Introduction

Overview

Cyfrin is a specialized blockchain security firm that combines world-class smart contract audits, developer tooling, and educational resources to help protocols, teams, and individual developers secure on-chain systems. Their approach blends manual expert review with automated tooling and community-driven competitive audits to reduce vulnerability risk across multiple chains. Cyfrin serves enterprise clients, DeFi protocols, and developer communities with services and platforms intended to improve code security, developer skill, and operational trust.

Core capabilities

  1. Smart Contract Audits: Deep manual reviews by senior security researchers to identify logic flaws, reentrancy, access control issues, and attack vectors. Audits aim to both find critical vulnerabilities and offer actionable remediation guidance.

  2. Developer Tools: Automated tooling such as Aderyn (Solidity static analyzer) and Foundry DevOps integrations to surface vulnerabilities early in the development lifecycle and replicate deployment contexts for testing.

  3. Competitive Audit Platform (CodeHawks): A crowdsourced/competitive model that gives projects access to a vetted network of top auditors and researchers, increasing coverage and incentive-aligned vulnerability discovery.

  4. Education & Training (Updraft): Hands-on courses and curricula covering Solidity, Foundry, smart contract security, and auditing techniques to elevate teams and individual engineers from novice to expert.

  5. Security Research Aggregation (Solodit): A research platform that aggregates vulnerabilities, bounties, contests, and resources across the security ecosystem to help teams learn from real incidents and improve defensive posture.

Platforms and tooling

Cyfrin’s product ecosystem is designed to cover the full security lifecycle:

  1. CodeHawks: Competitive audit workflow connecting protocols to multiple auditors for rapid and diverse review coverage.

  2. Aderyn: A static analysis engine that flags critical issues in Solidity codebases, formatted for developer consumption and triage.

  3. Foundry DevOps integrations: Tools and utilities for reproducing and interacting with historical deployments inside a Foundry environment for testing and debugging.

  4. Updraft: Educational pathways with practical labs and instructor-led content to train engineers in secure contract development and auditing.

  5. Solodit: A centralized research index capturing known vulnerabilities, bounty programs, and security findings to inform defensive strategies.

Why choose Cyfrin

  • Depth and seniority of expertise: Cyfrin highlights that its auditors and security researchers include industry veterans who have worked at well-known organizations and projects, bringing real-world attack and defense experience.

  • Multi-layered approach: Combining manual audits, automated analysis, competitive reviews, and continuous developer education provides broader coverage than any single method.

  • Cross-chain support: Cyfrin explicitly supports major chains and layer-2s, enabling teams working across ecosystems to adopt consistent security standards.

  • Trust and communication: Beyond finding bugs, audits are used to establish trust with users and stakeholders by demonstrating rigorous testing and best-practice alignment.

Recommended approach / Getting started

  1. Request an initial consultation or audit to scope the protocol and identify priority components.

  2. Use Aderyn and Foundry DevOps during development to catch issues early and reduce later remediation costs.

  3. Combine a formal Cyfrin audit with CodeHawks competitive reviews for high-value or high-risk contracts.

  4. Enroll engineering teams in Updraft courses to build internal auditing capacity and long-term resilience.

Conclusion

Cyfrin positions itself as an end-to-end partner for blockchain security: from automated detection and manual review to community-driven audits and developer education. For teams aiming to protect user funds, communicate maturity, and build secure products across chains, Cyfrin offers an ecosystem of services and tools intended to reduce vulnerability exposure and raise the baseline of on-chain safety.

    The page at /ltc-20 on litecoin.com returns a 404 “Page not found,” indicating the specific resource has been removed or relocated. Based on the URL and the host domain, the missing page was likely intended to describe “LTC-20,” a token-related concept or standard connected to the Litecoin ecosystem. LTC-20 can be understood generally as a fungible token specification or programmatic token layer intended to enable token issuance, transfer, and interaction on Litecoin-compatible infrastructure, helping projects launch tokens that integrate with wallets, explorers, and marketplaces. Although the original page content is unavailable, LTC-20 is commonly referenced as a way to expand Litecoin’s on-chain use cases, enabling developers and users to create tokens, manage supply, and improve compatibility across tooling and services.

    LTC-20 is presented as a token standard associated with the Litecoin project, intended to provide a fungible token interface analogous to ERC-20 on Ethereum. Although the specific GitHub repository at https://github.com/litecoin-project/ltc-20 currently returns a “Page not found” (404) on GitHub, the name implies a specification for minting, transferring, and managing tokens within the Litecoin ecosystem or compatible layers. The standard likely targets interoperability, simple transfer and allowance mechanics, and integration with wallets and explorers while remaining lightweight and aligned with Litecoin’s design principles. Because the original repository is unavailable, developers and integrators should seek official Litecoin Project channels, archived copies, or other authoritative sources before implementing or relying on the standard in production.

    Mempool (mempool.space) is a real-time blockchain explorer and mempool visualizer designed to provide detailed, up-to-the-second information about transactions, fees, and recent blocks for UTXO-based networks such as Bitcoin and Litecoin. The site aggregates mempool state, fee-rate estimates, transaction replacements (RBF), recent block listings, mining pool attribution, and various network metrics like difficulty and average block time, presenting them in a clear, interactive interface. Users can inspect individual transactions, view recommended fee rates for different confirmation targets, and monitor unconfirmed transaction counts and memory usage. For both casual users and advanced operators, Mempool offers a blend of high-level summaries and granular data that helps with fee selection, transaction tracking, and general chain monitoring.
