Which Bridge Has the Lowest Fees? 10 Cheapest Crypto Bridges in 2026

There is no single "cheapest bridge" — there are different winners for different routes, amounts, and assets. Here are ten bridges worth comparing, with the conditions under which each one tends to be competitive. Where a fee structure is cited, it follows the provider’s official docs; the actual total is whatever the live quote shows.

1. Across Protocol

Wins for: Most small-to-medium transfers between major EVM chains.

Across uses an optimistic relay model: relayers front the capital and are reimbursed afterwards. For smaller transfers on a mainstream route (Ethereum ↔ Arbitrum/Optimism/Base/Polygon — say, ETH from Ethereum to Base), Across is often competitive. According to the Across fee docs, you pay an LP fee plus a relayer fee (covering destination gas, capital cost and risk), plus an optional app fee; the LP fee is zero when repayment is on the deposit chain.

2. Circle CCTP (Cross-Chain Transfer Protocol)

Wins for: USDC transfers where you can wait for Standard Transfer.

CCTP burns USDC on the source chain and mints fresh native USDC on the destination. According to Circle’s CCTP fee docs, Standard Transfers are free (Fast Transfers carry a fee), so on that path you pay network gas rather than a provider fee. The tradeoff is speed: Circle’s CCTP finality docs list about 15–19 minutes for Standard Transfers from Ethereum, and longer on some chains. In 2026, CCTP supports Ethereum, Arbitrum, Optimism, Base, Polygon, Avalanche, and a growing list of chains, which makes it the default for pairs like USDC from Ethereum to Avalanche.

3. Stargate Finance

Wins for: Large transfers where liquidity depth matters more than the headline fee.

Stargate’s unified LayerZero-powered pools are built for deep liquidity, which can matter on large transfers where AMM-based competitors may suffer more slippage. According to the Stargate fee docs, Stargate V2 sets a dynamic fee per route (sometimes a rebate), plus a LayerZero messaging fee paid in native gas on the source chain.

4. Official L2 bridges (Arbitrum, Optimism, Base, zkSync)

Wins for: Large deposits from Ethereum to an L2 when speed does not matter.

The native rollup bridges are operated by the rollup itself rather than a third-party provider, so a deposit is an ordinary Ethereum transaction and you pay Ethereum gas. For large amounts, where a percentage-based fee on a third-party bridge adds up, the official bridge can be the better choice — as long as you are okay with the deposit time. Per the docs, Arbitrum deposits arrive within roughly 15-30 minutes depending on chain congestion (Arbitrum docs), and OP Mainnet Standard Bridge deposits are usually completed within 1-3 minutes (OP docs). Withdrawals are a different story, see our L2→L1 guide.

5. Hop Protocol (no longer quoted)

Hop’s quote API stopped responding in July 2026, so BridgeFees.com no longer compares Hop. Hop used to be a backup on routes like the Ethereum to Polygon USDC route; compare the other bridges on this list instead.

6. Synapse Protocol

Wins for: Exotic routes and some non-USDC stablecoins.

Synapse supports a wider range of chains and tokens than most competitors. For routes the top 4 do not cover (some newer L2s, certain altcoin pairs), Synapse is often the only liquid option. Its docs publish no fee rate, so check a live quote.

7. LI.FI (aggregator)

Wins for: When you want the absolute best quote across 20+ bridges in one transaction.

LI.FI is itself an aggregator that routes your transfer through whatever underlying bridge is cheapest at that moment. According to the LI.FI FAQ, LI.FI charges a 0.25% service fee per transaction, plus the fees of the bridge or DEX used, gas, and an optional integrator fee. Whether the routing saves more than that fee depends on the live quote. Reasonable default for set-and-forget users.

8. Socket / Bungee

Wins for: Similar use case to LI.FI, with slightly different routing.

Socket aggregates across 15+ bridges and often picks different winners than LI.FI depending on liquidity conditions. Worth comparing both.

9. Wormhole / Portal

Wins for: Cross-ecosystem transfers (Solana ↔ Ethereum, etc.).

Wormhole connects EVM chains to non-EVM ecosystems like Solana, Sui, and Aptos. The security assumptions are heavier (19-guardian federation), but when you need to move from Ethereum to Solana, Wormhole is a common option. According to the Wormhole docs, there is no fee to publish a message (Solana excepted); you pay gas, plus a relayer fee if you use automatic redemption.

10. Allbridge

Wins for: Stablecoin transfers to smaller chains.

Allbridge Core specializes in stablecoin transfers (USDC, USDT, USDe) between EVM chains and non-EVM chains such as Tron, Solana, Sui and Stacks, according to its docs. According to the Allbridge Core docs, it charges a flat 0.1% service fee plus a relayer fee, with no LP fee and no price impact. It can cover non-EVM destinations that EVM-focused bridges do not serve.

Which one should you actually use?

Trick question: you should not commit to one bridge. The cheapest option rotates often, depending on gas prices, LP inventory, and relayer competition. Even on a single route such as bridging USDC from Ethereum to Arbitrum, the cheapest option can rotate between Across, Stargate, CCTP, and the official bridge.

The correct workflow is:

1. Open an aggregator (BridgeFees.com, LI.FI, or Socket) every time you want to bridge.
2. Compare the top 3–5 quotes.
3. Pick the cheapest one that meets your speed and safety requirements.
4. Verify the URL and sign.

A note on aggregator fees

Aggregators themselves usually charge a small spread on top of the underlying bridge. That is how they make money. BridgeFees.com in particular is free to use and displays the raw quotes from each underlying bridge — our revenue comes from ads, not from adding fees to your transfer. You can always click through to the underlying bridge directly for the exact quote we showed you.

Bottom line

For most users in 2026: start by comparing Across for small-to-medium EVM transfers, CCTP for USDC, official bridges for large L1→L2 deposits when speed does not matter, and aggregators for everything else. Always compare live — no static list beats a real-time quote. Start your comparison here.
