--- name: solana description: 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. version: 0.2.0 author: Deniz Alagoz (gizdusum), enhanced by Hermes Agent license: MIT metadata: hermes: tags: [Solana, Blockchain, Crypto, Web3, RPC, DeFi, NFT] related_skills: [] --- # 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 ```bash 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.). ```bash 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. ```bash 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. ```bash 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). ```bash 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). ```bash 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. ```bash 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. ```bash 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. ```bash 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. --- ## Verification ```bash # Should print current Solana slot, TPS, and SOL price python3 ~/.hermes/skills/blockchain/solana/scripts/solana_client.py stats ```
