modbender Einstein — Blockchain Analytics via x402
Einstein provides 27 blockchain analytics services accessible via x402 micropayments (USDC on Base). Each query costs $0.25–$1.15 depending on complexity.
Quick Start
# 1. Install dependencies (manual step — the setup wizard will NOT run npm for you)
cd packages/project-einstein/openclaw-skill/einstein && npm install
# 2. Set your private key via environment variable (recommended)
export EINSTEIN_X402_PRIVATE_KEY=0x_your_private_key_here
# 3. Or run the interactive setup wizard
node scripts/einstein-setup.mjs
# 4. List all services (free)
node scripts/einstein.mjs services
# 5. Run a query (will prompt for payment confirmation)
node scripts/einstein.mjs top-movers --chain base --limit 10
Requirements:
- Node.js 18+
- Dependencies installed via
npm install(not auto-installed) - A dedicated wallet private key with USDC on Base network (do NOT use your main wallet)
- Set
EINSTEIN_X402_PRIVATE_KEYenvironment variable (preferred) or run setup with--save-config

How Payment Works
Einstein uses the x402 protocol — an HTTP-native micropayment standard. Payment is automatic:
- Your request hits Einstein's endpoint
- Server responds with HTTP 402 + payment challenge
- The skill signs a USDC TransferWithAuthorization (EIP-3009) using your private key
- Request is re-sent with the payment signature
- Coinbase CDP facilitator settles the USDC transfer on Base
- You receive the analytics data
No accounts, no API keys, no subscriptions. Just USDC on Base and a private key.

Security Best Practices
Use a dedicated wallet. Create a separate wallet funded with a small amount of USDC for this skill. Do NOT use your primary wallet or any wallet holding significant funds.
Prefer environment variables over config.json. Environment variables (EINSTEIN_X402_PRIVATE_KEY) are not persisted to disk and are harder to accidentally commit to git. If you must use config.json (--save-config), restrict file permissions:
chmod 600 config.json
What gets signed. Each paid query signs an EIP-3009 TransferWithAuthorization message that authorizes a USDC transfer of the exact query price (shown before confirmation) from your wallet to the Einstein service address. The signature is single-use (unique nonce) and time-limited. No blanket approvals are granted.
Payment confirmation. By default, the CLI prompts before every paid query showing the exact cost. To skip the prompt for scripted/automated use, pass --yes / -y per-command or set EINSTEIN_AUTO_CONFIRM=true globally.
No auto-installed packages. The setup wizard does NOT run npm install automatically. You must install dependencies yourself so you can audit what is being installed.
No home directory scanning. Configuration is loaded only from environment variables and the skill-local config.json. No paths outside the skill directory are read.
Troubleshooting
"No private key configured"
Set EINSTEIN_X402_PRIVATE_KEY environment variable or run node scripts/einstein-setup.mjs --save-config.
"Payment rejected" / "Insufficient balance" Your wallet needs USDC on Base. Bridge via https://bridge.base.org. Use a dedicated wallet with a small balance.
"Cannot reach emc2ai.io" Check internet connection. The service may have temporary downtime.
"Unknown service"
Run node scripts/einstein.mjs services to see all available commands.
"Dependencies not installed"
Run npm install in the skill directory: cd packages/project-einstein/openclaw-skill/einstein && npm install
