Where Crypto Platforms Struggle - and
How FinLego Helps

Fragmented Wallet Infrastructure

Managing wallets for fiat, crypto, and stablecoins across chains and custody providers is complex.

→
FinLego offers unified custodial and non-custodial wallets with multi-chain support and integrated fiat on/off-ramps.
Manual Trade Reconciliation

High-volume OTC desks and exchanges often suffer from reconciliation delays and errors.

→
FinLego’s double-entry ledger with timestamped records automates transaction tracking, FX logic, and settlements.
Fiat Integration Bottlenecks

Connecting banks, PSPs, and payout networks across regions is time-consuming.

→
FinLego connects you to global fiat rails (SEPA, SWIFT, FPS) and PSPs with a single integration and dynamic routing.
Compliance Gaps & Risk Exposure

Onboarding users in different jurisdictions without proper KYC/AML layers risks major compliance issues.

→
Use FinLego’s jurisdiction-aware onboarding, transaction monitoring, and sanctions screening - all out-of-the-box.
