# Managing your Tomoji NFT

*Here, we explore how ERC-404 works and the important considerations for managing these assets, especially when it comes to transferring tokens and retaining linked NFTs.*

### The Relationship Between $LONG Tokens and LONG NFTs

Contrary to what some might assume, there is no direct one-to-one correspondence between $LONG tokens (ERC20) and LONG NFTs (Non-Fungible Tokens). Instead, their <mark style="color:purple;">**relationship is managed under a "First In, First Out" (FIFO) mechanism orchestrated by the Tomoji smart contracts**</mark><mark style="color:purple;">.</mark> This approach dictates the outcomes for receiving and sending the NFTs.

#### **Ownership:**&#x20;

* A whole ERC20 $LONG token in your wallet = LONG NFT in your wallet
* A fraction of ERC20 $LONG token in your wallet = no ownership of LONG NFT
* A new NFT will be minted upon stacking a whole $LONG token in the wallet.

#### **Transferring:**&#x20;

* Transferring a whole ERC20 $LONG token = transferring one LONG NFT
* Transferring a fractional amount will burn the NFT,&#x20;
* A new NFT will be minted upon stacking a whole $LONG token in the wallet.

### Case Study 1: The Impact of Transferring $LONG

#### **Consider a hypothetical scenario:**

* Total $LONG supply of 4 tokens<br>
* Alice owns 2 $LONG tokens and 2 LONG NFTs labeled ID=1 and ID=2.
* Bob owns 2 $LONG tokens and 2 LONG NFTs labeled ID=3 and ID=4.
* John has zero balance.<br>
* Alice transfers 0.5 $LONG to John, which will burn her ID=1 LONG NFT (assuming ID=1 arrived in her wallet before ID=2).
* Subsequently, Bob transfers 0.5 $LONG to John. Similar to Alice's transaction, this results in the burning of his ID=3 LONG NFT (assuming ID=3 arrived before ID=4).<br>
* As a result of the above transactions, John accumulates 1 $LONG token and receives a LONG NFT.
* Due to the "First In, First Out" rule, John received an NFT labeled ID=1 because ID=1 was burned earlier than ID=2. Next, when someone stacks another whole $LONG token, they will receive an NFT labeled ID=2.

### Case Study 2: Changing your LONG NFT

#### **Want another LONG NFT to replace the one you currently have?**

1. Send 0.5 $LONG (ERC20) to another wallet that belongs to you. This will initiate a burn of your existing NFT on your initial wallet.&#x20;
2. Send 0.5 $LONG (ERC20) back to your initial wallet. A new NFT will be minted in your wallet.

### Important Reminder for NFT Reveal Events

Holders of $LONG tokens and LONG NFTs must understand that transferring any portion of their $LONG tokens could lead to the burning of their NFTs. As these events can significantly affect the value and composition of their digital assets, awareness and careful management are essential. <mark style="color:purple;">**Holders need to ensure they transfer the entire NFT rather than just the tokens if they wish to retain their pictorial representations.**</mark>
