# ChainBridge UI Setup [Alfajores (CELO) - Rinkeby UI ](http://35.168.198.229/transfer) ## MetaMask Setup ### Adding the Alfajores (Celo) network 1. If you don’t have the Alfajores (Celo) network already added to your MetaMask account, you must add it as a custom RPC endpoint. If you do already have it added, skip to [Refreshing and connecting the wallet](#Refreshing-and-connecting-the-wallet). _Click on the network at the top of the MetaMask extension UI. Here you will see a list of all the networks you can connect to. At the bottom, you will find the option for `Custom RPC`. Use this._ ![](https://i.imgur.com/yFaY7TY.png) 2. Fill in all the necessary info for adding the Alfajores (Celo) network. ![](https://i.imgur.com/FtP3qvV.png) Here are the settings I have for Alfajores: ``` Network Name: Celo (Alfajores Testnet) New RPC URL: https://alfajores-forno-celo-testnet.org ChainID: 44787 Currency Symbol (Optional): CELO Block Explorer URL (Optional): https://alfajores-blockscout-celo-testnet.org ``` If everything connects correctly, you will see the following screen. ![](https://i.imgur.com/NPTtqEf.png) 3. The final step is to add `cUSD` tokens. To do this, select `Add Token` at the bottom the MetaMask UI. ![](https://i.imgur.com/x8U8tDe.png) 4. Fill in all the necessary info for adding the `cUSD` token. Here are the settings I have for cUSD: ``` Token Contract Address: 0x874069Fa1Eb16D44d622F2e0Ca25eeA172369bC1 Token Symbol: cUSD Token Decimal: 18 ``` ![](https://i.imgur.com/0FKngTG.png) ### Adding the cTST (Rinkeby) token _Since MetaMask already comes preconfigured with the Rinkeby network, we just need to add the Celo test token (cTST) to be viewable by the wallet._ We will repeat the previous processes for adding a new token (screenshots omitted for redundancy). 1. Switch to the Rinkeby Test Network 2. Select `Add Token` at the bottom the MetaMask UI. 3. Fill in all the necessary info for adding the `cUSD` token. Here are the settings I have for cTST: ``` Token Contract Address: 0xe09523d86d9b788BCcb580d061605F31FCe69F51 Token Symbol: cTST Token Decimal: 18 ``` ### Refreshing and connecting the wallet: 1. Connect Wallet ![](https://i.imgur.com/7rPHMTj.png) 2. Use Ethereum Wallet, if you have MetaMask installed ![](https://i.imgur.com/chxjfKD.png) If everything connects and is configured correctly then you should be presented with a screen resembling the following: **Home Network:** Celo - Alfajores **Destination Network:** Ethereum - Rinkeby ![](https://i.imgur.com/LlUph4T.png) #### You are now ready to conduct bridge transfers! --- ## ChainSafe Security Policy ### Reporting a Security Bug We take all security issues seriously, if you believe you have found a security issue within a ChainSafe project please notify us immediately.
