Sweep Recovery

Dust tokens scattered across chains are expensive to track and worthless individually. 0xRadar’s sweep quote endpoint estimates the gas cost to consolidate them.

​
When to use sweep quotes

  • Wallet has 20+ small balances across L2s
  • Preparing a treasury migration
  • Cleaning up a hot wallet before rotation
  • Reviving an old wallet from 2020-2023

​
Step-by-step

​
1. Get the quote

curl -H "X-API-Key: YOUR_API_KEY" \
  "https://api.0xradar.app/v1/sweep-quote/0xYOUR_ADDRESS?chains=eth,arb,base,polygon&target_chain=base"

​
2. Evaluate cost vs value

{
  "summary": {
    "total_gross_value_usd": "18320.18",
    "total_gas_cost_usd": "0.67",
    "total_net_value_usd": "18319.50",
    "recommendation": "sweep"
  }
}
If recommendation is "wait", the value doesn’t justify gas cost yet.

​
3. Execute the sweep (off-API)

0xRadar provides the quote only. To execute:
  1. Use your preferred bridge + DEX aggregator (e.g. Across + 1inch)
  2. Swap dust to the target chain’s native gas token or a stablecoin
  3. Consolidate to your target wallet

​
4. Verify post-sweep

Query /portfolio after the operation to confirm balances moved: 
curl -H "X-API-Key: YOUR_API_KEY" \
  "https://api.0xradar.app/v1/wallet/0xYOUR_ADDRESS/portfolio?chains=base"

​
Safety notes

  • Always simulate transactions in Tenderly before sending
  • Be aware of bridge latency — funds may not arrive for 5–30 minutes
  • Some tokens have transfer taxes or blacklists that prevent sweeping
  • Test with small amount first ($1-10)
