Migration moves everything out of a pile of old wallets into one new address. It is close to sweeping, except it scans first, can sponsor gas, and works through tokens before native coin — the native coin has to stay long enough to pay for gas.
- Paste source wallets and a targetYou can paste several private keys. The target accepts a standard 0x address, or 40 characters with the 0x left off.
- Choose scan settingsThe value threshold filters out dust; 0 moves everything. Changing any setting asks you to scan again — the list reflects the moment you scanned.
- Read the review listThe scan lists every wallet, every asset, the amount, and the fee for this run. Rows with a zero balance are dust: skip them.
- Decide on gas sponsorshipIf the source wallets hold no native coin at all, turn on gas sponsorship: one funded wallet fronts gas for them. That wallet also needs enough for the float plus gas on its own transactions — if it is short, nothing is sent at all.
- Run it and watch the logThe log shows each wallet as it moves. Tokens go first, native coin last, so you never end up with funds gone and gas unpaid.
- Export the resultThe run exports as CSV when it finishes. One failed wallet does not abort the batch; the log says why it failed.
Careful · The fee is charged per token
Every token migrated costs a fee; native coin does not. When a wallet holds many assets, add the fees up first and decide whether to do it in stages.
