Why We Recommend Hoseki
Hoseki solves a real problem that Bitcoin holders face when interacting with traditional finance: proving you own Bitcoin without exposing your addresses or giving up custody. The platform uses cryptographic signature verification to generate standardized ownership statements that banks, lenders, and institutions actually accept. New users get 5 free verified statements to start, and the non-custodial design means Hoseki never holds your funds or private keys.
The institutional traction speaks volumes about the platform's credibility. Major players like Bitwise, Metaplanet, Monochrome Bitcoin ETF, and Ledn use Hoseki for proof-of-reserves and real-time transparency. The perpetual monitoring feature continuously verifies attested addresses, preventing double-attestation fraud while maintaining ongoing proof. Support for both single-sig and multisig wallets, plus growing exchange integrations through Hoseki Connect, makes it practical for diverse custody setups.
Best For
Bitcoin holders seeking loans or mortgages will find Hoseki invaluable. Instead of sending screenshots or exposing wallet addresses to lenders, you generate cryptographically verified statements that prove ownership while protecting your privacy. This is particularly useful for Ledn loans and similar Bitcoin-backed lending products where proof of collateral is required.
Institutional treasuries and publicly traded companies benefit significantly from Hoseki's Proof of Reserves tools. Corporate Bitcoin holders like Metaplanet use it for transparent disclosures to shareholders and regulators. ETF issuers like Monochrome and Bitwise leverage the platform for real-time reserve verification that builds investor confidence.
Developers and fintech companies can integrate Hoseki's APIs to add Bitcoin verification capabilities to their own products. The white-label options and wallet connection APIs enable custom solutions for underwriting, compliance workflows, and financial disclosures without building cryptographic verification infrastructure from scratch.

Considerations
Bitcoin-only with no multi-asset support. Exchange integrations are still expanding, so your specific exchange may not be available yet. Address changes trigger a 60-day re-attestation cooldown which could delay urgent verifications.
