In the third quarter of 2023, Optimism continued to solidify its position as a leading Ethereum Layer 2 scaling solution, achieving record-breaking network activity while simultaneously driving down transaction costs. Despite broader market downturns, the OP mainnet demonstrated resilience through robust user growth, technological advancements, and sustained DeFi dominance. This comprehensive review explores the key developments, financial metrics, and ecosystem dynamics that defined Optimism’s performance in Q3 2023.
What Is Optimism?
Optimism is an Ethereum Layer 2 scaling protocol built on optimistic rollup technology. Its primary goal is to enhance Ethereum’s transaction throughput and reduce gas fees without compromising security. By batching transactions off-chain and submitting compressed data to Ethereum’s mainnet, Optimism enables faster and more affordable interactions while inheriting Ethereum’s robust security model.
When users transact on Optimism, their signed transactions are first processed by a sequencer—a centralized component currently operated by the Optimism Foundation. Every two seconds, a new batch of executed transactions is created and periodically submitted to Ethereum as calldata. This design significantly reduces on-chain congestion and associated costs.
Crucially, all ETH-denominated revenue generated by the sequencer has been reinvested into the retroactive public goods funding initiative—a core part of Optimism’s vision for sustainable, community-driven growth. The long-term roadmap includes full sequencer decentralization, where multiple entities can participate in transaction ordering and earn a share of fees.
Optimism’s strategic vision extends beyond a single chain. The Superchain initiative, powered by the open-source OP Stack, aims to create a unified network of interoperable blockchains. Projects like Base, opBNB, Public Goods Network, and Zora are already leveraging the OP Stack, signaling growing momentum toward a modular, scalable blockchain ecosystem.

Key Metrics: Record Usage Amid Market Downturn
While the broader cryptocurrency market saw a 5.8% decline in Q3 2023—with Bitcoin and Ethereum dropping 7.5% and 10.0% respectively—Optimism defied the trend with strong fundamental growth.
Daily Active Addresses Surge to All-Time High
In Q3, Optimism achieved a record 96,000 daily active addresses, marking a 38% increase from the previous quarter and the seventh consecutive quarter of growth. This sustained upward trajectory highlights growing adoption and user retention.
Daily new addresses remained stable at around 17,000, contributing to a total of 1.5 million new users added during the quarter. The majority of this activity was driven by decentralized finance (DeFi) applications, reinforcing Optimism’s role as a preferred environment for DeFi innovation.
Transaction Volume Reaches New Peak
Daily transaction volume on the OP mainnet hit a historic high of 500,000 transactions, reflecting increased user engagement and application usage. This surge coincided with the Bedrock upgrade, which improved system efficiency and reduced costs.
Financial Performance: Lower Fees, Strong Profitability
Despite declining revenue, Optimism maintained healthy profitability thanks to reduced operational costs.
Network Revenue and Costs
- Network income (from transaction fees) decreased by 33%, from $12.5 million to $8.4 million.
- The primary driver was a 45% drop in average transaction fees, which fell from $0.51 to **$0.28 per transaction**.
- This reduction was enabled by the Bedrock upgrade’s advanced batch compression techniques and L2 support for EIP-1559, making transactions more predictable and affordable.
At the same time, Layer 1 submission costs—fees paid to post data on Ethereum—dropped by 43%, from $9.7 million to $5.5 million. This cost efficiency directly boosted profitability.
Chain-Level Profitability
After deducting L1 costs from network income, Optimism generated $2.8 million in on-chain profit** during Q3. This brings the **cumulative on-chain profit** since mainnet launch to **$15 million (or 8,600 ETH)—a key indicator of long-term economic sustainability.
Market Position and Token Performance
Despite unfavorable market conditions, OP, Optimism’s native token, showed relative strength.
- Circulating market cap grew 3.4% to $860 million by quarter-end.
- Fully diluted valuation (FDV) also rose by 3.4%, reaching $5.7 billion.
- Optimism ranked 40th among all crypto protocols by market capitalization, maintaining its status among the top-tier ecosystems.
This outperformance underscores investor confidence in Optimism’s technology, governance model, and long-term vision.
Ecosystem Overview: DeFi Dominance and Emerging Sectors
Optimism remains heavily DeFi-centric, but other verticals show potential for future expansion.
Total Value Locked (TVL)
OP mainnet’s TVL stood at $750 million at the end of Q3, placing it 6th across all networks. Although this represented a 20% quarterly decline—consistent with broader market trends—it reflects a maturing ecosystem rather than weakening fundamentals.
Top protocols by TVL:
- Synthetix: $150M (19.9%)
- Velodrome: $147M (19.5%)
- Aave: $120M (15.8%)
Notably, Aave’s TVL dropped 90% from its peak of $1.3B over the past year, likely due to shifting liquidity strategies and competition.
The “Other” category—representing non-top-10 protocols—held $143.2M in TVL (19%), though it declined by 28.6%, indicating consolidation within the DeFi space.
DeFi Diversity Index
Optimism’s DeFi diversity index reached 16 in Q3—indicating that 90% of TVL is spread across 16 protocols. A higher number suggests better risk distribution and reduced reliance on any single platform, enhancing ecosystem resilience.

DEX Trading Volume
Average daily DEX volume on Optimism was $37 million, down 12% from the previous quarter due to macro conditions like the post-USDC-unlock correction.
Top DEXs by volume:
- Uniswap: 55%
- Velodrome: 16%
- Curve & KyberSwap: 5% each
- Others: 16%
Despite the dip, Optimism ranked 6th globally in DEX volume, highlighting its importance in decentralized trading infrastructure.
Stablecoin Adoption
Stablecoin market cap on Optimism reached $568 million, ranking 8th among chains.
- USDC: $258M (45%)
- USDT: $182M (32%), up 77% quarter-over-quarter
The significant growth in USDT suggests increasing demand for alternative stablecoins on the network.
Industry Distribution: Beyond DeFi
While DeFi dominates with 83% of active consumer-facing activity, other sectors are gaining traction:
- NFTs: 12%
- Gaming & Social: Minor share
This imbalance indicates substantial untapped potential in non-financial applications. As developer tools mature and user experience improves, gaming and social platforms may drive the next wave of adoption.
FAQ: Common Questions About Optimism Q3 Performance
Q: Why did transaction fees drop so significantly in Q3?
A: The 45% reduction in average fees—from $0.51 to $0.28—was primarily due to the Bedrock upgrade, which introduced advanced batch compression and L2 support for EIP-1559, improving data efficiency and cost predictability.
Q: How does Optimism generate profit?
A: Profit is calculated as network income (gas fees) minus L1 data submission costs. In Q3, despite lower revenue, reduced submission costs led to $2.8M in on-chain profit.
Q: What is the Superchain?
A: The Superchain is a network of chains built using the OP Stack, designed for seamless interoperability, shared security, and unified governance. It represents Optimism’s long-term vision for a modular blockchain ecosystem.
Q: Why did TVL decline even as usage grew?
A: TVL often lags behind user activity due to market volatility and shifting liquidity incentives. The decline aligns with broader crypto trends but doesn’t negate strong usage fundamentals.
Q: Is Optimism still centralized?
A: While the sequencer is currently operated by the Optimism Foundation, plans for decentralization are underway. Future upgrades will allow permissionless participation and fee-sharing among sequencers.
Q: How does Optimism support public goods?
A: All sequencer revenue is directed toward retroactive public goods funding—a mechanism that rewards contributors who build valuable infrastructure for the community.
Final Thoughts: A Network Built for Long-Term Success
Optimism’s Q3 2023 performance illustrates a rare combination: growing usage, falling costs, and positive profitability—all achieved during a bear market. With record daily active addresses, efficient transaction processing, and a thriving DeFi ecosystem, Optimism continues to lead in Ethereum scaling innovation.
However, competition is intensifying. Networks like Arbitrum, zkSync, and emerging modular chains are adopting similar strategies, pushing innovation at breakneck speed.
