L2 Liquidity Landscape: Capital Flow from OP Stack to Base

Zoom out to a 12-month view and the distribution of stablecoins across L2s is being redrawn. The pre-2025 "OP Stack first, everyone else second" picture has cracked — Arbitrum still holds the TVL crown, but the marginal flow has tilted markedly toward Base.

Base's growth is not incentive-driven — no airdrop, no sequencer-fee rebate. It pulls capital through two channels: Coinbase's on-ramp (USDC moves on with near-zero friction) and the compounding effect of meme and social-asset liquidity on DEXs. It is a clean sample of "app layer attracts users, app layer retains capital".

For an infrastructure layer like F* Protocol the L2 spread is an engineering reality — FundVault sits on Arbitrum Sepolia today because Arbitrum is still the L2 institutions are most comfortable with, holds the largest TVL, and has the most mature bridge tooling. But "follow the user's money" forces the protocol layer to take Base deployment paths seriously.

We tracked the migration of the major stablecoins (USDC, USDT, DAI, sUSDS, USDe) across five L2s over the past six months, matched against DEX 24-hour volume. The counter-intuitive finding: cross-chain stablecoin migration does not correlate strongly with native bridge fees — the dominant driver is the CEX-to-L2 on-ramp. Coinbase's zero-fee USDC channel into Base visibly accelerated stablecoin inflow into Base.
