Here are a few BTCL2 testnets/tasks that you can participate in recently. Since they are on the testnet, there is almost no cost, so you can participate if you have time.

1. Bsquared

There are currently point tasks that you can participate in.

2. Merlin Chain

The L2 promoted by the Blue Box project party currently has the most capable Layer 1 assets. The testnet has just been opened for a short period of time, but the project party previously said that the testnet itself will not have any token airdrops (I guess it does not rule out other incentives)

3. BEVM

It is a relatively early L2 project, and the ecology is gradually improving, so you can participate.

There is also one for node construction, which has a certain threshold

4. SatoshiVM

The token of this project has been launched. It quickly rose from over 10 million US dollars to 150 million US dollars, and then fell back to 30 million US dollars. It is currently controversial and the priority can be lower. The testnet is also more competitive, with more than 300,000 addresses. The official currently plans to launch 5,000 NFTs to reward testnet users. Decide whether to participate based on your own energy.
