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.
