Overview

AI-generated overview

Local MCP server for ZeroDust that lets an AI assistant sweep a wallet's native gas balance to exactly zero on EVM chains.

What you can do
  • Sweep native gas tokens from a wallet to exactly zero wei on supported EVM chains
  • Send the swept balance to another address on the same chain or bridge it to another chain
  • Quote sweeps across sponsored, MetaMask-permission and direct chains, with fees and destination options
  • Run locally over stdio against the ZeroDust public API using your own API key
When to use it
Useful when you want an assistant to help empty a wallet's remaining native gas on an EVM chain, either to a same-chain address or bridged elsewhere, and you are comfortable signing sweep intents. The vendor notes the agent packages are paused and deprecated on npm, so check current availability before relying on it.
Requirements
Runs as a local process over stdio, installed from the npm package @zerodust/mcp-server, so a Node.js runtime is needed. Requires a ZeroDust API key supplied as the ZERODUST_API_KEY environment variable; ZERODUST_API_URL can override the default API endpoint. Network access to the ZeroDust API and the relevant chains is required.
Before you install
The server moves real funds: sweeps transfer a wallet's entire native balance and are irreversible. Fees apply (1% of swept value, at least $0.05 and at most $0.50; 5% for balances under $1) plus gas and bridge fees. Sweeps involve EIP-7702 delegations and signed intents, and the README states the contracts are not externally audited. The API key is a secret; the agent packages are described as paused and deprecated.

Installation

In SourceWeft

  1. Open Zerodust in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

README

ZeroDust

Empty a wallet's native gas balance on an EVM chain to exactly 0.

A normal transfer cannot send a whole native balance, because paying for the transfer uses the token being sent. ZeroDust sends all of it, to any address on the same chain or bridged to another chain, and the wallet ends at exactly 0 wei. Live at zerodust.xyz, with an API at https://api.zerodust.xyz and developer docs at zerodust.xyz/docs.

This repository holds the contracts, the TypeScript SDK and the agent packages.

How it works

  • Sponsored chains (EIP-7702): the wallet signs a SweepIntent and two EIP-7702 authorizations (one delegating to the ZeroDust contract, one removing it afterwards). A ZeroDust sponsor executes the sweep and pays the gas, reimbursed from the swept balance. The contract runs as the wallet and reverts unless the balance ends at exactly 0.
  • MetaMask without a key: MetaMask's Advanced Permissions (ERC-7715) grant ZeroDustPermissionRouter a one-time allowance per chain; one EIP-712 signature covers every chain. The router redeems it, requires exactly 0, and settles like the contract. 16 chains.
  • Direct chains (no EIP-7702): the wallet sends its own legacy transactions, sized to the wei by the API's planner (22 chains). On OP-stack chains with an L1 data fee it goes through ZeroDustGuard; on ZK-stack chains a ZeroDust paymaster pays the gas.
  • What arrives: the destination's native gas, carried by Relay, Across (ETH to ETH), Stargate or Gas.zip, whichever delivers the most. A few chains whose coin no gas bridge carries deliver it as a token instead (Mitosis, Endurance, Intuition, Telos, 0G), said plainly in the quote. On request a sweep can also go into the chain's own bridge to Ethereum (to BNB Chain for opBNB), which the recipient proves and claims there later; Gravity's G and Fraxtal's FRAX arrive on Ethereum as the G and FXS tokens.

For AI agents (paused)

The agent packages (@zerodust/mcp-server, @zerodust/ai-sdk, @zerodust/langchain) are paused and deprecated on npm, and the hosted MCP endpoint and agent key signup are switched off. The local MCP server and the SDK still sweep through the public API with your own key; keys issued before keep their rate limits. To sweep, use zerodust.xyz.

Regenerate or check this table with node scripts/generate-chain-docs.mjs (--check runs in CI); do not hand-edit it. The 20 direct chains are listed by GET https://api.zerodust.xyz/direct/chains: Flare, Cronos, Rootstock, Telos, XDC, Fuse, Monad, opBNB, Lens, Boba, zkSync Era, Flow EVM, HyperEVM, Metis, Vana, Abstract, Immutable zkEVM, Etherlink, Avalanche and Ethereal. Destinations are any EVM chain a bridge delivers native gas to (GET /destinations?fromChainId=), over 100 from Base.

Fees

1% of the swept value, at least $0.05 and at most $0.50; balances under $1 pay 5%, with no minimum. On top: the sweep's gas (and the L1 data fee on rollups) and, cross-chain, the bridge's fee. The signed maxTotalFeeWei caps what can be taken, so a gas spike cannot exceed what you agreed to.

Security

  • No custody: every sweep is one atomic transaction from the wallet itself.
  • The signed intent caps the fee and names the destination; for a bridge route routeHash (keccak256(callData)) binds the signature to that exact call.
  • Every sponsored transaction is simulated before it is sent.
  • ERC-7201 namespaced storage, so the contract's nonce never collides with another EIP-7702 app.
  • Internal security review, 7 rounds, 16 issues found and fixed; contract tests drive a real EIP-7702 delegation and are mutation-verified. Not externally audited, and no audit is currently funded. Details: contracts/SECURITY.md, contracts/SECURITY_REPORT.md.
