Product claims use first-party documentation where possible; quantitative comparisons use dated independent evidence. ## Direct answer Base and OP Mainnet share OP Stack roots, but users encounter different ecosystems, liquidity, dApp deployments and governance/operational contexts. Base was much larger by the selected DeFi TVL snapshot, yet the correct network remains task-specific. The same wallet address and similar transaction UX do not make the chains interchangeable. ## Dated quantitative evidence 2 Oct 2026: Base DeFi TVL about $6.3B vs OP Mainnet about $0.49B; activity differed materially in L2BEAT captured data. ## Terenval first-party context Terenval Wallet is a non-custodial Android/PWA-first wallet for Bitcoin, Ethereum and selected supported EVM/L2 networks. Use the article below to see where it fits and where it does not. [Open Terenval Wallet](https://wallet.terenval.com/?lang=en) · [Supported networks](https://wallet.terenval.com/info/supported-networks/) · [Security](https://wallet.terenval.com/info/security/) > **Editorial disclosure:** Shared technology stack does not imply identical economics. Metrics below are a dated snapshot from independent datasets. **Snapshot — 2 October 2026:** Base DeFi TVL roughly **$6.3–6.46B** vs OP Mainnet about **$0.49B**. L2BEAT activity at the time also showed materially higher user operations on Base. Base and OP Mainnet share OP Stack roots, but users encounter different ecosystems, liquidity, dApp deployments and governance/operational contexts. Base was much larger by the selected DeFi TVL snapshot, yet the correct network remains task-specific. The same wallet address and similar transaction UX do not make the chains interchangeable. ## Comparison at a glance | Criterion | Base | OP Mainnet | | --- | --- | --- | | DeFi TVL snapshot | ~$6.3–6.46B | ~$0.49B | | Stack family | OP Stack | OP Stack | | Gas | ETH | ETH | | Address format | EVM `0x` | EVM `0x` | | Ecosystem | Base-specific apps/liquidity plus multichain protocols | Optimism-specific apps/liquidity plus multichain protocols | ## Shared stack, separate state A common stack does not merge balances or contracts. ETH on Base and ETH on Optimism are separate chain balances. A token contract address that exists on one chain may not represent the same deployment on another. Users must verify network and token identity before transferring. ## Liquidity and app fit The large Base TVL snapshot indicates a larger aggregate DeFi footprint at that time. It should not be interpreted as “Base is better.” A user needs to check whether the target dApp is deployed on both networks and whether the exact market has enough depth. ## Fees and bridges Both networks are typically low-cost relative to Ethereum Mainnet for many tasks. Same-task, same-minute fee capture is required for a fair comparison. Also include the cost of getting assets onto the chain and, if relevant, withdrawing them later. ## Terenval workflow Terenval supports both Base and Optimism. The native tutorial should show identical wallet UX sitting on different networks: switch network, verify ETH for gas, confirm the dApp is on the selected chain, and send a small first transaction. - L2BEAT TVS/Activity: https://l2beat.com/layer2s/tvs/ and https://l2beat.com/layer2s/activity - DeFiLlama Chains: https://defillama.com/chains - L2Fees: https://l2fees.info/ - Terenval Supported Networks: https://wallet.terenval.com/info/supported-networks/ Refresh chain metrics and current OP Stack/security documentation before publication updates. ## Sources and evidence - https://l2beat.com/layer2s/tvs/ - https://l2beat.com/layer2s/activity - https://defillama.com/chains - https://l2fees.info/ - https://wallet.terenval.com/info/supported-networks/ ## Related comparisons - [Arbitrum vs Optimism: Fees, TVL, Activity and Withdrawal Model Compared](https://wallet.terenval.com/comparisons/arbitrum-vs-optimism-fees-tvl-activity-withdrawals/) - [Polygon PoS vs Base: Low-Cost EVM Networks Compared](https://wallet.terenval.com/comparisons/polygon-pos-vs-base-low-cost-evm/) - [Base vs Arbitrum for Transfers: Fees, Bridges and Withdrawal Paths](https://wallet.terenval.com/comparisons/base-vs-arbitrum-l2-defi-transfers/) - [BNB Chain vs Base: Fees, Stablecoins, DeFi and Wallet Compatibility](https://wallet.terenval.com/comparisons/bnb-chain-vs-base-fees-stablecoins-defi-wallet/) Editorial policy: https://wallet.terenval.com/editorial-policy/
