Developing your smart contract has never been easier! See a list of potential use cases below.

Explore <text>Smart</text> <text>Contract</text> Ideas

<item>Battleship is a popular strategic board game in which two players compete to sink an opponent's fleet hidden from their view on the playing field. The game is optimized for mobile devices and operates entirely on-chain. Additional setup option allows to include vouchers to demonstrate pay-less user experience.</item>

Battleship Game

<item>The idea behind this smart contract example is using the concert tickets as gNFTs! It’s a simple distribution with converting fungible tokens (gFT) to non-fungible tokens (gNFT) in time.</item>

Concert (FT to NFT transition)

<item>Implementing your initial coin offering could never be easier! This use case was recently very popular for new projects to raise money for development and other purposes.</item>

Crowdsale mechanics

<item>Build your decentralized autonomous organization and enable individuals to work together in transparent ways that transcend traditional forms of collaboration! There’s no longer a need for centralized control as DAOs do not need a central authority as decisions are made collectively via group proposals and votes.</item>

<item>Decentralized Internet (DNS) demonstrates an on-chain server-less approach to web sites and web applications hosting. It brings all the benefits of decentralization such as censorship resistance, security resilience and high transparency.</item>

Decentralized DNS

<item>A decentralized exchange (DEX), is a peer-to-peer marketplace where transactions occur directly between cryptocurrency traders.</item>

<item>This type of auction shows the advantage of speed since a sale never requires more than one bid. Create and run it using Gear Protocol!</item>

Dutch auction

<item>An extension of standard Non-Fungible Token. It proposes an additional dynamic part that can change or evolve over time based on certain conditions or user interactions.</item>

Dynamic NFT

<item>Escrow is a special program that is stored on a blockchain that can receive assets (like tokens) from one actor and, when certain conditions are met, sends them to another. This makes issuing payments upon completion of tasks, easy, secure and autonomous.</item>

Escrow

<item>Experimenting with the unique possibilities of smart contracts can also be fun. Imagine making your own game! The opportunities are endless… What are you waiting for? Try it now!</item>

Game of chance

<item>gFT (Gear Fungible Tokens), similar to ERC 20 tokens, is a standard for issuing smart contracts on the blockchain. These smart contracts can then be used to create tokenized assets that represent anything that is fungible.</item>

gFT (analogue to ERC-20)

<item>A single deployed smart contract may include any combination of fungible tokens, non-fungible tokens or other configurations. This is an example of a standard interface for smart contracts that manage multiple token types.</item>

gMT - Multiple Token (analogue to ERC-1155)

<item>gNFTs (Gear Non-Fungible Tokens), similar to ERC-721 NFTs, are not only about digital art. Instead, they can represent anything that is not fungible, but has unique properties. The gNFT standard can be used in any network within the Dotsama Ecosystem.</item>

gNFTs (analogue to ERC-721)

<item>We all know that security is always a priority. Multisignature wallets provide double security as they require one or more private keys to sign and send a transaction. To make it even more secure it has more than one owner and it's impossible to make a transaction without the permission of all owners.</item>

Multisig Wallet

<item>Connect buyers and sellers in one easy and streamlined place! Buy and sell non-fungible tokens for fungible tokens! Learn how to create your marketplace smart contract as well as React application and connect it to an NFT smart contract running in the blockchain.</item>

NFT Marketplace

<item>The idea for this smart contract is taken from The Million Dollar Homepage. In short, this is a website with the 1000 by 1000 pixels canvas where 1 pixel on it costs 1 dollar. NFT pixelboard uses the same logic where purchased pixel blocks are NFTs.</item>

NFT pixelboard

<item>Here the token assets are stored directly on-chain. Check the code example and try how it works!</item>

On-chain NFT

<item>Blockchain oracles are a combination of smart contracts and off-chain entities that connect blockchains to external systems, allowing other smart contracts to execute depending on real-world inputs and outputs.</item>

Oracle

<item>There is nothing better than classics! Very simple, yet so accurate! “Hello world!” on the Gear Network! Build your PING-PONG smart contract now.</item>

PING-PONG

<item>An extension of the standard Non-Fungible Token. It introduces an additional role (user) that grants permission to &quot;use&quot; the NFT, but it does not allow the ability to transfer it or set other users. The granted permission contains a predefined expiration time for this role.</item>

Rentable NFT (analogue to ERC-4907)

<item>Is a special NFT protocol aimed for establishing a standard NFT cross-chain infrastructure on Kusama/Polkadot ecosystems. RMRK legos can be implemented using Gear Protocol and you can find out how!</item>

RMRK NFT standard

<item>A popular hand game originating from China, usually played between two people, in which each player simultaneously forms one of three shapes with an outstretched hand. In this example a game is managed by a single smart contract and allows several players play simultaniously.</item>

Rock Paper Scissors

<item>Ever made a bank deposit? Staking is pretty much the same thing but in a blockchain world. Build your Staking contract with your own terms and conditions and run it on the Gear Network.</item>

Staking

<item>Many web services in Web2 work on a subscription basis that implies subscription auto-renewal. This dApp example represents a video-hosting service (VaraTube) that enables watching videos with a valid subscription that can be renewed automatically.</item>

Subscription management and auto-renewal

<item>Supply chains are systems for tracking and delivering goods to end customers. Leveraging blockchain technology makes this process more efficient, reliable and transparent!</item>

Supply chain

<item>Syndote is the name of a Monopoly-like decentralized game that works completely on-chain. It has no backend or any centralized components, the user interface interacts directly with the smart contract uploaded in the Gear Network.</item>

Syndote (Monopoly game)

<item>Tequila Train is a dominoes game similar to the Mexican Train game wirth several differences in rules.</item>

Tequila Train Game

<item>An example of a zero-knowledge proof application designed for Gear-powered blockchains. It offers the capability to shift resource-intensive computations away from the blockchain while ensuring their integrity.</item>
