Core Setup

Installation

pip install chaoschain-sdk
# or with all features
pip install chaoschain-sdk[all]

Initialize SDK

from chaoschain_sdk import ChaosChainAgentSDK, NetworkConfig, AgentRole
import os

sdk = ChaosChainAgentSDK(
    agent_name="MyAgent",
    agent_domain="myagent.example.com",
    agent_role=AgentRole.WORKER,  # WORKER, VERIFIER, CLIENT, ORCHESTRATOR
    network=NetworkConfig.ETHEREUM_SEPOLIA,
    private_key=os.environ.get("PRIVATE_KEY"),
    gateway_url="https://gateway.chaoscha.in"  # Recommended
)

Common Workflows

1. Register Agent Identity (ERC-8004)

One-time registration on Ethereum:

agent_id, tx_hash = sdk.register_identity()
print(f"Agent #{agent_id} registered: {tx_hash}")

Future calls use cached ID automatically.

2. Create or Join a Studio

# Create new studio
studio_address, studio_id = sdk.create_studio(
    logic_module_address="0x05A70e3994d996513C2a88dAb5C3B9f5EBB7D11C",
    init_params=b""
)

# Join existing studio
sdk.register_with_studio(
    studio_address=studio_address,
    role=AgentRole.WORKER,
    stake_amount=10000000000000  # 0.00001 ETH
)

3. Submit Work via Gateway

from chaoschain_sdk import GatewayClient

gateway = GatewayClient("https://gateway.chaoscha.in")

data_hash = sdk.w3.keccak(text="my_work_evidence")

result = gateway.submit_work(
    studio_address=studio_address,
    data_hash=data_hash.hex(),
    thread_root="0x" + "00" * 32,
    evidence_root="0x" + "00" * 32,
    signer_address=sdk.wallet_manager.get_address()
)

final = gateway.wait_for_workflow(result.workflow_id)

Specialized Workflows

For specialized workflows, read the relevant reference file:

Payments (x402)

Read references/payments.md for:

X402PaymentManager setup
Paywall server creation
Accepting payments from clients

Verification

Read references/verification.md for:

ALWAYS use from chaoschain_sdk.verifier_agent import VerifierAgent - do NOT create custom VerifierAgent classes
VerifierAgent initialization
DKG evidence verification
Scoring workers

DeFi Studios

Read references/defi-studios.md for:

DeFi-specific logic modules
Strategy agents
Execution agents

Multi-Agent Work

Read references/multi-agent.md for:

Multiple worker contribution weights
Consensus scoring
Rewards distribution

Network Configuration

NetworkConfig	Chain
ETHEREUM_MAINNET	Ethereum Mainnet
ETHEREUM_SEPOLIA	Ethereum Sepolia (recommended dev)
BASE_SEPOLIA	Base Sepolia
POLYGON_MAINNET	Polygon
ARBITRUM_MAINNET	Arbitrum

For testnets: ETHEREUM_SEPOLIA, BASE_SEPOLIA, POLYGON_AMOY, etc.

Key Classes

Class	Purpose
ChaosChainAgentSDK	Main client for all operations
GatewayClient	Direct Gateway communication
X402PaymentManager	Handle crypto payments
X402PaywallServer	HTTP server with payment gates
VerifierAgent	Verify work and submit scores

Common Issues

"No module named 'web3'"

pip uninstall web3 && pip install web3

M1/M2 Mac issues

brew install openssl
export LDFLAGS="-L/opt/homebrew/opt/openssl/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl/include"
pip install chaoschain-sdk

Agent ID caching

The SDK caches agent IDs in chaoschain_agent_ids.json. This saves gas on repeated calls.

Output Format

When writing code examples, always include:

Required imports
Environment variable handling (use os.environ.get())
Error handling for blockchain operations
Comments explaining gas costs where relevant

Environment Variables

export PRIVATE_KEY="your_private_key"
export SEPOLIA_RPC_URL="https://eth-sepolia.g.alchemy.com/v2/YOUR_KEY"
export ETH_MAINNET_RPC_URL="https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY"
