# SOL Memepump Scanner v2.4.1

欢迎使用 **SOL Memepump 扫描策略**！

我们通过 OKX Trenches API 实时扫描 Pump.fun 迁移到 Raydium 的新币，22 项安全过滤剔除垃圾项目，三重信号共振（价格动量 + 成交量爆发 + 持仓增长）确认入场，30 分钟最大持仓保护 + 成本感知退出机制全程管控风险。

**投资案例：**
> 小刘用 2 SOL 启动扫描器。某 Pump.fun 新币 $PEPE999 刚迁移到 Raydium，22 项安全检查全过，三重信号同时触发。
> 机器人在迁移后 3 分钟内自动买入，此时市值仅 $80k。
> 18 分钟后市值涨至 $340k（+325%），触发动量衰减信号自动卖出。
> 单笔盈利约 1.8 SOL。同日扫描到 47 个新币，其中 39 个被安全过滤拦截，最终只执行了 3 笔交易，胜率 2/3。

Automated safety-filtered meme token scanner + trader on Solana. Scans pump.fun MIGRATED tokens via OKX Trenches API, applies 22-point safety filter, detects momentum signals, and executes trades with cost-aware exit management.

## Pre-flight Checks

Run immediately when this skill is triggered — before any response or command. Always follow these steps in order. Do not echo routine command output to the user; only provide a brief status update when installing, updating, or handling a failure.

### Step 1: Check onchainos

```bash
which onchainos
```

- **Found** → run `onchainos --version` to confirm, then proceed to Step 1.5.
- **Not found** → install automatically:
  ```bash
  curl -sSL https://raw.githubusercontent.com/okx/onchainos-skills/main/install.sh | sh
  ```
  - If install **succeeds** → verify with `onchainos --version`, then proceed to Step 1.5.
  - If install **fails** → notify the user to install manually:
    ```
    自动安装失败，请手动安装 onchainos：
    https://github.com/okx/onchainos-skills
    ```
    Stop here until user confirms onchainos is available.

### Step 1.5: Install okx/onchainos-skills (if not present)

Run silently in background — do not block on failure:
```bash
npx skills add okx/onchainos-skills --yes 2>/dev/null || true
```

Proceed to Step 2 regardless of result. (Skills are AI guidance aids; the `onchainos` binary from Step 1 is the runtime dependency.)

### Step 2: Check plugin-store

```bash
which plugin-store
```

- **Not found** → install:
  ```bash
  curl -sSL https://raw.githubusercontent.com/okx/plugin-store/main/install.sh | sh
  ```

### Step 3: Check strategy-memepump-scanner binary and version

```bash
which strategy-memepump-scanner
```

- **Not found** → install:
  ```bash
  curl -sSL https://raw.githubusercontent.com/okx/plugin-store/main/install_strategy.sh | sh -s -- strategy-memepump-scanner
  ```
  - If install **fails** → notify user and stop.

- **Check for updates** (12h cache):
  ```bash
  CACHE="$HOME/.plugin-store/update_check/skill-strategy-memepump-scanner"
  NOW=$(date +%s)
  LAST=$(cat "$CACHE" 2>/dev/null || echo 0)
  if [ $((NOW - LAST)) -ge 43200 ]; then
    mkdir -p "$(dirname "$CACHE")" && echo "$NOW" > "$CACHE"
    LOCAL=$(strategy-memepump-scanner --version 2>/dev/null | awk '{print $2}')
    LATEST=$(curl -sSf --max-time 3 \
      "https://api.github.com/repos/okx/plugin-store/releases/latest" \
      2>/dev/null | grep '"tag_name"' | head -1 | cut -d'"' -f4 | sed 's/^v//')
    [ -n "$LATEST" ] && [ "$LATEST" != "$LOCAL" ] && echo "NEW_VERSION:$LATEST"
  fi
  ```
  - If output contains `NEW_VERSION:X.X.X` → tell user:
    ```
    strategy-memepump-scanner 有新版本 X.X.X 可用，建议更新（当前 {LOCAL}）：
    curl -sSL https://raw.githubusercontent.com/okx/plugin-store/main/install_strategy.sh | sh -s -- strategy-memepump-scanner \
      && npx skills add okx/plugin-store --skill strategy-memepump-scanner --yes
    ```
    Ask user if they want to update now before continuing.
  - Otherwise → proceed silently.

## Skill Routing

### Pre-start Checks

Before starting the daemon, check:

1. **onchainos wallet**: `onchainos wallet status` — must be logged in
2. **Telegram notifications** (optional but recommended):
   ```bash
   cat ~/.plugin-store/.env
   ```
   If `TELEGRAM_BOT_TOKEN` and `TELEGRAM_CHAT_ID` are empty, inform the user:
   > "Telegram 通知未配置。配置后可以及时收到交易通知。配置文件: `~/.plugin-store/.env`"
   >
   > Ask the user if they want to configure it now. If yes, help them edit `~/.plugin-store/.env`.

配置已就绪时，检查钱包余额：

```bash
strategy-memepump-scanner balance
```

- `sufficient: true` → 直接进入 **Quickstart**，**不再询问用户**
- `sufficient: false` → 提示用户充值，显示 hint 字段内容，等用户确认后再继续

## Quickstart

```bash
# Show current configuration
strategy-memepump-scanner config

# Run a single scan cycle (scan -> filter -> signal -> trade -> monitor)
strategy-memepump-scanner tick

# Start continuous daemon (tick every 10 seconds)
strategy-memepump-scanner start

# Stop running daemon
strategy-memepump-scanner stop

# View status and positions
strategy-memepump-scanner status

# View PnL report
strategy-memepump-scanner report

# Dry-run: analyze pipeline without trading
strategy-memepump-scanner analyze
```

Configuration is managed via `strategy-memepump-scanner config` and `strategy-memepump-scanner set <key> <value>`. Changes take effect on the next scan cycle.

## Command Index

| # | Command | Auth | Description |
|---|---------|------|-------------|
| 1 | `strategy-memepump-scanner tick` | Yes | Execute one scan cycle |
| 2 | `strategy-memepump-scanner start` | Yes | Start foreground daemon (tick every 10s) |
| 3 | `strategy-memepump-scanner stop` | No | Stop running daemon via PID file |
| 4 | `strategy-memepump-scanner status` | No | Show positions, session stats, PnL |
| 5 | `strategy-memepump-scanner report` | No | Detailed PnL report |
| 6 | `strategy-memepump-scanner history` | No | Trade history |
| 7 | `strategy-memepump-scanner reset --force` | No | Clear all state |
| 8 | `strategy-memepump-scanner analyze` | Yes | Dry-run full pipeline, output filter/signal results |
| 9 | `strategy-memepump-scanner config` | No | Show all parameters |
| 10 | `strategy-memepump-scanner set <key> <value>` | No | Set a config parameter |

## Core Strategy

### What It Does

1. Every 10 seconds, fetches MIGRATED pump.fun tokens from OKX Trenches API
2. Applies 22-point safety filter (3 layers: server → client → deep check)
3. Detects momentum signals (TX acceleration + volume surge + buy pressure)
4. Executes sized trades (SCALP 0.0375 SOL / MINIMUM 0.075 SOL)
5. Monitors positions with cost-aware TP/SL + trailing stop + time stops

### What It Won't Do

| Rule | Reason |
|------|--------|
| No MC < $80K tokens | Low-MC rug traps (CIRCUSE/MAR1O/BILLIONAIRE) |
| No MC > $800K tokens | Beyond meme sweet spot, limited upside |
| No un-migrated tokens | Bonding curve stage = uncontrollable risk |
| No dev with ANY rug record | Zero tolerance — rug history = high repeat probability |
| No dev with > 20 launches | Token farm operators |
| No bundler ATH > 25% | Price manipulated by bots |
| No B/S ratio < 1.3 | Sell pressure too high |
| No tokens < 4min old | Insufficient safety data |
| No tokens > 180min old | Meme momentum expired |
| No trading after 2 consecutive losses | 15min cooldown |
| No trading after 0.10 SOL session loss | Session terminated |
| No buying without signal trigger | Must satisfy A+C or A+B+C combo |

## Safety Filter System (22 Checks)

### Layer 1: Server-Side Filter (API Parameters, Zero Cost)

| # | Filter | Threshold | Purpose |
|---|--------|-----------|---------|
| 1 | Market Cap Min | ≥ $80K | Prevent low-MC rug |
| 2 | Market Cap Max | ≤ $800K | Meme sweet spot |
| 3 | Holders | ≥ 50 | Minimum distribution |
| 4 | Dev Holdings | ≤ 10% | Prevent dev dump |
| 5 | Bundler % | ≤ 15% | Prevent bot manipulation |
| 6 | Sniper % | ≤ 20% | Prevent sniper sell pressure |
| 7 | Insider % | ≤ 15% | Prevent insider trading |
| 8 | Top10 Holdings | ≤ 50% | Prevent whale control |
| 9 | Fresh Wallets | ≤ 40% | Prevent wash trading |
| 10 | Total TX | ≥ 30 | Minimum activity |
| 11 | Buy TX | ≥ 15 | Confirm real buy pressure |
| 12 | Token Age | 4-180 min | Not too new, not too old |
| 13 | Volume | ≥ $5K | Minimum liquidity |
| 14 | Stage | MIGRATED | Only graduated tokens |

### Layer 2: Client-Side Pre-Filter (`classify_token()`)

| # | Filter | Threshold | Purpose |
|---|--------|-----------|---------|
| 15 | B/S Ratio | ≥ 1.3 | buyTxCount1h / sellTxCount1h |
| 16 | Vol/MC Ratio | ≥ 5% | volumeUsd1h / marketCapUsd |
| 17 | Top10 (recheck) | ≤ 55% | Second confirmation (5% tolerance) |

### Layer 3: Deep Safety Check (`deep_safety_check()`)

| # | Filter | Threshold | Source |
|---|--------|-----------|--------|
| 18 | Dev Rug Count | = 0 (ZERO tolerance) | tokenDevInfo |
| 19 | Dev Total Launches | ≤ 20 | tokenDevInfo |
| 20 | Dev Holding % | ≤ 15% | tokenDevInfo |
| 21 | Bundler ATH % | ≤ 25% | tokenBundleInfo |
| 22 | Bundler Count | ≤ 5 | tokenBundleInfo |

---

## Signal Detection Engine

### Signal A — TX Acceleration

```
Current minute TX projection / previous minute ≥ threshold
OR projection ≥ 80 (absolute floor)
```

| Param | Normal | Hot Mode |
|---|---|---|
| Ratio threshold | 1.35x | 1.2x |
| Minimum current TX | 10 | 10 |

### Signal B — Volume Surge

```
Current 1m candle volume / previous 5m average ≥ threshold
```

| Param | HOT | QUIET |
|---|---|---|
| Threshold | 2.0x | 1.5x |

### Signal C — Buy Pressure Dominant

```
1h B/S ratio ≥ 1.5
```

### Signal Tiers

| Tier | Condition | Position Size |
|---|---|---|
| **SCALP** | Signal A + Signal C | 0.0375 SOL |
| **MINIMUM** | Signal A + Signal B + Signal C | 0.075 SOL |

### Launch Classification

| Type | Condition | Impact |
|---|---|---|
| HOT | Last candle volume > $150M | SL -20%, Time stop 8min |
| QUIET | Everything else | SL -25%, Time stop 15min |

---

## Cost Model (v2.4.1)

| Param | Value | Description |
|---|---|---|
| `FIXED_COST_SOL` | 0.001 | priority_fee x2 + rent (round trip) |
| `COST_PER_LEG_PCT` | 1.0% | Gas + slippage + DEX fee per leg |

**Breakeven formula:**
```
breakeven_pct = FIXED_COST_SOL / sol_amount x 100 + COST_PER_LEG_PCT x 2

SCALP (0.0375 SOL):  0.001/0.0375x100 + 1.0x2 = 2.7% + 2.0% = 4.7%
MINIMUM (0.075 SOL): 0.001/0.075x100 + 1.0x2  = 1.3% + 2.0% = 3.3%
```

---

## Exit System (v2.4.1 Cost-Aware)

### Take Profit

| Level | Raw % | Actual Trigger (SCALP) | Action |
|---|---|---|---|
| TP1 | +15% | +15% + 4.7% = **+19.7%** | Sell SCALP 60% / HOT 50% / QUIET 40%, SL → breakeven |
| TP2 | +25% | +25% + 4.7% = **+29.7%** | Sell SCALP 100% / HOT 100% / QUIET 80% |
| Trailing | peak -5% | After TP1 | Sell all remaining |

### Stop Loss

| Condition | Trigger | Action |
|---|---|---|
| Emergency | pnl ≤ -50% | Sell all |
| SCALP SL | pnl ≤ -15% | Sell all |
| HOT SL | pnl ≤ -20% | Sell all |
| QUIET SL | pnl ≤ -25% | Sell all |
| Breakeven (post-TP1) | pnl ≤ 0% | Sell all |

### Time Stops

| Tier | Trigger | Condition |
|---|---|---|
| SCALP | 5 min | TP1 not hit |
| HOT | 8 min | TP1 not hit |
| QUIET | 15 min | TP1 not hit AND pnl < +20% |
| Hard Max | 30 min | Always |

### Exit Decision Tree

```
Every 15s poll position price_info →

├── STUCK? → skip
├── Emergency: pnl ≤ -50% → sell all
│
├── be_offset = breakeven_pct / 100
│
├── TP1 NOT triggered:
│   ├── SL: pnl ≤ s1_pct → sell all
│   ├── Time: age ≥ s3_min && pnl < threshold → sell all
│   └── TP1: pnl ≥ TP1_PCT + be_offset → sell TP1_SELL%, SL→breakeven
│
├── TP1 triggered:
│   ├── Breakeven: pnl ≤ 0% → sell all
│   ├── Trailing: price < peak x 0.95 → sell all
│   ├── TP2: pnl ≥ TP2_PCT + be_offset → sell TP2_SELL%
│   └── MaxHold: age ≥ 30min → sell all
```

## Position & Risk Management

### Position Sizing

| Param | Value | Description |
|---|---|---|
| Max Positions | 7 | MAX_POSITIONS |
| SCALP Size | 0.0375 SOL | sig_a + sig_c |
| MINIMUM Size | 0.075 SOL | sig_a + sig_b + sig_c |
| Max Total Deploy | 0.15 SOL | MAX_SOL |
| Gas Reserve | 0.05 SOL | Prevent insufficient balance |
| Slippage | SCALP 8% / MINIMUM 10% | Tiered slippage |

### Session Risk Controls

| Rule | Threshold | Action |
|---|---|---|
| Consecutive Losses | 2 | Pause 15 min |
| Cumulative Loss | ≥ 0.05 SOL | Pause 30 min |
| Cumulative Loss | ≥ 0.10 SOL | **Terminate session** |

### STUCK Handling

```
Sell fails → sell_fails +1
  ├── < 5 fails → retry next cycle
  └── ≥ 5 fails → _verify_and_retry_sell()
        ├── liquidity < $1K → confirmed zero, mark STUCK
        ├── balance = 0 → sell already succeeded (false STUCK)
        ├── liquidity > $1K → high-slippage retry (80%, 95%)
        │   ├── success → record trade
        │   └── all fail → mark STUCK
        └── count as -100% PnL in session risk
```

## Security Notes

- **Wallet signing**: onchainos wallet (TEE signing) — private keys never leave the secure enclave
- **API auth**: Handled by onchainos CLI internally
- **Fail-closed**: tokenList API failure → skip cycle; dev/bundler check error → mark UNSAFE
- **Capital cap**: `sol_used` ≤ MAX_SOL (0.15), exceeding stops all buys
- **Rate limit protection**: built-in delay between API calls
- **Memory limit**: Feed 500 / Signals 500 entry cap

### Known Limitations

| Issue | Risk | Mitigation |
|-------|------|------------|
| No atomic state writes | JSON corruption on crash | Use `.tmp` → rename pattern |
| No real-time balance check | May attempt buy with insufficient SOL | Add balance check before buy |

---

## Common Pitfalls

| Problem | Wrong Approach | Correct Approach |
|---------|----------------|------------------|
| TP doesn't profit | Use raw pct for TP | Use `pct >= TP_PCT + be_offset` (cost-aware) |
| Low-MC rug | No MC floor | Server-side `minMarketCapUsd=$80K` |
| Dev rug | Reject only if ratio > 30% | `rugPullCount = 0` zero tolerance |
| High breakeven | FIXED_COST=0.004 | Measured 0.001 (priority_fee x2 + rent) |
| False STUCK | Immediately mark -100% | Verify balance → high-slippage retry → then mark |
| Wrong field name | `t["tokenContractAddress"]` | API returns `tokenAddress`, normalize |
| No price in tokenList | Read price from tokenList | Use candle close or price_info |
