Research
The compliance architecture paper institutions are reading.
Blockchain Privacy Pools and AML Compliance covers how zero-knowledge privacy networks break traditional AML tooling, how Proof of Innocence and association sets restore compliance without exposing user data, and what the operational workflow looks like for stablecoin issuers and financial institutions navigating the privacy era.
Eleven chapters covering the technical foundation of privacy pools, why traditional AML breaks in shielded environments, association sets as a regulatory layer, Proof of Innocence and selective disclosure, audit keys for scoped and full disclosure on demand, the challenge-response operational workflow, a cross-border stablecoin payment use case, and the academic methodology behind the entity classification engine.

“Your creativity, collaboration, and innovation set a new benchmark for what's possible in capital markets technology.”
Johnna Powell, Research and Innovation MD, DTCC“The next era of institutional adoption belongs to protocols that can shield proprietary transaction data while simultaneously proving compliance to regulators.”
John Church, Duke & Nethermind“Handling compliance internally is an operational nightmare. AuditKey solves this by outsourcing the entire Proof of Innocence lifecycle. Their agents securely gather account and view keys, run live sanctions checks, and configure inclusion and exclusion association sets dynamically.”
Fatique, Founder, Ambar Capital“Even when you invest heavily in top-tier smart contract audits, static code reviews can only protect you so far. The real test happens when live funds are moving in the blockchain world. AuditKey's Mempool Defense provides that necessary, premier layer of live protection.”
Eduardo Maceira, CEO, Speck Finance“AuditKey replaces black-box data magic with a comprehensive VASP directory and deterministic labeling database. That clear line of tracking is what accelerates crypto investigations.”
Claudio Costa, Police Officer & Founder of Cilada Cripto“Scaling a stablecoin on Solana requires a compliance pipeline that matches the network's speed. AuditKey handles Solana screening natively, completely removing the manual bottleneck.”

Straight answers on how AuditKey works, what it screens, and how to start.
What is AuditKey?
AuditKey is a real-time blockchain compliance platform. It screens transactions in the mempool, before block finality, so stablecoin issuers, DeFi protocols, and digital asset institutions can block illicit transfers before they confirm, clear privacy-pool users without exposing their data, and draft localized SARs in minutes.
How is AuditKey different from Chainalysis, TRM Labs, and Elliptic?
While forensic tools only read public event logs after a transaction settles, AuditKey screens directly in the mempool to block threats before finality, verifies transactions on zero-knowledge networks where public logs don't exist, and leverages the most comprehensive VASP directory and labeling database optimized specifically for Brazil and Latam.
What does "compliance before finality" mean?
It means screening a transaction while it sits in the mempool, in the seconds before it is mined into a block. Counterparties are checked against sanctions lists and KYC registries in real time, so a flagged transfer can be blocked before it confirms instead of investigated after it settles.
Can AuditKey screen transactions on privacy networks like Railgun and Aztec?
Yes. On zero-knowledge networks, end users generate a Proof of Innocence using a view key or zero-knowledge proof, and AuditKey verifies that the funds are clean without exposing user data. This makes shielded transactions auditable while preserving privacy.
What is a Proof of Innocence?
A Proof of Innocence is a cryptographic or view-key-based attestation that funds in a privacy pool do not originate from sanctioned or illicit sources. It lets a legitimate user of a shielded network demonstrate compliance without revealing their full transaction history.
Does AuditKey support GENIUS Act and MiCA compliance?
AuditKey is designed for the controls these regimes require: real-time counterparty screening, KYC and sanctions checks, audit trails, and suspicious activity reporting. Confirm specific obligations with your compliance counsel for your jurisdiction.
Does AuditKey support the Travel Rule and VASP screening?
Yes. AuditKey includes VASP intelligence and Travel Rule status so institutions can screen counterparties and counterpart institutions across chains as part of their compliance workflow.
Can AuditKey automate Suspicious Activity Reports?
Yes. AuditKey's AI investigator analyzes an address with jurisdiction-aware context and drafts a localized SAR in minutes, replacing the manual stitching that typically takes analysts days.
Who is AuditKey for?
AuditKey serves stablecoin issuers focused on regulatory compliance, DeFi protocols focused on security, fintechs that need to screen at payment volume, and institutions and digital asset desks entering stablecoins and RWA.
Is there a free tier?
Yes. You can create a free account and screen an address with no credit card. Upgrade when you are ready for production volume.
Which blockchains does AuditKey support?
AuditKey supports Ethereum and EVM-compatible chains, Tron, Solana, and Bitcoin. Confirm the current supported network list in the product documentation.
