Centralized Exchange (CEX) Token

BNB began in 2017 as a Binance fee token, left Ethereum for Binance Chain in 2019 and became gas and stake on BSC in 2020. The 2022 Token Hub exploit and validator-coordinated halt exposed the human decisions behind its two-chain design; the 2024 Fusion and two burn mechanisms reshaped it again.

LEO began as iFinex’s one-billion-dollar 2019 financing token. Its shrinking supply comes from exchange-funded market purchases, not a one-dollar redemption. Trading-fee discounts ended in 2025, while conditional funding, affiliate, deposit and withdrawal benefits remain; multisignatures still hold controller and issuer permissions on Ethereum and Vaulta.

WBT began in 2022 as WhiteBIT’s exchange-benefit token, became the gas coin of a company-authorized PoA chain in 2023, and is now waiting for that chain’s planned replacement by an Ethereum L2. Its useful rights still split between WhiteBIT account rules, SoulDrop conditions and onchain contracts.

CRO's defining history is a supply reversal: Crypto.com celebrated a 70 billion-token burn in 2021, then Cronos governance restored 70 billion to a Strategic Reserve in 2025. The token now connects Cronos POS and Cronos EVM, while the zkEVM Alpha is winding down and the scope of the new Cronos App remains a product question separate from token-holder rights.

OKB began with a one-billion-token design, shed 700 million unissued units, split chain duties with OKT, and later became X Layer's gas asset with a stated 21 million supply. The current implementation lacks mint and burn methods, but its Ethereum proxy remains upgradeable and OKX's fee-benefit descriptions vary by market and date.

HTX is a fixed-supply TRON token launched after Huobi had already renamed its exchange. Its DAO offers voting and exchange benefits, yet formal proposals, execution, burns and staking controls remain split among a hybrid committee, an operations team and HTX Exchange.

BGB began as Bitget's exchange token, absorbed wallet token BWB, and moved its roadmap to Morph Foundation. Morph still lists ETH as its native network currency, while its current AltFee documentation supports paying gas with BGB. This alternative payment route does not establish a complete native-currency migration or holder governance.

KCS is KuCoin's policy-driven exchange token and KCC's native gas asset. Its history includes a 2021 name and Ethereum-contract swap, changeable fee and staking programs, monthly revenue-based burns, administrator blacklist powers, and operator risk sharpened by KuCoin's 2025 U.S. guilty plea.

GateToken (GT) began as an exchange-distributed token, became Gate Chain's native consensus asset, and now pays gas on Gate Layer. Those roles share a symbol but differ in issuer history, holder rights, validator power, supply accounting and bridge control.

NEXO is a fixed-supply Ethereum token whose valuable functions mostly begin after it enters a Nexo account. A 2021 vote ended profit dividends in favor of daily account interest; current benefits remain conditional and changeable, and the token itself promises neither equity nor redemption.

MX is MEXC's Ethereum exchange token at 0x11eef04c884e24d9b7b4760e7476d06ddf797f36. Its contract now has 409,024,834 MX outstanding; MEXC reports 91,837,334 circulating, 317,187,500 locked and 590,975,166 burned, while current benefits are account-based programs rather than equity or a claim on exchange reserves.

GRX is the native asset of GroveX-backed chain 1110. Its genesis and validator code are public, but current network control and the promised profit-linked holder program remain only partly verifiable.

BTSE Token began as a 200 million-unit Liquid asset and later gained a role-controlled Ethereum wrapper. Its documented uses are changeable BTSE account benefits. Public records do not reconcile live cross-network backing, current contract administrators or a token-holder claim on the exchange or its licensed local entities.

SAFEbit’s SAFE is a company-linked BNB Chain token whose contract calls itself SAFEcoin. Its one-billion mint is fixed and burnable, yet an owner key can blacklist addresses; exchange staking, market access and campaign rewards remain governed by corporate terms rather than token-holder votes.

BP arrived after Backpack had already built a self-custodial wallet, Mad Lads and a regulated exchange group. Its 1 billion allocation, staking discounts and conditional SPV-equity route are company programs; the Solana mint still retains live mint and freeze authorities, and BP itself is neither equity nor DAO control.

ARKM is the Ethereum token at 0x6E2a…b050 used for Arkham's intelligence marketplace, rewards and some exchange fee discounts. Its documents describe governance and a one-billion allocation, while the upgradeable token owner retains mint, pause and upgrade powers that holders do not share.

bitcastle Token (BCE) is a 2025 exchange token on Sui with a second BNB form. CASTLE and BCAST had already served overlapping exchange products, yet no reviewed document converts either balance into BCE.
