Our Mission

Trust Is Infrastructure. We Build It.

The financial system is being rewritten in code. Programmable money moves without intermediaries. Digital assets settle without custodians. Autonomous AI systems transact on behalf of their principals. And all of it depends on one thing - cryptographic trust.

VectorGuard Labs exists to build that trust layer: the software, protocols, and security infrastructure that lets these systems operate with verifiable correctness rather than institutional blind faith.

We are not a consultancy. We are an engineering lab. Every product we ship is a precision tool - open-source where possible, adversarially tested, and built to the standards that regulated financial systems demand.

Cryptographic Correctness

We use proven primitives - AES-256-GCM, Ed25519, BLAKE3, Argon2id - never custom cryptography. Every security decision is documented and auditable.

On-Chain Verifiability

Wherever possible, our systems anchor trust on-chain - so any party can independently verify claims without trusting VectorGuard Labs or any other intermediary.

Adversarial Rigor

We design systems assuming a motivated, well-resourced attacker. Threat models are explicit. Limitations are disclosed. Security theater has no place in infrastructure.

Radical Transparency

MIT-licensed source code. Honest documentation. Acknowledged limitations. We believe in infrastructure you can read, audit, and trust because you verified it yourself.

Our Vision

A World Where Value Flows Without Permission - But Not Without Proof.

Programmable Money

Smart contracts and autonomous systems handle transactions worth billions of dollars. We envision a financial layer where every key that authorizes a transaction is protected, every ledger entry is tamper-evident, and every signing operation is audited - without relying on a trusted third party to keep it honest.

Digital Assets

The ownership and transfer of digital assets demands the same assurance as physical property rights. We are building the cryptographic underpinning - verified credentials, on-chain attestation, and hardware-grade key management - that makes digital asset infrastructure worthy of institutional adoption.

Autonomous AI Systems

AI systems that act autonomously - managing wallets, issuing credentials, executing trades - require a trust layer that proves identity, enforces access policy, and creates an unforgeable record of every decision. That infrastructure does not yet fully exist. We are building it.

"The internet moved information without permission. The next layer moves value and authority without permission - but it will only succeed if the trust infrastructure underneath it is cryptographically sound."

Why It Matters

The Problem We're Solving

Keys Are the Attack Surface

Most applications embed encryption keys in environment variables, config files, or source code. One breach exposes everything. Private keys securing wallets and signing transactions deserve a proper vault - not a .env file.

Financial Records Can Be Silently Altered

Traditional databases have no tamper detection. A record written five years ago can be changed with no trace. Regulated financial systems, payment processors, and institutions need ledgers where historical manipulation is cryptographically detectable.

Identity Is Not Verifiable On-Chain

KYC and AML compliance generate credentials stored in siloed, opaque systems. On-chain protocols have no way to verify real-world identity claims without trusting a single intermediary. W3C Verifiable Credentials with on-chain attestation change that.

Smart Contracts Ship With Unvalidated Attack Surfaces

MEV searchers, flash loan attackers, oracle manipulators, and governance abusers exploit protocols that were never adversarially tested. Traditional audits often stop at pattern matching. Real security requires adversarial, exploit-backed validation.

Our Products

Four Tools. One Trust Stack.

Four products. Four layers. One complete trust stack - from cryptographic key management to on-chain credential verification.

Financial Infrastructure
⭐ Flagship · Written in Rust

VectorLedger

A cryptographically verifiable database engine for institutions that can't afford to trust their own database.

VectorLedger is a purpose-built, append-only financial ledger written entirely in Rust. Every journal entry is linked by a tamper-evident BLAKE3 hash chain, every page is encrypted at rest with AES-256-GCM, and every query result can carry a Merkle proof. Historical tampering is cryptographically detectable - always.

  • BLAKE3 hash chain - any modification invalidates every subsequent hash
  • Ed25519 commit signing on every WAL record
  • AES-256-GCM encryption at rest with per-table HKDF-derived keys
  • Four-eyes dual-control approval workflow
  • WORM audit log with its own independent BLAKE3 chain
  • PostgreSQL wire protocol - drop-in compatible with psql, pgAdmin, DBeaver
  • SOC 2 Type II & PCI-DSS v4 compliance-ready audit trails
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/pavondunbar/VectorLedger/main/install.sh | bash

A record written five years ago cannot be changed without invalidating every hash in the chain from that point to the present.

Key Management
Open Source · MIT

PyHSM

Software Key Management Service - a bank vault for your application's secrets.

PyHSM is a software KMS built for teams that need serious key management without hardware dependencies. It securely stores encryption keys, signs data, manages key lifecycles, and maintains a tamper-evident HMAC-chained audit log of every operation. No hardware required. No cloud dependency. No vendor lock-in.

  • AES-256-GCM double-encrypted keystore with Argon2id key derivation
  • Shamir Secret Sharing for M-of-N master key custody
  • HMAC-chained tamper-evident audit log
  • secp256k1 & Ed25519 signing for Ethereum, Bitcoin, Solana
  • Process isolation - key material in a separate OS process
  • Python & TypeScript - full feature parity across both stacks
pip install vectorguard-pyhsm

Think of PyHSM as the locksmith - managing your keys, tracking access, and ensuring nothing is left exposed.

Identity & Compliance
W3C Compliant · On-Chain

Verified Credentials

W3C-compliant credential issuance with on-chain attestation anchoring on Base.

Vercre is an open-source W3C Verifiable Credentials SDK that issues KYC, AML, and accredited investor credentials as signed JWTs and anchors their hashes on-chain for tamper-proof, publicly verifiable proof. Privacy by design - only cryptographic hashes are stored on-chain, never personal data.

  • W3C Verifiable Credentials Data Model v2.0 compliance
  • Ed25519 & secp256k1 JWT signatures
  • On-chain attestation anchoring on Base (EVM)
  • KYC, AML & AccreditedInvestor credential schemas
  • Trust registry with four issuer tiers and reputation scoring
  • SD-JWT selective disclosure - share only what's needed
  • 70+ REST API endpoints with three-tier role-based auth
pip install vercre-sdk

Any platform can verify attestation status on-chain without re-running compliance checks - no intermediary required.

Preliminary Audit

Adversarial pre-audit security assessments - prepare for Tier-1 audit firms with exploit-backed coverage.

VectorGuard Labs delivers adversarial pre-audit assessments using its 15-Phase Framework and 338-vector attack library. We threat model, fuzz, simulate, and - where possible - build working exploit PoCs on forked mainnets. Every Critical, High, and Medium finding is proven with a TX hash, not speculated. We prepare you for Trail of Bits, OpenZeppelin, Certik, and Cyfrin - we don't replace them.

  • 338-vector attack library built from real-world exploits - MEV, flash loans, oracle manipulation, governance capture
  • Fork-based exploit validation with TX hashes, state diffs & attacker balance deltas
  • Invariant-driven analysis - solvency, access control, economic safety
  • Solidity, Vyper, Rust, Cairo & Move contract support
  • One complimentary retest included with every engagement
  • Validated-only reporting - no fabricated findings, no severity inflation

If a protocol is sound, we explicitly state: "No Actionable Risks. Ready for Formal Audit." Truth - not theatrics.

The Trust Stack

How the Products Fit Together

Each VectorGuard Labs product occupies a distinct layer. They are independently useful and composable as a full-stack trust infrastructure.

VectorLedger is the flagship layer - tamper-evident records anchored by PyHSM keys, verified by Verified Credentials, and secured before deployment by the Preliminary Audit.

Why VectorGuard Labs

Built for Institutions That Can't Afford to Be Wrong.

For enterprise teams and investors evaluating trust infrastructure, the question isn't whether cryptography matters - it's whether the team building it has the rigor, transparency, and depth to be trusted with critical systems.

Engineering-First, Not Consulting-First

Every product ships as auditable, open-source code - not advisory reports. We are accountable to the same standards we preach: proven primitives, documented threat models, and disclosed limitations.

Open Source Where It Counts

PyHSM and Vercre SDK are MIT licensed. You own the code. You can audit every cryptographic decision. No black boxes, no trust-me security, no vendor capture on your most critical layer.

Verifiable, Not Claimable

On-chain attestation, BLAKE3 hash chains, and tamper-evident audit logs mean correctness is provable - not asserted. Any auditor, regulator, or counterparty can independently verify without asking us first.

Designed for the AI-Agent Economy

Autonomous systems need cryptographic identity, verifiable authorization, and unforgeable audit trails. We are building that infrastructure now - not retrofitting web2 security patterns onto autonomous systems.

Regulation-Ready by Design

VectorLedger's compliance-ready audit trails, Verified Credentials' W3C-standard KYC/AML schemas, and our adversarial audit methodology are built for the scrutiny of financial regulators - not designed around it afterward.

Honest About What We Are

We are a pre-audit firm, not a replacement for Trail of Bits. PyHSM is a software KMS, not a hardware HSM. We tell you what the products do, what they don't, and where the trust boundaries lie.

"Trust but verify."
