Burning retires your old STBU so the same supply isn't counted twice on two chains, and it creates a public on-chain receipt proving the tokens were yours. That receipt is what you claim your new STBU against, 1:1.
To the exact same wallet you burned from, on Base. That's why you must burn from a wallet you control on Base.
No. You can't claim from an address you don't hold the keys to. Withdraw your STBU to a self-custody wallet first, then burn from there.
From 15 September 2026 – the same day the burn window closes. Burn your old STBU before 15 September; from that date you mint your new STBU on Base, 1:1, to the same wallet.
Yes. The burn window closes 15 September 2026 – burn your old STBU before then. Claiming (minting) on Base opens the same day, 15 September, and stays open afterward. Only ever act on dates shown here at stbu.stobox.io or on official Stobox channels.
Proving wallet ownership is free. You pay the normal network fee (gas) to send the burn, and a small Base fee to claim. Stobox charges nothing.
1:1 – one old STBU burned equals one new STBU on Base.
Contact official Stobox support with proof. After verification, Stobox can allocate your tokens to a wallet you control (approved by two team members). It then claims like any other balance.
Only use stbu.stobox.io, only send the official STBU token to 0x…dEaD, and never share your seed phrase. Stobox will never DM you first or ask you to "sync/validate" your wallet elsewhere.
We can't give tax advice. A 1:1 migration may or may not be taxable where you live – check with a qualified professional.
Yes – claiming is an on-chain transaction, so keep a small amount of ETH on Base for gas. It's usually only a few cents. Stobox charges nothing on top.
Yes. Every confirmed burn – on any of the four chains, in any number of transactions – adds to the same eligible balance for that wallet. Burn whatever you hold, any time before the 15 September 2026 deadline.
No. It's a 1:1 swap of the same token onto one chain. You end up with the same number of STBU; nothing is diluted or revalued by the migration itself.
No. STBU is not listed on a centralised exchange and we have no exchange listing plans at this time. Legacy STBU was delisted, Stobox runs no pool for it, and nothing sent to an exchange is credited. You claim yourself, from the wallet that burned.
After you claim, add the Base STBU contract address to your wallet as a custom token. You can copy it from the About STBU tab.
