Initial exchange offering (IEO)

An initial exchange offering is a token sale run on a centralised exchange's own platform, where the venue handles the listing, takes the payments and performs some vetting before the sale opens. Buyers subscribe from accounts the exchange already knows, and spot trading usually starts on that venue within days. The exchange is the intermediary the ICO removed and the counterparty an IDO never had.

You are buying distribution and operational cover, and paying for it in fees, allocation and dependence on one venue. What you are not buying is a view on your token's legal status, because a listing decision is a commercial one and it changes nothing about the analysis underneath.

What the venue actually takes on

Banxa's account of how the format arrived is the short version: after the ICO market collapsed, exchanges repackaged public sales as IEOs, where the exchange did the listing and some of the vetting.1 Three functions move across at once. The venue runs the sale page, receives and holds the money, and screens the project before agreeing to any of it.

Allocation is the piece founders underestimate. Because subscribers are existing account holders, the exchange can ration by lottery, by tier, or by requiring a holding of its own asset. Binance positions Launchpad as the structured fundraising venue, similar in concept to an initial exchange offering, and runs Launchpool as a separate mechanic entirely, where users lock BNB and other tokens to receive new tokens at no extra cost.23 Those are different products and the terms differ accordingly, so read which one you are actually being offered.

For the buyer it is the mirror image of a self custody sale. Funds sit with the exchange, identity checks were done at account opening, and a failed transaction is a support ticket rather than a lost private key.

Who is carrying what

Split the risks by who holds them, because the marketing rarely does. The project carries fee and allocation cost, a buyer set defined by one venue's user base, and a listing whose future depends on that venue's commercial priorities. Ask for the fee schedule, the token allocation to the exchange, and any delisting terms in writing.

The exchange carries reputational exposure and the vetting work, which is exactly why it charges. That vetting is commercial diligence on a business it is about to put in front of its users. It is not a regulatory review, it is not disclosed to buyers in the way a prospectus would be, and it does not transfer to the project any finding it makes.

The buyer carries token risk and platform risk together. Custody sits with the venue during the sale and often afterwards, so an exchange failure and a project failure are two separate ways to lose the same position. Our initial DEX offering entry covers the opposite trade, where self custody removes the platform risk and makes every buyer error final.

Against an ICO and against an IDO

One variable separates all three: who stands between the project and the buyer. In an ICO nobody does. The project published a whitepaper and an address, buyers sent funds directly, and no broker or prospectus sat in between.1 Every obligation that an intermediary would normally absorb stayed with the issuer, usually unnoticed.

In an IDO the intermediary is a smart contract and a pool. Settlement is onchain from self custody wallets, price discovery starts in the same block the pool is funded, and no party can pause anything. In an IEO the intermediary is a company with a compliance department, an order book, market makers under quoting obligations, and the operational ability to delay a listing.

So the choice is about which failure modes you want. An IEO trades launch control and margin for a market that opens with professional depth behind it. An IDO trades that depth for reach that depends on no listing committee. Neither creates demand that was not there.

A listing is not a classification

This is the most expensive misreading in the category. Whether a particular sale is an offer of securities turns on the facts of that offering and the law of each jurisdiction it reaches. A venue agreeing to host it changes neither, and no exchange offers an opinion that it does.

In our view the risk runs the other way. An exchange sale concentrates a documented, timestamped, fully identified record of every buyer, every payment and every piece of marketing in one place, which is helpful if the analysis holds and unhelpful if it does not. That analysis belongs to your counsel. This page is design reference, not legal advice, and nothing here recommends buying, selling or holding any token.

What to settle before the term sheet

Five things, in writing. The total cost, counting fees and any token allocation to the venue. The size and price of the sale tranche. Whether that tranche vests or lands unlocked, since an unlocked sale tranche goes straight into effective sellable float. The market making arrangement and who pays for it. And what happens to the listing if the exchange changes its mind.

Then the question the launchpad conversation will not raise. A venue can put your token in front of its users once. Whether they stay depends on whether the product underneath produces something worth paying for, and no listing has ever fixed that.

Common questions

What is an initial exchange offering?

An IEO is a token sale hosted on a centralised exchange, where the venue lists the sale, handles payments and does some vetting of the project first.1 Participants subscribe from existing exchange accounts, so identity checks are already done, and allocation is usually rationed by lottery, by tier, or by requiring a holding of the exchange's own token. Spot trading normally follows on the same venue.

How is an IEO different from an ICO and an IDO?

By who sits in the middle. An ICO had nobody: the project published an address and buyers sent funds directly, with no broker or prospectus in between.1 An IDO settles on a decentralised exchange from self custody wallets and seeds a trading pool in the same event. An IEO puts a company in the middle that vets, takes payment, custodies and lists, and charges for all four.

Does an exchange listing change a token's legal status?

No. Whether an offering involves securities is decided on the facts of that offering and the law of each jurisdiction it reaches, and hosting the sale on a venue does not alter either. Exchange vetting is commercial diligence on a business, not a regulatory review, and the venue does not publish a finding you can rely on. That analysis stays with your counsel.
