In the news
- CrypDefi is now Fortkey. Same company, same product, same legal entity (CrypDefi BV). What changes is the name and the look. CrypDefi began in 2024. Since then, the product has become sharply defined: self-custody execution infrastructure for trading firms that measure their edge in microseconds. Fortkey says exactly that. Fortified keys, built for speed. Your wallets, policies, integrations, contracts, and certifications are untouched. Our website is now fortkey.io. Everything that changes and everything that does not:
- CrypDefi is now integrated with Bunker by Station70. In an environment where lost keys mean permanent loss, our customers can now improve their disaster recovery: their teams back up their keys to a Station70 offsite encrypted backup, directly through CrypDefi. What makes Station70 stand out: • Attestation reports with timestamped proof of recovery • Cryptographic verification of key backups • Zero-trust recovery architecture with a full audit trail Recovery infrastructure is not optional for teams operating at
- Most crypto custody rests on a borrowed assumption: that the safest asset is one that sits still. That logic comes straight from traditional finance, where the custodian's job is to keep things from moving. A market maker's inventory is the opposite. It is working capital, quoted and filled and rebalanced continuously, and a custody stack built to slow things down quietly taxes every one of those moves. However fast the venue is, you are never faster than your own signing. Our recent piece works through what self-custody
- We just published a new piece on the CrypDefi Insights page: when self-custody actually pays off for market makers. The short version: A growing share of trading is moving to venues where you hold your own keys by default. DEX spot share has roughly doubled in two years, and #Hyperliquid alone cleared $227 billion in perp volume last month. On-chain, the custody question changes shape. The counterparty claim disappears, and the risk moves to execution: smart contract exploits, oracle failures, and the speed of your own #signing.
