Step by step guide


Launchpad is used to distribute ERC-20 tokens of projects. ERC-20 tokens are placed in the wNFT version №0 (v.0) of the Envelop Protocol as Collateral. And they are being transferred to the smart-contract address of the Launchpad. You can create a wNFT here ( or here (

For each ERC-20 token, a different smart-contract is deployed for the Launchpad. And prices are set in native (coins) and ERC-20 tokens per unit of token sold. The price of wNFT with Collateral in ERC-20 tokens sold is defined as the price per unit multiplied by the number of tokens sold in the wNFT Collateral.

A separate web application is deployed for purchasers of the project tokens, to which the deployed launchpad smart-contract is connected. Deployment of the web application and the smart-contract customization can be done by the DAO Envelop support team or technical team of the project, which purchased the Launchpad from DAO Envelop. For purchasing and setup questions, please e-mail:

See documentation to learn how the smart contract of the Launchpad works.
