ORBIT DESKnon-custodial rebalancing desk
ORBIT DESKnon-custodial · bounty keeper · three walls
ORBIT DESK is a tokenized index desk. You set a mandate of target weights; prices drift; a permissionless keeper rebalances toward target and earns a proportional bounty — guarded at every step by three walls. No vault. No yield-farm. No admin withdraw.
Four verbs define the whole product. Everything else is guardrail.
The manager fixes the fund's mandate: target weights that must sum to 100%. Only the manager; never a withdraw.
Holders enter the basket with follow and exit pro-rata with cross. There is no manager redemption — only share holders.
A keeper realigns the basket toward target and earns a bounty minted as shares. The contract enforces the three walls before paying a single wei.
Every rebalance is checked against all three — or it reverts.
A rebalance must strictly reduce drift. No bounty for making the basket worse.
The keeper's price feed must track the reference oracle within a deviation band.
Bounty is proportional to drift-reduction, gated by a floor + cooldown. Splitting can't farm.
One command closes the whole circuit.
