022, with no disclosed revenue or customer-count metrics in the available material.

Core offering

Wizardsardine builds and sells Bitcoin self-custody software and infrastructure. Its flagship product, the Liana wallet, uses Miniscript and on-chain timelocks to let users define primary spending paths plus time-delayed recovery paths for inheritance, key loss, and disaster recovery. The free Liana Community Edition is open-source and runs against the user's own node, while Liana Business adds hosted infrastructure, SLAs, APIs, PSBT coordination, web dashboards, and optional Bitcoin-denominated insurance for organizations and HNWIs.

Product overview

Wizardsardine is a Bitcoin security company offering a portfolio of products centered on self-custody solutions. The core product is Liana, a Bitcoin wallet built on Miniscript and timelocks that provides time-based recovery options. Liana is available in two tiers: the free Community Edition for individual users, and Liana Business for organizations requiring hosted infrastructure, professional support, and enterprise features. Revault is an advanced vault architecture for large organizations (currently on hold). The company also offers security services including architecture audits, vulnerability disclosures, and operational security assessments. Safety Net, a third-party key agent recovery service, provides an optional additional layer of protection.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• Nunchuk Wallet: Nunchuk is an open-source Bitcoin multisig wallet focused on collaborative custody for individuals and teams. Like Liana, it emphasizes user-controlled keys, descriptor-based setups, and institutional-style policy controls.
• Unchained Capital: Unchained Capital is a Bitcoin-native collaborative custody provider offering multi-institution multisig vaults for individuals and businesses. It is the closest direct competitor to Liana Business, with a similar focus on self-sovereign key control and institutional treasury use cases.
• Casa: Casa offers multisig Bitcoin self-custody subscriptions for individuals and families, with a paid premium tier. Casa competes directly with Liana's Community/individual tier on multi-key recovery, key agent services, and inheritance.

Emerging players

• Coinkite (Coldcard): Coinkite makes Coldcard hardware wallets, including the SSSP refresh-only feature used by Liana. It is a complementary hardware signer vendor rather than a custody competitor, but is comparable as a Bitcoin-only security specialist.
• Sparrow Wallet: Sparrow is a desktop Bitcoin wallet for power users that emphasizes multi-sig, descriptor-based setups, and self-custody. It overlaps with Liana Community Edition on the technical individual/HNWI user segment.
• Blockstream: Blockstream builds Bitcoin infrastructure including the Jade hardware wallet that integrates with Liana. It is an adjacent player with overlapping Bitcoin ecosystem influence rather than a direct custody competitor.
• Revolut Crypto / Swan Bitcoin: Swan Bitcoin is a Bitcoin-focused financial services platform offering IRAs, treasury services, and self-custody tooling for individuals and businesses. It is an emerging player in the same Bitcoin-only financial-services niche as Wizardsardine, though more retail-brokerage oriented.

Broad incumbents

• Anchorage Digital: Anchorage is a federally chartered digital asset bank offering qualified custody for institutions, including Bitcoin. It competes for the same enterprise Bitcoin treasury segment that Liana Business targets, but via qualified rather than self-custody.
• BitGo: BitGo provides institutional digital asset custody and wallet infrastructure, including Bitcoin cold storage and multi-sig products. It is a broad incumbent serving banks, hedge funds, and corporates that Liana Business is also pursuing.
• Coinbase Custody: Coinbase Custody is a large-scale qualified custodian offering Bitcoin and other digital asset storage for institutions. It represents the regulated-custody alternative to Liana Business's self-custody pitch for corporate treasuries.
