What’s an IDO? A guide to initial DEX offerings
Jul 1, 2025・6 min read
Raising funds in the world of cryptocurrencies has evolved over the years, maturing from the early days of initial coin offerings (ICOs) to security token offerings (STOs), initial exchange offerings (IEOs), and, now, initial DEX offerings (IDOs).
Unlike traditional fundraising models, IDOs have gained traction due to their decentralized nature. They use decentralized exchanges (DEXs) to offer tokens directly to the public, increasing transparency by letting anyone see how the offering works and where the funds go. This also gives the community a chance to get involved early and help shape the project’s future.
In this guide, we’ll explain what an IDO is, how they work, and how they stack up against their predecessors. We’ll also cover their benefits and risks and how to participate in one.
What’s an IDO in crypto?
An IDO is a crypto fundraising method in which a project offers its token for public sale on a DEX. While traditional fundraising methods use centralized exchanges (CEX) or private sales, IDOs harness smart contracts and decentralized protocols to distribute tokens directly to users without intermediaries.
The main benefit? Projects avoid costly listing fees or meet other restrictive requirements, such as rigorous due diligence, minimum market capitalization thresholds, and complex legal compliance hurdles. Instead, users gain community-first access to early-stage investment opportunities, allowing anyone with a crypto wallet to participate.
IDOs are especially popular with decentralized finance (DeFi) projects that want to engage communities and conduct token sales in a decentralized, transparent manner.
How does an IDO work?
Conducting an IDO involves five key steps, each designed to facilitate the decentralized fundraising process and efficient token distribution:
1. Project development and token creation
The process starts with the team behind a crypto project developing its concept. They craft a whitepaper and roadmap, build the underlying technology, and design the tokenomics. That includes deciding upon the total supply of tokens, their utility within the project’s ecosystem, and the distribution schedule. After ironing out the details, the project mints the tokens on the designated blockchain, such as Ethereum, Binance Smart Chain, or Solana.
2. Selection of a decentralized exchange (DEX)
Next, the team selects a DEX that aligns with the project’s goals. Popular choices include PancakeSwap and Uniswap, while other platforms like Polkastarter and Binance Launchpool function as dedicated IDO launchpads.
This decision is critical, as DEXs offer varying features, community sizes, and fee structures. Picking the right one is often the deciding factor in whether an IDO is a success or a flop. The DEX handles the entire infrastructure for the token sale, including smart contracts for managing the sale, whitelisting, and token distribution.
3. Whitelisting and community participation
Whitelisting is a process many DEXs and IDOs implement, where prospective investors must meet specific criteria set by the project or exchange to participate in the fundraising token sale. Requirements might include holding a minimum amount of tokens, completing assigned tasks, or passing a know-your-customer (KYC) check.
This step is arguably the most critical. It ensures fair access to the token sale, and it helps prevent bots or bad actors from dominating the listing, helping legitimate users secure a fair distribution. It also heavily emphasizes community engagement, with the intent of building a strong base of loyal early supporters who will help the project grow and thrive over time.
4. Token listing and liquidity pool creation
After the whitelisting phase comes the IDO’s official launch. This involves listing the project’s tokens or coins on its chosen DEX and creating a liquidity pool by pairing the new token with a base currency, such as Ethereum (ETH) or USDT (USDT), to allow trading to commence.
Liquidity pools allow immediate trading by ensuring there’s enough capital available to match buy and sell orders. Without sufficient capital, even relatively small trades can cause significant price changes (price slippage) because the pool can’t absorb the order without shifting the price. Projects often lock up a portion of the liquidity to help prevent manipulation. They typically seed the liquidity pool with a mix of the newly issued tokens and some of the funds raised from the IDO.
5. Public trading begins
Once the IDO concludes and the token’s liquidity pool is live, it becomes publicly available for trade on the DEX. Investors who participated in the IDO can now sell their tokens, while those who did not can purchase them from the liquidity pool.
Various factors determine the token’s price, including supply and demand dynamics within the liquidity pool and the project’s traction in the broader crypto community.

Benefits of an IDO
IDOs are popular among crypto investors due to their advantages over both traditional and other crypto-native fundraising methods. Here are four key benefits:
Decentralization and transparency
Smart contracts govern the IDO process on decentralized platforms, meaning no single entity controls it. This reduces the risk of manipulation and enhances transparency, as all transactions are recorded on the blockchain and are publicly verifiable.
Immediate token liquidity
Unlike other fundraising models that may require extended token or coin lockups, IDOs provide instant liquidity through decentralized liquidity pools. This allows investors to trade tokens right after the sale, reducing the risk of being locked into illiquid assets. It also benefits the token by fostering a dynamic, active market right from the start.
Lower costs and accessibility
Conducting a decentralized IDO is typically less costly for projects than using centralized fundraising methods, as it bypasses intermediaries like banks or CEXs. This makes IDOs more accessible for smaller projects with limited budgets. For investors, participation is open to anyone with a crypto wallet, democratizing access to early-stage opportunities.
Fair token distribution
Mechanisms like whitelisting, tiered allocations, or capped investment amounts per participant help IDOs achieve fairer token distribution during the fundraising process. These measures aim to prevent large whales from dominating the sale, allowing smaller retail investors to participate and acquire tokens.
Challenges and risks of IDOs
While IDOs offer significant benefits, they’re not without challenges and risks. Here are four pitfalls to watch out for:
Market volatility
The crypto market is not only decentralized – it’s also notoriously volatile, and newly launched IDO tokens are no exception. Prices can fluctuate dramatically after launch, leading to potential losses for investors who buy at peak prices or fail to sell before a downturn.
Scams and rug pulls
The decentralized and unregulated nature of IDOs makes them vulnerable to scams, such as “rug pulls,” where developers abandon the project and abscond with the funds raised (or, in other words, take the money and run, essentially), leaving investors with worthless tokens. Conducting thorough due diligence is critical to avoid fraudulent projects.
Lack of regulation
Unlike the extensive regulation of traditional financial markets, IDOs operate in a largely unregulated space, increasing the risk of fraud and leaving investors with limited recourse if something goes wrong.
Whitelist and participation barriers
Whitelisting promotes fairness, but it can also exclude legitimate participants who fail to meet the project’s or the exchange’s eligibility criteria. Also, demand for popular IDOs often far exceeds supply, leading to highly competitive whitelists where only a small percentage of applicants secure access to the token sale.
IDOs vs. ICOs: What’s the difference?
IDOs and initial coin offerings (ICOs) are both popular crowdfunding methods in the crypto space, but they differ significantly in their structure and execution:
Control and regulation
ICOs are typically centralized and managed by a project team that controls the token sale process, which can lead to manipulation or mismanagement. IDOs, on the other hand, are decentralized and rely on DEXs and smart contracts, reducing the need for intermediaries and enhancing transparency.
Investor protections
ICOs often lack robust investor protections because they operate in unregulated environments with minimal oversight. While IDOs are also unregulated, they benefit from the transparency of blockchain and DEXs, which provide auditable records of transactions.
Token liquidity
ICO tokens often have lockup periods or require a separate listing process on a CEX, delaying investor liquidity. IDOs provide immediate liquidity through DEX liquidity pools, allowing investors to trade tokens as soon as the sale ends.
Fundraising amounts
ICOs have historically raised larger sums due to their broader reach and hype-driven nature. IDOs, in contrast, typically raise smaller amounts because they focus on community-driven participation and use purchase caps to promote fair distribution.
How to participate in an IDO
Participating in an IDO generally involves a four-step process:
- Research the project: Before investing any funds, thoroughly research the project. Analyze its whitepaper, team, roadmap, social media activity, community engagement, and independent reviews to assess its legitimacy. Checking an IDO crypto list on platforms like CoinMarketCap, Polkastarter, or dedicated launchpads can help identify legitimate and upcoming IDOs.
- Obtain the required cryptocurrency: Most IDOs require tokens like ETH or USDT for purchases. Make sure you acquire these and transfer them to a compatible non-custodial crypto wallet that you control.
- Connect a crypto wallet: Once your funds are in your digital wallet, connect the wallet to the DEX or IDO launchpad hosting the sale.
- Follow the IDO launchpad instructions: Each IDO process slightly differs depending on the project or DEX. Follow the specific instructions to register and participate, including whitelisting requirements, contribution limits, KYC processes, and token claims.
