The Invisible Wallet
Monipay generates an Ethereum-compatible private key locally, encrypted with your PIN. Self-custody without seed phrases.
Key Generation
Monipay uses a Cryptographically Secure Pseudorandom Number Generator (CSPRNG) to generate a new private key directly on your device. This key is never transmitted to Monipay's servers in its unencrypted form.
Encryption Model
- Algorithm: AES-256-GCM
- Key Derivation: Argon2id PIN hashing
- Storage:
localStorage(web) + Secure Enclave / KeyStore (native)
Solana Ed25519 Model
For Solana, Monipay uses a twin-key Ed25519 model. The encrypted key is stored locally and never written to the database. Account deactivation is handled via a soft delete in the backend.
