Solana Blockchain Skill

Query Solana on-chain data enriched with USD pricing via CoinGecko. 8 commands: wallet portfolio, token info, transactions, activity, NFTs, whale detection, network stats, and price lookup.

No API key needed. Uses only Python standard library (urllib, json, argparse).

When to Use

• User asks for a Solana wallet balance, token holdings, or portfolio value
• User wants to inspect a specific transaction by signature
• User wants SPL token metadata, price, supply, or top holders
• User wants recent transaction history for an address
• User wants NFTs owned by a wallet
• User wants to find large SOL transfers (whale detection)
• User wants Solana network health, TPS, epoch, or SOL price
• User asks "what's the price of BONK/JUP/SOL?"

Prerequisites

The helper script uses only Python standard library (urllib, json, argparse). No external packages required.

Pricing data comes from CoinGecko's free API (no key needed, rate-limited to ~10-30 requests/minute). For faster lookups, use --no-prices flag.
