Managed wallets

A managed wallet is an EVM wallet where Prudra generates and custodies the private key. The key is protected using envelope encryption — it never exists in plaintext outside hardware. You provision a wallet, receive an address, fund it, and Prudra can initiate transactions from that address on your behalf. Managed wallets support the full Prudra wallet feature set: receiving payments, outbound transfers, cross-chain bridging, child address derivation, and bank withdrawals.

​
How key custody works

The key encryption key (KEK) lives in KMS hardware — Prudra never stores it. The encrypted private key ciphertext lives in Postgres. Neither alone is sufficient to sign transactions — you need the KEK to decrypt the ciphertext, and the KEK never leaves KMS. Zero plaintext persistence: The plaintext private key exists only transiently in memory during a signing operation. It is never logged, never stored, never transmitted.

​
The wallet hierarchy

Each organisation has one encrypted master seed. All wallet addresses — master and child — are deterministically derived from this seed using BIP-44 hierarchical deterministic derivation. Each address is unique and independent.

​
What you get when you provision

When you call provisionWallet(), Prudra:
  1. Generates a new EVM keypair in memory
  2. Encrypts the private key with the KEK via KMS
  3. Stores the ciphertext in the OrganisationWalletKey table
  4. Returns the wallet address immediately
The provisionStatus is "provisioning" briefly, then "active" once the key is ready. Payments can only be received when status is "active".
