An Overview of the Token Standards on TomoChain
In this guide, we take a look at different token standards on the TomoChain platform.
In every blockchain ecosystem the token functions as the central element of a new type of economy. A token standard defines a set of rules that governs its issuance and use.
You may be familiar with ERC (Ethereum Request for Comments), which is a technical standard used for smart contracts on the Ethereum. This terminology is the origin of TRC tokens — the equivalent of ERC on TomoChain.
There are three token standards on TomoChain so far, each with its own unique function including TRC20, TRC21, and TRC721. These token standards can be divided into two different categories: fungible and non-fungible tokens. Fungible tokens are all equal and divisible, non-fungible tokens (NFTs) are all distinct and non-divisible.
Non-fungible tokens of the type TRC721 are those that represent a unique asset, like a certificate or a collectible in-game item. Fungible tokens are interchangeable and can be divided into smaller token units like TOMO. The fungible token standard includes TRC20 and TRC21 as digital assets used to offer access to products and/or services on a platform. The table below compares the differences between three types of token standards on TomoChain.
| TRC721 | TRC21 | TRC20 |
Divisibility | Non-Divisible | Divisible | Divisible |
Technical requirements for Dapp integration | Moderate | Moderate | Low |
Technical requirements for exchange listing | N/A | Moderate | Low |
Transaction Fee | In TOMO | In Transaction Token | In TOMO |
TRC20 is an equivalent token standard of ERC20 built on top of the TomoChain blockchain. TRC20 token holders would need to hold a small amount of TOMO to cover the extremely low transaction fees.
TRC20 wrapped tokens can be easily integrated into other Dapps and get listed on exchanges. More Dapps and projects on TomoChain are expected to be integrating and utilising TRC20 wrapped tokens in the future.
TRC21 creates a frictionless experience for non-crypto users by allowing token holders to pay transaction fees by the token itself without having to hold any TOMO in their wallet.

Non-fungible tokens (NFTs) are all distinct and special. Every token is rare, with unique characteristics, its own metadata and special attributes. Most of the time when people think about NFT, they refer to the successful CryptoKitties game as the standard for crypto-collectibles. However, there are many other applications for TRC721 tokens.
