An IDO (Initial DEX Offering) is a fundraising method where a crypto project launches its token on a decentralized exchange (DEX) like Uniswap or PancakeSwap.

1. Token Listing on DEX:  

   The project provides liquidity and lists the token directly on a DEX.

2. Instant Trading:  

   Once live, users can trade the token immediately — no waiting like in ICOs.

3. Permissionless Access:  

   Anyone with a wallet can participate. No centralized control or approval is needed.

- Fast and open fundraising

- Immediate token liquidity

- Lower cost for project teams

- High volatility at launch

- Possibility of scams or rug pulls

- No strict regulation

IDO vs ICO:  

- IDO = Decentralized launch  

- ICO = Centralized, often private

Always research the project, DEX, and tokenomics before joining an IDO.
