xmtp 0.1.3

Unofficial Python SDK for the XMTP network.

xmtp

Unofficial Python client SDKs for the XMTP network.

Primary goal: feature parity with xmtp-js.

This is a community project that mirrors the structure and interfaces of the official xmtp-js SDK, adapted for Python.

What's inside?

SDKs

• python-sdk: XMTP client SDK for Python
• agent-sdk: XMTP agent SDK for Python (event-driven, middleware-powered)

Content types

• content-type-primitives: Primitives for building custom XMTP content types
• content-type-group-updated: Content type for group update messages
• content-type-reaction: Content type for reactions to messages
• content-type-read-receipt: Content type for read receipts
• content-type-remote-attachment: Content type for file attachments stored off-network
• content-type-reply: Content type for direct replies to messages
• content-type-text: Content type for plain text messages
• content-type-transaction-reference: Content type for on-chain transaction references
• content-type-markdown: Content type for markdown-formatted messages
• content-type-wallet-send-calls: Content type for wallet transaction requests

Requirements

• Python 3.10+
• libxmtp bindings >= 1.7.0-r3

Installation

pip install xmtp

This installs the client SDK, agent SDK, and built-in content types in one package.

Install from GitHub main

pip install "xmtp @ git+https://github.com/pierce403/xmtp-py.git@main"

From source (dev)

Clone the repo and install into a virtualenv. Install the bindings first so the local editable package can resolve them:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -U pip

pip install -e bindings/python
pip install -e ".[dev]"

Quick start

Python SDK

from xmtp import Client
from xmtp.signers import create_signer
from xmtp.types import ClientOptions

# Create a signer from a private key
signer = create_signer(private_key)

# Create the client
client = await Client.create(signer, ClientOptions(env='dev'))

# Create a conversation
dm = await client.conversations.new_dm("0x...")
await dm.send("Hello from Python!")

# Stream messages
async for message in client.conversations.stream_all_messages():
    print(f"Received: {message.content}")

Agent SDK

from xmtp_agent import Agent
from xmtp_agent.user import create_user, create_signer
from xmtp.types import ClientOptions

# Create a user and signer
user = create_user()
signer = create_signer(user)

# Create the agent
agent = await Agent.create(signer, ClientOptions(env='dev', db_path=None))

# Handle text messages
@agent.on("text")
async def handle_text(ctx):
    await ctx.send_text("Hello from my XMTP Agent! 👋")

# Start the agent
await agent.start()

Key management tips

• create_user() generates an in-memory key; persist the private key yourself if you want a stable inbox across restarts.
• Prefer XMTP_WALLET_KEY and XMTP_DB_ENCRYPTION_KEY in environment variables or a secrets manager; never commit them to git.
• Use a stable db_path and keep the database directory between runs. Losing it creates a new installation and can hit installation limits.
• For production, wrap a hardware wallet or KMS signer by implementing the Signer protocol instead of storing raw keys.

Configuration & troubleshooting

Endpoint overrides via env:

• XMTP_ENV, XMTP_API_URL, XMTP_HISTORY_SYNC_URL, XMTP_GATEWAY_HOST
• XMTP_DISABLE_HISTORY_SYNC=1 to force identity calls through the primary API

Common issues:

• Missing libxmtpv3.so: install will build it automatically, but you need Rust (cargo) and git. See bindings/python/README.md for overrides. If no prebuilt wheels are available, pip install xmtp will fall back to a source build.
• History sync gRPC errors: set XMTP_DISABLE_HISTORY_SYNC=1, or set XMTP_HISTORY_SYNC_URL to a working gRPC endpoint. You can also pass history_sync_url='' in ClientOptions.
• Gateway host errors: gateway_host is an advanced setting; only set it when you have a gateway that supports XMTP gRPC.

LibXMTP bindings

This SDK uses libxmtp Python bindings for core XMTP functionality including cryptography, networking, and protocol implementation.

Minimum version: 1.7.0-r3
