Preparing for the SatoshiChain Bridge Testing

Connecting to the Sepolia Testnet and Polygon Mumbai Testnet

We would like to begin by apologizing to our community for the recent issues faced while using the Goerli Testnet for SatoshiChain Bridge testing. In response to these challenges, we have decided to abandon the Goerli Testnet in favor of the more reliable Sepolia Testnet. Additionally, we have added the Polygon Mumbai Testnet as another option for the testing phase. Our team is still on track to begin testing the SatoshiChain Bridge in mid-April, and we are excited to see the results. This article will guide you through the process of connecting to both the Sepolia Testnet and the Polygon Mumbai Testnet, obtaining test tokens, and participating in our incentivized testnet and airdrop campaign.

Switching to the Sepolia Testnet:

The Polygon Mumbai Testnet offers a second avenue to test and offers easy access to test Matic tokens and increased scalability, security, and low transaction fees. To connect to the Mumbai Testnet, configure your wallet (such as MetaMask) with the following network details:

  1. Network name: Mumbai
  2. Network URL:
  3. Chain ID: 80001

Please note that the faucet may have a limit on the number of test Matic tokens you can request per day. It is also essential to remember that these tokens have no real-world value and are meant for testing purposes only.

Incentivized Testnet and Airdrop Campaign:

As a reminder, testers are eligible for airdrops during our incentivized testnet campaign. For more details about this campaign, eligibility criteria, and potential rewards, please refer to our previous Medium article. The bridge testing phase will run from mid-April to mid-May. We encourage users to report any feedback or issues they encounter during the testing process via our Discord in the feedback section. Your input is valuable and helps us improve the project.

We extend our heartfelt apologies to our community for the issues encountered with the Goerli Testnet. Our team is committed to providing the best possible experience for our users, and we believe that the Sepolia Testnet and Polygon Mumbai Testnet will help us achieve that goal. We are eager to see how the bridge testing unfolds and appreciate your continued support.
