Why Crypto Wallet Infrastructure Matters
Managing digital assets is risky without reliable wallet infrastructure. From key loss to regulatory exposure, building it from scratch is costly and complex.

FinLego Crypto Wallets provide both custodial and non-custodial wallet configurations within one modular platform. Our infrastructure supports institutional-grade custody, multi-signature key control, and seamless network connectivity.
Tailored Capabilities for Custody and Self-Custody
Custodial Wallets
  • Enterprise-managed custody with secure private key storage using MPC across distributed enclaves.
  • Full user balance control, transaction monitoring, and compliance tools integrated.
  • Prominent uptime (99.95%) and secuee infrastructure.
Non-Custodial Wallets
  • Users retain private keys, reinforced by secure passkeys or hardware-backed authentication (biometric, WebAuthn).
  • Transaction governance through programmable workflows (Wallet Entitlement Management) ensures auditability and policy compliance.
Multichain & Asset Support
  • Secure connectivity across Bitcoin, Ethereum, stablecoins, and custom tokens.
  • APIs that support network switching, fee estimation, signature collection, and metadata tracking.
Governance & Workflow Controls
  • Configurable transaction policies include approval thresholds, signer quorums, and replay protection.
  • Built-in entitlement logic automates user roles and transaction permissions.
Ledger Integration & Crypto Transactions
  • Every on-chain event automatically updates your ledger and balances via FinLego’s financial engine.
  • Track asset flows alongside fiat, cards, and fees within unified accounting.
Secure API Suite & Dashboard
  • Use REST APIs to create wallets, initiate transactions, query history, or automate vault operations.
  • Back-office dashboards allow compliance teams to manage risk, review transactions, and audit wallet activity.
