An IEO (Initial Exchange Offering) is a token sale conducted directly on a centralised cryptocurrency exchange, with the exchange acting as intermediary, vetter, and distributor. Unlike ICOs (project-direct, minimal oversight) and IDOs (DEX-based, immediate liquidity), IEOs are managed entirely by the exchange — providing the highest level of project screening, broadest distribution reach, and guaranteed listing on a liquid market upon completion.
How an IEO Works: Step by Step
- Exchange application: The project applies to the exchange's launchpad programme. The exchange conducts due diligence: team verification, legal review, tokenomics assessment, and technical audit. Acceptance rate is far lower than ICOs or basic IDOs — Binance Launchpad accepts under 1% of applications.
- Sale announcement: The exchange announces the IEO with terms: token price, total raise, allocation per user, and eligible account requirements (minimum BNB holdings for Binance Launchpad, minimum KCS for KuCoin Spotlight).
- Subscription period: Account holders subscribe — committing funds toward the allocation. On most platforms, the final allocation is calculated pro-rata based on how many platform tokens (BNB, KCS) each subscriber holds.
- Distribution: Tokens are distributed directly to exchange wallets. No separate wallet interactions, no gas fees, no bridge complexity.
- Exchange listing: The token lists on the exchange's spot market, often within hours to days of IEO completion.
IEO vs. ICO vs. IDO
- ICO: No intermediary. Highest project risk. No guaranteed listing. Weakest vetting. Historically high scam rate.
- IDO: Launchpad as intermediary. DEX-based. Immediate DEX liquidity at TGE. Requires launchpad token staking. Variable vetting quality.
- IEO: Exchange as intermediary. CEX-based. Exchange spot listing. Broadest retail reach. Highest vetting standards. KYC and account requirements on the exchange.

Important: IEO exchange vetting reduces but does not eliminate investment risk. All IEO tokens can lose value after listing. This guide is educational only. CryptoPresaleNews.com is not a licensed financial advisor.
