OP Stack accounting — sequencer revenue, RetroPGF, Superchain
Optimism is more than a single chain — it's the OP Stack underneath Base, World Chain, Mode, Zora, and a growing Superchain. We cover the settlement layer and the ecosystem that built on it.
Optimism's accounting story has two layers. The chain itself behaves like Arbitrum on most flows — same EVM, same 7-day optimistic withdrawal window, same gas-fee structure. What's different is the OP Stack ecosystem: Base, World Chain, Mode, Zora, and downstream Superchain members all settle to or coordinate with Optimism. Treasuries holding OP, RetroPGF recipients receiving distributions, builders of OP-Stack chains earning sequencer revenue — each has its own accounting requirement. Wag3s tracks the chain and the ecosystem.
What's tracked on Optimism
Native ETH transfers on L2
With Bedrock-era fee structure (L1 data fee + L2 execution fee broken out).
ERC-20 transfers
OP, USDC, USDT, SNX, VELO, AERO, and the long tail of Optimism DeFi tokens.
L1 ↔ L2 bridge events
Standard 7-day optimistic withdrawal tracking with intermediate state surface.
Sequencer revenue
Protocols receiving sequencer fee distributions (Optimism Foundation, downstream operators).
OP token allocations
Airdrops (rounds 1–6), RetroPGF distributions, foundation grants, vesting tracking.
RetroPGF distributions
For projects receiving Retroactive Public Goods Funding rounds — booked as ordinary income.
Velodrome / Aerodrome positions
ve(3,3) tokenomics, lock-and-vote flows, bribe receipts.
Superchain bridge events
OP ↔ Base ↔ Mode ↔ Zora interop transactions across the Superchain.
Common Optimism transaction patterns
- L1 → L2 deposit
- L2 → L1 withdrawal (7-day window)
- Velodrome / Aerodrome swap
- veVELO / veAERO lock
- Bribe receipt (RetroPGF or vote-incentive)
- OP token airdrop claim
- RetroPGF round distribution
- Synthetix staking / minting / burning
- Superchain bridge (OP ↔ Base, OP ↔ Zora)
- Sequencer batch fee receipt
What changes when you book Optimism
Bedrock changed the fee structure
Pre-Bedrock Optimism charged a single fee that included L1 and L2 components. Post-Bedrock (June 2023), the L1 data fee and L2 execution fee are separable. Wag3s tracks them independently — useful for treasuries that need to attribute L1 settlement cost separately from execution cost.
RetroPGF is recurring income, not a one-off airdrop
Projects receiving RetroPGF distributions across multiple rounds need that booked as ordinary income on each receipt date, with fair-value at the OP price on the distribution date. We tag RetroPGF receipts and book them accordingly.
Superchain interop complicates the audit trail
A transaction that originates on Base, crosses to Optimism, and lands on Zora needs to be reconciled across three wallets on three chains. We follow the message and reconcile the funds end-to-end.
Optimism accounting questions
How does Wag3s handle OP airdrop tax treatment?
OP airdrops are ordinary income on receipt at fair-value. We book each airdrop tranche at the OP price on the claim date. For multi-round airdrops (the Optimism six rounds, RetroPGF four rounds at time of writing), each round is a separate income event with its own basis for any later sale.
Does Wag3s track ve(3,3) lock positions?
Yes — Velodrome and Aerodrome ve-locks are tracked as illiquid positions with the lock-end date and underlying voting power. Lock fees are tracked separately, and bribes / vote incentives received are booked as ordinary income. Unlock and re-lock events are decoded.
Can we reconcile Optimism and Base in the same workspace?
Yes. Base settles to Ethereum and is part of the Superchain — it shows up in the same Wag3s workspace, with bridge events between Optimism and Base reconciled across both wallets.
