Direct Custody WaaS

Fireblocks is a comprehensive digital asset custody and transfer platform designed for enterprises, financial institutions, and blockchain teams. It provides a secure environment to store, transfer, and issue digital assets, integrating multiple wallet types including vault accounts, internal and external wallets, contract wallets, exchange accounts, and fiat accounts. The platform supports automated transaction workflows, AML/KYT compliance, and real-time transaction monitoring through APIs and webhooks.

The platform's core offering is its secure vault infrastructure that leverages multi-party computation (MPC) technology to protect private keys and enable secure transaction signing. Fireblocks offers a REST API and SDKs in Python and JavaScript, allowing developers to automate asset management, create and manage wallets, execute transactions, and monitor asset balances programmatically. It supports advanced features such as idempotent transaction requests, IP whitelisting, and rate limiting to ensure secure and reliable API usage.

Fireblocks differentiates itself with its extensive support for various wallet types and asset classes, including UTXO and account-based blockchains, smart contract wallets, and fiat accounts. Its Gas Station service automates ETH fueling for ERC20 token transactions, reducing operational overhead. The platform also supports cross-border settlement flows, enabling predictable and transparent international payments. Fireblocks provides detailed transaction status tracking, approval workflows, and webhook event notifications for seamless integration into enterprise systems.

Developers can get started by generating API keys and CSR files for authentication, then use the Fireblocks SDKs or REST API to manage vault accounts, wallets, and transactions. Comprehensive documentation and code examples are available at the Fireblocks Developer Portal. The platform is actively maintained and widely adopted by financial institutions and blockchain enterprises seeking secure and scalable digital asset custody solutions.
