# Transaction fee and cross-chain calls discount

YAR's target audience is DeFi, DEX, DAO, and Web3 projects that provide service in the B2C and B2B market. $YAR as a coin may be interesting for the mass market following the next 3 cases.

{% hint style="info" %}
The user can withdraw any assets from any blockchain to any including the native blockchain at any time. All assets are always backed 1-by-1 with circulation amounts.
{% endhint %}

### Blockchain-2-Blockchain transactions

#### Token transferring without external liquidity

Token without external liquidity Every time the user makes a cross-chain transaction pays a Transaction Fee in the Domestic Blockchain (TFDB[^1]), a Transaction Fee in the Target Blockchain and YARchain (TFTB[^2]), and a YAR's bridge reward that equals 3% from TFTB[^2] (YBR[^3]).

So each time before making the cross-chain transaction of the transferred token, YAR asks the user to pay TFTB[^2] and YBR[^3], and after token will be sent to the target blockchain. TFTB[^2] and YBR[^3] pay in coins of the domestic blockchain (ETH for Ethereum network, MATIC for Polygon, etc). So the user pays TFDB[^1] twice.

In the next step, the bridge takes TFTB[^2] and YBR[^3] holds TFTB[^2] for the next transaction fee-paying and sends a request to YARchain to mint YBR[^3] amount as an erc20 token, buy $YAR on the YAR DEX, and burn it.

#### Token with external liquidity

When the user sends a token with external liquidity, YAR offers to pay TFTB[^2] and YBR[^3] inside the transferred amount. In the next step, the bridge takes TFTB[^2] and YBR[^3] in transferred tokens and sends a request to YARchain to mint TFTB[^2] and YBR[^3] amount as an erc20 token, buy $YAR on the YAR DEX, and burn it. So the user pays TFDB[^1] once.

Rest assured that the current model guarantees both short and long-term liquidity of $YAR, and effectively mitigates the inflationary burden of new coins received by validators as rewards.

### Blockchain-2-YARchain transactions

Transferring coins and tokens inside the YARchain is always free for the user. The user pays only TFDB[^1].

### Blockchain-over\_the\_YAR-based\_DAPP-Blockchain transactions

YAR offers to cut cross-chain transaction fee costs to zero for DAPPs that will be deploying in YARchain.

**There are three cases:**

#### Case #1: Pay TFTB[^2] for your user

When DAPP's balance is more than 1,000 YAR, DAPP can offer the user free cross-chain transaction. In that case, DAPP pays TFTB[^2], not the user. It is a convenient way for users because they make only one transaction - sending assets to your service.

{% endhint %}

#### Case #2: YBR[^3] is free

When DAPP's balance is more than 10'000 YAR, DAPP can cut up to 50% of cross-chain costs.

#### Case #3: TFTB[^2] is free

When DAPP's balance is more than 100'000 YAR, DAPP pays nothing for cross-chain transactions. It is the biggest opportunity for to transactions cut spending for multi-chain DEX, payment services, NFT marketplaces, gaming platforms, arbitrating platforms, etc.

An increase in DAPPs will boost coins held on YARchain-based smart contracts and demand for the coin.
