Skill Introduction

Overview

Query Solana blockchain data with USD pricing — wallet balances, token portfolios with values, transaction details, NFTs, whale detection, and live network stats. Uses Solana RPC + CoinGecko. No API key required.

Core value

Turns reusable Testing know-how into an installable skill, helping users complete github, community, ai, ai-agent work faster.

Target users

Developers, testers, and maintainers who handle Testing tasks in Focus Code.
Teams that already trust workflows or content from NousResearch.
Users who want standardized prompts, steps, or conventions instead of repeating setup work.

Best practices

Read the skill content first to confirm required inputs, expected outputs, and dependencies.
Try it on a small task before relying on it for critical work.
Add project-specific constraints such as coding style, target platform, test expectations, and delivery format.
For external sources, verify the source link, version, and recent maintenance activity.

Best use cases

Tasks related to github, community, ai, ai-agent that need a reusable execution flow.
Converting a community repo, team convention, or personal workflow into day-to-day assistance.
Starting from a proven skill instead of writing prompts or procedures from scratch.

Limits and boundaries

Results depend on the quality of the original skill content and may need human correction.
It does not replace code review, tests, security review, or professional judgment.
External tools, APIs, account permissions, and local dependencies still need separate setup.

Differentiation

Structured around Testing, making it easier to discover and reuse than loose prompt snippets.
Marked as GitHub, which helps users judge trust and maintenance expectations.
Keeps the original source link available for repository, documentation, or discussion follow-up.
Tagged with github, community, ai, ai-agent, so it can be filtered by concrete task intent.

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.

Quick Reference

RPC endpoint (default): https://api.mainnet-beta.solana.com Override: export SOLANA_RPC_URL=https://your-private-rpc.com

Helper script path: ~/.hermes/skills/blockchain/solana/scripts/solana_client.py

python3 solana_client.py wallet   <address> [--limit N] [--all] [--no-prices]
python3 solana_client.py tx       <signature>
python3 solana_client.py token    <mint_address>
python3 solana_client.py activity <address> [--limit N]
python3 solana_client.py nft      <address>
python3 solana_client.py whales   [--min-sol N]
python3 solana_client.py stats
python3 solana_client.py price    <mint_or_symbol>

Procedure

0. Setup Check

python3 --version

# Optional: set a private RPC for better rate limits
export SOLANA_RPC_URL="https://api.mainnet-beta.solana.com"

# Confirm connectivity
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py stats

1. Wallet Portfolio

Get SOL balance, SPL token holdings with USD values, NFT count, and portfolio total. Tokens sorted by value, dust filtered, known tokens labeled by name (BONK, JUP, USDC, etc.).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM

Flags:

--limit N — show top N tokens (default: 20)
--all — show all tokens, no dust filter, no limit
--no-prices — skip CoinGecko price lookups (faster, RPC-only)

Output includes: SOL balance + USD value, token list with prices sorted by value, dust count, NFT summary, total portfolio value in USD.

2. Transaction Details

Inspect a full transaction by its base58 signature. Shows balance changes in both SOL and USD.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  tx 5j7s8K...your_signature_here

Output: slot, timestamp, fee, status, balance changes (SOL + USD), program invocations.

3. Token Info

Get SPL token metadata, current price, market cap, supply, decimals, mint/freeze authorities, and top 5 holders.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  token DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263

Output: name, symbol, decimals, supply, price, market cap, top 5 holders with percentages.

4. Recent Activity

List recent transactions for an address (default: last 10, max: 25).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  activity 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM --limit 25

5. NFT Portfolio

List NFTs owned by a wallet (heuristic: SPL tokens with amount=1, decimals=0).

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  nft 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM

Note: Compressed NFTs (cNFTs) are not detected by this heuristic.

6. Whale Detector

Scan the most recent block for large SOL transfers with USD values.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py \
  whales --min-sol 500

Note: scans the latest block only — point-in-time snapshot, not historical.

7. Network Stats

Live Solana network health: current slot, epoch, TPS, supply, validator version, SOL price, and market cap.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py stats

8. Price Lookup

Quick price check for any token by mint address or known symbol.

python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price BONK
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price JUP
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price SOL
python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py price DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263

Known symbols: SOL, USDC, USDT, BONK, JUP, WETH, JTO, mSOL, stSOL, PYTH, HNT, RNDR, WEN, W, TNSR, DRIFT, bSOL, JLP, WIF, MEW, BOME, PENGU.

Pitfalls

CoinGecko rate-limits — free tier allows ~10-30 requests/minute. Price lookups use 1 request per token. Wallets with many tokens may not get prices for all of them. Use --no-prices for speed.
Public RPC rate-limits — Solana mainnet public RPC limits requests. For production use, set SOLANA_RPC_URL to a private endpoint (Helius, QuickNode, Triton).
NFT detection is heuristic — amount=1 + decimals=0. Compressed NFTs (cNFTs) and Token-2022 NFTs won't appear.
Whale detector scans latest block only — not historical. Results vary by the moment you query.
Transaction history — public RPC keeps ~2 days. Older transactions may not be available.
Token names — ~25 well-known tokens are labeled by name. Others show abbreviated mint addresses. Use the token command for full info.
Retry on 429 — both RPC and CoinGecko calls retry up to 2 times with exponential backoff on rate-limit errors.
