# How to trade on FXDX with assets on the Near

**Suppose you have $USDT in your Near account and want to buy tokens on Fxdx**

Since authorization and bridge only require a small gas fee<mark style="color:red;">**($TAO for authorization fee, $Near for  Bridge fee)**</mark>, I recommend you to exchange [gas fee($TAO, $NEAR) directly on Ref](https://app.ref.finance/#dac17f958d2ee523a2206206994597c13d831ec7.factory.bridge.near|fusotao-token.near)

## 1/Prepare some $TAO as authorization fee

Authorizing tokens to FXDX requires a small amount of $TAO as Authorize fee. There are two ways to get $TAO

* buy TAO on CEX and deposit it into the Near account: [deposit-usdtao-to-avatar-wallet](https://fusotao-protocol.gitbook.io/fusotao/avatar-wallet/deposit-usdtao-to-avatar-wallet "mention")
* Swap on Ref, there is a pool on [Ref](https://app.ref.finance/#dac17f958d2ee523a2206206994597c13d831ec7.factory.bridge.near|fusotao-token.near) for small exchange

## 2/Prepare some $Near as Bridge fee

Bridge tokens from Near network to Fusotao application chain requires a small amount of $Near as gas fee.&#x20;

&#x20;There are two ways to get $Near

* buy Near on CEX and deposit it into the Near account
* Swap on Ref

## 3/Bridge

Bridge $TAO and $USDT, from Near Network to Fusotao Chain, where $USDT is the token that will be traded on FXDX, and $TAO will be used as an authorization fee later

Then bridge $TAO from Near account to Fusotao account

you can use Octoupus Network Bridge: [bridge](https://fusotao-protocol.gitbook.io/fusotao/fusotao-mainnet/bridge "mention")
