Bitpowr

Bitpowr provides digital asset custody and wallet infrastructure for institutions and developers. Clients use a unified API and console to create and manage wallets at scale across 15 public chains covering more than 2000 assets, serving trading venues, fintech firms and digital wallets that need custody, sweeping and settlement functions without assembling them in house. It targets the single point of failure in key management and the separation of compliance, settlement and risk workflows that institutions face when running multi-chain wallets.

For the key layer, Bitpowr combines multi-party computation (MPC) with a cloud hardware security module, splitting and encrypting key shares across separate environments. Custodial wallets sign through a threshold signature (TSS) library while self-custodial wallets reconstruct keys at signing time via secret sharing (SSS); both share one policy engine covering withdrawal limits, approver sets, collection intervals and anti-money-laundering rules, linked to KYT transaction monitoring and KYC verification. It is positioned as a wallet-as-a-service layer for institutions rather than a retail wallet application.
