What Fairblock does
Fairblock is a Toronto-based privacy infrastructure company founded in 2023 that builds multimodal cryptographic tooling for enterprises, focused on two product lines: confidential stablecoins and real-world assets for financial institutions, and private AI inference for enterprises that cannot share confidential data with cloud models. The underlying platform combines zero-knowledge proofs (ZKP), fully homomorphic encryption (FHE), multi-party computation (MPC), and trusted execution environments (TEE) under a dynamic, multimodal cryptography layer that selects the optimal scheme per use case, with claimed sub-second throughput and cross-chain support for Ethereum, Solana, Bitcoin, and Arbitrum. Distribution is via an SDK and API that integrate into neobanks, wallets, payment processors, custodians, and agentic platforms without changes to existing user flows.

Fairblock product offering
Product offeringCore offering
Fairblock builds a multimodal cryptographic privacy infrastructure delivered via SDK and API that enables enterprises to issue confidential stablecoins and real-world assets (RWA) and to run private AI inference. The platform combines ZKP, FHE, MPC, and TEE technologies to encrypt onchain transactions end-to-end while preserving compliance through selective disclosure, and integrates in 30 minutes into neobanks, wallets, payment processors, custodians, and agentic platforms across Ethereum, Solana, Bitcoin, and Arbitrum.
Product overview
Fairblock is an enterprise privacy infrastructure platform that enables confidential stablecoins and private AI through advanced cryptography. The core platform consists of an SDK and API that developers integrate into frontends, neobanks, wallets, or agentic platforms. The platform supports cross-chain deployment across Ethereum, Solana, Bitcoin, and Arbitrum, with native integration capabilities for neobanks, payment processors, and custodians. The infrastructure is built on multimodal and dynamic cryptography combining zero-knowledge proofs, trusted execution environments, and multi-party computation. A showcase of confidential applications demonstrates the platform's capabilities, including protected lending (Fairrates), protected predictions (Time Machine), protected AI agents (Unruggable AI), encrypted orders (FairyCoW), and confidential expense splitting (FairSplit).

Products and services
- Private Stablecoin Payments End-to-end encrypted stablecoin payments for institutions and individuals that hides transaction amounts, counterparties, and payment histories on public chains while preserving onchain verifiability and remaining fully compliant with AML and KYC requirements.
- Confidential AI Enterprise AI inference that runs persistently and accessibly without exposing confidential business or customer data to cloud models, using TEEs, MPC, and private decryption to satisfy enterprise compliance and profitability requirements.
- Fairblock SDK & API Developer toolkit that allows engineers to integrate Fairblock's privacy infrastructure into any frontend, neobank, wallet, or agentic platform, issuing cross-chain confidential stablecoins and RWA or connecting AI models with full privacy guarantees.
- Stabletrust: Confidential Stablecoins Confidential stablecoin application built with Fairblock's cryptographic stack, delivering fast, compliant, and cross-chain stablecoin transactions for institutional adoption.
- Fairrates: Protected Lending Fixed-rate lending protocol that uses leaderless sealed-bid auctions to deliver tighter margins, no slippage, and reduced liquidation penalties, live on Arbitrum One.
- FairyCoW: Protected Intents Trading protection application built with CoW Swap that protects sensitive order data before execution to prevent market impact and frontrunning without centralized parties.
- Time Machine: Protected Predictions Encrypted prediction market application that protects alpha and rewards early and accurate predictions with asymmetric payoffs, avoiding greeks, frontrunning, and oracle manipulation.
- Unruggable AI: Protected Agents Open-source solution for AI agents that combines TEEs, Fairblock's MPC, and private decryption to securely back up and recover keys without centralization when TEEs fail or restart.
- FairSplit: Confidential Expense Splitting Application for splitting stable tokens such as USDC with confidential transfers that tracks participant payments and settles balances onchain while revealing only the necessary information.
- Private Governance: Protected Votes Private onchain governance module that allows EVM and Cosmos users to encrypt their votes in any onchain poll to produce credibly neutral results.
- Verifiable Randomness Verifiable randomness service that supports a new generation of gaming, DeFi, distribution, and auction-based applications across multiple chains.
- Onchain Time Bomb (FairyRing Testnet) Public testnet experience for Fairblock's FairyRing network, including an interactive onchain encryption demonstration game that has logged over 50,000 testnet interactions since launch.

Fairblock competitors and assessment
Company assessmentDirect peers
- Secret Network: Secret Network provides programmable privacy for smart contracts using TEE-based confidential computing. It is a direct peer to Fairblock's multimodal cryptography approach; Fairblock already has a strategic partnership with Secret Network, indicating overlap in the privacy-preserving compute market for decentralized apps.
- Inco Network: Inco is a confidential computing network using FHE to enable private smart contracts across EVM chains. It is a direct competitor in the cross-chain confidential finance space, focusing on FHE where Fairblock offers a broader multimodal stack.
- Aleo: Aleo is a privacy-first L1 using zero-knowledge proofs to enable private applications. It targets similar enterprise and developer use cases as Fairblock (private finance, compliant confidentiality) but is built on a single ZK primitive, where Fairblock offers dynamic ZKP/FHE/MPC/TEE selection.
- Manta Network: Manta Network is a ZK-based privacy L2 providing confidential transfers and programmable on-chain privacy. It competes with Fairblock's stablecoin/RWA confidentiality but relies solely on ZK proofs versus Fairblock's multimodal cryptography.
- Zama: Zama builds open-source FHE libraries (Concrete, fhEVM) for encrypted computation on blockchain and AI. It targets the same developer audience as Fairblock with overlapping use cases in private onchain finance and confidential AI, though Zama focuses on FHE alone.
- Aztec Network: Aztec is a privacy-focused ZK rollup on Ethereum enabling encrypted transactions and private smart contracts via Noir. It competes with Fairblock in confidential onchain finance but uses a single cryptographic primitive (ZK), making Fairblock's multimodal approach its key differentiator.
- Oasis Network: Oasis Network offers confidential compute via TEEs and has a privacy-focused Sapphire EVM parachain. It overlaps with Fairblock on confidential smart contracts and private AI/data processing, with similar enterprise-friendly positioning.
Emerging players
- Penumbra: Penumbra is a privacy-preserving DEX and shielded asset protocol on Cosmos using ZK proofs. It overlaps with Fairblock on confidential trading and shielded asset transfers, serving a more narrow DeFi focus rather than enterprise privacy infrastructure.
- Arcium: Arcium (formerly Elusiv) is a parallelized confidential computing network using MPC and FHE for encrypted on-chain computation. It directly competes with Fairblock in the confidential compute / private smart contracts category on Solana and beyond.
- Railgun: Railgun is a privacy protocol using ZK proofs to enable private DeFi transactions on Ethereum. It overlaps with Fairblock's confidential finance use cases but is narrower in scope, focused on DeFi rather than a full enterprise privacy stack.
