Institutions now hold 4% of all mined bitcoin. But holding bitcoin at scale isn't about storage – it's about key management and the infra needed to do it securely, without giving up control. 🧵

2/ Bitcoin is controlled by private keys. Lose the key, lose the funds. But managing keys manually (with seed phrases, hardware wallets, signers etc) breaks down at institutional scale. You get security gaps, fragmented controls & no visibility. It’s not infra, it’s exposure.

3/ Institutions need infrastructure that eliminates single points of failure without giving up control.

4/ Turnkey provides non-custodial infra that uses Trusted Execution Environment (TEE) technology to isolate and protect private keys. Private keys are never exposed outside the enclave, not even to Turnkey.

5/ Access is enforced by hardware-backed isolation and strong authentication. There’s no external access or hidden assumptions – institutions retain full control at all times.
