xmtp 0.1.6

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

Agent SDK (recommended)

import asyncio
import xmtp

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

recipient = "deanpierce.eth"


async def main() -> None:
    # Create a user and signer
    user = create_user()
    signer = create_signer(user)

    # Create the agent
    agent = await Agent.create(
        signer,
        ClientOptions(
            env="production",
            disable_history_sync=True,
            db_path=None,
        ),
    )

    # Resolve the recipient and send a message
    resolver = create_name_resolver()
    address = await resolver(recipient)
    if address is None:
        raise ValueError(f'Could not resolve address for "{recipient}"')

    dm = await agent.client.conversations.new_dm(address)
    await dm.send(f"Hello from xmtp-py {xmtp.__version__}")


if __name__ == "__main__":
    asyncio.run(main())

Python SDK (client)

import asyncio
import xmtp

from xmtp import Client
from xmtp.signers import create_signer
from xmtp.types import ClientOptions
from xmtp_agent.name_resolver import create_name_resolver

recipient = "deanpierce.eth"


async def main() -> None:
    signer = create_signer(private_key)
    client = await Client.create(
        signer,
        ClientOptions(
            env="production",
            disable_history_sync=True,
        ),
    )

    resolver = create_name_resolver()
    address = await resolver(recipient)
    if address is None:
        raise ValueError(f'Could not resolve address for "{recipient}"')

    dm = await client.conversations.new_dm(address)
    await dm.send(f"Hello from xmtp-py {xmtp.__version__}")


if __name__ == "__main__":
    asyncio.run(main())

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

History sync is disabled by default. To enable it, pass disable_history_sync=False (and optionally history_sync_url) in ClientOptions, or set XMTP_HISTORY_SYNC_URL.

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
• XMTP_RUST_LOG to override Rust logging (defaults to off)

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: leave history sync disabled, or set XMTP_DISABLE_HISTORY_SYNC=1. To re-enable, pass disable_history_sync=False (and optionally 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.
• Noisy Rust logs: set XMTP_RUST_LOG=error or pass rust_log="error" in ClientOptions.

LibXMTP bindings

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

Minimum version: 1.7.0-r3
