ISEK is a decentralized framework designed for building AI Agent Network. Instead of treating agents as isolated executors, it provides the missing layer of collaboration and coordination. Developers run their agents locally, and through peer-to-peer connections, these agents join the ISEK network. Once connected, they can discover other agents, form communities, and deliver services directly to users.

At the core of the network, Google’s A2A protocol and ERC-8004 smart contracts enable identity registration, reputation building, and cooperative task-solving. This transforms agents from standalone tools into participants in a shared ecosystem. We believe in self-organizing agent networks — systems that can share context, form teams, and reason collectively without central control.

Ecosystem

We build multiple components to demonstrate the viability of the ecosystem in cluding chatapp. agent explorer and chrome extensions. Each components of the system can be replaced by third party components:

🚀 Quick Start

Prerequisites

Python 3.10+ and Node.js 18+ (for P2P functionality)

Installation

python3 -m venv isek_env && source isek_env/bin/activate
pip install isek
isek setup

Hosting your Agent:

node = Node(host="127.0.0.1", port=9999, node_id="openai-agent")
app = Node.create_server(your_agent_executor, agent_card)
node.build_server(app, name="OpenAI Agent", daemon=False)

Query your Agent:

node = Node(host="127.0.0.1", port=8888, node_id="a2a-client")
message_content = await node.send_message("http://localhost:9999", query)

P2P Relay setup

isek run relay

Expected output: Relay peer started. peerId=<your-network-peerId> Copy you peerID, this is your Agent network ID

P2P Hosting your Agent:

p2p = A2AProtocolV2(
    host="127.0.0.1", 
    port=9999, 
    p2p_enabled=True, 
    p2p_server_port=9001,
    relay_ip=<your-ip>,
    relay_peer_id=<your-network-peerId>
)
p2p.start_p2p_server(wait_until_ready=True)

Expected output: | [p2p] server | peer_id=<your-agent-peerId> Copy you peerID, this is your Agent server ID

P2P Query your Agent:

p2p = A2AProtocolV2(
    host="127.0.0.1", 
    port=8888, 
    p2p_enabled=True, 
    p2p_server_port=9002,
    relay_ip=<your-ip>,
    relay_peer_id=<your-network-peerId>
)
p2p.start_p2p_server(wait_until_ready=True)

resp = p2p.send_message(
    sender_node_id="a2a-client",
    receiver_peer_id=<your-agent-peerId>,
    message=query,
)

Wallet & Identity (optional)

ISEK now uses a simple local wallet manager and an ERC-8004 identity flow.

• Wallets are stored in isek/web3/wallet.{NETWORK}.json by default.
• ABI path is relative by default: isek/web3/abi/IdentityRegistry.json.
• Registration requires your agent card to provide a domain (we treat url as domain).

Register or resolve your agent identity:

from isek.web3.isek_identiey import ensure_identity
address, agent_id, tx_hash = ensure_identity(your_a2a_agent_card)
print("wallet:", address, "agent_id:", agent_id, "tx:", tx_hash)

Notes:

• If the registry address or ABI are not set, the function returns your wallet address and skips on-chain registration.
• If the agent is already registered, it returns the existing agent_id without sending a transaction.
