MUTX

Your keys. Your rules. Agents link up.

Agents link up on-chain. You stay in control.
Scoped authority, manual approvals, and Link — the open agent interface.
No private keys leave your machine.

See it in action

Agents talk. MUTX decides.

Real prompts, real tools. Every action flows through your approval — or an SLK you scoped.

Agent prompt

"Check my SOL balance and list all tokens in the Main wallet."

wallet_balance wallet_token_list

2.34 SOL • USDC 150.00 • BONK 1,200,000

Agent prompt

"Send 5 USDC to alice.sol from the Trading wallet."

wallet_token_send

Awaiting operator approval in MUTX… Approved. Tx confirmed.

Agent prompt

"Request a 1-hour SLK for the DCA wallet, max 10 USDC per trade."

request_slk

SLK issued • Expires in 60m • Budget: 10 USDC/tx

Agent prompt

"Swap 1 SOL for USDC on Jupiter using the Main wallet."

wallet_swap

Quote: 1 SOL → 148.52 USDC • Slippage 0.5% • Confirmed.

Agent prompt

"Connect to Raydium and pair with the Trading wallet via WalletConnect."

wallet_connect

Session proposal received • Approved in MUTX • Connected.

What MUTX does

The authority layer between agents and wallets.

Approve what matters. Automate what doesn't.
Every signing path is short-lived, scoped, and revocable.

Security Model

Short Lived Keys replace broad key sharing with explicit scope, duration, and device controls.

Operator Flow

Human-in-the-loop approval stays in front of high-risk actions while routine automation keeps moving.

Runtime Fit

Run MUTX locally, connect agents through Link, and keep Solana wallet portability through BIP44.

The problem

Agents need to sign. You need to decide who signs, when, and for how long.

Private keys should never leave your machine.
MUTX issues bounded authority instead.

Short Lived Keys

Time-bound, scoped, revocable authority.

Instead of sharing a private key, issue an SLK: a permission envelope with a budget, an expiry, and an allowed action set.

  • Set duration, budget cap, and permitted operations.
  • Revoke instantly from MUTX at any time.
  • Wallets stay portable across Phantom and Backpack (BIP44).
Deployment Modes

Use it the way your team already ships.

Terminal

For operators who want direct terminal control and fast approval loops.

Link

For model-connected workflows that need wallet actions through MCP or CLI.

Docker

For repeatable local and team environments with a clean startup path.

Static Binaries

For direct installs on Linux and macOS without extra runtime dependencies.

How it works

Four steps from install to production.

Create or import a wallet. Scope authority.
Connect an agent. Keep full visibility from the terminal.

01

Create or import a wallet.

BIP44-standard. Works with Phantom, Backpack, and any compatible path. Your keys never leave the device.

02

Issue a Short Lived Key.

Define budget, duration, and allowed actions. The agent gets scoped authority, not your seed phrase.

03

Connect via Link or approve in MUTX.

Models call wallet tools through Link. Anything outside the SLK scope lands in your approval queue.

04

Revoke, adjust, or renew in seconds.

Change what an agent can do without restarting the session. Full transaction history stays in MUTX.

Designed For

Autonomous trading, research agents, internal operator tooling, and guarded execution loops.

Keeps

Human approval on the path for sensitive actions instead of pretending full autonomy is safe.

Avoids

Long-lived, overprivileged wallet access hidden behind a single "connect agent" button.

Use cases

One tool, every scale.

Same security model at every scale. Pick the surface that fits your workflow.

Solo Operator

Terminal-first wallet control.

Manage wallets, approve transactions, and monitor agents from a single MUTX session. No browser needed.

Agent Builder

Give models wallet tools, not wallet keys.

Connect any MCP-compatible model. SLKs scope what the agent can do. You approve the rest.

Team Deployment

Reproducible setup via Docker or binaries.

Same runtime, same controls, every machine. Health checks and structured logs included.

Pricing

Start free. Scale when you need to.

Full MCP support and human-in-the-loop on every tier.
Buy directly from MUTX in USDC — no external checkout, no auto-renewal, pay only when you use it.

Talk to MUTX

Get started

Install in under a minute.

Docker or static binaries. Linux and macOS.
Mix and match — run MUTX as a binary and Link in Docker, or the other way around.

1

Pick your format

Docker for isolation and reproducibility. Binaries for zero-dependency speed.

2

Run both components

Start MUTX first, then Link. They communicate over a local Unix socket.

3

Verify the build

Every release includes SHA-256 checksums. Verify before you run.

Official OCI images on GitHub Container Registry.

Both components communicate over a shared Unix socket at /tmp/mutx.

You can mix Docker and binary installs freely.

ghcr.io/mutx-net/mutx

MUTX 
docker run --rm -it \
  -v ./mutx/config:/home/mutx/.config/mutx \
  -v ./mutx/data:/home/mutx/.local/share/mutx \
  -v /tmp/mutx:/tmp/mutx \
  ghcr.io/mutx-net/mutx:latest

ghcr.io/mutx-net/mutx-link

Link

Start MUTX first, then Link. They only need to share /tmp/mutx — one can be Docker, the other a binary.

Static binaries with zero runtime dependencies. Platform is auto-detected.

Download, chmod, run, and verify with the matching SHA-256 file.

You can mix binaries and Docker freely — e.g., run MUTX natively and Link in Docker.
