Gasless Sweep is bundl’s most powerful and unique feature. It solves a problem every multi-wallet user faces: tokens stuck in wallets with no SOL for gas.
Gasless Sweep is a Pro feature.

​
The Problem

You’ve received airdrops, traded across multiple wallets, or accumulated tokens over time. Now you want to consolidate. But there’s a problem: 
Wallet: airdrop-15
  - BONK: 500,000 tokens ($50)
  - SOL: 0.000000

ERROR: Insufficient SOL for transaction fee
The wallet has tokens but no SOL. To transfer the tokens, you’d need to:
  1. Send SOL to this wallet (1 transaction)
  2. Transfer tokens out (1 transaction)
  3. Repeat for every wallet
For 50 wallets, that’s 100+ transactions.

​
The Solution

With Gasless Sweep, a single “fee payer” wallet covers gas for ALL transfers. 
Fee Payer: main-wallet (5.0 SOL)
  ↓ pays gas for ↓

Wallet 1: airdrop-1 (0 SOL) → 500,000 BONK → destination
Wallet 2: airdrop-2 (0 SOL) → 750,000 BONK → destination
Wallet 3: airdrop-3 (0 SOL) → 250,000 BONK → destination
...
Wallet 50: airdrop-50 (0 SOL) → 600,000 BONK → destination

Total Gas: ~0.01 SOL (paid by main-wallet)
One wallet, one gas payment, 50 tokens swept.

​
How It Works

​
Technical Explanation

Solana transactions support separate fee payers. The transaction structure is: 
Transaction:
  - Fee Payer: main-wallet (pays ~0.000005 SOL)
  - Signer 1: airdrop-1 (authorizes token transfer)
  - Instructions:
    - Create destination token account (if needed)
    - Transfer tokens from airdrop-1 to destination
Both wallets sign the transaction:
  • Fee payer signs to authorize fee payment
  • Source wallet signs to authorize token transfer
This is a native Solana feature – no hacks or workarounds.

Step-by-Step Guide

1

Select Source Wallets

Check the wallets you want to sweep from. These can have 0 SOL.
2

Open Token Sweeper

Click [sweep tokens] in the selection action bar.
3

Select Token

Choose which token to sweep (BONK, USDC, etc.).The dialog shows total tokens across all selected wallets.
4

Select Destination

Choose which wallet receives the tokens.
5

Select Fee Payer

This is the key step. Choose a wallet with SOL to pay gas.
Fee Payer (optional):
[main-wallet ▼]                    5.0 SOL available

ℹ️ This wallet will pay gas for all transfers.
   Estimated: ~0.01 SOL for 50 wallets
The fee payer must have enough SOL for all transaction fees.
6

Sweep

Click [sweep]. Watch as each wallet is swept:
Sweeping BONK from 50 wallets...

✓ airdrop-1    500,000 BONK
✓ airdrop-2    750,000 BONK
✓ airdrop-3    250,000 BONK
...

Complete! 25,000,000 BONK swept to main-wallet
Gas paid: 0.0085 SOL

​
Fee Estimation

WalletsEstimated Gas
10~0.002 SOL
50~0.010 SOL
100~0.020 SOL
Actual fees depend on:
  • Network congestion
  • Whether destination token account exists
  • Token-2022 vs standard SPL tokens
bundl shows an estimate before you confirm.

​
Error Handling

​
Fee Payer Has Insufficient SOL

✗ Error: Fee payer needs more SOL.
  Has: 0.005 SOL
  Needs: ~0.010 SOL
Solution: Add more SOL to the fee payer wallet or select a different fee payer.

​
Some Wallets Have No Tokens

Sweep Complete

  ✓ Succeeded: 48 wallets
  ⊘ Skipped: 2 wallets (zero balance)
  ✗ Failed: 0 wallets
Wallets with zero balance of the selected token are automatically skipped. This is normal.

​
Transaction Simulation Failed

✗ Transaction simulation failed
  Fee payer does not have enough SOL for transaction fees.
bundl simulates each transaction before sending to catch errors early.

​
Use Cases

​
Airdrop Consolidation

Received tokens across 100 wallets? Sweep them all without funding each wallet.

​
Trading Wallet Cleanup

After trading across many wallets, consolidate tokens even if you’ve already moved the SOL out.

​
NFT Revenue Collection

Royalties from NFT sales often land in random wallets. Sweep them all.

​
Migrating to New Wallet

Moving to a new main wallet? Sweep everything from old wallets without leaving SOL behind.

​
Best Practices

  1. Keep one funded wallet – Designate a “gas bank” wallet with SOL for fees
  2. Check estimates – Review the gas estimate before sweeping large numbers
  3. Sweep by token – Do one token at a time for cleaner tracking
  4. Monitor progress – Watch for failed transactions and retry if needed

​
Why This Matters

Gasless Sweep is bundl’s killer feature because:
  1. No one else has it – Other wallet managers don’t support fee payers
  2. Saves hours – 50 wallets = 100 manual transactions vs 1 click
  3. Saves money – No need to spread SOL across wallets
  4. Unlocks stuck tokens – Tokens you couldn’t move are now accessible
This single feature justifies the Pro license for anyone managing multiple wallets.
