Not your keys, not your coins is more than a slogan — it is a design constraint. HodlHodl is one of the few exchanges in the world that has taken that constraint seriously from day one. Founded in 2016 by Max Keidun and based in Riga, the platform allows users to buy, sell, and lend Bitcoin peer-to-peer using multisig escrow, with the company itself never touching customer funds.

The product line covers the two activities most prone to custodial failure: spot trading and lending. On HodlHodl's marketplace, counterparties agree on price and payment method while their Bitcoin sits in a 2-of-3 multisig contract. With Lend, borrowers post Bitcoin collateral into the same multisig structure to access stablecoin or fiat liquidity, never surrendering their keys to a third party.

This fits squarely with the Fulgur thesis. Every cycle of centralized exchange collapses — from Mt. Gox to FTX to Celsius — has confirmed the same lesson: custody is the single point of failure. HodlHodl is building the alternative rails. By pairing self-custody with a usable trading and lending experience, it shows that non-custodial finance can be a real product, not just a principle.

The bigger picture matters even more. As regulatory pressure on centralized intermediaries intensifies and as Bitcoin moves into adoption phases driven by sovereignty rather than speculation, demand for permissionless, non-KYC-by-default infrastructure will keep growing. HodlHodl has been quietly building that infrastructure for nearly a decade.

We partnered with HodlHodl in 2020 because we believe peer-to-peer markets, anchored by Bitcoin's own security model, are the long-term shape of free trade online — and Max and his team are among the very few who have been building that future without compromise.
