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).

Store apiKey as the ZERODUST_API_KEY environment variable.
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",

"toChainId": 8453,

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).
The user must sign:
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".
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..."
}'
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
}'

/quote to check balance and fees/authorization to get typed data/sweep with signaturesEIP-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.
