• Managing portfolio accumulation strategies

Prerequisites

1. Install OKX OnchainOS Skills

npx skills add okx/onchainos-skills

2. Get OKX API Credentials

Visit OKX OnchainOS Developer Portal:

• Connect your OKX Wallet

• Navigate to API Key management

• Create a new API Key

• Save the following credentials:

• OK-ACCESS-KEY (API Key)

• OK-ACCESS-SECRET (Secret Key)

• OK-ACCESS-PASSPHRASE (Passphrase)

3. Configure Environment Variables

Add credentials to your OpenClaw config:

Via openclaw.json (recommended):

Edit ~/.openclaw/openclaw.json :

{ "skills": { "entries": { "lazy-okx-dca": { "env": { "OKX_API_KEY": "your-api-key", "OKX_SECRET_KEY": "your-secret-key", "OKX_PASSPHRASE": "your-passphrase", "WALLET_PRIVATE_KEY": "your-wallet-private-key" } } } } }

Via .env file:

Create .env in project directory:

OKX_API_KEY=your-api-key OKX_SECRET_KEY=your-secret-key OKX_PASSPHRASE=your-passphrase WALLET_PRIVATE_KEY=your-wallet-private-key

Via shell profile:

Add to ~/.zshrc or ~/.bashrc :

export OKX_API_KEY="your-api-key" export OKX_SECRET_KEY="your-secret-key" export OKX_PASSPHRASE="your-passphrase" export WALLET_PRIVATE_KEY="your-wallet-private-key"

Run source ~/.zshrc to apply changes.

4. Verify Installation

Restart OpenClaw and test:

"What's the current price of ETH?"

Workflow

1. Receive DCA instruction ↓
2. Query OKX DEX API for optimal quote ↓
3. Display price estimate + slippage + fees ↓
4. Wait for user confirmation ↓
5. Construct transaction data ↓
6. Sign and broadcast (requires private key) ↓
7. Log transaction ↓
8. Wait for on-chain confirmation

Security Notes

• Private key storage: Keys stored locally only, never uploaded

• Test first: Use small amounts for initial testing (e.g., 1 USDC)

• Slippage settings: Increase during high volatility to avoid failed transactions

• Gas fees: Be aware of on-chain gas costs for small transactions

• Dedicated wallet: Use a separate wallet for DCA operations

DCA Psychology Tips

• Cost averaging: Buy less at highs, more at lows, lowering average cost

• Emotional stability: No need to watch markets, avoid FOMO and panic selling

• Long-term focus: Time in market beats timing the market

• Automation: Discipline matters more than timing
