Harbor Vault started with a group of friends in Seoul who wanted staking rewards but also needed to pay rent from the same ORL. Unstaking meant a 21-day wait, so one of them wrote a vault that stakes most of the deposits and keeps the rest ready to withdraw.
The round 5 grant paid for the vault contracts and their audit, instant withdrawals from that liquid buffer and a public page that shows reserves at every block. Harbor Vault now holds $88M in deposits.
