Base sequencer revenue thrives as interoperability hurdles remain

Base generates a $50 million monthly fee surplus from its sequencer. This revenue follows Coinbase decisions to re-evaluate the north star of Base and its use of the Base token for growth. Coinbase also integrates cbETH L2 staking, which builds on its strategy to act as a bank replacement for people. This integration complements the Steakhouse x Coinbase partnership that provides a blueprint for neobanks to embed DeFi lending at scale.

The revenue surplus counters the fragmentation seen in the Optimism Superchain. While the Superchain includes successful networks like OP Mainnet and Base, these chains deviate from standard configurations of the OP Stack. This deviation impacts the rollout of features like interoperability. Optimism invites Layer-3 networks to join the Superchain by using the OP Stack and sharing sequencer revenue with the Optimism Collective.

Optimism promises access to a vast network of developers and growth campaigns for new L3 chains. Arbitrum developer Offchain Labs launched Orbits tools for L3 chains in 2023. Polygon CEO Marc Boiron expressed concerns about how L3 solutions affect Ethereum security.

Fragmentation vs concentrated staking capital

The Optimism Superchain faces competition from concentrated liquidity movements. The Coinbase cbETH L2 staking integration targets the same users looking for yield. Nexo provides up to 6% APY for ETH staking. This competes with the growing demand for liquid staking products.

The ability to stake crypto provides a passive income stream and contributes to network security. Validators earn rewards by staking their own tokens and sharing rewards with delegators. Foundations often allocate returnable grants to validators to incentivize early entry. These rewards for assets staked by foundations reach 5-8%, while delegators not affiliated with foundations receive 0.01-0.05%.

Validators act as principals in staking arrangements because they control the transaction validation service. Under ASC 606, validators must present revenue net of delegator rewards. These rewards function as consideration payable to customers because no distinct service exists in exchange for them. If a validator views delegation as a separate service, it acts as an agent and presents rewards on a net basis.

Rollup costs and the scaling reality

Scroll zkEVM manages batch proofs while other networks look at different scaling paths. The economic reality of batching stays central to L2 competition. Users move capital between chains using tools like Allbridge Next. Allbridge Next moves stablecoins and native gas tokens with low, predictable fees.

Allbridge Core connects independent liquidity pools on supported chains through a virtual stablecoin reference asset. This uses stable-swap mathematics to execute transfers without wrapping tokens. Smart contracts on every chain hold liquidity and enforce the pooling mechanism. Allbridge Classic supports both native and wrapped tokens across EVM and non-EVM blockchains, but the company plans to discontinue this deprecated product.

The cost of running a sequencer affects how much surplus a network retains. Base maintains a massive surplus even as other L2s struggle to attract liquidity without heavy incentive spend. Most general-purpose alt L1s and L2s struggle to keep users without these spends. Will the cost of batching proofs eventually erode the sequencer surplus of the top L2s?
