About

What is Blockdaemon?

Blockdaemon sells blockchain infrastructure to financial institutions: staking and staking APIs, a self-hosted MPC institutional vault, RPC and data services. Its staking page says it has helped companies deploy $6+ billion worth of staking infrastructure, and its homepage cites ISO 27001 certification.

How Blockdaemon works

Blockdaemon runs nodes and validators as a managed service and sells API access on top of them.

The Staking API turns a standard input into protocol-specific staking transactions for Ethereum, Solana, Polkadot, Polygon, NEAR, Cardano, Cosmos, BNB and Avalanche; you sign and broadcast them from your own wallet, and for Ethereum it provisions validators on demand. The RPC and REST APIs meter every call in compute units, from 1 unit for the lightest methods to 100 for the heaviest.

Institutional Vault is self-hosted MPC wallet software. You run key shares and policies in your own environment or in secure compute such as AWS Nitro or Azure, with optional air-gapped signing, biometric approvals and hot, warm and cold accounts. It handles ERC-20, ERC-1404 and ERC-3643 tokens and staking from the wallet. On the validator side, engineers perform failovers manually from written runbooks to avoid the double-signing risk of automated failover, and nodes sit in Tier 3 data centers with DDoS protection.

How to start with Blockdaemon

You create a free account at app.blockdaemon.com with Google, GitHub or email, and two-factor authentication with an authenticator app is required.
You then set up a workspace, choose what you plan to use, and can send your first API request.
Some products need Know Your Business verification: a customer success manager must enable it for your workspace, only admins can complete it, and it includes consent to biometric checks.
Write calls to sanctioned addresses are blocked automatically under OFAC screening.

Blockdaemon fees and limits

The API plans are Free, Starter, Growth and Enterprise, and every call is weighed in compute units. The rate limit is 5 requests per second on Free, 100 on Starter and 200 on Growth, with custom limits on Enterprise, and the Staking API is capped at 250 requests per minute unless support raises it. Dedicated nodes are not rate-limited. Dollar prices for the plans, staking commissions and Institutional Vault licenses are not listed on the pages we checked, so you get them from sales.

Risks to know before using Blockdaemon

Blockdaemon describes its products as non-custodial, so key custody and recovery stay with you; Institutional Vault uses self-managed key recovery with no vendor dependency.
The company cites SOC 2 Type II, achieved in June 2025, ISO 27001 from July 2022, and 100% slashing-risk coverage built with the insurance broker Marsh.
The page does not publish coverage limits or exclusions, so ask for the policy terms before you rely on it for a large stake.
