The Subsidy Dilemma: Building Moats with Sponsor-Paid Onboarding

Growth requires subsidized onboarding. Every major L2 like Arbitrum and Optimism initially paid users to bridge assets and transact, creating the initial liquidity and activity that defines a network's early value.

Subsidies create mercenary capital. This strategy attracts fee-sensitive users who migrate to the next chain offering higher incentives, as seen in the perpetual L2 airdrop farming cycle.

The core challenge is moat-building. A protocol must transition from payer-funded growth to a fee-sustainable economy where users pay for inherent value, not just rewards.

Evidence: Avalanche's $180M liquidity mining program in 2021 drove a TVL spike to $11B, which subsequently fell over 90% as incentives tapered, proving subsidies alone are not a moat.

Subsidies are the moat. Paymaster competition moved from novel features to raw capital deployment. The winner subsidizes the most user transactions, not the smartest contract.

Protocols become treasury managers. Projects like Biconomy and Pimlico now operate as capital allocators, optimizing subsidy ROI across chains like Polygon and Base.

The dilemma is sustainability. Subsidies create user lock-in but drain treasuries. The model mirrors early Uniswap liquidity mining, trading short-term growth for long-term viability.

Evidence: Base's Onchain Summer, powered by paymasters, subsidized over 7 million user transactions, demonstrating that onboarding scales with capital, not code.

Growth Phase: Sponsor-Paid Onboarding is a user acquisition tool. Protocols like Optimism and Arbitrum used token airdrops to bootstrap liquidity and activity, paying users to form initial network habits.

Retention Phase: Protocol-Sustained Value begins when subsidies decline. The protocol must offer irreplaceable utility—like Uniswap's liquidity depth or Aave's capital efficiency—to retain users who arrived for free tokens.

Sunset Phase: Economic Sustainability is the final test. The protocol's native revenue model (e.g., fees, MEV capture) must fund operations. Failure here creates a 'subsidy cliff' where activity collapses, as seen in early DeFi yield farms.

Evidence: Layer 2s like Arbitrum and Base now focus on sequencer revenue and fee switches to transition from grant-funded growth to self-sustaining economies, proving the model.

Subsidies create mercenary capital. Users attracted by free transactions or token rewards exhibit zero loyalty. They leave the moment incentives dry up or a competitor offers a better deal. This is not user acquisition; it's renting attention.

The moat is illusory. A protocol's defensibility must derive from network effects, superior technology, or integrated tooling. Arbitrum's Nitro stack and Optimism's Superchain are technical moats. Airdrops and gas grants are marketing expenses.

Evidence: Post-airdrop TVL collapses are the market's verdict. Protocols like Jupiter on Solana and early Arbitrum dApps saw massive capital flight after initial distributions, proving that subsidized activity is ephemeral.

The real cost is misallocation. Capital spent on subsidies is capital not spent on core R&D or protocol security. This creates a technical debt spiral where the protocol must keep paying users to mask its underlying lack of product-market fit.

The subsidy is a weapon. Protocols like Arbitrum and Optimism used sponsored gas to bootstrap liquidity and users, creating a temporary but powerful user acquisition moat. This tactic forces competitors to match the subsidy or cede market share.

The moat evaporates post-subsidy. When the free gas stops, user retention depends on the underlying product quality. A chain with poor UX or high native fees sees users flee, as seen in early L2 cycles.

Sustainable moats are infrastructural. The endgame is embedding the subsidy into the protocol's core mechanics. Account abstraction standards like ERC-4337 and bundler services from Stackup or Biconomy enable native gas sponsorship as a permanent feature.

The winner owns the abstraction layer. The ultimate moat is not paying for gas, but controlling the intent-based transaction stack. Systems like UniswapX and Across Protocol abstract gas and bridging costs away from the user entirely, making the sponsor invisible.
