Remint Solana NFT App

Cryptocurrency & Blockchain

Prehistory: the client released a collection on a lounchpad, where he was wrongly made a metadata and confined the entire collection + did not give access to the account authority updates.

Task: Create a site where the user will be able to connect with the Solana crypto wallet click the "Remint" button after which all the old NFT will be destroyed and the new ones will be shut down. All of this must be done in the form of one transaction. The user should get exactly the same NFT as he had.

… Implementation: a site was implemented on React and a smart contract with which we were able to fulfill the assigned task. The client also had to place all the metadata on his server, which we also successfully did.

by Solana Airdroper

Cryptocurrency & Blockchain

Task: Write a script for the automatic sending of tokens and NFT to the Solana network to the address list.Implementation: A realised Python script based on Solana CLI with two operating modes:
1 .The user enters the token address name and the amount of tokens to be sent to each address in the .env configuration file, then puts a list of addresses in airdrop.txt and starts the script.2ndPRO mode: The script passes and performs sendings through the airdrop.csv file that contains 3 columns: token address, recipient address, number.Advantages of the script: Before the airdrop'a start, the script removes information about the number of recipients and the amount of SOL that will be spent on the airdrop.During the sending of tokens the script creates two success.csv and fail.csv files where it holds all the addresses and signatures of transactions of successful and unsuccessful sendings, after the end of the airdrop, this information is also removed.The script itself works with both ordinary tokens and NFT.Likewise, the script does not require RPC or proxy to work and there is no chance to capture any time-outs.PS: A script review is on my YouTube channel "Blockchain Developer"

ERC1155 Certificate for 01k Academy

Cryptocurrency & Blockchain

Task: Make non-transferable NFT certificates for academic students.Implementation: After consultation, the decision was made to implement certificates on the basis of the ERC1155 contract in the Polygon network.I made a contract taking into account all the wishes of the customer, set a WL mint so that the certificate could only be obtained by students who successfully passed the course, uploaded a service contract that allows you to easily and without interference in the code to add new addresses to Whitelist and broke a simple landing-page on which the user can connect his crypto wallet and finish NFT.The collection page was also set on Opensea.Collections on Opensea: https://opensea.io/collection/a01k-academy

Note: NFTs are untransmitted, while they can be displayed on Opensea, but when trying to buy them there will be a mistake.This is the feature of Opensea, because they do not prohibit the exhibition of non-transferable tokens for sale, but there is no sense in this.The certificate itself is 1 per wallet, and the money for the wallet is sent to the customer's wallet.There is also the possibility to add other certificates to the collection.

Solana Account Generator

Cryptocurrency & Blockchain

Task: Create a software that allows you to quickly generate an unlimited number of Solana accounts, then save the data in the table in the format: account, private key.
The work was done with Python script and Solana CLI. You do not need to use proxy and third-party libraries to generate accounts. The generating speed of 1000 accounts is 5 minutes (the timetables can be reduced when purchasing RPCs). The software is ready and is sold on my website. It is possible to improve the software under any needs of any blockchain software. Go to turn.
