Staking & Unstaking

Staking locks DOHM for sDOHM shares. Rewards arrive by the index rising — your share count never changes; each share is simply worth more DOHM after every rebase.

The index​

The index is a stored, monotonically increasing accumulator. It starts at 1e8 (so at genesis, 1 sDOHM = 1 DOHM) and moves only when a rebase delivers a reward:

index′  = ⌊ index × (staked + reward) / staked ⌋
staked′ = staked + reward

Nothing else — no stake, no unstake, no transfer — ever moves the index.

Stake​

shares = ⌊ deposit × 1e8 / index ⌋

Before pricing your deposit, the contract pokes a due rebase, so you always enter at the current (post-reward) index — you cannot capture rewards accrued before you staked. There is no staking fee.

Unstake — a two-step exit​

Step 1 — Request. Your shares burn and the payout is fixed immediately:

payout = ⌊ shares × index / 1e8 ⌋

A due rebase is distributed first, so you exit at the post-reward index. You receive an unstake ticket with:

unlock_height = current_height + cooldown_blocks

From this moment your position stops earning — the payout is frozen; the cooldown pays no rewards. There is no unstake fee; the cooldown is the only exit constraint.

Step 2 — Claim. At or after unlock_height, send the ticket in a second transaction:

claimable = payout   if height ≥ unlock_height and not yet claimed
          = 0        otherwise

The full payout is released (all-or-nothing cliff) and the ticket is burned. Claiming works even while the protocol is paused.

Things to know​

  • Each unstake request creates its own ticket. Multiple requests → multiple tickets → multiple claim transactions and miner fees.
  • The ticket is a bearer asset: whoever holds it claims the DOHM. A lost ticket is a lost payout.
  • Unstaking never lowers the index. Even a full drain of the staking pool freezes the index where it was — the next staker enters at the same price.
  • Rounding: both directions floor. Staking then immediately unstaking can lose up to 1 base unit (10⁻⁸ DOHM) to rounding.
