In today’s fast-evolving world of digital asset management, choosing a secure and efficient custody solution is critical for enterprises, financial institutions, and high-net-worth individuals.

Among the top contenders in this space are io.finnet and Fireblocks, two leading platforms offering self-custody solutions powered by Multi-Party Computation (MPC). 

In this article, we’ll highlight io.finnet’s unique strengths while providing an objective comparison with Fireblocks, based on publicly available information as of May 2025.

io.finnet vs Fireblocks: Key Differentiators

While io.finnet shines in trustless digital asset custody and cost efficiency, Fireblocks offers strengths in exchange connectivity and compliance:

  • Pricing: io.finnet’s transparent, no-AUC-fee model supports cost-conscious users, whereas Fireblocks’ volume-based pricing suits larger enterprises with tailored needs. (NB: AUC is short for Assets Under Custody.)
  • Custody Model: io.finnet’s tMPC (trustless Multi Party Computation) provides true self-custody with no single point of failure. It distributes key material directly  across multiple parties physical signing devices within an organization or across multiple organizations, reducing  counterparty risk or risk of internal fraud or collusion. Io.finnet never has access to any client key material. Meanwhile, Fireblocks’ MPC technology (Multi Party Computation) utilizes an API co-signer for secure signing. However, this is generally hosted by Fireblocks and dependent upon their infrastructure.
  • Exchange Connectivity: The Fireblocks platform leads with 28 exchange integrations, which is ideal for multi-exchange portfolios. io.finnet’s 14+ integrations offer robust portfolio tracking.
  • Security: io.finnet uses CGGMP21, a next-gen MPC protocol that avoids vulnerabilities in older implementations like GG18 and GG20. This ensures cutting-edge protection from cyber attacks and malicious activity. Meanwhile, Fireblocks uses its MPC-CMP protocol, which also offers strong protection against cyber threats.

Comparison Chart: io.finnet vs Fireblocks

Here’s a side-by-side look at how io.finnet and Fireblocks compare across core features like custody model, DeFi access, pricing model, security, and more:

Key Share Distribution Trustless MPC – no private key shares ever held or accessed by io.finnet. MPC with Fireblocks acting as co-signer. io.finnet ensures full user control; Fireblocks is typically still in the signing path.
MPC Implementation MPC is enforced directly on end-user devices, with thresholds and approvals hard-coded at the protocol level. MPC shares distributed between provider and/or client servers, with policies enforced via software. io.finnet enforces governance cryptographically, Fireblocks via policy software.
Vaults & Configuration Unlimited vaults, segregated addresses, variable thresholds, and weighted signing powers. Configurable instantly. Limited workspaces; changes may require provider intervention and added costs. io.finnet offers fast, self-service setup; Fireblocks often requires support involvement.
Pricing Model Affordable subscription, no AUC or volume-based fees, no lock-in. Premium pricing with AUC/volume fees and annual contracts. io.finnet offers affordable, transparent, predictable costs; Fireblocks pricing scales with volume.
Disaster Recovery Trustless, open-source disaster recovery. Users can recover funds offline using backup shares and 24-word secret phrases, with no third-party dependencies.
