How do I migrate Stobox Token (STBU) to Base, and is the new contract safe?

STBU moved onto one canonical contract on Base on 15 September 2026 (0xe0c0F44A84CC4a60206360006ebA237a5e8fC2dd – verified on BaseScan, immutable, 250M hard cap). The burn window closed on 15 September 2026 and does not reopen. Holders who burned in time claim 1:1 at stbu.stobox.io until 31 December 2026, 23:59 UTC.

Stobox Token (STBU) has lived on four blockchains – Ethereum, BNB Chain, Polygon and Arbitrum. The migration replaces those four deployments with a single canonical contract on Base, Ethereum’s leading Layer 2, so there is one token and one address instead of four copies.

How the migration works

Status: the burn window closed on 15 September 2026 and does not reopen. The three steps below describe how it worked; claims for tokens burned in time stay open until 31 December 2026, 23:59 UTC.

A token cannot move between blockchains directly, so the migration takes the old token permanently out of circulation and mints the same amount fresh on Base. It is three steps, and it is non-custodial throughout – Stobox never holds your tokens.

1. Burn. At stbu.stobox.io you send your old STBU to a burn address (0x…dEaD) that nobody owns and nobody can spend from. This permanently retires the tokens, and the burn transaction is your public on-chain receipt.
2. Confirm. The system detects your burn on-chain automatically and credits your eligible balance. There is no form and nothing to send to anyone.
3. Claim. Since 15 September 2026 you can mint the same amount of new STBU, 1:1, directly to your own wallet on Base.

The exchange is exactly 1:1 and you pay only ordinary network gas for your own transactions.

The details that matter

• Canonical contract:0xe0c0F44A84CC4a60206360006ebA237a5e8fC2dd on Base, verified on BaseScan.
• Token / symbol / decimals: Stobox Token / STBU / 18.
• Supply: hard-capped at 250,000,000 forever. The only way new tokens are ever created is a verified 1:1 migration claim – no owner mint, no cap increase.
• Immutable: the contract cannot be upgraded. An emergency pause exists for safety, and un-pausing requires multi-signature approval.
• Governance: a 2-of-3 multi-signature wallet, with the migration signer held in a hardware security module.
• Standard: a modern ERC-20 with gasless approvals (Permit / EIP-2612).

Key dates and staying safe

The burn window closed at 15 September 2026, 00:00 UTC, the instant claiming opened. Claims for tokens burned in time close on 31 December 2026, 23:59 UTC.

Migrate only at stbu.stobox.io, and always confirm the contract address matches the one above. Anyone asking you to pay to migrate, or for an “unlock payment”, is running a scam. Stobox will never DM you first and will never ask for your seed phrase or private key.

Gene Deyev’s take

Four contracts on four chains was a tax we were charging our own holders – fragmented liquidity, four things to verify, four ways to get it wrong. Consolidating STBU onto one immutable, verified contract on Base is the honest version of the token: a fixed cap, no owner mint, and every claim provable on a public explorer. We deliberately made the migration non-custodial, so holders retire their own tokens and mint the new ones themselves. Nobody should ever have to trust us for something the chain can prove.
