+## Challenge
+
+During the activity on the testnet, we found that there were some issues when transferring through the designated channels, possibly caused by defects or attacks. A large number of transactions needed to wait a long time to be smoothly relayed, which has become a recognized challenge.
+
+However, this is also the meaning of the existence of the testnet. By solving these exposed issues, we can operate better in the formal environment. Therefore, we have set up challenge tasks to encourage participants to solve these problems, ensure the stability and normal operation of the channels, and obtain challenge points.
+
+Open an issue on `gon-evidence` to show you can solve the challenge!
+
+#### **C1**: Strategy of relaying your tx smoothly.
+
+Provide the most effective strategy and tool for transferring a stuck transaction package to the destination chain, ensuring seamless transaction relay between different blockchains.
+
+**Rules:**
+- Select only two best solutions
+- Explain the principle and provide the code
+
+#### **C2**: Strategy of preventing bunch txs stuck on channels.
+
+Provide the most effective strategy to ensure smooth and uncongested transfer operation between chains, preventing batches of transactions from getting stuck.
+
+**Rules:**
+- Select only one best solution
+- Explain the principle and provide the code
