Installation

Prerequisites

• Node.js >= 18.0.0
• OpenClaw installed and configured
• evm-wallet-skill (recommended) - For wallet and RPC configuration

Quick Install

# 1. Install the plugin
openclaw plugins install amped-defi

# 2. Add to the plugin allow list
#    If you have NO existing allow list:
openclaw config set plugins.allow '["amped-defi"]' --json

#    If you ALREADY have plugins in your allow list, edit the config
#    to append "amped-defi" to the existing array:
#    openclaw config   (opens the config wizard)
#    — or edit ~/.openclaw/openclaw.json directly

# 3. Restart the gateway
openclaw gateway restart

⚠️ Allow list required: OpenClaw requires plugins to be explicitly added to plugins.allow in your config. Without this, the plugin will show as "disabled (not in allowlist)" and its tools won't load.

Verify with openclaw plugins list — the plugin should show as loaded.

Install from Source

If you prefer installing from source:

cd ~/.openclaw/extensions/amped-defi
npm install

Then add to the allow list and restart the gateway (steps 2–3 above).

Verify Installation

# List loaded plugins
openclaw plugins list

# Check for amped tools (should see 25 tools)
openclaw tools list | grep amped_

You should see tools like:

• amped_supported_chains
• amped_swap_quote
• amped_mm_supply
• amped_cross_chain_positions
• etc.

Updating the Plugin

openclaw plugins update amped-defi

Or reinstall manually:

openclaw plugins uninstall amped-defi
openclaw plugins install amped-defi

Uninstalling

openclaw plugins uninstall amped-defi

Troubleshooting Installation

"Cannot find module 'viem'" or similar errors:

cd ~/.openclaw/extensions/amped-defi
npm install

"plugin not found" after uninstall: Edit ~/.openclaw/openclaw.json and remove the amped-defi entry from plugins.entries.

Plugin not loading: Check OpenClaw logs for errors:

tail -f ~/.openclaw/logs/openclaw.log

Configuration

Wallet Setup (Optional)

The plugin works without a wallet for read-only operations (quotes, balances, discovery). To execute transactions, configure a wallet using one of the options below.

No wallet configured? The agent will prompt you to install evm-wallet-skill when you try to execute a transaction.

🔌 evm-wallet-skill Integration (Recommended)

Install evm-wallet-skill for self-sovereign wallet management:

git clone https://github.com/amped-finance/evm-wallet-skill.git ~/.openclaw/skills/evm-wallet-skill
cd ~/.openclaw/skills/evm-wallet-skill && npm install
node src/setup.js  # Generate a new wallet

The plugin automatically detects wallets from ~/.evm-wallet.json.

Supported chains: Ethereum, Base, Arbitrum, Optimism, Polygon, Sonic, LightLink, HyperEVM, Avalanche, BSC, MegaETH, and more.

Add custom chains via natural language:

"Add Berachain with chain ID 80094 and RPC https://rpc.berachain.com"

Or directly:

node src/add-chain.js berachain 80094 https://rpc.berachain.com --native-token BERA

The plugin will automatically detect and use:

• EVM_WALLETS_JSON or WALLET_CONFIG_JSON
• EVM_RPC_URLS_JSON or RPC_URLS_JSON

🤖 Bankr Integration

For users with Bankr wallets, the plugin supports the Bankr Agent API for transaction execution. This allows agents to execute transactions through Bankr's managed infrastructure.

Option 1: Environment Variable

export BANKR_API_KEY=your-bankr-api-key

Option 2: Config File

Create ~/.openclaw/extensions/amped-defi/config.json:

{
  "walletBackend": "bankr",
  "bankrApiKey": "your-bankr-api-key"
}

⚠️ Important: Your Bankr API key must have "Agent API" access enabled in your Bankr dashboard. A standard bot key won't work.

When configured, the plugin automatically uses Bankr for transaction execution instead of local key signing.

Manual Configuration

If you're not using evm-wallet-skill, set these environment variables:

Required

# Wallet configuration (JSON map of walletId -> {address, privateKey})
export AMPED_OC_WALLETS_JSON='{
  "main": {
    "address": "0xYourWalletAddress",
    "privateKey": "0xYourPrivateKey"
  },
  "trading": {
    "address": "0xAnotherAddress",
    "privateKey": "0xAnotherPrivateKey"
  }
}'

# RPC URLs for all supported chains
export AMPED_OC_RPC_URLS_JSON='{
  "ethereum": "https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY",
  "arbitrum": "https://arb-mainnet.g.alchemy.com/v2/YOUR_KEY",
  "base": "https://base-mainnet.g.alchemy.com/v2/YOUR_KEY",
  "sonic": "https://rpc.soniclabs.com"
}'

Optional

# Operation mode: "execute" (default) or "prepare"
export AMPED_OC_MODE=execute

# Enable dynamic SODAX config (fetches from API)
export AMPED_OC_SODAX_DYNAMIC_CONFIG=true

# Policy limits (JSON)
export AMPED_OC_LIMITS_JSON='{
  "default": {
    "maxSlippageBps": 100,
    "maxSwapInputUsd": 10000,
    "maxBorrowUsd": 50000,
    "allowedChains": ["ethereum", "arbitrum", "base", "sonic"],
    "allowedTokensByChain": {
      "ethereum": ["0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"]
    }
  }
}'

# SODAX API configuration
export SODAX_API_URL=https://canary-api.sodax.com  # or https://api.sodax.com
export SODAX_API_KEY=your-api-key  # if required

🏦 Bankr Integration (Alternative Wallet Backend)

Instead of using local private keys, you can use Bankr as your wallet backend. Bankr manages keys securely and executes transactions on your behalf via their AI Agent API.

Why Bankr?

• No private key exposure - Keys stay with Bankr, never in your config
• Multi-chain support - Base, Ethereum, Polygon, Solana, and more
• Built-in trading features - DCA, limit orders, stop-loss
• Social trading - Send to ENS, Twitter handles, Farcaster

Setup

1. Create a Bankr account at bankr.bot

2. Generate an API key at bankr.bot/api

   • Enable "Agent API" access on the key

3. Configure the plugin:

# Set your Bankr API key
export BANKR_API_KEY=bk_your_api_key_here

# Optionally specify the backend explicitly
export AMPED_OC_WALLET_BACKEND=bankr

Or via config file (~/.openclaw/extensions/amped-defi/config.json):

{
  "walletBackend": "bankr",
  "bankrApiKey": "bk_your_api_key_here",
  "bankrApiUrl": "https://api.bankr.bot"
}

How It Works

When using Bankr backend:

1. Plugin prepares transaction calldata (approvals, swaps, etc.)
2. Submits to Bankr Agent API as an execution request
3. Bankr signs and broadcasts the transaction
4. Plugin receives transaction hash on completion

Important Notes

• Separate wallet: Your Bankr wallet address is different from your personal wallets
• Check your address: Run "What is my wallet address?" in Bankr terminal
• Fund the wallet: Send ETH/gas tokens to your Bankr wallet before trading
• Rate limits: Agent API may have rate limits depending on your plan

Wallet Management

Manage wallets through natural language or tool calls:

Natural Language Examples

"What wallets do I have?"
"Add a wallet called trading with address 0x... and private key 0x..."
"Rename main to savings"
"Make bankr my default wallet"
"Remove the trading wallet"

Multiple Wallet Support

| Source | Default Nickname | Supported Chains | |--------|-----------------|------------------| | evm-wallet-skill | main | All SODAX chains | | Bankr | bankr | Ethereum, Base, Polygon | | Environment | Custom | All SODAX chains |

Using Wallets in Operations

Specify a wallet nickname in any operation:

// Swap using a specific wallet
await agent.call('amped_swap_execute', {
  walletId: 'trading',  // Use the "trading" wallet
  quote: quoteResult,
  maxSlippageBps: 50
});

Or in natural language:

"Swap 100 USDC to ETH using trading"
"Check balance on bankr"

Wallet Config File

Configurations persist to ~/.openclaw/extensions/amped-defi/wallets.json:

{
  "wallets": {
    "trading": {
      "source": "env",
      "address": "0x...",
      "privateKey": "0x..."
    }
  },
  "default": "main"
}

Usage Examples

1. Cross-Chain Position View (Recommended)

Get a complete portfolio overview across all chains:

const positions = await agentTools.call('amped_cross_chain_positions', {
  walletId: 'main'
});

// Response:
{
  summary: {
    totalSupplyUsd: "25000.00",
    totalBorrowUsd: "8000.00",
    netWorthUsd: "17000.00",
    availableBorrowUsd: "12000.00",
    healthFactor: "2.65",
    healthFactorStatus: { status: "healthy", color: "green" },
    liquidationRisk: "none",
    weightedSupplyApy: "4.52%",
    weightedBorrowApy: "3.21%",
    netApy: "2.89%"
  },
  chainBreakdown: [
    { chainId: "ethereum", supplyUsd: "15000.00", borrowUsd: "5000.00", healthFactor: "2.80" },
    { chainId: "arbitrum", supplyUsd: "5000.00", borrowUsd: "2000.00", healthFactor: "2.50" },
    { chainId: "sonic", supplyUsd: "5000.00", borrowUsd: "1000.00", healthFactor: "5.00" }
  ],
  collateralUtilization: {
    totalCollateralUsd: "20000.00",
    usedCollateralUsd: "8000.00",
    utilizationRate: "40.00%"
  },
  riskMetrics: {
    maxLtv: "80.00%",
    currentLtv: "32.00%",
    bufferUntilLiquidation: "53.00%",
    safeMaxBorrowUsd: "13600.00"
  },
  recommendations: [
    "💡 You have $12000.00 in available borrowing power.",
    "🌐 You have positions across 3 chains."
  ]
}

2. Cross-Chain Swap

// Step 1: Get quote
const quote = await agentTools.call('amped_swap_quote', {
  walletId: 'main',
  srcChainId: 'ethereum',
  dstChainId: 'arbitrum',
  srcToken: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // USDC
  dstToken: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831', // USDT
  amount: '1000',
  type: 'exact_input',
  slippageBps: 100
});

// Step 2: Execute
const result = await agentTools.call('amped_swap_execute', {
  walletId: 'main',
  quote: quote,
  maxSlippageBps: 100
});

// Returns: { spokeTxHash, hubTxHash, intentHash, status }

3. Query Intent History

const history = await agentTools.call('amped_user_intents', {
  walletId: 'main',
  status: 'all',     // 'all', 'open', or 'closed'
  limit: 50,
  offset: 0
});

// Returns paginated intent history with event details

Cross-Chain Money Market

The plugin's standout feature is cross-chain money market operations:

Supply USDC on Ethereum → Borrow USDT on Arbitrum

Your collateral stays on the source chain, but you receive borrowed tokens on the destination chain.

Example: Cross-Chain Borrow

// Step 1: Supply on Ethereum
await agentTools.call('amped_mm_supply', {
  walletId: 'main',
  chainId: 'ethereum',
  token: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // USDC
  amount: '50000',
  useAsCollateral: true
});

// Step 2: Borrow to Arbitrum (different chain!)
await agentTools.call('amped_mm_borrow', {
  walletId: 'main',
  chainId: 'ethereum',        // Collateral source
  dstChainId: 'arbitrum',     // Borrowed tokens destination
  token: '0xaf88d065e77c8cC2239327C5EDb3A432268e5831', // USDT
  amount: '20000',
  interestRateMode: 2         // Variable rate
});

// Result: User has 20k USDT on Arbitrum, 50k USDC collateral remains on Ethereum

API Integration

The plugin integrates with the SODAX backend API for enhanced querying:

| Environment | Base URL | |-------------|----------| | Canary (Pre-release) | https://canary-api.sodax.com | | Production | https://api.sodax.com |

Features:

• Paginated Intent History - Query all intents with offset/limit
• Status Filtering - Filter by open/closed status
• Chain/Token Filtering - Filter by source/destination chain or token
• Event History - Full event log for each intent (fills, cancels, etc.)

API Configuration:

export SODAX_API_URL=https://canary-api.sodax.com
export SODAX_API_KEY=your-api-key  # if required

Partner Fee Configuration

To earn partner fees from swaps and bridges, modify the hardcoded values in src/sodax/client.ts:

// src/sodax/client.ts

// HARDCODED PARTNER CONFIGURATION
const PARTNER_ADDRESS: string | undefined = '0xYourPartnerWalletAddress';
const PARTNER_FEE_BPS: number | undefined = 10; // 0.1%

Partner fees are automatically collected from swap and bridge operations and sent to the specified address. These values are hardcoded to ensure consistent fee collection across all plugin instances.

Error Handling

The plugin provides structured error codes for better debugging:

import { ErrorCode, wrapError } from '@amped/openclaw-plugin';

try {
  await agentTools.call('amped_swap_execute', params);
} catch (error) {
  const ampedError = wrapError(error);
  
  console.log(ampedError.code);        // POLICY_SLIPPAGE_EXCEEDED
  console.log(ampedError.message);     // Human-readable message
  console.log(ampedError.remediation); // Suggestion to fix
}

Error Categories:

• Policy Errors - Slippage exceeded, spend limits, chain/token restrictions
• Wallet Errors - Not found, invalid address, missing private key
• Transaction Errors - Failed, timeout, rejected, simulation failed
• SDK Errors - Not initialized, configuration errors

Troubleshooting

Plugin Not Loading in OpenClaw

Issue: Tools not showing up in openclaw tools list

Solutions:

1. Check the allow list — the most common issue. The plugin must be in plugins.allow:

   openclaw config get plugins.allow

   If amped-defi is missing, add it:

   openclaw config set plugins.allow '["amped-defi"]' --json
   openclaw gateway restart

   If you have other plugins allowed, edit ~/.openclaw/openclaw.json and append "amped-defi" to the existing plugins.allow array.

2. Ensure dependencies are installed in the extension directory:

   cd ~/.openclaw/extensions/amped-defi
   npm install

3. Check OpenClaw config has the plugin enabled:

   {
     "plugins": {
       "allow": ["amped-defi"],
       "entries": {
         "amped-defi": { "enabled": true }
       }
     }
   }

4. Check OpenClaw logs for errors:

   tail -100 ~/.openclaw/logs/openclaw.log

"Cannot find module" Errors

This means dependencies weren't installed in the extension directory:

cd ~/.openclaw/extensions/amped-defi
npm install

"plugin not found" After Uninstall

Edit ~/.openclaw/openclaw.json and remove the stale entry:

# Remove the amped-defi entry from plugins.entries
nano ~/.openclaw/openclaw.json

Wallet Not Found Errors

Ensure you have either:

• EVM_WALLETS_JSON set (if using evm-wallet-skill)
• AMPED_OC_WALLETS_JSON set (plugin-specific)
• Or configure via OpenClaw plugin settings

RPC URL Not Configured

Ensure you have either:

• EVM_RPC_URLS_JSON set (if using evm-wallet-skill)
• AMPED_OC_RPC_URLS_JSON set (plugin-specific)
• Or configure via OpenClaw plugin settings

Security Model

• Key Segregation - Each agent workspace has distinct wallet configurations
• Spoke Provider Caching - Cached per walletId, never shared across agents
• Policy Enforcement - Spend limits, slippage caps, chain/token allowlists
• Simulation - Transactions simulated before execution by default
• No Key Logging - Private keys never logged or exposed

Supported Chains
