LAUNCHPAD DEVELOPMENT

Build a token launchpad where project quality controls protect investors and platform reputation simultaneously.

PROPELOO engineers token launchpad platforms — IDO/IEO mechanics, tiered allocation systems, KYC/whitelist management, vesting contract deployment, token distribution, refund mechanics for failed raises, and the curation infrastructure that keeps low-quality projects off the platform. A launchpad with no quality controls becomes a rug-pull distribution mechanism.

A launchpad is only as valuable as its curation. The platform reputation depends on the quality of projects it lists — and the quality of project listing depends on the controls the platform enforces.

Token launchpads facilitate primary token distribution — investors commit capital to receive tokens at a fixed price before they list on secondary markets. The platform sits between project teams and investors, and its reputation is determined by the outcome of the projects it launches. A launchpad that lists projects without due diligence will eventually list a rug pull, losing investor trust and platform credibility. PROPELOO designs launchpad platforms with quality controls as architectural concerns: tiered participation based on platform token staking (aligning investor and platform incentives), on-chain vesting contracts that cannot be modified by the project team after sale, KYC that satisfies regulatory requirements for securities-adjacent products, and refund mechanics that return capital automatically if soft cap is not reached. The smart contract architecture is designed to protect investors from team misbehaviour.

What a production token launchpad contains.

Project listing, investor allocation, sale mechanics, and distribution are each distinct systems.

System Layers

  • Project Curation Layer: Project application, due diligence workflow, listing approval, project page, tokenomics review
  • Tier & Allocation System: Platform token staking for tier assignment, guaranteed vs lottery allocation, allocation calculation
  • Sale Mechanics: FCFS, lottery, commit-and-win, whitelist, KYC gate, contribution processing
  • Vesting & Distribution Layer: On-chain vesting contract, cliff and linear vesting, TGE unlock, distribution claim interface
  • Secondary & Analytics: Post-launch trading integration, project performance tracking, investor portfolio, platform metrics

Core Technical Capabilities

  • Tier-Based Allocation

    Investors stake the platform native token to qualify for higher tiers. Each tier has guaranteed allocation (no lottery), allocation multiplier, and early access. Tier thresholds configurable. Staking lock-up period aligns investor and platform incentives.

  • Sale Mechanics

    FCFS (first-come-first-served), lottery allocation, commit-and-win (stake USDC for weighted ticket), whitelist. Soft cap and hard cap enforcement. Automatic refund on soft cap failure via smart contract.

  • KYC/Whitelist

    Sumsub KYC integration for investor verification. Jurisdiction screening (US investor restrictions for unregistered securities). Wallet whitelist for verified addresses only. KYC status sync to on-chain whitelist.

  • On-Chain Vesting Contracts

    Project-specific vesting contract deployed at TGE. Team tokens, investor tokens, and advisor tokens on separate schedules. Cliff + linear vesting. Vesting schedule immutable after deployment — project team cannot accelerate unlock.

  • Token Distribution

    Automatic token distribution at TGE to all investors. Cliff-protected tokens claimable on schedule. Claim interface. Distribution event audit log.

  • Project Application & Review

    Multi-stage project application: team verification, tokenomics review, contract audit requirement, soft commitment to vesting schedule. Curation committee workflow with approval gates.

How we approach launchpad architecture.

The launchpad is the trust intermediary between projects and investors. Its architecture must enforce the promises it makes to both sides.

  • Vesting contracts must be irrevocable

    A vesting contract that the project team can modify, pause or override is not investor protection — it is window dressing. Vesting contracts must be deployed with no admin key capable of accelerating unlocks. The contract governs the vesting; the project team is subject to it, not in control of it.

    Axiom: IRREVOCABLE VESTING

  • Tier staking aligns investor and platform incentives

    When investors must hold and stake the platform token to access quality launches, they become holders and advocates. The platform token price is supported by demand from investors who want access. This creates a sustainable token economy — not a one-time distribution.

    Axiom: STAKING AS ALIGNMENT MECHANISM

  • Soft cap failure must trigger automatic refund

    A project that fails to raise its soft cap and retains the partially raised capital is extracting value without delivering the product. Smart contracts that automatically return investor funds on soft cap failure are a non-negotiable investor protection. Manual refund processes are a trust liability.

    Axiom: AUTOMATIC REFUND ON FAILURE

Key decisions in launchpad architecture.

These choices define investor protection, platform token utility and operational complexity.

  • FCFS vs lottery vs commit-and-win allocation?

    Impact: Tiered allocation with guaranteed top tiers and lottery for lower tiers. Commit-and-win within lottery tiers. This combination maximises fairness while rewarding platform token stakers.

    • FCFS — simplest, rewards bots and fastest transactions, disadvantages retail investors
    • Lottery — equal chance per ticket, gameable by wallet splitting
    • Commit-and-win (weighted lottery) — stake capital to earn tickets, weight by amount staked, best retail fairness
    • Guaranteed allocation by tier — no lottery for top tier holders, lottery for lower tiers
  • Platform token: staking-only vs fee-plus-staking?

    Impact: Staking for tier access plus platform fee (1-3% of raise) paid by the project. Performance fee creates misaligned incentives — the platform benefits from high IDO prices regardless of project quality.

    • Staking only — token utility is tier access, no additional fees
    • Staking + platform fee (% of raise) paid in token — additional buy pressure, project cost
    • Staking + performance fee (% of IDO return) — aligns platform with investor performance
  • Vesting: off-chain managed vs on-chain contract?

    Impact: On-chain vesting contracts are required for any platform claiming to protect investors. Off-chain vesting is only acceptable for internal project team tokens where the team trusts themselves.

    • Off-chain (platform controls distribution) — simpler, platform can modify schedule, lower trust
    • On-chain contract per project — immutable once deployed, highest investor trust, gas cost per project
  • Cross-chain: single chain vs multi-chain launchpad?

    Impact: Single L2 chain for launch (Polygon, BSC, or Base). Add cross-chain via LayerZero or Wormhole bridge for token distribution after initial traction.

    • Single chain — simpler, all investors on same network, lower gas costs on L2
    • Multi-chain — larger addressable investor base, complex token bridge mechanics, higher gas cost management

The launchpad stack.

Smart contracts for trust, platform infrastructure for operations.

  • Smart Contracts

    Stack: Solidity 0.8+, Vesting contract (OpenZeppelin), Sale contract (FCFS/lottery), Staking contract, Foundry testing

  • Compliance

    Stack: Sumsub KYC, Jurisdiction screening, On-chain whitelist, Wallet verification, AML screening

  • Platform

    Stack: Node.js / Next.js, PostgreSQL, Redis, IPFS (project materials), TheGraph (indexer)

  • UX

    Stack: React (investor portal), MetaMask / WalletConnect, Vesting dashboard, Portfolio tracker, Mobile-responsive

Launchpad security protects investors from project misbehaviour and platform from reputational damage.

A single rug pull on the platform destroys investor trust built across many successful launches.

  • Smart contract audit requirement

    All projects must submit an audit from a recognised firm before listing. PROPELOO reviews the audit report as part of the listing process. Unaudited projects are not listed.

  • Team identity verification

    Project founders verified via KYC/KYB before listing. Publicly disclosed team reduces anonymous exit risk.

  • Vesting contract immutability

    Vesting contract deployed with no upgradeability, no admin key for schedule modification. Verified on-chain before announcement.

  • Soft cap automatic refund

    If soft cap is not reached, the sale contract returns all contributions automatically. No platform admin action required. Investors can verify the refund mechanism before committing.

Token launchpad platforms we have shipped to production.

Three launchpad systems that have facilitated real token sales and project raises.

  • IDO launchpad with whitelist, FCFS, and lottery sale mechanics

    Challenge: Web3 ecosystem fund needed a launchpad platform hosting IDO sales — supporting multiple sale formats (whitelist, first-come-first-served, lottery), token vesting schedules, and a KYC-gated participation system.

    Architecture: Sale contract with configurable mechanics, KYC gate via on-chain whitelist, token vesting contract with cliff and linear schedule, project onboarding workflow, investor dashboard showing allocations and unlock schedule.

    Outcome: 28 projects launched, $14M raised, 0 sale contract exploits, average oversubscription 18x, 95% vesting contract adherence.

  • NFT collection launch platform with allowlist, Dutch auction, and reveal mechanics

    Challenge: NFT studio launching 10-15 collections per month needed a self-service launchpad — artists configure collection size, price, allowlist, sale timing, and reveal schedule without engineering support per launch.

    Architecture: ERC-721A for gas-efficient batch minting, Merkle tree allowlist (addresses stored off-chain, proof verified on-chain), Dutch auction pricing curve, reveal delayed via hash commitment, self-service creator dashboard.

    Outcome: 64 NFT collections launched, £3.2M in primary sales, 40% gas saving vs ERC-721 via ERC-721A, zero failed reveals or allowlist bypasses.

  • FCA-compliant security token offering platform for real estate assets

    Challenge: Real estate fund conducting FCA-regulated security token offerings needed a compliant platform — investor accreditation verification, subscription agreement e-signature, token allocation, and secondary market eligibility checks.

    Architecture: Onfido KYC/AML, accreditation status engine, DocuSign subscription agreement workflow, permissioned ERC-20 with transfer restrictions (only verified investors), Fireblocks custody for collected funds, investor portal.

    Outcome: 4 regulated offerings completed, £8.2M raised, 100% FCA compliance maintained, zero rejected investors who should have been accepted.

Frequently Asked Questions

How do tier allocations work?

Investors stake the platform native token to qualify for a tier. Each tier has a guaranteed allocation multiplier (e.g., 1x, 3x, 5x, 10x of a base allocation unit) and some tiers have guaranteed allocation while lower tiers enter a lottery. The more tokens staked, the higher the tier and the larger the guaranteed allocation.

What prevents a project team from dumping tokens immediately after TGE?

On-chain vesting contracts with cliff and linear release periods. The contracts are deployed before the sale begins and are verifiable on-chain. Team tokens typically have a 6-12 month cliff followed by 18-24 months of linear release. The vesting schedule is immutable after deployment.

What happens if the project fails to raise the soft cap?

The sale contract includes automatic refund logic: if the raise falls below soft cap at close time, all contributions are returnable by the investor calling the refund function. No platform admin action is required. This is testable on testnet before the sale goes live.

Can we build a launchpad on BSC/Polygon/ETH?

Yes — the smart contracts are EVM-compatible and deployable on any EVM chain. We recommend Polygon or BSC for lower gas costs that make participation accessible to smaller investors. Ethereum mainnet is appropriate for higher-value institutional raises.

How do you prevent bot front-running and gas wars during public sales?

We implement cryptographic whitelist signatures (EIP-712 / Merkle Proof verification) and transaction-per-block rate limits. Users submit commitments with pre-signed authorization vouchers issued only to verified accounts, completely eliminating mempool snipers and front-running bots.

What token sale mechanisms are supported?

We build smart contracts supporting multiple sale mechanics: First-Come-First-Served (FCFS), Fixed-Price Whitelist Sales, Dutch Auctions (descending clearing price), English Auctions, Dynamic Staking Tiers, and Pro-Rata Over-Subscription models with automatic refund calculations.

How does the launchpad handle multi-currency fundraising?

The platform accepts contributions in native chain tokens (ETH, BNB, MATIC) as well as major stablecoins (USDC, USDT). Chainlink price feeds dynamically calculate accurate real-time token exchange ratios at the moment of contribution.

Does the platform support automated liquidity pool locking post-sale?

Yes. Upon successful completion of the token generation event (TGE), our smart contract factory automatically creates the trading pair on decentralized exchanges (Uniswap, PancakeSwap), seeds the initial liquidity pool, and locks LP tokens into an on-chain escrow contract (e.g., Unicrypt standard) for an agreed lockup period.
