Mobile App Development for Crypto Launchpad (IDO/IEO)

We build mobile launchpads turnkey — from scratch to publication in App Store and Google Play. Development complies with App Store Review Guidelines (Section 4.2, 5.1). A crypto launchpad (IDO or IEO) is a platform where users participate in token sales. In the mobile app we implement: a project showcase, participation mechanism with USDT/BNB investment, tier access system, and vesting claim after TGE.

Moving IDO to a mobile app brings three key advantages: retention through push notifications (1.3–1.4x conversion increase), convenient transaction signing via WalletConnect or built-in wallet, and a unique UX with a token portfolio dashboard and participation history. We’ll assess your project and propose a solution within 1–2 days.

How Is the Tier System Structured?

Most launchpads use a tier system: the more native tokens a user holds (or the longer they are staked), the higher the tier—and the larger the IDO allocation. The tier is calculated based on balance + staking at the snapshot block. The logic resides on the smart contract side or off-chain with Merkle-proof.

// iOS — check user tier struct UserTier { let level: Int // 0–4 let name: String // Bronze / Silver / Gold / Platinum / Diamond let stakedAmount: BigDecimal let allocationMultiplier: Decimal } func getUserTier(address: EthereumAddress) async throws -> UserTier { let staked = try await stakingContract.balanceOf(account: address) return TierCalculator.calculateTier(stakedAmount: staked) } 

UI: profile screen with current tier, next tier, and amount to add. Progress bar "to next tier". Example tier table:

IDO Project Screen

The individual IDO page is the core of the launchpad. Structure:

• Header: logo, name, network, token contract
• Timer: time to start/end/claim
• Progress: raised X of Y USDT (progress bar)
• Token price, total supply, vesting schedule
• "Participate" button (only during whitelisting/sale period)
• Tabs: About / Tokenomics / Team / Whitepaper

Sale progress is real-time via TokensPurchased(buyer, amount) event or polling every 30 seconds.

How to Participate in an IDO

1. Whitelist registration. Sign a message (EIP-712) or send a transaction registerForSale(projectId).
2. Approval. After verification (manual or automatic), the user receives an allocation.
3. Approve token. The user calls approve to allow the smart contract to spend USDT/BNB.
4. Purchase. The transaction buy(amount) is sent. The user sees the estimated token amount and vesting schedule.
5. Track status. The project screen shows sale progress and time until claim start.

// Android — participate in IDO via smart contract suspend fun participateInIdo( saleContract: String, paymentToken: String, // USDT address paymentAmount: BigInteger ): String { // Step 1: approve USDT val approveTx = approveERC20(token = paymentToken, spender = saleContract, amount = paymentAmount) waitForReceipt(approveTx) // Step 2: participation val buyFunction = Function("buy", listOf(Uint256(paymentAmount)), emptyList()) return sendTransaction(to = saleContract, data = FunctionEncoder.encode(buyFunction)) } 

Why Is Vesting Important?

Vesting prevents immediate token dumping. After TGE (Token Generation Event), tokens unlock according to a schedule. The smart contract stores a vestingSchedule for each participant.

// iOS — calculate available claim func availableToClaim(beneficiary: EthereumAddress) async throws -> BigUInt { let schedule = try await vestingContract.getVestingSchedule(address: beneficiary) let elapsed = BigUInt(Date().timeIntervalSince1970) - schedule.startTime let vested = min(schedule.totalAmount, schedule.totalAmount * elapsed / schedule.duration) return vested - schedule.released } 

Claim screen: vesting progress (visual timeline), unlocked today, total locked, "Claim" button with amount.

Staking the Native Token

Staking is the foundation of the tier system. The user deposits tokens into a staking contract (stake(amount)) and receives a tier. The lock period may be fixed or flexible with a reduced multiplier.

// Android — staking with lock period data class StakingOption( val lockDays: Int, val tierMultiplier: Double, // 1.0x / 1.5x / 2.0x val earlyUnstakePenalty: Int // % fee for early withdrawal ) 

Display on unstake: penalty and days remaining in lock.

Push Notifications and Reminders

• Whitelist start for favorite projects
• Application approved/rejected
• IDO starts in 1 hour
• Participation transaction confirmed
• Token unlock via vesting (claim available)

Users subscribe to notifications for specific projects—not a broadcast to all.

What Is Included in Development

• Design mockups (Figma) and prototyping
• iOS (Swift 5.9+, SwiftUI) and Android (Kotlin, Jetpack Compose) development
• Smart contract integration (EVM, Solana)
• Backend (Node.js/Python) with GraphQL or REST API
• Staking and tier distribution system
• Vesting mechanism with custom schedules
• Push notifications (APNs/FCM)
• WalletConnect integration and store deployment
• Audit and testing (unit, UI, integration)
• Technical documentation and team training

Development Timelines

MVP launchpad: 6–8 weeks. With KYC integration, multi-chain support (EVM + Solana), referral program — 3 months.
