What is Optimism (OP), the Ethereum Layer-2 token?

Optimism is an Ethereum Layer-2 ecosystem built on optimistic rollup technology. Its open-source OP Stack powers the Superchain, a network of 25+ interoperable chains including Base and Ink. The ecosystem is governed by the Optimism Collective, a two-house structure consisting of the Token House and the Citizens' House. OP is a governance token, not a gas token — transaction fees on Optimism are paid in ETH.

How is the OP governance token used within the Optimism Collective?

OP is a governance token. Holders vote on protocol upgrades and treasury decisions through the Token House, or delegate voting power to representatives. The second chamber, the Citizens' House, oversees Retroactive Public Goods Funding. OP carries no gas or payment function — Optimism network fees are denominated in ETH.

What is Optimism's total supply?

OP has a fixed maximum and total supply of 4,294,967,296 tokens — exactly 2^32. Per DropsTab data, allocations split as follows: Core Contributors 19%, Investors 17%, user and future airdrops roughly 19% combined, Retroactive Public Goods Funding and retrodrops roughly 20%, and ecosystem, governance, partner and seed funds about 25%. The supply cap is hard-coded, not elastic.

How does the OP vesting schedule affect investors?

Investor and Core Contributor tokens carried a one-year cliff that expired on 31 May 2023, releasing 4.25% and 4.75% of total supply respectively. Since then, monthly unlocks total roughly 32M OP — about 0.75% of supply per month, split between Investors (15.2M) and Core Contributors (17.0M). DropsTab vesting data tracks 82 scheduled unlock events. This recurring supply growth has historically pressured OP around large unlock dates.

Did Optimism have an ICO, and what is the OP ICO price?

Optimism did not hold an ICO. OP launched at TGE on 31 May 2022, and distribution ran through airdrops and governance allocations instead. No ICO price exists for OP — the token never sold in an initial coin offering. Users searching for an "OP ICO price" should treat the airdrop distribution and TGE date as the token's true launch record.

Which OP airdrops has Optimism distributed?

Optimism ran four user airdrops. Airdrop 1 on 31 May 2022 distributed 214,871,200 OP — 5.0% of total supply. Airdrop 2 on 9 February 2023 distributed 11.7M OP. Airdrop 3 on 19 September 2023 distributed 19.4M OP. Airdrop 4 on 20 February 2024 distributed 10.4M OP. A 13% "Future Airdrops" allocation remains reserved, alongside retrodrop distributions tied to RetroPGF rounds.

What was SuperStacks on Optimism?

SuperStacks was Optimism's first Superchain-wide incentive program — a live test rewarding cross-chain usage, liquidity provision and long-term contributions across OP-Stack chains. The Point Farming campaign ran from 16 April to 30 June 2025 and has ended. Participation rewarded interoperability between Superchain chains rather than activity on a single network. No equivalent campaign is currently running.

Is Base part of the Optimism Superchain?

Yes. Base is built on the OP Stack and operates as part of the Superchain — the network of 25+ interoperable chains that share Optimism's bridge and standards. Other Superchain members include Ink. This structure makes Superchain adoption a direct driver of Optimism ecosystem value and of fee revenue shared between OP Labs and member chains.

Who backed Optimism and how much did it raise?

Optimism raised more than $268M across four rounds, per DropsTab fundraising data. The Seed round brought in $3.5M from Paradigm and IDEO CoLab in December 2019, while the project operated as Plasma Group. a16z led a $25M Series A in February 2021. The $150M Series B in March 2022 valued Optimism at $1.65B and was co-led by a16z and Paradigm. In 2024, a16z purchased roughly 19.5M OP for about $90M under a two-year vesting schedule.

How is OP traded — centralized or decentralized exchanges?

Per DropsTab data, OP trades on 70+ spot pairs across 50+ centralized exchanges, with fiat quotes in USD, EUR, TRY, KRW, JPY, THB and IDR — including Binance, Coinbase, Kraken, OKX and Upbit. Derivatives run on multiple venues including Binance Futures, Hyperliquid, OKX and Kraken Futures. Tracked decentralized-exchange coverage is thin; deep on-chain OP liquidity exists but sits outside the tracked count.
