An IDO (Initial DEX Offering) is a token sale conducted through a decentralised exchange (DEX) or a dedicated IDO launchpad platform — unlike ICOs (conducted directly by the project) or IEOs (conducted by a centralised exchange). The defining characteristic of an IDO: tokens are immediately available for trading on the DEX from the moment the sale concludes, with liquidity added to the DEX pool at TGE. This immediate liquidity is both IDOs' greatest advantage over ICOs and the source of their unique risks.
How an IDO Works: Step by Step
- Project onboarding: The project applies to an IDO launchpad, undergoes vetting (varying depth by platform), and agrees to launchpad terms including allocation percentage for the platform community
- Whitelist registration: Eligible investors register for the IDO whitelist — typically requiring launchpad token staking (POLS for Polkastarter, DAO for DAO Maker) and KYC completion
- Allocation determination: The launchpad determines each investor's maximum purchase amount based on staking tier, lottery outcome, or pro-rata formula
- Sale execution: Investors send accepted currencies (ETH, BNB, USDC) to the IDO smart contract during the sale window to receive token allocations
- TGE and DEX listing: At the close of the sale, the project adds initial liquidity to the DEX (Uniswap, PancakeSwap, Raydium) and tokens become immediately tradeable. This happens simultaneously with token distribution to IDO participants
- Vesting schedule: IDO allocations may be fully liquid at TGE or subject to a vesting schedule depending on launchpad and project terms
IDO vs. ICO vs. IEO
- ICO (Initial Coin Offering): Direct project fundraise with no intermediary. Less vetting, less infrastructure, more regulatory risk for the project. No guaranteed listing or immediate liquidity.
- IDO (Initial DEX Offering): Launchpad-managed sale on decentralised infrastructure. More vetting than typical ICO, immediate DEX liquidity at TGE, community distribution focus. Launchpad token staking required for access.
- IEO (Initial Exchange Offering): Centralised exchange manages the sale on their platform. Highest vetting standards, built-in exchange listing, largest reach but most restrictive access requirements.
Key IDO Advantages for Investors
- Immediate liquidity: Unlike direct presales (tokens locked until TGE, then listed later), IDO tokens are typically listed on the DEX simultaneously — faster access to trading
- Decentralised access: No exchange account required (for DEX-native IDOs), no geographic restrictions beyond wallet-level
- Price discovery: Immediate market pricing reflects real supply and demand at TGE rather than a project-controlled listing price
- Launchpad vetting: Even basic launchpad screening eliminates the most obvious scam projects
Key IDO Risks
- Low float at TGE: Some IDOs list only 5-10% of total supply initially — easy to manipulate, with future dilution from unlocks
- Bot front-running: FCFS IDOs can be front-run by bots; MEV extraction from early TGE trading reduces returns for human participants
- Launchpad quality variance: "IDO" can mean anything from thorough DAO Maker vetting to a 15-minute review on a no-name launchpad
- Oversubscription dilution: Highly sought IDOs with 100-500× oversubscription result in minimal allocations worth less than the gas fees to participate

Glossary
- IDO (Initial DEX Offering)
- A token sale conducted through a decentralised exchange or dedicated launchpad platform, with immediate DEX liquidity at TGE.
- TGE (Token Generation Event)
- The moment tokens are created and distributed — for IDOs, this coincides with the DEX listing and initial liquidity addition.
- Launchpad
- A platform facilitating structured token sales with community distribution, vetting processes, and allocation management.
- Oversubscription
- When demand for IDO allocation exceeds available supply — resulting in each participant receiving a fraction of their maximum eligible allocation.
