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
- Send SOL to this wallet (1 transaction)
- Transfer tokens out (1 transaction)
- 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)
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
- Fee payer signs to authorize fee payment
- Source wallet signs to authorize token transfer
This is a native Solana feature – no hacks or workarounds.

|---|
| 10 | ~0.002 SOL |
| 50 | ~0.010 SOL |
| 100 | ~0.020 SOL |

- Whether destination token account exists
- Token-2022 vs standard SPL tokens

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
- Keep one funded wallet – Designate a “gas bank” wallet with SOL for fees
- Check estimates – Review the gas estimate before sweeping large numbers
- Sweep by token – Do one token at a time for cleaner tracking
- Monitor progress – Watch for failed transactions and retry if needed
Why This Matters
Gasless Sweep is bundl’s killer feature because:
- No one else has it – Other wallet managers don’t support fee payers
- Saves hours – 50 wallets = 100 manual transactions vs 1 click
- Saves money – No need to spread SOL across wallets
- Unlocks stuck tokens – Tokens you couldn’t move are now accessible
This single feature justifies the Pro license for anyone managing multiple wallets.
