Fee routing

Every enrolled token has a TokenRewardSplit — basis points that must sum to 10 000 (100%).

Split table

Creators configure the last three at launch; they must sum to 95%. PUM is always 5%.

// config.ts — default user-configurable split
DEFAULT_REWARD_SPLIT: {
  pumBps: 500,
  diemBps: 2850,
  perpBps: 5700,
  creatorBps: 950,
}

Claim cycle

The fee claimer (claimPooledFeesCycle):

1. Round-robin batch of enrolled tokens (CLAIM_BATCH_SIZE, default 25)
2. collectRewards + claim USDC from Clanker FeeLocker
3. Attribute USDC per token
4. splitProtocolUsdc on the protocol share (PUM + DIEM + perp):

pumUsdc  = usdc × (pumBps / (pumBps + diemBps + perpBps))
diemUsdc = usdc × (diemBps / …)
perpUsdc = usdc × (perpBps / …)

5. Accrue to in-memory accumulators (addTokenRewardAllocation)

Creator USDC never passes through the engine — it sits in FeeLocker for the creator to claim via Clanker.

Fission 70/30 vs pumperp

Historical Fission docs describe a simple 70% perps / 30% protocol token burn.

pumperp generalizes this:

• PUM tithe (5%) ≈ network tax on every launch (was 30% in Fission, but only of protocol flow)
• Perp slice ≈ Fission's 70% desk leg (now per-token, agent-managed)
• DIEM + creator ≈ new legs for intelligence endowment and optional creator cash

config.FEE_SPLIT (positionFund: 0.7, buyback: 0.3) is deprecated — the live path is TokenRewardSplit per token.

Validation

buildRewardSplit rejects negative bps and enforces:

diemBps + perpBps + creatorBps === 10000 - PUM_REWARD_BPS  // 9500

API accepts either raw bps in rewardSplit or whole-percent shortcuts (diemPct, perpPct, creatorPct).
