🤖 Web3 Agent Kit

Build autonomous AI agents that interact with blockchains — in minutes, not months.

[!WARNING] Web3 Agent Kit is beta software. Module readiness ranges from stable to experimental, and availability does not imply unattended mainnet safety. Review the maturity policy and risk disclosure before using real funds.

Feature readiness is tracked in the capability matrix.

⚡ Quick Install

pip install web3-agent-kit

Verify installation:

wak info        # Show version, modules, chains
wak doctor      # Check dependencies
wak examples    # List 19 example scripts

Run your first swap:

from web3_agent_kit import Agent, Wallet, Chain

wallet = Wallet.from_key("0x...")
agent = Agent(wallet=wallet, chains=[Chain.BASE])
# or: agent = Agent(private_key="0x...", chains=[Chain.BASE])

result = agent.run("check my balances")  # agent.execute(...) also works
print(result)

🤔 Why Web3 Agent Kit?

Building AI agents that interact with blockchains is hard. You need to juggle RPC providers, wallet management, transaction signing, gas estimation, DeFi protocol ABIs, LLM integration, and safety rails — all before writing a single line of business logic.

Web3 Agent Kit handles all of that for you.

📊 Comparison vs Alternatives

🎯 Quick Start

A small, policy-controlled starting point.

pip install web3-agent-kit
export PRIVATE_KEY="0x..."
export ANTHROPIC_API_KEY="sk-ant-..."

from web3_agent_kit import Agent, Wallet, Chain, ChainManager
from web3_agent_kit.defi import Uniswap

chain = ChainManager(chains=[Chain.BASE])
wallet = Wallet.from_env("PRIVATE_KEY", chain_manager=chain)

agent = Agent(wallet=wallet, chains=[Chain.BASE], tools=[Uniswap(chain_manager=chain)])
result = agent.run("Swap 0.1 ETH to USDC on Base")

That's it. Install the package, configure the provider and wallet, then run a policy-controlled agent.

🔐 Governed by default: every Agent ships with a conservative SpendGovernor out of the box (max 0.05 ETH/tx, 0.5 ETH/day, 1.0 ETH/session) — the swap above would be blocked unless you raise the limits or pass your own governor:

from web3_agent_kit.utils import SpendGovernor, SpendLimits

config = AgentConfig(
    wallet=wallet,
    chains=[Chain.BASE],
    tools=[Uniswap(chain_manager=chain)],
    governor=SpendGovernor(SpendLimits(max_per_tx=1.0, daily_limit=5.0, session_limit=10.0)),
)
agent = Agent(config=config)

To run with no spending caps (not recommended), set config.governor = None after construction, only if you fully understand the risk.

CLI? wak agent --goal "Swap 0.1 ETH to USDC" --chain base

More examples: wak examples or browse examples/ — 19 working scripts (DCA bot, sniper, airdrop farmer, multi-wallet, yield optimizer, bridge agent, portfolio tracker, and more).

💡 Tip: Start with dry_run=True on testnet to validate before going live.

🌐 REST API

HTTP API for supported modules — use it from any language (JavaScript, curl, etc):

# WEB3_API_KEY is required — the server refuses to start without it
export WEB3_API_KEY=your-secret

# Start the API server (binds to 127.0.0.1 by default)
python -m web3_agent_kit.api

# Every request must include the key
curl -H "X-API-Key: ***" http://127.0.0.1:8000/wallet/info

⚠️ Breaking change (v1.14.0+): WEB3_API_KEY is now mandatory — the server raises an error at startup and refuses to run if it's unset. The default bind host also changed from 0.0.0.0 to 127.0.0.1. To expose the API on your network, set API_HOST=0.0.0.0 explicitly (a startup warning will remind you that this exposes wallet-signing endpoints). CORS origins must be set explicitly via CORS_ALLOWED_ORIGINS (comma-separated) — no origins are allowed by default.

Endpoints:

💡 Full list of endpoints available in Swagger UI when the server is running.

Example:

# Get gas estimate
curl http://localhost:8000/gas/estimate?chain=ethereum

# Get swap quote
curl "http://localhost:8000/swap/quote?token_in=ETH&token_out=USDC&amount_in=1.0"

# Scan approvals
curl http://localhost:8000/approval/scan?chain=ethereum

🎯 Showcase

Telegram Bot

A full-featured Telegram bot built with web3-agent-kit:

cd showcase/telegram-bot
pip install -r requirements.txt
python bot.py

Features: balance check, token swap, portfolio tracking, token sniper, cross-chain bridge.

📦 Examples

🧠 LLM Integration

Multi-provider cascade with automatic fallback:

from web3_agent_kit.agent import LLM, LLMConfig

# Use any LLM provider with automatic fallback
llm = LLM(LLMConfig(
    providers=["anthropic", "openai", "groq", "deepseek"],
    model="claude-3-5-sonnet-20241022",
))

# Natural language → structured action
action = llm.parse("Swap 0.1 ETH to USDC on Base")
# → {"tool": "uniswap", "action": "swap", "params": {...}}

🔒 Security Module

Analyze tokens before interacting:

from web3_agent_kit.security import TokenAnalyzer, SecurityConfig

analyzer = TokenAnalyzer(SecurityConfig(chain="base"))

# Quick check
result = analyzer.quick_check("0x...")
print(f"Is Honeypot: {result['is_honeypot']}")

# Full analysis
report = analyzer.analyze_token("0x...")
print(f"Safety Score: {report.safety_score}/100")
print(f"Risk Level: {report.risk_level.value}")

if report.is_honeypot:
    print("🚨 HONEYPOT DETECTED!")
elif report.safety_score < 50:
    print("⚠️ HIGH RISK TOKEN")
else:
    print("✓ Safe to trade")

🪂 Airdrop Automation

Automate airdrop farming across multiple platforms:

from web3_agent_kit.airdrop import (
    CampaignDiscovery,
    OnChainAirdropFarmer,
    OnChainConfig,
    AirdropScheduler,
    PointsDashboard,
    ReferralManager,
    FaucetClaimer,
)

# Discover new campaigns
discovery = CampaignDiscovery()
campaigns = discovery.discover_all()

# On-chain farming (dry run)
farmer = OnChainAirdropFarmer(OnChainConfig(chain="base", dry_run=True))
farmer.farm_plan("base_activity")

# Schedule daily tasks
scheduler = AirdropScheduler()
scheduler.add_daily("galxe_checkin", "09:00", galxe_checkin_fn)

# Track points
dashboard = PointsDashboard(DashboardConfig(wallet="0x..."))
dashboard.sync_all()

# Generate referrals
manager = ReferralManager()
manager.generate_links(count=10)

# Claim testnet tokens
claimer = FaucetClaimer()
claimer.claim_all(wallet="0x...")

🔄 Restaking

Optimize yields across restaking protocols:

from web3_agent_kit.plugins.restaking import (
    EigenLayer,
    EigenLayerConfig,
    RestakingOptimizer,
    RestakingMonitor,
    BabylonBtcRestaking,
    SolanaRestaking,
)

# EigenLayer restaking
el = EigenLayer(EigenLayerConfig(chain="ethereum"))
result = el.restake("stETH", 10.0)
print(f"Restaked: {result.tx_hash}")

# Find best restaking yield
optimizer = RestakingOptimizer()
best = optimizer.find_best_opportunity(min_apy=3.0)
print(f"Best: {best.protocol} — {best.apy}% APY")

# Monitor positions
monitor = RestakingMonitor()
snapshot = monitor.get_portfolio_snapshot()
print(f"Total staked: ${snapshot.total_value_usd:,.2f}")
print(f"Slashing risk: {snapshot.total_risk_score}")
