Base Bridge vs Linea Bridge: fees and routes (2026)

Both products are canonical bridges for moving assets from Ethereum to a layer 2, but they serve different destinations: Base Bridge connects to Base, while Linea Bridge connects to Linea. Base Bridge is also described as passing other data between the chains. Linea’s native bridge is focused on Ethereum-to-Linea transfers, while its page offers an aggregator route described as supporting transfers from any chain. The reviews report substantially different TVL figures: about $3.03 billion for Base Bridge and about $224.9 million for Linea Bridge. Those figures indicate reported use, not a guarantee of safety or performance. Choose based first on the chain where you need the funds, then compare the route and costs shown before confirming.

Linea has the clearer published fee statement for its native route: its homepage labels the Ethereum-to-Linea bridge as having no fees. That does not mean a transfer is cost-free, because Ethereum gas may still be charged when submitting a transaction. Linea’s aggregator, exchange transfers, and fiat purchase options may have separate charges or terms; their fees are not published in the review and should be checked in the relevant quote or checkout. Base Bridge does not publish bridge fee details. Its review notes that Ethereum gas is expected for deposits, and that Base transactions cost less than one cent, but that figure describes activity on Base rather than the bridge transfer. Compare the final transaction or provider quote before moving funds.

Neither of our reviews lists audits for its bridge entry, and neither provides public audit details. That absence is a limitation, not proof that either bridge has a vulnerability. Base’s review says the bridge’s security model, upgrade controls, and past incidents are not described publicly. Linea’s site links to a bug bounty and a security section, but the review does not identify audit reports. Both bridges involve smart-contract risk, and their reviews warn that bridged assets also depend on the relevant network. Linea’s native route is described as non-custodial, while its aggregator, exchange, and purchase options involve third parties with their own terms and counterparties. Verify the official site and review the available security information before connecting a wallet or transferring funds.

Base Bridge is a straightforward choice if your goal is to move supported assets from Ethereum to Base through the chain’s canonical route. It is included in Base’s quickstart documentation, and no bridge token is needed according to its review. Its reported TVL is higher than Linea Bridge’s, but that alone should not decide whether to use it. Linea Bridge adds alternatives around its native route: an aggregator, transfers from centralized exchanges, and a fiat on-ramp. That can make funding Linea more flexible, although those options introduce separate fees, terms, or counterparties that are not detailed in the review. Linea’s ease-of-use score is slightly higher. In practice, the destination chain and route you need matter more than that small score difference.

Choose Base Bridge when you need the canonical Ethereum-to-Base route, want a bridge documented in Base’s quickstart, and are comfortable checking fees and timing because those details are not published in the review. Its much higher reported TVL may appeal to users who weigh reported usage, but it is not a substitute for reviewing contract and network risks. Choose Linea Bridge when you are moving to Linea and value the stated no-fee native bridge, or want additional funding routes in one place. Remember that Ethereum gas may still apply to the native bridge, and third-party options can have their own costs and terms. Neither of our reviews provides withdrawal times or listed audits, so users who need either detail should seek current official information before proceeding.
