0xbow

What 0xbow does

0xbow is a blockchain privacy infrastructure company that builds zero-knowledge proof (zk-SNARK) based tools enabling private on-chain transactions while excluding funds linked to illicit actors. Founded in 2023, headquartered in Nashville, TN (incorporated in Delaware as 0xbow Limited), the company operates with an 11-50 person team and is incubated by NumberGroup. Its core product, Privacy Pools, is a mixing protocol deployed on Gnosis and Ethereum Mainnet that lets users generate membership proofs demonstrating their funds originated from legitimate sources without revealing identity or transaction details. Compliance is enforced through the Association Set Provider (ASP), which performs continuous Know Your Transaction (KYT) monitoring and maintains an on-chain registry of vetted addresses, and through a Proof of Association API that publishes a whitelist status valid for 6 months. The company also operates the Tornado Cash Proof of Association service, a privacy-preserving bridge for Tornado Cash users to demonstrate non-association with illicit activity.

0xbow's business model is primarily transaction-based: the company charges a 0.25% fee on each cryptocurrency deposit into Privacy Pools, debited directly at deposit time and disclosed in its Terms of Service. A secondary, subscription-style revenue stream is the Proof of Association API, which lets third parties query wallet risk and sanctions status. Distribution is product-led and self-serve through the privacypools.com dApp and tornado.0xbow.io interface, supplemented by open-source GitHub repositories, a Telegram community, technical blog content, and event-driven activations such as the Trusted Setup Ceremony at ETHDenver (over 500 contributors). Customer segments include privacy-conscious DeFi users (primary), enterprises and institutions requiring customizable compliance, L1/L2 blockchain ecosystems invited to enable Privacy Pools on their networks, and other privacy protocols that can integrate the ASP.

Recent strategic activity indicates an expansion phase: in 2025 the company completed the Trusted Setup Ceremony, launched Privacy Pools and ASP, closed a $3.5M funding round in November 2025 led by Starbloom Capital with Coinbase Ventures, Boost VC, Plutos Capital, and Status.im participating, and in January 2026 announced a co-development partnership with Brevis and BNB Chain to build an Intelligent Privacy Pool product. The company also lists support for Sky's USDS stablecoin as part of its distribution. Advisor roster includes Taylor Monahan, Nic Bax, and Oleksandr Brezhniev.

Revenue model

1. Transaction Fee (0.25%): The service charges 0.25% of each cryptocurrency deposit a user proposes to submit to a Privacy Pool. Fees are debited directly from the cryptocurrency being deposited at the time of deposit into the Pool. All fees are non-refundable.
2. Proof of Association Service: API service for third parties to check whether a particular wallet address is or is not identified as associated with high-risk activity or on a sanctions list. Proof of Association is published ('Whitelisted') for Ethereum privacy pools and maintained for 6 months before requiring re-verification.

Core offering

0xbow builds and operates privacy-preserving compliance infrastructure for public blockchains. Its core product, Privacy Pools, lets users deposit and withdraw cryptocurrencies anonymously via zero-knowledge proofs while proving funds are not co-mingled with illicit actors. The Association Set Provider (ASP) continuously monitors deposits, performs KYT analysis, and maintains an on-chain registry of vetted addresses, enabling developers and institutions to enforce rule-based compliance without compromising user privacy.

Product overview

0xbow is a privacy and compliance infrastructure company for DeFi, operating as a unified platform with multiple interconnected products. The core offering is Privacy Pools, a privacy-preserving mixing protocol that allows users to transact privately while proving fund legitimacy through zero-knowledge proofs. This is supported by the Association Set Provider (ASP), which monitors transactions, performs KYT analysis, and maintains a vetted address registry. The Proof of Association API provides third-party access to wallet compliance status. The Tornado Cash Proof of Association bridges Tornado Cash users to the compliance ecosystem. All products leverage zero-knowledge cryptography to enable compliant on-chain interactions where users can prove eligibility without revealing identity or transaction details.

Functional benefit

Products and services

• Privacy Pools A privacy-preserving mixing protocol that lets users conduct arbitrary peer-to-peer private blockchain transactions without the risk of funds being mixed with those of illicit actors. Users deposit into and withdraw from pools on Gnosis and Ethereum Mainnet, using zero-knowledge proofs to demonstrate membership in a compliant set without revealing identity or transaction details.
• Association Set Provider (ASP) A compliance tool that continuously monitors deposits into Privacy Pools, performs Know Your Transaction (KYT) analysis to detect suspicious patterns, and maintains an on-chain Association Set of vetted addresses. Developers and institutions can query the ASP to enforce rule-based access control without compromising user privacy, with programmable compliance levels for different jurisdictions.
• Proof of Association API An API service that lets third parties check whether a given wallet address is or is not identified as high-risk or on a sanctions list, returning a 'Whitelisted' Proof of Association status for Ethereum privacy pools that is valid for 6 months before re-verification.
• Tornado Cash Proof of Association (PoA) A privacy-preserving bridge between Tornado Cash and compliance that lets users prove their withdrawal addresses are not linked to illicit activity without revealing their identity or the underlying note.
• Privacy Pools Smart Contracts The on-chain smart contract layer of Privacy Pools deployed on supported networks, providing the entrypoint and pool logic that users interact with to deposit and withdraw using zero-knowledge proofs.

Broad incumbents

• TRM Labs: TRM Labs is a blockchain intelligence and compliance platform that performs on-chain transaction monitoring, wallet risk scoring, and AML analytics. It represents the incumbent compliance side of the market that 0xbow's ASP competes with/integrates against for institutional customers.
• Tornado Cash: Tornado Cash is the original Ethereum zero-knowledge mixer that 0xbow's Proof of Association product directly bridges to. Although OFAC-sanctioned, it remains the protocol-of-record for private ETH transactions and defines the category in which 0xbow competes.
• Zcash: Zcash is the original privacy-focused blockchain using zk-SNARKs to shield transaction details. It is a broad incumbent in the on-chain privacy category and competes for the same philosophical and developer mindshare as 0xbow's privacy infrastructure.
• Chainalysis: Chainalysis is the leading blockchain analytics and compliance vendor, providing transaction monitoring, KYT, and investigation tools to governments, exchanges, and financial institutions. It is a broad incumbent in on-chain compliance that defines the requirements 0xbow's ASP must meet for institutional adoption.

Direct peers

• Railgun: Railgun is a privacy protocol on Ethereum that uses zero-knowledge proofs to enable private DeFi transactions while providing a compliance layer for excluding illicit funds. It is the closest direct competitor to 0xbow's Privacy Pools, addressing the same privacy-plus-compliance niche with overlapping zk architecture.
• Aztec Network: Aztec is a privacy-focused zk-rollup on Ethereum that enables private smart contract execution and transactions via Noir and PLONK-based proofs. While more general-purpose than 0xbow, it competes for the same privacy-preserving DeFi developer mindshare and end-user transaction flow.
• Panther Protocol: Panther Protocol is a privacy-preserving DeFi protocol that uses zk-SNARKs to enable compliant private transactions across multiple chains, similar to 0xbow's approach. It targets the same institutional and DeFi-native users seeking privacy with regulatory compatibility.

Emerging players

• Aleo: Aleo is a privacy-by-default L1 blockchain that uses zero-knowledge proofs to enable private smart contracts and transactions. It competes for the same developer and institutional market as 0xbow but takes a layer-1 approach rather than 0xbow's L2/middleware model.
• Polygon Miden: Polygon Miden is a zk-rollup that uses STARK-based proofs to enable private, asset-like accounts and local transaction execution. It is an emerging player in the privacy L2 space, competing with 0xbow for L1/L2 partners seeking to add privacy to their ecosystems.
• Secret Network: Secret Network is a privacy-preserving smart contract platform using trusted execution environments (TEEs) and encrypted computations. It overlaps with 0xbow in serving users who want private on-chain activity, though its approach is architectural rather than zk-based.
