MicroChains Cross-chain Bridge Tutorial

In this cross-chain tutorial, we will instruct users to swap their assets from Ethereum to Cardano and from Bitcoin to Cardano via the MicroChains V2 Beta.

MicroChians V2 beta testing is on the mainnet of MicroChains based on Ethereum. The testing portal is the “Launch App” on the official website.
For a better cross-chain experience, users need to visit the mainnet for testing.

Before testing, make sure you already got a Cardano wallet address. If not yet, get one by following this guide: https://medium.com/@MicroChains/how-to-create-a-cardano-address-with-nami-wallet-on-microchains-f260d5c1c297.

From Ethereum to Cardano

(1) Visit the cross-chain Launch App: https://microchains-dapp.pages.dev/

(2) Choose Ethereum as the source chain to “Send” and select Cardano as the target chain to “Receive”.

Supported currencies include $ETH, $USDT and $USDC. You can swap these 3 coins from Ethereum to Cardano. Here we take $ETH as an example.

The minimum amount of cross-chain is 0.05 ETH. MicroChains will charge a minimum fee of 0.01 ETH. For instance, if you send 0.05 ETH from Ethereum, you receive 0.04 CETH on Cardano (1:1 token swap for cross-chain).

(3) Enter your Cardano address after you filled out all required information.

(4) Click “Swap” and finish your signature by clicking “Sign”. All done!

Reminder: As the ETH network is often congested, so the actual arrival time of cross-chain transfer may take up to 30 mins or longer. Please be patient.

From Bitcoin to Cardano

(1) Visit the cross-chain Launch App: https://microchains-dapp.pages.dev/

(2) Choose Bitcoin as the source chain to “Send” and select Cardano as the target chain to “Receive”.

Reminder: The minimum amount of cross-chain is 0.001 BTC. MicroChains will charge a minimum fee of 0.0005 BTC. So if you send 0.001 BTC from Bitcoin, you receive 0.0005 CBTC on Cardano (1:1 token swap for cross-chain).

(3) Enter all required information for cross-chain and click “Swap”

(4) Using the OPEN_RETURN function to send BTC

For the cross-chain of BTC, it required users to transfer BTC to a designated wallet address with the special “OPEN_RETURN CODE”.

Click “Check the Custody Address” and get “OPEN_RETURN CODE”.

Then you’ll view the BTC recipient address on the next “Notice” page.

(5) Send BTC to the recipient address via wallets

Please enter the correct OPEN_RETURN CODE and finish the transfer of native assets “BTC”. Done!

Recommended wallets that support the OPEN_RETURN function: TokenPocket, Bitpie, and imtoken wallet.

Reminders:
Do not send BTC from exchange wallets, that will cause failure in minting and your sent BTC can not be retrieved.

Please read the “Notice” page carefully, and follow the step-by-step instruction to finish the transfer of native assets “BTC”.
