## What it does

The skill provides Python routines to inspect Solana token distribution. High concentration creates severe dump risks. The code computes top-N holder share, Gini coefficient, Herfindahl-Hirschman Index, and Nakamoto coefficient. If the top 10 wallets hold more than 80% of the supply, a few holders can crash the market immediately.

The routines also detect coordinated insider actions. Detection logic flags Jito bundles, snipers in opening blocks, and unrenounced mint or freeze authority. To run the analysis, you will need API keys for Helius DAS, SolanaTracker, or Birdeye because regular RPC calls only return 20 holders.

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill token-holder-analysis -a codex

gemini skills install https://github.com/agiprolabs/claude-trading-skills --path skills/token-holder-analysis
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/token-holder-analysis/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add agiprolabs/claude-trading-skills --skill token-holder-analysis -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- calculate top-N holder concentration on Solana
- compute Gini coefficient and HHI for token supply
- detect coordinated buyer bundles using Jito
- verify unrenounced mint and freeze authority flags

## Example prompts
- Analyze holder concentration for mint TOKEN_MINT using Helius
- Compute Gini coefficient and Nakamoto coefficient for these token holders
- Check this Solana token for Jito bundler activity and developer risk

# Token Holder Analysis — Concentration, Distribution & Risk

Analyze who holds a token, how concentrated ownership is, and whether insider patterns suggest risk. This is a critical pre-trade safety check — high concentration means a few wallets can crash the price.

## Quick Start

```python
import httpx
import math

# Using Helius DAS API for holder data
HELIUS_KEY = os.getenv("HELIUS_API_KEY", "")
HELIUS = f"https://mainnet.helius-rpc.com/?api-key={HELIUS_KEY}"

# Or using SolanaTracker for holder + risk data
ST_KEY = os.getenv("SOLANATRACKER_API_KEY", "")
ST = "https://data.solanatracker.io"

# Get top holders via RPC
def get_top_holders(mint: str) -> list[dict]:
    resp = httpx.post(HELIUS, json={
        "jsonrpc": "2.0", "id": 1,
        "method": "getTokenLargestAccounts",
        "params": [mint],
    })
    return resp.json()["result"]["value"]

holders = get_top_holders("TOKEN_MINT")
```

## Data Sources

| Source | What It Provides | Auth |
|--------|-----------------|------|
| **Solana RPC** (`getTokenLargestAccounts`) | Top 20 holders, supply | RPC key |
| **Helius DAS** (`getAsset`, token accounts) | Parsed holder data, metadata | API key |
| **SolanaTracker** (`/tokens/{t}/holders/top`) | Top 100 holders, bundler detection | API key |
| **Birdeye** (`/defi/token_security`) | Top 10 %, creator balance, freeze/mint auth | API key |

## Concentration Metrics

### Top-N Holder Percentage

The simplest measure — what % of supply do the top N holders control?

```python
def top_n_percentage(holders: list[dict], supply: int, n: int = 10) -> float:
    """Calculate percentage held by top N holders.

    Args:
        holders: Sorted list of holders (largest first).
        supply: Total token supply.
        n: Number of top holders.

    Returns:
        Percentage (0-100) held by top N.
    """
    top_n_amount = sum(int(h.get("amount", 0)) for h in holders[:n])
    return top_n_amount / supply * 100 if supply > 0 else 0
```

**Risk thresholds**:
- Top 10 < 30%: Well distributed
- Top 10 30-50%: Moderate concentration
- Top 10 50-80%: High concentration — significant dump risk
- Top 10 > 80%: Extreme — likely controlled by a few wallets

### Gini Coefficient

Measures inequality of token distribution (0 = perfectly equal, 1 = one holder owns everything).

```python
def gini_coefficient(amounts: list[float]) -> float:
    """Calculate Gini coefficient for holder distribution.

    Args:
        amounts: List of holder amounts (any order).

    Returns:
        Gini coefficient between 0 and 1.
    """
    if not amounts or all(a == 0 for a in amounts):
        return 0.0
    sorted_amounts = sorted(amounts)
    n = len(sorted_amounts)
    cumsum = sum((i + 1) * a for i, a in enumerate(sorted_amounts))
    total = sum(sorted_amounts)
````
