Choose a wallet type

Prudra supports two wallet types: managed and BYO. The right choice depends on whether you need Prudra to initiate transactions on your behalf, and whether you already have an existing wallet address.

​
Decision table

​
BYO wallet

You own and control the private key. Prudra monitors your address using blockchain address monitoring — it fires deposit.success webhooks when funds arrive and maintains a balance view, but it never initiates transactions. Pros:
  • No custody relationship with Prudra
  • Works with any existing EVM wallet
  • Fast setup (register an address, done)
  • No key management to think about
Cons:
  • No outbound transfers from Prudra
  • No bank withdrawals via Prudra
  • No child address generation
  • Manual fund management required
Plan limits:
  • Hobby: 1 BYO wallet
  • Pro: 5 BYO wallets
  • Enterprise: unlimited BYO wallets

​
Managed wallet

Prudra generates a private key and custodies it using KMS envelope encryption. The key never exists in plaintext outside hardware. You get an address; Prudra can initiate transactions from that address on your behalf. Pros:
  • Outbound transfers, swaps, and bridges
  • Bank withdrawals (crypto → fiat → wire)
  • Child addresses for per-customer isolation
  • No key infrastructure to manage
Cons:
  • Prudra holds custody of the key
  • One master wallet per plan (Hobby/Pro)
  • Requires trust in Prudra’s key management
Plan limits:
  • Hobby: 1 managed wallet, 1 active chain
  • Pro: 1 managed wallet, 5 active chains
  • Enterprise: unlimited managed wallets and chains

​
Child addresses

Child addresses are unique EVM addresses derived from a managed master wallet using BIP-44 hierarchical deterministic derivation. Each child address is independent and receives funds separately. Use cases for child addresses:
  • Issue a unique deposit address to each customer
  • Separate payment flows by product line or geography
  • Limit blast radius if one address is compromised
Child addresses are unlimited on all plans. They require a managed wallet.

​
When to use both

Some organisations use both: a BYO wallet for payment receipt on existing infrastructure, and a managed wallet for treasury operations (outbound transfers, withdrawals). The walletMiddleware can be configured per-route to use different wallets.
