Sorry for my late reply. We have taken a look at the implications of running a node especially when it comes to things like security and constant upkeep.
We figured that if we are going to become a validator, we better make sure we do it properly and ensure it is secure, redundant and constantly online.
Considering that we are building a wallet platform and have a focus to make it great, we believe we should instead focus on that rather than splitting our attention on running a validator. We know that doing it properly would require a lot of focus being diverted away from our key goals where we can make the most value to the community.
For these reasons, we will not run a validator node but we still support what you are doing and I am sure we will cross paths again someday soon, especially as we are building a powerful framework that will make dapps (including the bridge and CDP portal) easy to use and rich in functionality, see TokenScript.
Keep in touch and sorry for the inconvenience caused by this.
