Wrapping — why BMB becomes WBMB

Why wrap

Mainnet BMB lives on a proof-of-work chain like Bitcoin: sturdy, but not built to run smart contracts or plug directly into services like Uniswap. So Mobick wraps BMB into a token on an Ethereum-style (EVM) chain: WBMB (Wrapped BMB).

Oh Taemin has explained this several times:

• Two tracks (19 September 2026) — mainnet BMB is the mined base and the measure of supply; interest, trading and smart contracts run through WBMB. “Let’s move to a culture of supply and mining in BMB, everyday trading in WBMB.”
• Listings and airdrops (28 February 2026) — exchanges avoid mainnet coins, so future listings and airdrops will use the WBMB family.
• Ready for public mining (20 August 2026) — if mainnet confirmations slow after going public, people can trade WBMB and swap back later.

How the 1:1 is kept

Mobick’s wrapping is custodial: when you send BMB to MobickOne, the operator (Otaverse) holds it and sends the same amount of WBMB from a pre-minted stock to your BSC address. To unwrap, you return WBMB (back to stock) and get the held BMB back. WBMB is not minted on the fly. No new BMB is created, so BMB supply is unchanged.

There is, however, no contract locking BMB on mainnet. Whether held BMB and outstanding WBMB match 1:1 is kept by the operator, not enforced by the chain — strictly, WBMB is closer to a custodial token than to lock-and-mint wrapping.

1. Wrap. Hand B M B to Mobick One, and the operator holds it and hands out the same amount of W B M B from a pre-minted stock. The one to one is kept by the operator, not the chain.
2. Unwrap. Give the W B M B back, and the operator takes it back and returns the B M B it was holding.
3. Predict. Your turn to predict. If Mobick One stops the swap, can W B M B still become B M B? Answer: it can’t. No. Unwrapping only works while Mobick One keeps it open. The backing B M B is held off-chain by the operator. Uniswap only swaps W B M B for other tokens; it can't release B M B.
4. Safeguards. Custodial tokens usually prove the one to one with published reserve addresses, multi-signature control and timelocks. This site can't guarantee W B M B's one to one swap.

The narration is synthesized speech.

The backing BMB is held off-chain by the operator (Otaverse), so turning WBMB back into BMB works while MobickOne keeps that swap open. Custodial tokens usually let anyone check the 1:1 through published reserve addresses, multi-signature control and timelocks.

Wrapping in MobickOne

The official MobickOne app includes BMB↔WBMB swaps.

1. Receive mainnet BMB at your MobickOne BMB address.
2. Swap BMB → WBMB: 1:1, 0.01–200 per swap, no fee (as of September 2026).
3. The WBMB lands at your MobickOne BSC address. To send it to another EVM wallet you need a little BNB for BSC gas.
4. To unwrap, swap WBMB → BMB.

Base WBMB can also be swapped to BSC WBMB in MobickOne. With EVM activity consolidating on BSC and Base to be wound down, think of new WBMB as BSC WBMB.

Summary

• WBMB is a BSC token the operator (MobickOne) hands out 1:1 from a pre-minted stock of 500,000 against BMB it holds. BMB supply is unchanged, but the 1:1 is kept by the operator, not the chain.
• Two tracks: mining and supply in BMB, programs and trading in WBMB; future listings and airdrops in the WBMB family.
• Wrap 1:1 in MobickOne (0.01–200 per swap); BSC gas is paid in BNB.
