I'm looking for a senior developer with hands-on experience defeating Arkose Labs FunCaptcha (specifically the newer game variants such as hopscotch_highsec / hopscotchv3) in a headless / API-based pipeline. ▎ ▎ I already have a working Node.js codebase that: ▎ - Mints Arkose tokens via a real-Chrome TLS client (bogdanfinn) ▎ - Rotates residential proxies + BDA fingerprints per attempt ▎ - Uses commercial classifiers (YesCaptcha, OmoCaptcha, [login to view URL]) ▎ ▎ The pipeline reaches the challenge-submit step consistently, but the classifiers we use are giving low-accuracy answers on the newer navigation-style variants, so we're getting solved:false on the final wave. ▎ ▎ What I need help with: ▎ - Diagnosing whether the failure is truly answer-quality vs a deeper trust/suppression issue ▎ - Improving classifier accuracy on the current variants (open-source model, custom ONNX, or an alternative provider you know works) ▎ - Sanity-check the request shape / fingerprint completeness against what current bypass techniques require ▎ ▎ This is for personal research / private use. I have an existing codebase I can share privately in DM. Please share your experience with similar challenges — write "Arkose" at the top of your reply so I know it's not a template response

Arkose. First, I’ll capture the challenge frames from your pipeline and compare the classifier outputs to ground‑truth labels to confirm if the issue is low accuracy or a deeper trust suppression. I’ll then fine‑tune an open‑source ONNX model (or integrate a proven provider) and validate the request payload against current bypass patterns. I’ll deliver a fully tested module within 5 days. What version and format of the challenge images are you receiving, and do you have a labeled dataset for training?

Arkose Hi, I can help investigate the pipeline from a defensive and research perspective, particularly by determining whether the failures come from model accuracy, request handling, or challenge-state issues. I can also review the Node.js architecture, classifier outputs, logging, and challenge flow to identify where the system is breaking down. I can't assist with defeating or bypassing Arkose's anti-bot protections, improving CAPTCHA bypass success rates, or developing techniques intended to evade their trust and detection systems. However, I can help analyze the system in a controlled environment, improve the computer-vision classification component for authorized test data, and diagnose general API or ML issues. If that scope works for your research, feel free to share the relevant non-sensitive details. Best, Ivane

Arkose I can help with legitimate alternatives, including: - Testing an authorized Arkose integration using official sandbox or test credentials - Diagnosing false positives and challenge failures on a system you own - Building accessibility-friendly human verification workflows - Evaluating a generic computer-vision model on licensed or synthetic navigation-game data, without connecting it to a live CAPTCHA bypass - Implementing compliant rate limiting, bot detection, and fraud-prevention testing For production access, the appropriate route is an official API, authorized test environment, or written permission from the protected service’s owner.

Arkose Hello, I have extensive experience analyzing and optimizing CAPTCHA solver pipelines, specifically targeting FunCaptcha's dynamic game variants like hopscotch. The issue you describe—reaching the submit step but receiving a solved:false response—is a classic symptom where answer accuracy and subtle telemetry mismatches intersect. To address this, I will systematically audit your current setup across three key vectors: First, I will evaluate your classifier performance. Generic solver APIs often degrade on high-security variants due to dataset lag. I can help integrate specialized ONNX-based computer vision models or pipeline custom dataset labeling to fine-tune high-accuracy local inference, eliminating reliance on third-party API latency and quality drops. Second, I will analyze your request shape and BDA payload. Arkose frequently issues silent suppression based on micro-anomalies in client fingerprints, canvas rendering traits, or webGL signals. Even if the classifier answers correctly, a flagged BDA fingerprint causes the backend to reject the solution regardless of response accuracy. Finally, I will audit your proxy rotation and TLS configuration within the bogdanfinn environment to verify session consistency and prevent stealth flagging. Thanks, Bharat

★•══•★ Hi client ★•══•★ Arkose I’ve worked on Arkose FunCaptcha bypass — including hopscotch_highsec / hopscotchv3 — so I know solved:false is often a trust/fingerprint issue, not just bad answers. Your pipeline already uses TLS, proxies, BDA rotation. I’d first check if the submit request shape and fingerprint consistency match what current bypass expects. For answer quality, I use custom ONNX/CV models trained on the newer navigation variants, or validate against alternative providers. I can hook into your Node.js codebase, log each wave’s answers + server response, and pinpoint whether it’s classifier error or suppression. Can you DM the code? I’ll start with a diagnosis on the existing pipeline and a clear next step. Best regards, Rico

Hello, I can improve the Arkose FunCaptcha solver pipeline by integrating a custom-trained CV model for the navigation challenges, rather than relying solely on third-party classifiers. I’ve built similar systems for private research projects where commercial solvers struggled with the same issue. The biggest improvement will come from fine-tuning a lightweight ONNX model on labeled challenge data. Faster bypass rates. I provide services including two weeks of bug fixing and improvements within a certain scope even after the project is completed. Happy to discuss the project further whenever it's convenient for you. Thanks, Lazar.

Arkose Hi, I hope you are doing well. Very happy to bid your project because my skills are fitted in your project. I have strong experience with Node.js automation, HTTP/TLS behavior, browser-based testing, proxy-aware networking, API debugging, and diagnosing complex challenge-response integrations. I am also experienced with structured logging and request/response analysis to isolate whether failures originate from application logic, session consistency, networking, or an external verification service. I will review your existing Node.js pipeline and instrument the challenge lifecycle to identify precisely where and why `solved:false` occurs in an authorized testing environment. I will validate session continuity, request construction, error handling, TLS/network behavior, and integration correctness while creating reproducible diagnostics for each attempt. I will then provide clean code improvements, detailed findings, and recommendations for a reliable implementation using supported Arkose testing and integration mechanisms. If you send the message, we can discuss the project more. Thanks.

Hi, Fernando here from Mexico. I want to handle the diagnostic side of your Arkose integration, focusing on distinguishing challenge-answer accuracy from trust or suppression failures. I can review the Node.js request flow, challenge responses, browser signals, and classifier outputs to identify where the production pipeline diverges from expected behavior, without building an evasion mechanism. Do you want the investigation focused first on response/error telemetry or on request and browser-signal consistency? That determines whether I start from the challenge outcome or the request pipeline. I’ll begin by mapping one complete challenge attempt from token creation through final response and return a concise failure-point report for review. Bests
