  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

ZeroDust Chain Exit

ZeroDust enables sweeping native gas tokens to exactly zero balance using EIP-7702 sponsored execution. This only works on chains that support EIP-7702 (not all EVM chains).

When to Use This Skill

Activate when the user wants to: Fully exit a blockchain (move all native tokens out) Sweep dust/small balances from wallets Transfer 100% of their balance with zero remainder Empty a wallet completely Consolidate funds from multiple chains

Trigger Phrases

"exit this chain completely" "transfer all my balance from [chain]" "sweep my dust" "empty this wallet" "move everything to [chain]" "leave zero balance"

Supported Chains (25 EIP-7702 Compatible)

API Base URL

https://zerodust-backend-production.up.railway.app

Step 1: Register for API Key (One-Time)

curl -X POST https://zerodust-backend-production.up.railway.app/agent/register \ -H "Content-Type: application/json" \ -d '{ "name": "My OpenClaw Agent", "agentId": "openclaw-unique-id" }' Response: { "apiKey": "zd_abc123...", "keyPrefix": "zd_abc12", "keyId": "uuid", "keyType": "agent", "rateLimits": { "perMinute": 300, "daily": 1000 }, "message": "IMPORTANT: Save your API key now - it will not be shown again!" } Store apiKey as the ZERODUST_API_KEY environment variable.

Step 2: Get Quote

Check the user's balance and fees before sweeping: curl "https://zerodust-backend-production.up.railway.app/quote?userAddress=0xUSER&fromChainId=42161&toChainId=8453&destination=0xDEST" Response: { "quoteId": "uuid", "fromChainId": 42161, "toChainId": 8453, "userAddress": "0x...", "destination": "0x...", "balance": "500000000000000", "balanceFormatted": "0.0005", "estimatedReceive": "485000000000000", "estimatedReceiveFormatted": "0.000485", "totalFeeWei": "15000000000000", "serviceFeeWei": "5000000000000", "gasFeeWei": "10000000000000", "expiresAt": "2026-02-04T16:00:00Z" }

Step 3: Get Authorization Data

Get the EIP-712 typed data for signing: curl -X POST https://zerodust-backend-production.up.railway.app/authorization \ -H "Content-Type: application/json" \ -d '{"quoteId": "uuid-from-quote"}' Response contains typedData (EIP-712 for sweep) and eip7702 (delegation parameters).

Step 4: User Signs Messages

The user must sign: EIP-7702 delegation authorization - Delegates their EOA to ZeroDust contract EIP-7702 revoke authorization - Pre-signed revocation (executed after sweep) EIP-712 sweep intent - Authorizes the specific sweep parameters

Step 5: Submit Sweep

curl -X POST https://zerodust-backend-production.up.railway.app/sweep \ -H "Content-Type: application/json" \ -d '{ "quoteId": "uuid", "delegationSignature": "0x...", "revokeSignature": "0x...", "sweepSignature": "0x..." }' Response: { "sweepId": "uuid", "status": "pending", "txHash": null } Poll GET /sweep/{sweepId} for status updates until status: "completed".

Convenience Endpoint: Combined Quote + Auth

For agents, use this single endpoint to get quote and auth data together: curl -X POST https://zerodust-backend-production.up.railway.app/agent/sweep \ -H "Content-Type: application/json" \ -H "X-API-Key: $ZERODUST_API_KEY" \ -d '{ "fromChainId": 42161, "toChainId": 8453, "userAddress": "0x...", "destination": "0x..." }'

Batch Sweeps (Multiple Chains)

Sweep from multiple chains in one request: curl -X POST https://zerodust-backend-production.up.railway.app/agent/batch-sweep \ -H "Content-Type: application/json" \ -H "X-API-Key: $ZERODUST_API_KEY" \ -d '{ "sweeps": [ {"fromChainId": 42161}, {"fromChainId": 10}, {"fromChainId": 137} ], "destination": "0x...", "consolidateToChainId": 8453 }'

Fees

Service fee: 1% of balance (min $0.05, max $0.50) Gas costs: Paid by ZeroDust, reimbursed from sweep amount User receives: ~97-99% of balance (varies by gas prices)

Rate Limits

Agent keys: 300 requests/minute, 1000 sweeps/day Contact ZeroDust for higher limits

Error Codes

Example Agent Conversation

User: "I want to move all my ETH from Arbitrum to Base" Agent: Call /quote to check balance and fees Show user: "You have 0.005 ETH on Arbitrum. After fees (~1%), you'll receive ~0.00495 ETH on Base. This requires signing 3 messages. Proceed?" If yes, call /authorization to get typed data Request wallet signatures (EIP-7702 delegation, revoke, and EIP-712 sweep) Submit to /sweep with signatures Poll status until complete Confirm: "Done! Your Arbitrum balance is now exactly 0. 0.00494 ETH received on Base."

Important Notes

EIP-7702 Required: User's wallet must support EIP-7702. Most modern wallets do as of 2026. Signatures Required: Sweeps require user wallet signatures. ZeroDust never has custody. Zero Balance Result: After sweep, source chain balance is EXACTLY zero. Cross-Chain: Sweeps can go to any supported destination chain via Gas.zip bridging. Not All EVM Chains: Only the 25 chains listed above support EIP-7702. Do not attempt sweeps on unsupported chains.
