It is related to the
SatoshiVM airdrop, which uses testnet coins to get SatoshiVM Testnet tokens (
announcement tweet).
SatoshiVM has confirmed to do an airdrop to the top 5,000 testnet users. Users can now participate in testing the bridge on the newly launched testnet. The top 5,000 testnet users will receive a SatoshiVM NFT once the alpha-mainnet goes live. These NFT holders will get SAVM airdrops on a weekly basis.
In that case, Bitcoin Core devs need to take action and reset the testnet network again.
