When to Use This Skill

Use this skill when you need to:

• Query blockchain event logs, transactions, traces, instructions, Substrate events/calls, or trade fills
• Find the correct Portal dataset name for a blockchain
• Analyze on-chain activity (token transfers, DeFi events, contract deployments, trading)
• Use Portal MCP tools or the raw Stream API

Step 1: Find the Correct Dataset Name

Portal uses specific naming conventions that differ from common names.
