io.finnet

io.finnet is a US-based blockchain infrastructure company that provides institutional-grade Multi-Party Computation (MPC) custody and digital asset management for banks, funds, exchanges, and other financial organizations. Its central proposition is that institutions can hold and transact digital assets at scale without ever transferring custody to a third-party provider — and without a complete private key ever being assembled in one place.

The Problem It Solves

Traditional institutional digital asset custody forces a difficult choice. Delegating to a third-party custodian introduces counterparty risk; conventional multisig schemes still require a private key to be reconstructed in memory at signing time. io.finnet's Trustless MPC (tMPC) architecture eliminates both failure modes by distributing cryptographic signing authority across multiple independent parties and devices so that no complete private key ever exists or needs to be assembled, even during transaction signing.

How tMPC Works

At the core of io.finnet is a threshold signature scheme built on Secure Multi-Party Computation (MPC) and Threshold Signature Schemes (TSS). Users generate cryptographic key material locally and distribute shares to approved signers — which can be individual users, departments, or automated server processes — each holding a portion of signing power. A transaction executes only when enough signers whose combined signing power meets a pre-defined threshold collaborate. Key shares remain on each signer's own device and are never sent to io.finnet's servers or revealed to other participants.

A distinctive feature is weighted signing: rather than requiring any fixed M-of-N quorum, io.finnet lets administrators assign variable amounts of signing power to different participants. This enables nuanced governance policies — such as requiring senior approvals for large transfers while allowing automated flows for routine transactions — without compromising the trustless model. A Virtual Signer component handles policy management server-side for automated workflows.

For disaster recovery, io.finnet publishes an open-source command-line tool (io-vault-disaster-recovery-cli, AGPL-3.0) on GitHub, letting vault owners reconstruct funds from backup shares independently of the platform. The underlying threshold signature library (threshlib, MIT) supporting ECDSA and EdDSA signing is also open source.

Products

io.finnet's platform is organized into four products:

io.vault is the flagship self-custody wallet for institutions, launched in May 2024. It provides role-based permissions, multi-approver workflows, compliance audit logs, and CSV export for regulatory reporting. io.vault was independently audited by Kudelski Security before launch. Early institutional adopters include Ibanera and Evo Exchange.

io.network is a tokenization and stablecoin issuance layer running on a private, permissioned blockchain. It targets financial institutions looking to issue or settle using tokenized assets without deploying their own chain infrastructure.

io.flow is a 24/7/365 payment rail supporting multi-currency transaction processing, instant settlement, and core banking integrations. Compliance monitoring, anti-fraud tooling, and transaction alerts are built into the rail.

Developer APIs expose custody infrastructure as Wallet-as-a-Service via REST and GraphQL endpoints. io.finnet reports an average integration time of under one week.

Solana and Institutional Staking

In August 2025, io.finnet integrated Everstake — a major proof-of-stake infrastructure operator managing over $13 billion in staked assets across 85+ networks, with a zero-slashing record and SOC 2 Type II certification — to bring institutional staking directly into io.vault. The integration initially covers Ethereum and Solana, with 15 or more additional proof-of-stake assets planned. Users can stake SOL from their existing vaults without transferring assets off the platform: tMPC-secured approvals apply to staking transactions on the same basis as any other transfer, and existing compliance policies carry through.

Customers and Documented Deployments

io.finnet's homepage reports over 300 market participants in its network. Documented institutional deployments include Garlic Capital (OTC trading operations), OpenOcean (exchange swaps and limit order execution), Yellow (crypto exchange platform), and Tunnl (decentralized exchange security). The company has also announced a treasury yield integration with Braid. io.finnet targets banks, neo banks, crypto exchanges, OTC desks, investment funds, and electronic money institutions.

Partners listed on the platform include AWS, Blockaid, QuickNode, and Kiln.

Security and Compliance

io.finnet holds SOC 2 Type II and ISO 27001:2022 certifications and maintains GDPR compliance. The io.vault product was audited by Kudelski Security at launch. io.finnet is a member of the MPC Alliance, the industry body that promotes interoperable MPC standards. Built-in compliance tooling covers real-time monitoring, configurable alert rules, actor blocking, and full audit trails.

Team and Company

io.finnet Group Inc. was founded in 2021 and is headquartered in Raleigh, North Carolina, with offices in the United Kingdom, Spain, the Cayman Islands, and Singapore. CEO Gregory Pepin, who holds an economics degree from HEC Lausanne, leads the company. In November 2024, io.finnet signed a letter of intent with Metavisio (THOMSON Computing) to establish a joint venture targeting Web3-ready computers with a North American listing.

Ecosystem Fit

Within the Solana ecosystem, io.finnet's primary integration is institutional staking of SOL through its Everstake partnership, enabling regulated organizations to participate in Solana network validation rewards while assets remain under their own MPC-secured custody. The Wallet-as-a-Service developer APIs also allow applications building on Solana to embed institutional-grade key management without building bespoke custody infrastructure.
