Token Launch
ICO vs IDO vs IEO: Token Sale Models Compared
ICO, IEO, and IDO are three models for launching and distributing a new crypto token. An ICO (initial coin offering) sells tokens directly to the public from the project's own platform. An IEO (initial exchange offering) launches the token through a centralized exchange, which vets the project and runs the sale. An IDO (initial DEX offering) launches on a decentralized exchange, with permissionless access and immediate on-chain liquidity. They differ mainly in who runs the sale, how much vetting occurs, and how liquidity is provided.
How each model works
In an ICO, the project runs the sale itself, marketing directly to buyers and handling distribution — maximum control but also maximum responsibility for trust and compliance.
In an IEO, a centralized exchange hosts the sale, performs due diligence, and lists the token, lending credibility and reach in exchange for fees and control.
In an IDO, the token launches on a decentralized exchange or launchpad, often with instant liquidity pools and permissionless participation.
Trade-offs
ICOs offer control but place the full burden of trust, compliance, and distribution on the project. IEOs add exchange vetting and reach but depend on the exchange's terms. IDOs offer speed, open access, and immediate liquidity but less gatekeeping and more exposure to volatility.
Common ground
Regardless of model, a successful launch depends on sound tokenomics, audited contracts, clear disclosure, sufficient liquidity, and compliance with the rules that apply in each jurisdiction. TGE (token generation event) is the general term for the token's creation and distribution across any of these models.
Frequently asked questions
What is the difference between an ICO, IEO, and IDO?
An ICO is run by the project directly, an IEO is run through a centralized exchange that vets the project, and an IDO launches on a decentralized exchange with permissionless access and on-chain liquidity.
What is a TGE?
A TGE (token generation event) is the general term for creating and distributing a new token, which can happen through an ICO, IEO, IDO, or other model.
Which token sale model is best?
There is no single best model; the right choice depends on the project's stage, need for vetting and reach, compliance strategy, and how it wants to provide liquidity.
Are token sales regulated?
Often yes. Depending on how a token is classified and where buyers are located, token sales can be subject to securities and other regulations, which is why legal structuring matters.
