USDC Auto-Rebalance Daemon

欢迎使用 USDC 智能调仓策略！

我们帮你自动在 Aave V3、Compound V3、Morpho 三个协议之间轮动 USDC，始终把资金放在当前收益最高的地方，无需手动盯盘。策略内置 TVL 安全监控、Gas 熔断、24 小时冷却等保护机制，稳定币零币价风险。

投资案例：

小王有 10,000 USDC 闲置。他启动了自动调仓守护进程，设置最小利差 0.3%。 第一天：Aave 年化 4.2%，自动存入 Aave。 第 5 天：Morpho 年化涨到 5.8%，利差 1.6% > 0.3%，自动转仓到 Morpho。 30 天后：综合年化约 5.1%，较手动管理多赚约 $35，全程零操作。

3 commands for automated USDC yield optimization across Aave V3, Compound V3, and Morpho on Base and Ethereum mainnet.

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

which onchainos

• Found → run onchainos --version to confirm, then proceed to Step 2.
• Not found → install automatically:

  curl -sSL https://raw.githubusercontent.com/okx/onchainos-skills/main/install.sh | sh
  

  • If install succeeds → verify with onchainos --version, then proceed to Step 2.
  • 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 2: Check skills-store

which skills-store

• Not found → install:

  curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install.sh | sh
  

• Check for updates: Read ~/.cargo/bin/.skills-store/last_check_auto_rebalance and compare with current timestamp:

  cached_ts=$(cat ~/.cargo/bin/.skills-store/last_check_auto_rebalance 2>/dev/null || true)
  now=$(date +%s)
  

  • If cached_ts is non-empty and (now - cached_ts) < 43200 (12 hours), skip the update.
  • Otherwise, run the installer to check for updates.

Step 3: Check strategy-auto-rebalance

which strategy-auto-rebalance

• Found → proceed.
• Not found → install:

  curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install_strategy.sh | sh -s -- strategy-auto-rebalance
  

  • If install succeeds → verify with strategy-auto-rebalance --version, then proceed.
  • If install fails → notify the user:

    自动安装失败，请手动安装 strategy-auto-rebalance：
    curl -sSL https://raw.githubusercontent.com/purong-huang-1121/skills-store/main/install_strategy.sh | sh -s -- strategy-auto-rebalance
    

    Stop here until user confirms installation.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

自动在 Aave V3 / Compound V3 / Morpho 之间轮动，
始终将 USDC 放在收益最高的协议里。

📌 投资案例：
  10,000 USDC，30 天，设最小利差 0.3%
  综合年化约 5.1%，较手动多赚 ~$35，全程零操作。

支持链：Base（推荐）/ Ethereum
预估年化：3%~8%

需要 onchainos 钱包登录后才能运行。

Pre-start Checks

Before starting the daemon, check:

1. onchainos wallet: onchainos wallet status — must be logged in
2. Telegram notifications (optional but recommended):

   cat ~/.cargo/bin/.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: ~/.cargo/bin/.env"

   Ask the user if they want to configure it now. If yes, help them edit ~/.cargo/bin/.env.

然后询问用户选择链（Base / Ethereum）。

Pre-Start Confirmation

IMPORTANT: Before executing strategy-auto-rebalance start, you MUST present the following summary to the user and ask for explicit confirmation. Do NOT start the daemon until the user approves.

Display a table like this:

Ready to start Auto-Rebalancer. Please confirm:

  Chain:           Base (8453)
  Interval:        300s (5 min)
  Min Spread:      0.50%
  Max Break-even:  7 days
  Protocols:       Aave V3, Compound V3, Morpho
  Telegram:        Enabled / Disabled
  Wallet:          0xf6e7...4572

  Gas threshold:   5 gwei (Base) / 50 gwei (Ethereum)
  TVL alert:       20.0% (configurable, non-blocking)
  TVL emergency:   Emergency withdraw if TVL drops >30%
  State file:      ~/.skills-store/auto-rebalance-state.json

Proceed? (y/n)

Key points to verify:

• Wallet address from onchainos wallet — confirm it's the intended wallet
• Chain — confirm it matches user intent (Base vs Ethereum have very different gas costs)
• Interval — explain what it means in practical terms ("checks every X minutes")
• Min spread — lower = more frequent rebalancing; higher = fewer but more meaningful moves
• If wallet has idle USDC (not deposited in any protocol), the daemon will auto-deposit into the best protocol on its first cycle

Skill Routing

• For single-protocol Aave operations → use skills-store aave
• For Morpho vault operations → use skills-store morpho
• For grid trading → use strategy-grid-trade
• For prediction markets → use skills-store polymarket / skills-store kalshi
• For perpetual trading → use skills-store hyperliquid

Prerequisites

1. onchainos CLI: Must be installed and logged in. Verify:

   onchainos --version   # >= 1.0.5
   onchainos wallet status  # must show loggedIn: true
   

   If not installed, follow: https://okg-block.sg.larksuite.com/docx/Cx7PdgNHLogZWIxGlwslfacIgl1

2. Telegram notifications (optional): Configure in ~/.cargo/bin/.env:

   TELEGRAM_BOT_TOKEN=your_bot_token
   TELEGRAM_CHAT_ID=your_chat_id
   

Authentication

• EVM Wallet: onchainos wallet (TEE signing) — no private key needed in .env
• OKX API: Handled by onchainos CLI internally

Multi-Chain Support

Base has low gas (~$0.001-0.05 gwei per tx, $0.01-0.03 cost), so shorter intervals and lower spread thresholds make sense. Ethereum gas is much higher ($1-5), so longer intervals and stricter thresholds are recommended.

Rebalance cooldown: Regardless of interval, the daemon enforces a 24-hour minimum between rebalances to prevent excessive trading from APY fluctuations.

Quickstart

# Base — low gas, check every 5 minutes, rebalance if spread > 0.3%
strategy-auto-rebalance start --chain base --interval 300 --min-spread 0.3

# Ethereum — higher gas, check every hour, rebalance if spread > 1.0%
strategy-auto-rebalance start --chain ethereum --interval 3600 --min-spread 1.0

# With Telegram notifications
strategy-auto-rebalance start --chain base --interval 300 --min-spread 0.3 \
  --telegram-token <BOT_TOKEN> --telegram-chat <CHAT_ID>

# Check daemon status
strategy-auto-rebalance status

# Stop daemon
strategy-auto-rebalance stop

Command Index

CLI Command Reference

strategy-auto-rebalance start

strategy-auto-rebalance start [--chain <chain>] [--interval <seconds>] [--min-spread <pct>] [--max-break-even <days>] [--tvl-alert-threshold <pct>] [--telegram-token <token>] [--telegram-chat <id>]

Recommended configurations:

Daemon capabilities:

• Periodic yield checks across Aave V3, Compound V3, and Morpho
• Smart decision engine: Hold / Rebalance / Emergency Withdraw
• Auto-deposit: If wallet has idle USDC and no protocol position, deposits into the best protocol automatically
• Dynamic vault discovery: Morpho vault selection via GraphQL API — picks the highest APY vault with TVL > $100k
• TVL safety monitoring — median-based comparison triggers emergency withdraw if TVL drops >30%
• Gas spike circuit breaker — pauses when gas exceeds chain threshold
• Telegram notifications (🤖 Auto-Rebalancer) for all events
• State persistence at ~/.skills-store/auto-rebalance-state.json
• PID management — prevents duplicate instances

strategy-auto-rebalance stop

Sends SIGTERM to the running daemon via PID file (~/.skills-store/auto-rebalance-daemon.pid).

strategy-auto-rebalance status

Shows daemon status: running/stopped, config, current position (protocol + APY + balance), last check time, rebalance history.

Decision Logic

Each cycle, the daemon:

1. Fetch yields — queries Aave V3 (on-chain), Compound V3 (on-chain), Morpho (GraphQL). Falls back to DeFiLlama if on-chain fails.
2. Safety check — TVL tracking (median of recent vs earlier entries), gas spike detection.
   • TVL drop >20% → alert notification (non-blocking)
   • TVL drop >30% → emergency withdrawal
3. Detect capital — if in a protocol, reads protocol balance; if idle, reads wallet USDC balance.
4. Frequency guard — enforces 24-hour minimum between rebalances to prevent excessive trading.
5. Decide:
   • Emergency Withdraw — if current protocol's TVL dropped >30% (median comparison)
   • Hold — if gas spiking, cooldown active, already in best protocol, spread too small, or break-even too long
   • Rebalance — withdraw from current → deposit into best; or initial deposit from wallet if protocol=none
6. Execute — on-chain transactions (approve + withdraw + verify wallet balance + deposit + verify target balance), notify via Telegram.

Cross-Skill Workflows

Workflow A: Research → Start Daemon

1. skills-store aave markets --chain base             → check current Aave rates
2. skills-store morpho vaults --chain base            → see Morpho vault options
3. strategy-auto-rebalance start --chain base ...     → let the daemon auto-optimize

Workflow B: Check Status → Manual Intervention

1. strategy-auto-rebalance status                     → review position and PnL
2. skills-store morpho positions <address> --chain base → verify on-chain state
3. strategy-auto-rebalance stop                       → stop if needed

Workflow C: Multi-Chain

# Terminal 1
strategy-auto-rebalance start --chain base --interval 300 --min-spread 0.3

# Terminal 2
strategy-auto-rebalance start --chain ethereum --interval 3600 --min-spread 1.0

Note: each chain uses the same PID file, so only one daemon instance can run at a time. For multi-chain, run in separate terminals with separate working directories, or stop one before starting the other.

Key Concepts

• APY: All rates are APY (compound formula from on-chain rate per second × seconds per year).
• Break-even: Days for yield improvement to cover gas costs. Formula: gas_cost / (capital × spread% / 365). Lower = better.
• TVL monitoring: Tracks protocol TVL using median of recent vs earlier entries (not single-point comparison). Requires at least 3 data points. A drop exceeding tvl_alert_threshold (default 20%, configurable) triggers a non-blocking alert; >30% triggers emergency withdrawal. History capped at 96 entries (~24h at 15min intervals).
• Gas circuit breaker: Base threshold 0.5 gwei, Ethereum 50 gwei. Exceeding pauses all trading.
• Rebalance cooldown: 24-hour minimum between rebalances, regardless of check interval. Prevents excessive trading from short-term APY fluctuations.
• Post-execution verification: After withdrawal, verifies wallet received USDC before proceeding to deposit. Aborts if wallet balance is zero.
• Yield sources: Aave V3 (lending pool on-chain), Compound V3 (Comet on-chain), Morpho (ERC-4626 vaults via GraphQL — dynamically discovers the best USDC vault with TVL > $100k).
• DeFiLlama fallback: If on-chain APY fetch fails, DeFiLlama pool data is used as fallback.
• Auto-deposit: When the daemon detects wallet USDC but no active protocol position, it deposits directly into the best-yielding protocol (deposit-only, no withdrawal step).
