What Primus Labs does
Primus Labs, founded in 2023 and headquartered in Hong Kong (formerly operating as PADO Labs), builds cryptographic verification infrastructure that bridges Web2 data and Web3 applications. The company's core technology stack combines zkTLS (zero-knowledge transport layer security) and zkFHE (zero-knowledge fully homomorphic encryption), enabling verifiable data flows, state attestations, and computation across blockchains, APIs, and real-world systems without exposing raw data. Its product surface includes the AlphaNet decentralized attestor network, the Primus browser extension (Chrome/Edge), the Developer Hub and SDKs (MPC-TLS SDK, Primus Skills), and purpose-built products such as Proof-of-Reserves for institutional reserve attestation, zkDID for privacy-preserving identity, and provable agentic execution for AI workflows.
The company targets a horizontal developer and protocol audience spanning Web3 builders, DeFi protocols, AI agent platforms, and financial institutions requiring verifiable off-chain data and confidential computation. Go-to-market is product-led and community-led, relying on self-serve onboarding through documentation, GitHub, Discord, and Telegram rather than a direct sales motion. The company has established itself as a core contributor to the BNB Attestation Service and counts 25+ integration partnerships across major blockchain ecosystems including Brevis, Nillion, Phala, Kite AI, Scroll, Linea, PolygonID, and Ethereum Foundation-supported grants.
Primus has raised approximately $9.5 million across disclosed rounds ($3M seed in August 2023 and $6.5M in February 2025) from investors including VanEck, Samsung NEXT, Alchemy, Dispersion Capital, Symbolic Capital, and Maelstrom, with additional research backing from the Ethereum Foundation and PSE. Pricing and revenue are not publicly disclosed, and the company operates with a small team of 11-50 employees. Its competitive position rests on proprietary cryptographic primitives, protocol-level integrations, and an emerging decentralized attestor network rather than scale advantages.

Primus Labs product offering
Product offeringCore offering
Primus Labs provides a unified verification layer powered by zkTLS (zero-knowledge transport layer security) and zkFHE (zero-knowledge fully homomorphic encryption) that enables verifiable data, state, and action verification across Web2 and Web3 ecosystems. The company offers a decentralized verification network (AlphaNet), cryptographic protocols, developer SDKs, and application-layer products such as Proof-of-Reserves and verifiable identity frameworks, primarily serving AI agents, DeFi protocols, and financial institutions.
Product overview
Primus Labs provides a unified verification layer that powers verifiable data, actions, and execution across AI agents, DeFi, and Web3 applications. The platform comprises a core decentralized network (AlphaNet), cryptographic protocols (zkTLS and zkFHE), developer tools (Developer Hub, Skills framework), browser extension, and specific products like Proof-of-Reserves and Data Verification. The architecture uses zkTLS for verifying off-chain data from Web2 into Web3 and zkFHE for encrypted computation, enabling trustless verification for AI agents, financial applications, identity systems, and decentralized finance without compromising data privacy.

Primus Labs competitors and assessment
Company assessmentDirect peers
- Nillion: Privacy-preserving blind computation network that consumes zkTLS-verified private data from Primus. Directly comparable as a complementary rather than competing layer, but also a potential competitor as Nillion builds its own data verification capabilities on top of its blind compute primitives.
- Phala Network: TEE-based confidential computing network into which Primus's attestor service is integrated. Directly comparable as both a partner and adjacent infrastructure for verifiable off-chain computation, with overlapping AI-agent and DeFi use cases.
- Brevis: zk coprocessor for verifiable off-chain data computation that co-builds products with Primus (e.g., PoR for USD*, privacy-preserving DeFi identity). Strong overlap in zk-based data attestation and on-chain proof generation targeting similar DeFi and RWA customers.
- Reclaim Protocol: zkTLS-based protocol for proving the authenticity of Web2 data onchain, addressing similar use cases (zkKYC, credentials, off-chain data attestations). Closest direct competitor on the zkTLS verification primitive itself.
Emerging players
- Axiom: zk coprocessor for Ethereum enabling smart contracts to compute over historical onchain data with ZK proofs. Adjacent in zk-based verifiable computation targeting DeFi and AI developers.
- RISC Zero: Provider of zkVMs for general-purpose verifiable compute. Comparable as zk infrastructure for AI and DeFi use cases, with stronger developer tooling and higher funding scale.
- Modulus Labs: zkML company bringing machine learning inference onchain with zero-knowledge proofs. Closely comparable in targeting the verifiable-AI narrative Primus pursues via Provable Agentic Execution.
- API3: First-party oracle network bridging Web2 APIs to Web3 with cryptographic guarantees. Comparable on the Web2-to-Web3 data attestation axis though using different mechanisms (Airnode + OEV) rather than zkTLS.
- Polyhedra Network: zk proof infrastructure provider with zkBridge, zkLightClient, and ProofCloud. Overlaps with Primus's zk-based interoperability and verification ambitions, with significantly larger funding and ecosystem reach.
Broad incumbents
- Chainlink: Dominant oracle and data verification network across crypto. While not zkTLS-native, Chainlink's expanding PoR and Cross-Chain Interoperability Protocol overlap with Primus's verification and reserve-attestation use cases at much greater scale.
