To participate in the Galaxy 100 protocol, you first need a digital wallet that supports the SUI chain. You can choose to create a SUI chain wallet in TP Wallet or use another Web3 wallet that supports the SUI chain. The key is to ensure that you have a usable SUI chain wallet address.

Next, please ensure that your Wallet has enough SUI tokens, worth at least 100 dollars. This is the minimum funding requirement to participate in the protocol.

Once ready, you need to copy and paste the link of the DAPP (decentralized application) into your Wallet. You can find and use this DAPP through the discovery feature within the Wallet.

Please note that the specific link or address for the DAPP should be obtained from other channels to ensure that you are using the correct link provided by the official source, in order to avoid potential security risks.

When participating in such protocols, it is advisable to fully understand their operational mechanisms and potential risks. The blockchain world is evolving rapidly, with new protocols and opportunities constantly emerging, but it also comes with risks. Before investing funds, be sure to conduct thorough research and assessment.

Remember, in the cryptocurrency space, security is always the top priority. Ensure that your Wallet is secure, handle your private keys with caution, and stay vigilant against potential scams.
