Smart contract development for token sale and presale
We develop custom smart contracts that enable efficient presales and public token sales.
Features
Our platform includes customizable rounds, automated distribution of tokens and raised funds, as well as integration with popular wallets and decentralized exchanges. With our technology, you will be able to attract investors transparently, conveniently, and securely.
You can create different sales stages with unique conditions: set minimum and maximum fundraising limits (soft/hard cap), implement bonus programs for early participants, and use dynamic pricing.
Tokens are instantly sent to investors after payment, and the raised funds are securely stored and transferred to the corporate wallet you specify.
We provide automatic token listing on leading DEX platforms such as Uniswap and PancakeSwap, as well as the ability to work with liquidity aggregators to expand reach and increase demand for your token.
We refine gas usage down to the last opcode and apply advanced patterns (for example, EIP-1559), reducing fees and speeding up transaction confirmation.
Built-in protections against duplicate payments, reentrancy attacks, and overflows, as well as preparation for third-party audits (Solidity SafeMath, OpenZeppelin).
A detailed Swagger-style API specification, code comments, and integration examples in JavaScript/TypeScript, plus assistance with deployment to test and production networks.

Token sale and presale smart contract FAQ
How does a presale differ from a public sale at the contract level?
A presale is a private stage with a whitelist, discounts, and limits for early investors; a public sale is open to everyone and usually runs at a higher price. We implement both stages in a single contract with separate settings for prices, limits, and timing.
Which sale mechanics does the contract support?
Soft cap and hard cap, minimum and maximum contribution per address, price tiers per stage, early participant bonuses, whitelists, and a choice between instant token delivery and claiming after the sale ends.
Can vesting be configured for purchased tokens?
Yes. We implement a cliff — a full lock period, linear or stepped unlocking, and a claim schedule. This protects the token price from mass sell-offs right after listing and is configured separately for each round.
How are investor funds protected during the sale?
If the soft cap is not reached, the contract automatically refunds contributions. Raised funds can only be withdrawn to a multisig wallet, the code goes through tests and an audit, and the contract is verified on an explorer so anyone can inspect the logic.
How long does it take to prepare a sale contract for launch?
A standard presale and sale contract with tests, deployment, and verification is ready in 1–3 weeks. Extra time may be needed for vesting integration, connecting the sale website, and multisig setup.
Which currencies can be accepted as payment for tokens?
Native network coins — ETH, BNB, MATIC — and USDT or USDC stablecoins. The token rate is fixed in the contract configuration, and if needed we connect an oracle to recalculate the price in dollar terms.
