# ERC404s in Jutsu World

### $JUTSU Features

The $JUTSU token is implemented using the standard ERC404 specification but has significant improvements in several areas (See [Improved Features](#advanced-features-of-usdjutsu) below).

### Basic Features of $JUTSU:

* **Each $JUTSU collection represents a number of Trading Cards being the total $JUTSU rounded down to the nearest whole number - i.e.** 1 $JUTSU token represents 1 Trading Card, 20.5 $JUTSU token represents 20 Trading Card.
* **Bulk and Fractional Transfers or Sale/Purchases** (Similar to ERC20 tokens**) -** $JUTSU tokens can be bought, sold, or transferred in fractions and in bulk. Trades can occur via a DEX against a liquidity pool, and transfers can occur between wallets.
* **Singular Transfers or Sale/Purchases** (Similar to ERC721 tokens/NFTs**) -** $JUTSU assets can be bought, sold, or transferred on NFT marketplaces via auction or otherwise. $JUTSU assets can be transferred via the platform.
* **Re-rolling of NFTs.** By buying or selling $JUTSU tokens against a liquidity pool NFTs can be minted or re-rolled. NFTs are typically minted for every 1 $JUTSU token purchased or re-purchased. Refer to the [Card Minting Criteria](/usdjutsu-token/card-minting-burning.md) for more information.

Example illustrating $JUTSU Basic Features

{% hint style="info" %}
*Example*

Say <mark style="color:blue;">Wally</mark> has 10.5 $JUTSU in his wallet. This would mean that he has 10 Trading Cards in his wallet.

<mark style="color:blue;">Wally</mark> decides to transfer 2.5 $JUTSU to <mark style="color:red;">Sandy</mark>, leaving him with 8 $JUTSU. This means that Wally should only have 8 Trading Cards in his wallet, and 2 Trading Cards are burnt.

<mark style="color:red;">Sandy</mark> would then have 2.5 $JUTSU in her wallet. Since <mark style="color:red;">Sandy's</mark> wallet balance moves from 0 to 2.5 $JUTSU, 2 Trading Cards would be minted in her wallet.

*Note: If Wally has a bag of 10.5 $JUTSU and transfers or sells 2.5 $JUTSU, which of the 10 Trading Cards does he lose?* [*See here for more in-depth information on Trading Card Burning/Minting*](/usdjutsu-token/card-minting-burning.md)*.*

### Advanced Features of $JUTSU:

* **Asset Locks - O**ur ERC404 implementation allows you to lock assets. Locked assets are protected and will not burn when buying/selling/transferring $JUTSU.
* **Direct Re-Roll/Re-Mints** - The traditional ERC404 implementation requires the user to commence Re-Rolls/Re-Mints by using the mechanism above. This means that the user will effectively have to trade against a Liquidity Pool for Re-Rolls/Re-Mints - resulting in the user absorbing potential slippage and transactional fees. Our ERC404 implementation allows the user to Re-Roll/Re-Mint via the ERC404 contract directly without interfacing with a third party.
* **Indirect Re-Roll/Re-Mints -** The traditional ERC404 implementation requires the user to commence Re-Rolls/Re-Mints by using the mechanism above. This mechanism is still allowed in our implementation of the ERC404 specification. However, a minimum of 0.5 $JUTSU is required.
* **Differentiated Re-rolls -** Re-rolls and purchases done via an LP or any other medium outside of <https://jutsu.world> will be all common cards. This ensures the thrill of discovering new cards is consistent in experience and that all players start from an even playing ground.

For clarity, $JUTSU can be used for DeFi and in-game purposes, but not at the same time. All holders will need to decide between DeFi participation or in-game participation.
