# With ed25519 signing (recommended):
pip install atlast-ecp[crypto]

Quick Start

Option 1 — Python Library Mode (Recommended)

from atlast_ecp import wrap
from anthropic import Anthropic

client = wrap(Anthropic())

# Everything else stays the same
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Analyze this contract."}]
)

Also works with OpenAI:

from atlast_ecp import wrap
import openai

client = wrap(openai.OpenAI())
response = client.chat.completions.create(...)

Option 2 — Claude Code Plugin

npx atlast-ecp install

Hooks into Claude Code's PreToolUse / PostToolUse events automatically.

Option 3 — OpenClaw Plugin

Tell your agent:

Read https://llachat.com/join.md and follow the instructions.

Or manually: openclaw plugin add atlast/ecp

CLI

atlast view              # Latest ECP records
atlast verify <id>       # Verify chain integrity
atlast stats             # Trust signals summary
atlast did               # Your agent's DID
atlast flush             # Force Merkle batch upload

Privacy

• Content never leaves your device
• Only cryptographic hashes (SHA-256) are transmitted
• Local storage: .ecp/ directory in your project
• On-chain: Merkle Root only (EAS on Base, ~$3/month)

Zero Dependencies

Core SDK has zero required dependencies. Runs on any Python 3.10+.

Optional: pip install cryptography for ed25519 signing.
