A guide for querying and analyzing data from more than 130 blockchain networks, including transactions, events, traces, instructions, and other chain-specific records.

In plain words
What is it for?
Use it to find datasets, inspect token transfers or contract activity, analyze trades and deployments, or build longer-running data pipelines.
Why use it?
It helps choose between an interactive query, a raw data export, or a durable indexer when investigating blockchain activity.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

portal scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 483 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Portal

Query and analyze blockchain data across 130+ networks using SQD Portal. Use this skill to decide whether the job belongs in SQD Portal MCP tools, a raw Portal Stream API/curl request, or a durable Pipes/Squid indexer.

This skill should not be treated as a static copy of the MCP tool catalog. When the SQD Portal MCP server is available, read sqd://tools for the current grouped tool guide and sqd://tools/{tool_name} for exact per-tool guidance.

When to Use This Skill

Use this skill when you need to:

  • Query blockchain event logs, transactions, traces, instructions, Substrate events/calls, Bitcoin UTXOs, Tron transfers, or trade fills
  • Find the correct Portal dataset name for a blockchain
  • Analyze on-chain activity (token transfers, DeFi events, contract deployments, trading)
  • Choose between Portal MCP tools, raw Portal Stream API/curl, or a durable Pipes/Squid indexer

Use Portal MCP tools for bounded interactive answers, summaries, charts, investigation pivots, entity resolution, and normal chat-sized evidence.

Use raw Portal Stream API or curl when the user asks for raw rows, full exports, exact reproducible requests, NDJSON/CSV/files, or a query shape that should run outside the MCP client.

Recommend Pipes or a Squid when the user needs recurring sync, long backfills, joins, transformations, database storage, production APIs, alerts, dashboards, or app-owned indexed state.

Choose the Right SQD Surface

Need Use Why
Bounded answer in chat Portal MCP tools Best defaults, validation, normalized envelopes, pagination, freshness, and coverage notes
Network, entity, or tool discovery sqd://tools, sqd://datasets, discovery MCP tools Keeps routing current without duplicating catalogs
Raw rows or export Portal Stream API / curl Produces reproducible NDJSON and avoids chat preview truncation
Production data product Pipes / Squid Durable indexing, transforms, storage, retries, and serving APIs

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.
