OKB: after the 2025 Reset, a hard 21M cap.
The 2025 OKX Reset burned ~235M+ OKB, cutting total supply to 21M — BTC-style. Combined with continued buyback-and-burn, OKB has the most aggressive deflationary mechanics of any exchange token we cover.
The setup
OKB is OKX's exchange token. Originally ~300M supply in 2018. OKX ran quarterly buybacks-and-burns for years, then in 2025 executed the "OKB Reset" — a mass burn that destroyed ~235M+ OKB and reduced total supply to 21M with a hard cap. OKB Chain (X Layer) is OKX's L2 that uses OKB as gas; the token bridges between Ethereum mainnet and X Layer.
- Total supply: ~21M OKB (hard cap post-Reset)
- Ethereum mainnet contract holds ~429K OKB (rest on X Layer + bridges)
- Price ~$82.41 → market cap ~$1.73B
- No protocol inflation (cap enforced) · No team vesting today (original vest ended; Reset burned the rest)
- Quarterly buyback-and-burn funded by OKX exchange revenue
The sell ledger
What the design predictably puts on the market.
Inflation: zero. Hard 21M cap.
Vesting: zero. 2018 distribution (60% team/foundation 5y vest, 30% ICO, 10% community). Vest done 2023; 2025 Reset burned most of the remaining team allocation.
Tag B is OKX corporate treasury, with structural opacity (same as BNB). Exchange custodial wallets are excluded per the framework rule (they belong to depositors). The actually-discretionary OKX corporate treasury is not separately disclosed in an identified multisig. Honest read: small Tag B not enumerable to ONDO Foundation Safe precision.
The buy ledger
What the design predictably takes off the market.
Buyback + burn is the structural strength. Unlike BNB's Auto-Burn (destroys from a team pool, not market), OKX's mechanic buys on the open market before burning. True Tag-A revenue-backed buyback — rare in our coverage (alongside HYPE's Assistance Fund and SKY's surplus buffer).
Volume varies with OKX revenue. Historically low single-digit millions of OKB per quarter at recent prices; post-Reset 21M cap means each buyback now removes a larger % of supply.
Net position
Sell ledger functionally zero (cap + no vest). Buy ledger: real Tag-A market buying via the quarterly buyback-and-burn. Net structural read: favorable, the same shape as BNB (deflationary by design) but with a true open-market buyback that BNB lost when Auto-Burn replaced the pre-2021 mechanic.
The only structural risk
Same as BNB: opacity. OKX holds OKB outside identified custodial wallets, and the framework cannot fully read this. If a future transparency disclosure reveals a separately-held corporate treasury, that becomes a new Tag B line.
What to watch
1) Quarterly OKB buyback-and-burn announcements at okx.com/help-center/okb. 2) OKX exchange revenue trend. 3) X Layer (OKB Chain) gas demand growth. 4) Any OKX transparency disclosure of separately-held corporate treasury.
Data note. 21M total supply per CoinGecko cross-check (matches OKX's post-Reset published cap). Ethereum mainnet contract balance read directly via eth_call → totalSupply() on the OKB ERC-20 (0x7523…2a86c); the mainnet contract holds only ~429K OKB with the bulk on X Layer + bridges. OKX corporate vs. custodial split flagged as a known opacity.
