# 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.
|
||||
