Values you fill in

ZERODUST_API_URL env
Custom API URL (defaults to https://api.zerodust.xyz)
ZERODUST_API_KEY secret env
API key for higher rate limits. An agent can issue itself one with the zerodust_register_api_key tool, with no human signup step.
ZERODUST_ALLOW_EXECUTE env
Set to "true" to enable the sweep tools. Sweeping moves real funds, so it is off by default and also requires one of the four signing-key variables below.
ZERODUST_SIGNER_MODULE env
Path or specifier of a module whose default export returns a viem LocalAccount. This is how Turnkey, Privy, AWS KMS or any other custody service is used, without a raw key ever reaching this server.…
ZERODUST_KEYSTORE_FILE env
Path to an encrypted V3 keystore (as produced by `cast wallet import` or geth). Requires ZERODUST_KEYSTORE_PASSWORD_FILE or ZERODUST_KEYSTORE_PASSWORD.
ZERODUST_KEYSTORE_PASSWORD_FILE env
Path to a file containing the keystore password, so the password never enters the MCP config.
ZERODUST_KEYSTORE_PASSWORD secret env
Keystore password inline. Prefer ZERODUST_KEYSTORE_PASSWORD_FILE.
ZERODUST_PRIVATE_KEY_FILE env
Path to a file containing a hex private key, so the key stays out of the MCP config.
ZERODUST_PRIVATE_KEY secret env
Private key for the agent's own wallet, inline. Used locally to sign the EIP-7702 authorization and EIP-712 sweep intent; never transmitted, only the resulting signatures are sent. The signer-module,…
ZERODUST_ALLOWED_DESTINATIONS env
Comma-separated allowlist of sweep destinations. When unset, funds can only be swept to the agent's own address.

Common questions

Is Zerodust safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ZERODUST_API_KEY, ZERODUST_KEYSTORE_PASSWORD, ZERODUST_PRIVATE_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.1) reached the registry 36 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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; Fraxtal's FRAX arrives on Ethereum as the FXS token.

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.

Package	Use
`@zerodust/sdk`	TypeScript client and agent (`createAgentFromPrivateKey`); the website uses it
`@zerodust/mcp-server`	MCP server, run locally (paused)
`@zerodust/langchain`	LangChain tools (paused)
`@zerodust/ai-sdk`	Vercel AI SDK tools (paused)

Contracts

All are immutable: no admin functions, no upgrades, no pause (the paymaster's owner can only change its approver and withdraw its float). The sweep contract's sponsor address is fixed in its bytecode.

Regenerate or check this table with node scripts/generate-chain-docs.mjs (--check runs in CI); do not hand-edit it. The 19 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 and Avalanche. 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.
