MoTS — transaction semantic representation (research codebase)

Reference skill. Upstream states that MoTS is merged into BlockchainSpider—prefer the BlockchainSpider documentation for current spiders and maintenance. This skill documents the standalone MoTS repository for paper reproduction, historical commands, and skill discovery.

• Repository: github.com/wuzhy1ng/MoTS
• Paper (in repo): MoTS_WWW_2023_manuscript.pdf — Know Your Transactions: Real-time and Generic Transaction Semantic Representation on Blockchain & Web3 Ecosystem (ACM WWW 2023).

What the standalone repo implements

Step	Spider (examples from upstream README)	Role
Acquisition	blocks.eth	Collect txs from RPC over block ranges; types can include external, internal, erc20, erc721, erc1155.
Semantics	blocks.semantic.eth	Same shape of inputs plus transaction semantic vectors (per upstream description).
Labels	labels.action	Transaction semantics labels sourced via Etherscan-class APIs (block-range oriented in examples).

Storage: outputs under ./data (per upstream README). Config: upstream points to APIKEYS, PROVIDERS, and CONCURRENT_REQUESTS in settings.py.

Install (clone upstream)

The dependency file is named requiremets.txt in the repository (upstream spelling). After clone:

pip install -r requiremets.txt

Confirm the filename on the branch you use—it may be renamed in a future commit.

Example command shapes (placeholders only)

# Block-range acquisition (replace RPC and range; confirm spider names in upstream README)
scrapy crawl blocks.eth -a start_blk=<N> -a end_blk=<M> -a types=external,internal,erc20,erc721,erc1155

# Semantic vectors + data (same placeholders)
scrapy crawl blocks.semantic.eth -a start_blk=<N> -a end_blk=<M> -a types=external,internal,erc20,erc721,erc1155

# Label-oriented crawl (Etherscan-class API key must be set per settings)
scrapy crawl labels.action -a start_blk=<N> -a end_blk=<M>

If end_blk is omitted in upstream examples, collection may follow the chain tip—mind RPC cost and rate limits.

How to combine with blockint

Task	Skill
Current Scrapy toolkit, Solana + EVM breadth	blockchain-spider-toolkit (BlockchainSpider)
Analytics / AML framing of “transaction meaning”	blockchain-analytics-operations
EVM DeFi triage	evm-solidity-defi-triage-agent

Guardrails

• Prefer BlockchainSpider for new work if upstream merge note still applies—avoid duplicating unmaintained forks.
• Configure your own APIKEYS and PROVIDERS; never commit or paste live keys.
• Respect Etherscan (and similar) ToS and rate limits; semantic labels are research artifacts, not compliance verdicts.
• Lawful use only; outputs are not a substitute for licensed analytics or legal conclusions.

Goal: a discoverable pointer to MoTS and its relationship to BlockchainSpider for blockint users researching transaction semantics and KYT-style representations.
