AnySwap currently supports cross-chain routing of assets between Ethereum and Shiden. 1. **How to cross-link BSC assets to Shiden?** * **Wallet network settings** You need to install MetaMask for the browser, and set up the BSC and Shiden main network for MetaMask. The specific setting parameters are as follows. **BSC network setup** > *Network Name: Binance Smart Chain Mainnet* > *New RPC URL: * > *(*If the wallet link is slow, you can use the alternate RPC address below*)* > Alternate *RPC URL: * > Alternate *RPC URL: * > *Chain ID: 56* > *Symbol (optional): BNB* > *Blockchain browser URL (optional):* [*https://bscscan.com*](https://bscscan.com) **Shiden network setup** > *Network name: Shiden Network* > *New RPC URL:* [*https://rpc.shiden.astar.network:8545*](https://rpc.shiden.astar.network:8545) > *Chain ID: 336* > *Symbol (optional): SDN* > *Blockchain browser URL (optional):* [*https://shiden.subscan.io/*](https://shiden.subscan.io/) ![](https://cdn-images-1.medium.com/max/1000/0*Laou52yIwQdpyxyX) Users can also add networks automatically through * **Cross-chain assets via AnySwap** ① Open the web page and enter the AnySwap cross-link bridge address: ② Click “Bridge” in the left menu; ③ Connect the Metamask wallet in the upper right corner and set it as the BSC (BNB) main network network; ④ Click the drop-down arrow at the token selection below the “From” input field, and a list of token options will appear to select the assets you want to cross the chain (take $KAC as an example); ⑤ In the “To” output bar below the network selection, select the network you want to cross the chain to, that is, Shiden ($SDN) main network network; ⑥ Enter the number of tokens that need to cross the chain at the horizontal line below the “From” input field; ⑦ Click the “Swap” button, the page jumps to the confirmation page; ![](https://cdn-images-1.medium.com/max/1000/0*W5fPGAv-P0qb7PwI) ⑧ On the confirmation page, click “Confirm” to pop up the Metamask window; In the Metamask window, click the “Confirm” button, and then the token BNB will be cross-linked to the Shiden chain. **2. How to make assets cross back from Shiden to BSC?** $KAC is still an example, $KAC from the Shiden back across the BSC, and $KAC from the BSC to the Shiden cross-chain similar steps. The difference is: ① The network of Metamask in the upper right corner needs to be configured as Shiden (SDN) main network; ② At the network selection below the “To” output column, the selected cross-link network is the BSC (BNB) main network. (At present, there will be a handling fee when the asset is transferred back to the BSC chain from Shiden. Please refer to the reminder below for specific fees) ![](https://cdn-images-1.medium.com/max/1000/0*fmMIICyrIK4kFha7) **3. How to cross-link Ethereum assets to Shiden?** ① Open the web page and enter the AnySwap cross-link bridge address: ② Click “Bridge” in the left menu; ③ Connect the Metamask wallet in the upper right corner and set it as the ETH main network; ④ Click the drop-down arrow at the token selection below the “From” input field, and a list of token options will appear to select the assets you want to cross the chain (take ETH as an example); ⑤ In the “To” output bar below the network selection, select the network you want to cross the chain to, that is, Shiden (SDN) main network network; ⑥ Enter the number of tokens that need to cross the chain at the horizontal line below the “From” input field; ⑦ Click the “Swap” button, the page jumps to the confirmation page; ![](https://cdn-images-1.medium.com/max/1000/0*gRtY4vWpLhPn-aA9) **4. How to make assets cross back from Shiden to Ethereum?** Still taking $KAC as an example, crossing $KAC from the Shiden back to the Ethereum is similar to crossing the Ethereum from the Ethereum to the Shiden. The difference is: ① The network of Metamask in the upper right corner needs to be configured as Shiden (SDN) main network; ② At the network selection below the “To” output column, the selected cross-link network is the Ethereum main network. ![](https://cdn-images-1.medium.com/max/1000/0*oAoh_Lap7V7SZKqT) *** ####
