About company
Development and deployment of smart contracts
Development and deployment of smart contracts
We work with several well-known blockchains - Ethereum, BNB, Polygon. In some cases, we are ready to make a project in other networks. The number of tokens, the ability to include white lists, the price of the token, functions that allow you to pause the minting of tokens or price change functions, the profit distribution condition and other parameters are programmed in the smart contract. The details of how your smart contract will be arranged are determined by the terms of reference, which is formed by the customer. We will be ready to assist in the preparation of tasks that will be programmed in the smart contract.Additional services - contract deployment and verification. Deploy is the process of uploading a smart contract to the blockchain network. Verification is the verification of a smart contract and uploading the code to the browser with the possibility of interaction between the smart contract and the interface.
  • Smart contract ERC20 (utility tokens) from 1 249$
  • Smart contract ERC721 (NFT collection) from 1 849$
  • Smart Contract ERC1155 (NFT Collections) from 1 849$
  • Smart contracts with individual features on request
  • Options (provenance, whitelisting, distribution, etc.) from 309$

Audit of smart contracts
For each project, we recommend that you conduct a security audit with at least one of the providers of such services in order to check for vulnerabilities and errors in the source code of the smart contract.
  • Audit of smart contracts from 5390$
  • Primary audit of the smart contract "light" from 1690$
Interaction of smart contracts with interfaces
If you have a website and want to order the interaction of your smart contract with the interface, we are ready to offer you integration for connecting and configuring the necessary libraries (Ether.js). Sometimes you need to read data from a smart contract without connecting wallets. In this case, we connect Alchemy or Infura.
  • Integration and interaction with a smart contract from 959$
  • Creating a form mint tokens from 959$
  • Creation of algorithms for interaction with an interface and error handler from 959$
Creation of elements of graphic images for NFT
Images of the NFT token will be generated from the graphic elements. When creating elements for NFT, an artist, or a design studio, works. You can choose the contractor yourself, or entrust this work to our team.
  • Character Creation from 309$
  • Creation of graphic elements (layers) for NFT from 1 549$
Generation of unique images for NFT
The process of generating unique images from elements occurs algorithmically using scripts. When using image elements provided by the Customer before algorithmic generation, the layers are audited (checking the accuracy of gluing the elements together). The cost of generation depends on the number of layers, elements, rarity parameters, order.
  • Layers Audit from 309$
  • Generation of finished images from 619$
  • Generation of finished images (50 elements, 6 layers, 10000 pieces) 929$
Working with NFT metadata
At the time of image generation, basic metadata is created. Additional options when setting up metadata - specifying links to each image as an IPFS HASH, setting a name, inserting additional attributes.
  • Automatic change of NFT names with indication of their serial number from 309$
  • Manual editing 1pc. from 7$
  • Inserting individual IPFS hashes on content (images) from 619$
  • Creating a table of HASH256 files for Provenance from 619$
Loading and storing NFT files
You can store images of your NFTs locally or on a server, but there is a risk of losing access to them. To keep your files safe, we recommend uploading them to IPFS or Arweave.
  • Uploading IPFS Files from 149$
  • Upload files to Arweave on request
