Multi-Agent Crypto Due Diligence on LangGraph

Multi-Agent Crypto Due Diligence on LangGraph

A multi-agent due-diligence system on LangGraph that researches crypto projects across on-chain data, GitHub activity, team signals and social channels — compressing 8 hours of analyst work into roughly 10 minutes.

01. Challenge

Crypto due diligence requires pulling together on-chain metrics, GitHub commit patterns, team backgrounds, tokenomics and community signals — work that typically takes an analyst the better part of a day.

We wanted to explore how far multi-agent orchestration could compress this, and to build a reference architecture for future client projects in the multi-agent space.

02. Solution

A LangGraph-orchestrated system of specialised agents — on-chain analyst, GitHub analyst, team analyst, social analyst, synthesiser — each with its own tools, retrieval scope and output schema.

A coordinator agent routes tasks, enforces budget limits, and assembles the final report with full source attribution.

03. Results

  • 8 hrs → 10 minThroughput
    Time to produce a structured due-diligence report
  • Multi-sourceSources
    On-chain, code, team, social, news in a single report
  • FullAttribution
    Every claim traceable to source and agent

04. Constraints

  • Sources are heterogeneous (on-chain APIs, GitHub, X, Discord, news, whitepapers)
  • Output must be auditable — every claim traced to a source
  • Agents must coordinate without infinite tool-loops or unbounded cost
  • Designed as a reference architecture for client multi-agent projects

05. Architecture

A coordinator graph in LangGraph dispatches sub-tasks to specialist agents, each with a narrow tool surface (on-chain APIs, GitHub API, search) and a typed output schema.

Intermediate results are stored in a shared scratchpad so agents can build on each other without re-fetching.

A synthesiser agent assembles the final report, with every claim linked back to the agent and the source it came from. Cost and tool-call budgets are enforced at the coordinator level.
