# Token Launchpad & Bonding Curve Development Token sale and distribution platforms built end-to-end: fair launch, vesting, bonding curves, allowlists, and anti-bot controls. Audit-ready, Hacken-audited team. Canonical: https://www.metaborong.com/services/web3/token-launchpad-development Service: web3/token-launchpad-development ## Overview Most token launches break at the contract that holds the money: a forked sale with no audit, weak anti-bot defence, and a vesting calendar that does not match the whitepaper. Token launchpad development is the smart-contract engineering practice that builds the platform a project sells and distributes its token through, from bonding-curve or fair-launch sale mechanics to the on-chain vesting calendar, engineered for third-party audit. ## What is it? Token launchpad development is a smart-contract engineering service for teams launching a token that need the sale, vesting, and distribution contracts built and audited rather than forked. It covers fair-launch, bonding-curve, and allowlist mechanics with anti-bot controls. We built Coin-it, a bonding-curve launchpad that graduates each token to a secondary DEX once the curve completes. ## What we deliver - Token sale contracts: fixed-price, fair-launch, or bonding-curve, with allowlist and per-wallet caps. - Vesting and distribution contracts mapping the cliff and unlock calendar on-chain. - Anti-bot and anti-snipe controls, rate limits, and KYC or allowlist gating. - Sale frontend, claim portal, and operator dashboard for caps, phases, and treasury. - Secondary-market graduation: liquidity bootstrap and DEX listing once the curve completes. ## Key concepts **Bonding curve**: A bonding curve is a smart-contract pricing mechanism where a token's price is a fixed mathematical function of its circulating supply. Each purchase mints tokens and moves the price up the curve; each sale burns tokens and moves it down. Launchpads use bonding curves to bootstrap liquidity without an order book. **Fair launch**: A fair launch is a token distribution where no tokens are pre-sold or pre-allocated to insiders before the public sale. Supply is released to all participants on equal terms at launch (often through a bonding curve or a capped public sale) to avoid concentrated early ownership. **Allowlist**: An allowlist (or whitelist) is the set of wallet addresses approved to join a token sale, usually gated by KYC, prior community membership, or a registration window. The launch contract checks membership before accepting a contribution, controlling who can buy and enforcing per-wallet limits. **Token generation event**: A token generation event (TGE) is the moment a project's token is created and first distributed to participants. It marks the start of the vesting calendar and circulating supply, and is typically when the sale, claim, and listing contracts go live on mainnet. **Graduation**: Graduation is the point at which a bonding-curve token migrates from the launchpad to a public DEX. Once the curve reaches a funding threshold, the accumulated liquidity is deployed to a trading pool, for example on Uniswap, and price discovery moves from the curve to the open market. ## How we work 1. **Sale & distribution spec** We pin down the sale model (fixed price, fair launch, or bonding curve) plus vesting, per-wallet caps, allowlist policy, KYC posture, and the graduation path to a DEX. Each parameter carries a stated range and a failure mode. The spec is the document an auditor reads first. 2. **Contracts & frontend** We build the sale, vesting, and distribution contracts against the spec with property-based and fork tests, alongside the sale frontend, claim portal, and operator dashboard. Anti-bot and anti-snipe controls are exercised against simulated sniping before the contracts go to audit. 3. **Audit, launch & graduation** The contract suite goes to a firm chosen with you. We respond to findings against a second-round review and run the sale from a reviewed deployment script. When a bonding-curve sale completes, we bootstrap secondary-market liquidity and migrate trading to a DEX, the path we built for Coin-it. ## Tech stack Solidity (Contracts), Foundry (Testing), OpenZeppelin (Libraries), Slither (Static Analysis), The Graph (Indexing), Next.js (Frontend), WalletConnect (Wallets), Uniswap (DEX), Tenderly (Monitoring) ## When this fits ### Fits when - You are launching a token and need the sale, vesting, and distribution contracts built for audit. - Fair-launch, bonding-curve, or allowlist mechanics need to be engineered rather than forked. - Budget covers an external audit of the launch contracts before the public sale. ### Does not fit when - You want a copy-paste fork of an existing launchpad with no security review. - The token has no vesting, caps, or distribution logic and a one-click mint is enough. - There is no tokenomics model behind the sale yet: start with tokenomics design first. ## FAQ ### What is a token launchpad? A token launchpad is the on-chain platform a project uses to sell and distribute its token. It handles the sale mechanics (fixed price, fair launch, or bonding curve) plus allowlists, per-wallet caps, vesting, and the claim flow after the sale. We build launchpads as audited smart-contract systems, not forks. ### What does it cost to build a token launchpad? Cost follows scope. The main drivers are the sale model (a fixed-price sale is simpler than a bonding curve that graduates to a DEX), whether vesting, anti-bot controls, and a claim portal are in scope, and whether the launch contracts go to external audit. We quote a fixed price after the spec phase, once the sale mechanics and audit scope are set. We do not publish a flat rate. ### What happens when the bonding curve completes? At a set funding threshold the token graduates: the liquidity accumulated on the curve is deployed to a public DEX pool, for example on Uniswap, and trading moves from the launchpad to the open market. We built this bonding-curve-to-DEX graduation for Coin-it. The threshold, the pool, and the fee tier are parameters set in the spec phase. ### How do you prevent bots and snipers in a token sale? Through contract-level controls: per-wallet and per-transaction caps, allowlist gating, and commit-reveal or batch-auction patterns where they fit the sale. We exercise these against simulated sniping before audit. No control is absolute, so we document the trade-offs and tune them to the sale model rather than promising a bot-proof launch. ### Is the launch contract audited? Yes. Launch contracts hold sale proceeds and enforce vesting, so they go to an external audit before the public sale, the same process behind the four Hacken audit rounds our smart-contract work has cleared. We respond to findings and ship fixes against a second-round review.
