Infrastructure

For Brokerage, Custody and Fiat Integration

NEXUS enables financial institutions, fintechs, and corporates to offer digital asset services without building and operating blockchain infrastructure. Abstracts wallet, transaction, and accounting complexity through operator portal and APIs.

Two Pillars of Digital Asset Services

Crypto Brokerage

Facilitate buying and selling of crypto-assets for customers. Receive and transmit orders, execute orders, provide quotes, and arrange settlement and delivery.

  • Order flow: receiving, routing, and executing customer orders
  • Pricing and execution with quotes, spreads, and fees
  • Settlement and on-chain delivery
  • Risk management: limits and exposure monitoring
  • KYC/AML, sanctions screening, transaction monitoring

Crypto Custody

Safekeeping and secure management of crypto-assets or private keys on behalf of customers, with operational administration around balances and transfers.

  • Secure key management with policies and multi-approval
  • Hot/cold wallet operating model
  • Deposits, withdrawals, and whitelisting
  • Off-chain balance administration and reconciliation
  • Segregation of duties and access control
