Key Points

  • EVM-QuestBench is a new benchmark designed to evaluate natural-language transaction code generation specifically for EVM-compatible blockchain environments, emphasizing execution accuracy and safety.
  • The benchmark includes 107 tasks, both atomic and composite, using dynamic evaluation methods where instructions and parameters are sampled and validated on a forked EVM chain with snapshot isolation.
  • Evaluation of 20 models on this benchmark revealed significant performance differences, highlighting challenges particularly in multi-step workflow completion versus single-action precision.
  • EVM-QuestBench's modular architecture facilitates rapid development of new tasks and improvements in transaction script generation evaluation.
  • The benchmark addresses a critical gap in current evaluations that often neglect execution accuracy, which is vital to prevent irreversible losses in on-chain transactions.

Abstract:Large language models are increasingly applied to various development scenarios. However, in on-chain transaction scenarios, even a minor error can cause irreversible loss for users. Existing evaluations often overlook execution accuracy and safety. We introduce EVM-QuestBench, an execution-grounded benchmark for natural-language transaction-script generation on EVM-compatible chains. The benchmark employs dynamic evaluation: instructions are sampled from template pools, numeric parameters are drawn from predefined intervals, and validators verify outcomes against these instantiated values. EVM-QuestBench contains 107 tasks (62 atomic, 45 composite). Its modular architecture enables rapid task development. The runner executes scripts on a forked EVM chain with snapshot isolation; composite tasks apply step-efficiency decay. We evaluate 20 models and find large performance gaps, with split scores revealing persistent asymmetry between single-action precision and multi-step workflow completion. Code: this https URL.
