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>
