CryptoBench: A Dynamic Benchmark for Expert-Level Evaluation of LLM Agents in Cryptocurrency

Abstract: This paper introduces CryptoBench, the first expert-curated, dynamic benchmark designed to rigorously evaluate the real-world capabilities of LLM agents in the uniquely demanding and fast-paced cryptocurrency domain. Unlike general-purpose agent benchmarks for search and prediction, professional crypto analysis presents specific challenges: \emph{extreme time-sensitivity}, \emph{a highly adversarial information environment}, and the critical need to synthesize data from \emph{diverse, specialized sources}, such as on-chain intelligence platforms and real-time Decentralized Finance (DeFi) dashboards. CryptoBench thus serves as a much more challenging and valuable scenario for LLM agent assessment. To address these challenges, we constructed a live, dynamic benchmark featuring 50 questions per month, expertly designed by crypto-native professionals to mirror actual analyst workflows. These tasks are rigorously categorized within a four-quadrant system: Simple Retrieval, Complex Retrieval, Simple Prediction, and Complex Prediction. This granular categorization enables a precise assessment of an LLM agent's foundational data-gathering capabilities alongside its advanced analytical and forecasting skills. Our evaluation of ten LLMs, both directly and within an agentic framework, reveals a performance hierarchy and uncovers a failure mode. We observe a \textit{retrieval-prediction imbalance}, where many leading models, despite being proficient at data retrieval, demonstrate a pronounced weakness in tasks requiring predictive analysis. This highlights a problematic tendency for agents to appear factually grounded while lacking the deeper analytical capabilities to synthesize information.

• The paper presents CryptoBench, an expert-curated, dynamic benchmark designed to evaluate LLM agents in cryptocurrency analysis through multi-dimensional tasks.
• It employs real-time data integration from diverse platforms and a rigorous multi-stage verification protocol to simulate authentic crypto analytic workflows.
• Experimental results reveal a significant retrieval-prediction imbalance and highlight limitations in LLM architectures for complex inferential tasks.

CryptoBench: A Dynamic Benchmark for Expert-Level Evaluation of LLM Agents in Cryptocurrency

Introduction and Motivation

CryptoBench establishes a comprehensive evaluation paradigm for LLM agents in the high-volatility domain of cryptocurrencies, addressing limitations in general-purpose agent benchmarks. Existing datasets inadequately reflect the time-sensitivity, adversarial information environments, and cross-platform synthesis expected in professional crypto analysis. CryptoBench diverges from prior benchmarks by featuring monthly expert-curated tasks, integrating real-time data sources from diverse platforms, and categorizing evaluation across cognitive and operational dimensions.

Benchmark Architecture and Task Taxonomy

CryptoBench's architecture is underpinned by three pillars:

1. Expert Curation and Diversity: Tasks reflect authentic analyst workflows, spanning on-chain intelligence (whale activity, wallet profiling), market analytics (liquidations, open interest), DeFi protocol dashboards, DEX data aggregation, and MEV opportunities.
2. Dynamic Updating: Templated questions enable rapid modification of tokens, addresses, and timeframes, preventing contamination and ensuring continued relevance in a rapidly evolving market.
3. Broad Platform Integration: Each agent is compelled to navigate authoritative sources—leading on-chain aggregators, live DeFi dashboards, price feeds, and analytic sites—simulating the heterogeneous data integration performed by professional analysts.

Figure 1 presents the distribution of 50 monthly tasks, illustrating coverage across retrieval and prediction, simple and complex tasks.

Figure 1: Distribution of Task Types in CryptoBench demonstrates a balanced spectrum across retrieval/prediction and operational complexity.

Task taxonomy is formalized in the Four-Quadrant Classification System (Figure 2), enabling assessment not just of retrieval accuracy but also inferential and synthesizing competences.

Dataset Construction and Quality Control

CryptoBench leverages a rigorous multi-stage verification protocol (Figure 3), ensuring unambiguous, robust task designs. Expert authorship is followed by adversarial validation and senior adjudication, eliminating issues of source reliability and ambiguity. Temporal bounding and precision in metric definition are emphasized to mitigate noise and ambiguity endemic to real-time financial data.

Experimental Protocol

Ten state-of-the-art LLMs, both closed-source and open-source, are evaluated both directly and within an agentic framework (SmolAgent). Each model exclusively leverages a generalized web-browsing tool—no model had access to privileged APIs—ensuring a fair test of planning, tool orchestration, and data synthesis. Responses are scored on a 0–3 rubric leveraging an LLM-Judge protocol, incorporating correctness, precision tolerance ($\pm 5\%$ for numerical answers), and nuanced partial credit.

Results

The comprehensive evaluation uncovers a pronounced retrieval-prediction imbalance. Direct LLM evaluation (red bars) and agentic execution via SmolAgent (blue bars) reveal substantial discrepancies in success rates across models (Figure 4). Grok-4 (Web) leads in both paradigms, but retrieval-centric models frequently collapse on tasks requiring prediction, multi-step reasoning, and synthesis.

Figure 4: Combined Evaluation Scores indicate agentic execution significantly reorders model rankings and accentuates prediction weaknesses.

Fine-grained analysis by difficulty (Figure 5) and by quadrant (Figure 6) highlights a consistent drop in accuracy as task complexity or inferential demand increases. For instance, GPT-5 scores 58.8\% on Simple Retrieval yet drops below 7\% on Simple Prediction and Complex Prediction, indicating current LLM architectures struggle to transition from fact-finding to reasoning.

Figure 5: Task difficulty stratification reveals a marked performance drop between simple and complex tasks across models.

Figure 6: Performance by Task Quadrant substantiates the retrieval-prediction imbalance at both operational and cognitive complexity levels.

Macro-category performance (Figure 7) demonstrates another salient pattern: models are relatively competent in broad market analytics and less so in on-chain intelligence or DEX-specific domains.

Figure 7: Performance by Macro Category indicates distinct model strengths and consistent weaknesses in specialized crypto analytics.

Qualitative inspection identifies recurrent failure modes:

• Shallow Source Fidelity: Agents neglect authoritative real-time dashboards, defaulting to stale third-party blog posts.
• Stale Information: Cached or outdated values from previous market states frequently surface in responses.
• Integration Error: Agents retrieve relevant data points but fail in final synthesis or comparative judgment.
• Prediction Hallucination: Unsupported rationales and fabricated narratives in inferential tasks highlight a mismatch between retrieval ability and reasoning robustness.

Implications and Future Developments

The findings highlight fundamental limitations in current LLM agent architectures for crypto financial analysis. Strong data retrieval does not imply analytical competence, particularly in adversarial, fast-changing environments. The dynamic structure of CryptoBench exposes the limits of static knowledge and underscores the necessity for models capable of authentic synthesis, causal reasoning, and robust tool-use.

These results suggest several directions for future AI research:

• Development of domain-specific prediction modules that integrate real-time data feeds, pattern recognition, and adversarial awareness.
• Co-design of agentic frameworks and LLMs, optimizing interaction strategies with highly specialized platforms.
• Creation of hybrid systems coupling deep retrieval with causal reasoning pipelines, especially for domains exemplifying radical uncertainty and adversarial noise.

Conclusion

CryptoBench offers a dynamic, professionally validated environment for assessing the expert-level competence of LLM agents in cryptocurrency analysis. The detailed, quadranted evaluation uncovers a retrieval-prediction imbalance and significant shortfalls in tool use and inferential reasoning. The benchmark sets an agenda for the next generation of financial agent research, emphasizing dynamic updating, rigorous quality control, and authentic integration with adversarial real-world data sources. CryptoBench will serve as a critical resource for advancing domain-specific AI agents capable of robust operation in the most challenging information landscapes.
