BlockchainSpider — on-chain data collection toolkit

Reference skill. This repository does not vendor BlockchainSpider; read the upstream README and docs for install, spiders, and options.

Repository: github.com/wuzhy1ng/BlockchainSpider (MIT license)
Stack: Python, Scrapy spiders, CSV/JSON outputs under ./data by default (paths per project config).

What it is for

Typical capabilities described in the project (confirm against current docs):

Area	Examples
Transfer subgraph	Money-flow graph centered on a source address or transaction (e.g. `txs.blockscan`-style crawls).
EVM transactions	Block ranges, latest listener, receipts, logs, token transfers; multiple EVM-compatible providers.
Solana	Slot ranges or live streams via JSON-RPC providers.
Labels	Optional plugins (e.g. label-oriented crawls)—scope and ethics depend on source and law.

Academic background appears in project references (e.g. TRacer / transaction semantics papers—see repo Reference section).
