Posted on Discord under announcements:

ahead of promised schedule (next week) We announce such lock-in for premined coins:

5% - available this year (part of it might be used as airdrops in another project to spread awarness about webchain)
20% - available from start of 2019
30% - available from start of 2020
45% - available from start of 2021

meaning our share of premined WEB will be fully unlocked from 2021, but we are not planning to sell those coins according to lock in dates.

What we are going to use WEB for?

support of the project, marketing, promotion, development, bonuses for devs, etc.
Also, we just reached 200 miners on official pool, while biggest miners hashrate decreased, so it looks more spread out evenly now, although this might change any moment of course.
We are not going to tell you more about our ecosystem yet though. In less than two months you are going to receive:
- GUI wallet
- all details about the team
- part of the plan (not whole) revealed, including name of the popular crypto project supporting webchain, and details of how it will help promoting webchain
- other things that I don't feel comfortable promising because you will see them when they are here 😃
