🤔 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.

Pain Point	Without Web3 Agent Kit	With Web3 Agent Kit
Setup	Days of boilerplate	pip install → 5 lines of code
Multi-chain	Write adapters per chain	Built-in for 7+ chains
LLM Integration	Manual prompt engineering	Natural language goals, auto-parsed
Safety	Build your own guardrails	Spend limits, kill switch, operator confirmation
DeFi	Read docs, write ABIs	Drop-in Uniswap, Aave, bridges
Yield	Manual research, claim, compound	Auto-compound, cross-protocol APY comparison
DCA	Manual recurring buys	Automated DCA with intervals, limits, callbacks
Gas	Guess gas prices	Smart estimation, timing, batching
Security	Manual approval checks	Auto-scan & revoke risky approvals
Alerts	Manual whale tracking	Auto-monitor wallets, instant alerts
Multi-wallet	Manage keys manually	Batch ops, consolidated portfolio, wallet groups
Airdrops	Manual quest hunting	Auto-track campaigns, multi-wallet farming, Sybil-safe
Extensibility	Hard-coded logic	Plugin system — community can extend anything
Error Handling	Manual retry logic	Auto-fallback across LLM providers & RPCs

🎯 Quick Start

1. Install

pip install web3-agent-kit

2. Set Environment Variables

# Required: Wallet private key
export PRIVATE_KEY="0x..."

# Required: At least one LLM provider key
export OPENAI_API_KEY="sk-..."        # OpenAI
export ANTHROPIC_API_KEY="sk-ant-..."  # Anthropic (best reasoning)
export GROQ_API_KEY="gsk_..."          # Groq (fastest)
export DEEPSEEK_API_KEY="sk-..."       # DeepSeek (cheapest)

# Optional: Custom RPC endpoints (public defaults are provided)
export ETH_RPC="https://..."
export BASE_RPC="https://..."

3. Write Your First Agent

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

# Setup
chain_manager = ChainManager(chains=[Chain.BASE])
wallet = Wallet.from_env("PRIVATE_KEY", chain_manager=chain_manager)
uniswap = Uniswap(chain_manager=chain_manager)

# Create agent with LLM reasoning
agent = Agent(
    wallet=wallet,
    chains=[Chain.BASE],
    tools=[uniswap],
)

# Natural language swap — that's it!
result = agent.run("Swap 0.1 ETH to USDC on Base")
print(result)

4. Run It

python my_agent.py

💡 Tip: Start with a small amount on a testnet or use dry_run=True mode to validate behavior before going live.

⚡ Benchmarks

📝 Benchmarks will be published after v1.0 release. Numbers below are preliminary estimates on standard hardware.

Metric	Value	Notes
Swap execution (incl. LLM)	~3–8s	Depends on LLM provider
Swap execution (no LLM)	~1–3s	Direct RPC interaction
Portfolio fetch (7 chains)	~2–4s	Parallel RPC calls
Sniper block scan (100 blocks)	~5–10s	Per chain
Bridge route discovery	~1–2s	Aggregator API latency

Benchmarks run on: Python 3.11, 4-core CPU, SSD, public RPC endpoints.

🔐 Safety

Web3 Agent Kit includes built-in safety features:

from web3_agent_kit.safety import SpendGovernor, SpendLimits

governor = SpendGovernor(
    limits=SpendLimits(
        max_per_tx=0.1,      # max 0.1 ETH per transaction
        daily_limit=1.0,     # max 1 ETH per day
    ),
    require_confirm=True,    # operator must confirm
)

# Kill switch for emergencies
governor.kill()   # blocks all transactions
governor.unkill() # resume
