WaaS sans garde

Fireblocks Non-Custodial Wallet-as-a-Service (WaaS) is an API-driven platform designed to enable organizations to securely store, transfer, and manage digital assets across a broad ecosystem including vault accounts, internal and external wallets, contract wallets, exchange accounts, and fiat accounts. It supports a wide range of asset types and provides granular control over wallet management, transaction workflows, and compliance integrations. The platform is intended for infrastructure teams, financial institutions, and enterprises requiring robust security and operational efficiency in digital asset custody and transfer.

The service offers a comprehensive REST API with SDKs in Python and JavaScript, enabling full automation of transaction flows, wallet lifecycle management, and real-time event notifications via webhooks. Key features include multi-layer wallet structures (vaults, internal/external wallets, contract wallets), transaction authorization policies, AML/KYT customer reference integration, and advanced transaction controls such as fee estimation, cancellation, freezing, and replacement of stuck transactions. Fireblocks also supports cross-border settlement flows and fiat account management, making it suitable for complex multi-asset and multi-jurisdictional operations.

What differentiates Fireblocks WaaS is its unified platform approach combining custody, transfer, compliance, and settlement capabilities with high security standards including MPC (Multi-Party Computation) signing and API co-signer support. The platform’s webhook system provides reliable event-driven updates with signature verification to ensure integrity. Fireblocks is widely adopted by institutional clients and enterprises, although specific user counts are not publicly disclosed. The platform’s extensive API coverage and operational tooling make it a preferred choice for teams building secure and compliant digital asset infrastructure.

Getting started involves generating API keys with RSA 4096-bit keys, setting up IP whitelisting, and integrating the REST API or SDKs. Developers can automate wallet creation, asset management, and transaction workflows while leveraging Fireblocks’ gas station for Ethereum address fueling. Comprehensive documentation and code examples are available at the Fireblocks Developer Portal to facilitate onboarding and integration.
