Research driving the Privatum product thesis
Four market failures that explain why Privatum uses distributed signing, passkey recovery, and privacy by design.

Common Questions
Privatum combines a desktop client, co-signer service, recovery passkey, Robinhood Chain adapter, and open SDK in one threshold custody architecture.
Yes. The co-signer policy layer can enforce spending limits, velocity controls, session checks, and anomaly detection before a second signature is produced.
The desktop client signs with Shard A, the co-signer signs with Shard B after policy validation, and the partial signatures combine for settlement on Robinhood Chain.
If the desktop shard is lost, the recovery passkey and co-signer can rotate a new client shard without exposing a seed phrase.
No. Privatum holds only the co-signer shard and cannot move funds without the desktop client or recovery passkey.
Privatum is built first for Robinhood Chain, an Ethereum-compatible Layer 2 with ETH gas, ERC-4337 support, and chain ID 4663.
The roadmap moves from custody MVP and SDK launch to swaps, invisible setup, confidential activity, and multichain expansion.
