Security & Audit Solutions

HashLedger is a Toronto-based CPA firm founded in 2023 that prepares financial statements under GAAP or IFRS, maintains smart contract audit trails, and produces audit-ready documentation for crypto-native businesses. Tax engagements cover Canadian personal and corporate returns, US contractor payment reporting, and strategic planning including business structuring, international tax, and transfer pricing. For blockchain foundations and DAOs, the firm handles tax-exempt status applications and governance structure setup aligned with charitable regulations. The firm draws transaction data from blockchain nodes and verified APIs to produce records suitable for regulators and auditors. Token-specific compliance work covers issuance accounting, SAFT and SAFE instrument treatment, and vesting schedule management to reduce regulatory exposure. Clients include Verda Ventures and Swing.xyz, demonstrating experience across both venture fund and DeFi protocol compliance contexts.

Compliance is a structural feature of Bitbond's tokenization platform rather than an add-on, reflecting the company's positioning for institutional and regulated issuers in European markets. The platform's advisory layer specifically covers regulatory structuring under Germany's Electronic Securities Act (eWpG) and the EU's Markets in Crypto-Assets Regulation (MiCA). Bitbond received authorization from Germany's Federal Financial Supervisory Authority (BaFin) and describes its information security management as ISO 27001-aligned. Smart contracts on EVM-compatible chains have been audited by CertiK and AuditOne. Token-level compliance controls built into the platform include KYC-gating to enforce investor whitelists, transfer restrictions, freeze authority to pause individual holder accounts, and clawback capability for regulatory recovery of funds. The Offering Manager module handles standard KYC/AML investor onboarding as part of the primary issuance workflow. On Solana, Token-2022 transfer hooks allow compliance rules to be checked on-chain before each transfer, and the platform supports atomic Delivery versus Payment settlement to eliminate counterparty risk in primary transactions.

CODESPECT is a boutique blockchain security firm founded in May 2024 and headquartered in Opava, Czech Republic. Operating under the tagline "Every Attack Surface. One Team," it delivers end-to-end security coverage for Web3 protocols, spanning smart contract audits, penetration testing, AI agent security, red team exercises, on-chain monitoring, and operations security. Its researchers bring experience from competitive audit platforms including Cantina and CodeHawks, and the firm reports protecting over four billion dollars in total value locked across its client base. What distinguishes CODESPECT in the Web3 security landscape is its consolidation of multiple disciplines under a single team rather than requiring protocols to coordinate across specialized vendors. The firm notes that approximately 80 percent of exploited vulnerabilities in Web3 are business-logic flaws that automated scanners cannot detect, which motivates its emphasis on deep manual review. Coverage extends from on-chain smart contract code through web infrastructure, CI/CD pipelines, AI-integrated components, and governance key management, giving protocols a single point of accountability across their full technical and operational surface.

Automata Network provides cryptographic verification infrastructure using Trusted Execution Environments — Intel SGX/TDX, AMD SEV-SNP, and AWS Nitro Enclaves — to generate hardware-backed attestation reports for Web3 applications. These reports prove that computations ran inside genuine, isolated silicon and are verified directly by on-chain smart contracts, replacing trust in operators with verifiable cryptographic guarantees. The DCAP framework manages Intel certificate chain validation fully on-chain, eliminating centralized attestation services as a dependency. Production deployments with Uniswap, Flashbots, Scroll, and Linea demonstrate the maturity of Automata attestation. A Trail of Bits security review covering eight engineering weeks found the DCAP Attestation v1.0.0 repository well-structured with clear APIs. The SGX Prover and Verifier are open-source under the Apache 2.0 license, and DCAP support expanded to ten networks including Ethereum, Optimism, Base, and Worldchain in November 2025.

BitOK provides cryptocurrency compliance infrastructure that addresses the AML and sanctions screening obligations faced by exchanges, payment processors, custodial wallet operators, and stablecoin issuers. The KYT Office product delivers real-time transaction monitoring via API, configurable risk alerts, and sanctions checks aligned with regulatory frameworks governing crypto asset service providers across multiple jurisdictions. The platform also offers an AML Certification program that trains and credentials compliance officers in crypto-asset forensics methodology. A forthcoming Travel Rule module will extend coverage to the inter-VASP data-sharing obligations now mandated in several jurisdictions, positioning BitOK as a broader compliance stack for regulated crypto businesses.

HAPI Protocol embeds threat intelligence directly at the smart contract layer, enabling DeFi protocols to screen user wallets automatically before any transaction executes. Smart contracts deployed across multiple blockchains maintain a queryable registry of flagged addresses categorized by risk type and assigned ban periods ranging from twelve hours to permanent. DeFi protocols integrate these contracts into their own logic and query them before executing user transactions, allowing coordinated, trustless responses to emerging threats without manual intervention from protocol teams. The oracle network sources intelligence from established blockchain analytics firms including Chainalysis and Crystal Blockchain, relaying data to on-chain registries with minimal latency — the defining design constraint being that threat data must arrive faster than attackers can move funds. The Solana implementation is built on the Anchor framework and has accumulated over 500 commits on GitHub. CertiK and Hacken have both completed security audits of the protocol, with CertiK assigning a score of 4.0.

MixBytes is a blockchain security firm providing smart contract audits, code reviews, and security consulting for DeFi protocols. Founded in 2017, it conducts full public audits, confidential code reviews, and ongoing security consulting for teams requiring continuous guidance rather than point-in-time assessments. With over 300 completed engagements across Ethereum-compatible chains, Polkadot, Substrate, and Solana, the firm maintains a public audit archive on GitHub with more than 500 stars. Each engagement follows a four-phase process: independent analysis with adversarial enumeration of attack vectors, re-audit verifying that implemented fixes are correct and do not introduce new issues, final deployment verification confirming mainnet contracts match the reviewed codebase, and optional continuous support for protocol upgrades. Clients work with a dedicated team of three senior full-time auditors who remain consistent across repeat engagements, with the firm's CTO reviewing all reports before delivery. Documented clients include Lido Finance, Yearn Finance, Aave, 1inch, and Curve Finance.

SlowMist offers white-box smart contract audits for Solana programs, reviewing source code for the full range of vulnerabilities specific to Solana's account model and execution environment. The firm's Solana-focused audit methodology covers account ownership validation, program ID and signer authentication, SPL token standard compliance, Program Derived Address legitimacy, and rent adequacy checks. SlowMist has audited over 1,500 smart contracts across multiple blockchains, accumulating extensive experience with real-world exploit patterns. The team publishes and actively maintains a Solana Smart Contract Security Best Practices guide on GitHub, making their audit findings accessible to the broader developer community and helping protocol teams build with fewer critical flaws from the outset.

Daemon Protocol operates a real-time threat detection system for Solana, scanning transactions and smart contracts for phishing addresses, malicious contract patterns, and behavioral anomalies that precede exploits or fraud. Its transaction graph mapping traces the flow of funds across wallet clusters to surface connections to known bad actors, while behavioral pattern analysis identifies unusual activity sequences that deviate from expected protocol interaction patterns. The vulnerability scanning layer covers both deployed contracts and pre-deployment code review, allowing developers to assess their programs before exposure to mainnet risk. The system maintains an evolving database of flagged addresses and contract signatures, cross-referencing new transactions against this dataset to provide early warning for protocols and users interacting with potentially compromised counterparties.
