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.
