What Is Wallet-as-a-Service (WaaS)?

What is Wallet-as-a-Service? In short, Wallet-as-a-Service (WaaS) is an API-based wallet infrastructure solution that enables businesses to integrate digital asset wallet functionality into their existing applications or platforms without building the underlying infrastructure from scratch.

Instead of developing private key management systems, blockchain integrations, and transaction signing mechanisms in-house, businesses can leverage a WaaS provider’s infrastructure to simplify wallet operations and accelerate deployment.

Key Features of Wallet-as-a-Service

The easiest way to understand what Wallet-as-a-Service is, is to look at what it does. Depending on the provider, WaaS typically supports the following capabilities:

• Wallet creation and multi-chain support: Create and manage wallets and addresses across supported blockchain networks.
• Digital asset deposits and withdrawals: Manage incoming and outgoing digital asset transactions.
• Private key management and transaction signing: Protect cryptographic keys and securely authorize blockchain transactions.
• Transaction monitoring: Track on-chain transactions and their status.
• Automated operations: Streamline transaction approvals, asset sweeping, and other wallet management workflows.
• Access controls: Configure permissions and transaction approval policies.

Wallet-as-a-Service vs. Traditional Digital Wallets

When learning what Wallet-as-a-Service is, many people confuse it with traditional digital wallets. Unlike traditional digital wallets that primarily focus on fiat payments, loyalty programs, and merchant transactions, crypto Wallet-as-a-Service focuses on blockchain infrastructure, digital asset security, and transaction management.

Self-Custody Architecture Powered by MPC and TEE

Safeheron combines Multi-Party Computation (MPC) and Trusted Execution Environment (TEE) technologies to provide multiple layers of protection for enterprise digital assets.

With MPC, private key control is distributed across multiple key shares, allowing transactions to be signed without reconstructing the complete private key during normal operations.

These capabilities allow developers to integrate wallet functionality into existing business systems without building complex wallet infrastructure from scratch.

To support large-scale digital asset operations, Safeheron also offers API Co-Signer capabilities, batch address generation, automated asset sweeping, and reconciliation-related features. These tools help businesses streamline transaction approvals and deposit and withdrawal workflows while reducing repetitive manual processes.
