Adding Crypto Wallets to Your Platform — Bridging Fiat and On-Chain

How to offer multi-chain crypto wallets alongside virtual accounts and cards, giving your customers a single platform for fiat and digital assets.

8/5/2025

Your customers increasingly want to hold and transact in both fiat and crypto. Offering both from a single platform removes friction and unlocks new use cases.

Why offer crypto wallets

  • Customers can hold stablecoins alongside their fiat balance
  • Cross-border payments become faster and cheaper
  • New revenue opportunities from on-chain transactions
  • Attract crypto-native businesses to your platform

Multi-chain support

Ledger supports wallets across major blockchains — Ethereum, Bitcoin, and Solana. Each wallet is tied to a verified customer and managed through the same API you use for virtual accounts and cards.

The unified account model

A single customer can have:

  • One or more virtual accounts (USD, EUR, etc.)
  • Virtual and physical cards linked to those accounts
  • Crypto wallets across multiple chains

Funds can move between accounts and wallets through internal transfers. Your customers see one balance sheet, not three separate products.

Key capabilities

  • Programmatic wallet creation: create wallets via API, one per customer or per use case
  • Deposit and withdrawal: fund wallets from virtual accounts or external sources
  • Transaction tracking: every on-chain transaction is logged and visible in the dashboard
  • Spend controls: apply the same limits and policies you use for cards

Getting started

If your platform already uses Ledger for accounts or cards, adding wallets is a single API call. New customers go through the same KYB flow and get access to all three products.

Crypto wallets don't have to be a separate product. Get started with Ledger's unified financial platform.
