What is blockscout-ai marketplace?

A plugin collection for AI-assisted blockchain work using Blockscout, a service for exploring blockchain transactions, accounts, contracts, and tokens. It includes tools for analyzing blockchain data and building web3 software.

Analyzing wallets, addresses, contracts, transactions, tokens, and decentralized-finance data, or building web3 apps, scripts, command-line tools, and bots.

Blockchain data is spread across networks and can be difficult to query consistently. The collection provides documented ways to use the Blockscout API and related workflows.

Security

Grade A, and why

blockscout-ai marketplace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
