## Contract Receiving

**1. Select Network and Connect Wallet**

Based on your business needs, visit [Smaet Contract Platform](http://cold.chainup.com)，choose the contract network you wish to access and connect your third-party wallet.

> [!TIP]

> 1. You may need to install a browser extension for the third-party wallet to invoke the wallet and access the contract on the Web.
> 2. Custody supports the following contract networks:
>    * Ethereum
>    * Binance Smart Chain
>    * TRON
>    * Huobi ECO Chain
> 3. Different network contracts support different wallets. For example, accessing TRON contracts requires connecting to TronLink or OKX.

View the contract list, select the contract you wish to access, and click to enter the \[Asset Management] page.

> [!TIP]
