Pools maths

APY is recalculated every 6 hours (an epoch) from the fees generated by deposits and withdrawals across pools. Each epoch, the protocol computes a reward budget and distributes it to active pools.

Inputs (per epoch)

  • Pool fees: F_i = fees generated by pool i this epoch F_total = Σ F_i (sum over all active pools)

  • Active pools: N_active = number of pools that are activated (have met the activation goal)

  • Epoch reward budget (denominated in $YIELD): R_epoch = total $YIELD to distribute this epoch (derived from protocol rules and fee model)

Inactive pools get 0 this epoch (no APR) until they activate.

Distribution (20/80 rule)

  • Equal share (20%) — baseline for every active pool:

    R_equal_per_pool = 0.20 × R_epoch / N_active

  • Activity share (80%) — proportional to each pool’s fees:

    R_activity_i = 0.80 × R_epoch × (F_i / F_total)

  • Pool i epoch rewards:

    R_i = R_equal_per_pool + R_activity_i

From rewards to APR

Let TVL_i be the current staked value in pool i. APR shown in the UI is the annualized rate implied by the current epoch’s reward pace:

epochs_per_year = 365 × 24 / 6 = 1,460
BaseAPR_i = ( Value(R_i) / TVL_i ) × epochs_per_year

Value(R_i) uses the current $YIELD reference price (e.g., TWAP) at calculation time. Displayed APR is an estimate and updates every 6 hours.

Boosted APR (with Tips)

If a pool has an active boost from Tips (SOL):

BoostedAPR_i = BaseAPR_i × (1 + Boost%)

The Boost% multiplies whatever the current base APR is.

Tips do not affect activation or lock timers—only the APR once active.

Example (simplified)

  • R_epoch = 100,000 $YIELD, N_active = 3

  • Fees this epoch: Pool A F_A=10, Pool B F_B=30, Pool C F_C=60 ⇒ F_total=100

  • Equal share: 0.20 × 100,000 / 3 = 6,666.67 $YIELD per pool

  • Activity share (80,000 $YIELD):

    • A: 80,000 × 10/100 = 8,000 → R_A = 14,666.67

    • B: 80,000 × 30/100 = 24,000 → R_B = 30,666.67

    • C: 80,000 × 60/100 = 48,000 → R_C = 54,666.67

  • Convert each R_i to APR using each pool’s TVL_i and annualize (as above).

  • If Pool B has a +10% boost, APR_B becomes BaseAPR_B × 1.10.

Edge cases & notes

  • Just activated: Rewards for a pool start next epoch after activation.

  • Zero fees this epoch: If F_total = 0, the activity share is 0; if R_epoch is fee-derived, equal share may also be 0 → APRs show 0% for that epoch.

  • TVL changes: APR reflects the current TVL at the time of calculation.

Decimals/rounding: UI rounds APR to a sensible precision (e.g., 2 decimals).
