Near has also started moving, possibly because the recent privacy leader Zec completed its closed loop of privacy-enabled transactions through Near's cross-chain functionality.
Some people don't realize why this is important. The vast majority of funds that need to be anonymous reside outside the Zec chain, and they need a secure path to Zec. This is what the Near intent layer accomplishes through chain signatures.
Other privacy chains will likely also use Near intent to open their external channels. Let's continue to observe the trend.
