NFT Fractionation

This repository includes an implementation of a nft-fractionation contract.

Introduction

You collect certain NFTs to exchange them for another certain NFT from any collection. For example: a unique sword is created in the game, but it can only be obtained by collecting all its parts (blade, hilt). This would motivate users to search for the necessary NFT parts, offer to redeem them to the holders of the parts themselves. And the user who collected all the parts and exchanged them for the same unique item can get special opportunities.

Prerequisites

• Make sure Rust is installed per the prerequisites in near-sdk-rs.
• Make sure near-cli is installed.

The source for this contract is in /src/lib.rs.

Building this contract

Run the following, and we'll build our rust project up via cargo. This will generate our WASM binaries into our res/ directory. This is the smart contract we'll be deploying onto the NEAR blockchain later.

sh ./scripts/build.sh

Using this contract

Quickest deploy

You can build and deploy this smart contract to a development account. Dev Accounts are auto-generated accounts to assist in developing and testing smart contracts. Please see the Standard deploy section for creating a more personalized account to deploy to.

sh ./scripts/dev-deploy.sh

Behind the scenes, this is creating an account and deploying a contract to it. On the console, notice a message like:

Done deploying to dev-1234567890123

In this instance, the account is dev-1234567890123. A file has been created containing a key pair to the account, located at neardev/dev-account. To make the next few steps easier, we're going to set an environment variable containing this development account id and use that when copy/pasting commands. Run this command to set the environment variable:

source ./scripts/neardev/dev-account.env

You can tell if the environment variable is set correctly if your command line prints the account name after this command:

echo $CONTRACT_NAME

The next command will initialize the contract using the new method:

near call $CONTRACT_NAME new_default_meta '{"owner_id": "'$CONTRACT_NAME'"}' --accountId $CONTRACT_NAME
