Back to projects Web3 & Token Launch
idOS Token Sale
idOS is the identity layer of web3, enabling portable identity for the stablecoin economy with self-custodial data storage and seamless KYC orchestration. We built and launched the token sale platform using Uniswap's CCA (Capped Contribution Auction) mechanism on Tally, allowing the community to participate in a fair and transparent token distribution. The sale offered 10,000,000 idOS tokens with a fully diluted valuation of $79.6M, successfully raising approximately $425,000 USD (193 ETH) from contributors worldwide.
Challenges and solutions
How we solved it
Smart contract security & auction mechanism
Implementing a Capped Contribution Auction requires airtight smart contract logic to ensure fair token distribution, prevent front-running, and handle edge cases in contribution caps. We integrated Uniswap's CCA framework with custom Solidity contracts, conducted thorough testing and auditing, and built a Go backend to reliably track on-chain events and auction state in real time.
Seamless token sale UX
Web3 token sales often suffer from confusing interfaces and poor wallet integration. We built a clean, intuitive Next.js + React frontend on Tally that guided users through wallet connection, contribution, and token claiming — making the process accessible to both crypto-native and first-time participants while displaying real-time auction metrics and transaction status.
