Best crypto bridges in 2026

This guide compares eight widely used cross-chain bridge options in 2026: Across, Relay, deBridge, Stargate, Portal, Symbiosis, Circle CCTP, and native rollup bridges such as those for Arbitrum and OP Mainnet. They use different transfer and verification models, with differences in supported networks, fees, transfer times, and the type of asset received.

The comparison focuses on how each bridge works rather than ranking them from best to worst. If you're new to cross-chain transfers, start with our guide to what a cross-chain bridge is.

Quick answer: Crypto bridges use different models to move assets or value between blockchains. Across, Relay, and deBridge use relayers or solvers to fill cross-chain orders; Stargate uses cross-chain liquidity; Portal uses Wormhole messaging; Circle CCTP burns and mints native USDC and other supported assets; and canonical rollup bridges rely on the rollup's own settlement system. Compare the asset you receive, verification model, total cost, supported route, and transfer time rather than network count alone.

Best cross-chain bridges compared

The order below groups bridges by transfer model. It is a presentation choice, not a ranking. Figures are as of September 2026 and exclude network gas unless stated.

How do crypto bridges work?

A crypto bridge moves assets or value between blockchains that do not share the same ledger. The exact mechanism depends on the bridge.

Some bridges lock tokens on one chain and issue a wrapped representation on another. Others burn tokens on the source chain and mint native tokens on the destination chain, use liquidity providers or solvers to fill transfers, or rely on a rollup's canonical settlement system.

These models have different trust assumptions, fees, transfer times, and asset outcomes. Before using a bridge, check who verifies the transfer and whether you will receive a native, canonical, wrapped, or different token on the destination chain.

Types of crypto bridges

How we picked the best crypto bridges

We did not test these bridges ourselves. Every figure comes from official documentation or a named publication. A bridge had to meet all of these criteria:

• Status: it is live and maintained as of September 2026;
• Verification model: official documentation explains who confirms a transfer;
• Incident history: past incidents are publicly documented;
• Fees: the project publishes its fee schedule or shows fees in every quote;
• Interface: people can use it directly, or through named apps in the case of CCTP;
• Route type: it covers a kind of transfer that the other seven do not.

Across

Across is an intent-based bridge. You state what you want to receive, and a relayer delivers it on the destination chain from its own capital. The relayer is reimbursed after the transfer is verified through UMA's Optimistic Oracle.

• Coverage and speed: 24 mainnet chains and fills in about two seconds for most transfers, per the Across features page;
• Fees: no universal percentage. Quotes are route-specific and change with gas prices and pool utilization;
• TRON: Across announced USDT routes on TRON on June 23, 2026.

Trade-off: the project is in transition. A March 2026 proposal to replace Across's token-governed structure with a U.S. C-corporation passed a Snapshot vote. The token exchange portal closes on January 8, 2027, after which ACX will be deprecated. On July 17, 2026, an attacker forged Solana deposit events through a bug in Risk Labs' off-chain relayer software. The relayer filled 581 fraudulent requests with about $4.5 million of its own capital. Across states that no smart contract was exploited and no user funds were lost.

Who it's for: people who move funds often between Ethereum and Layer 2 (L2) networks.

Who it's not for: people bridging less common tokens. Across V4 supports ERC-20 tokens at the protocol level, but a relayer still has to fill the route.

Relay

Relay is an intent-based bridge. Relayers, also called solvers, fill transfers from their own capital.

• Coverage and speed: 85+ networks and a median fill time under three seconds, per Relay's chain list;
• Execution cost: a $0.02 flat fee plus estimated destination gas, per the Relay fee documentation;
• Platform fee: 0.00% for token bridging, 0.01% for stablecoin swaps, 0.06% for major swaps, and 0.15% for minor swaps;
• Verification: Relay's oracle attests to the origin deposit and the destination fill before the solver is reimbursed;
• Destination gas: on supported routes, Relay can add a small amount of the destination chain's gas token to your transfer.

Trade-off: execution depends on Relay's relayer infrastructure and on available liquidity for your route. When the token changes, decentralized exchange (DEX) fees, price impact, and solver rebalancing costs also apply.

Who it's for: people making small, frequent transfers to a chain where they hold no gas token yet.

Who it's not for: people moving large amounts who prefer settlement through canonical rollup infrastructure.

deBridge

deBridge runs the deBridge Liquidity Network (DLN). You place an order, and a solver fills it on the destination chain. DLN holds no central liquidity pool, a design the team calls 0-TVL (total value locked).

• Fees: four basis points (bps) plus a flat fee in the source chain's native token, per the deBridge fee documentation. The flat fee goes to deBridge validators. A solver margin of about four bps is separate;
• Coverage: 25+ blockchains, including Solana, TRON, and HyperEVM, per the deBridge FAQ and its supported chains list;
• Speed: small orders typically fill in seconds. Large orders can take minutes while solvers wait for more block confirmations.

Trade-off: Because DLN does not rely on a shared liquidity pool, an order still requires a solver willing to fill it. The deBridge documentation says an order that pays too little can stay unfilled.

Who it's for: people who want to change both token and chain in one order, including between Solana and Ethereum Virtual Machine (EVM) networks.

Who it's not for: people moving very small amounts, where the flat fee takes a larger share.

Stargate

Stargate moves assets between unified liquidity pools and uses LayerZero for messaging. Stargate V2 supports same-asset transfers only: USDC on Ethereum can only become USDC on another chain.

• Fee: route-dependent. Since September 1, 2026, Omnichain Fungible Token (OFT) transfers in the Stargate app carry a fee of up to two bps, capped at $250, per LayerZero's pricing update. The legacy fee schedule lists six bps for non-STG pool transfers;
• Modes: Taxi sends your transfer immediately, while Bus batches several transfers to share gas costs and can take longer;
• Ownership: the LayerZero Foundation acquired Stargate after a governance vote.

Trade-off: beyond the same-asset limit, Stargate's messages travel over LayerZero, where the security configuration determines which Decentralized Verifier Networks (DVNs) verify each route. In April 2026, KelpDAO's LayerZero bridge was exploited through compromised off-chain infrastructure that fed a single-verifier (1-of-1) DVN setup. Chainalysis reports that the attack did not target KelpDAO's or LayerZero's contracts. It was not an exploit of Stargate.

Who it's for: people moving stablecoins or ETH as the same asset.

Who it's not for: people who need a different token on the destination chain.

Portal (Wormhole)

Portal is the token bridge interface built on Wormhole, a cross-chain messaging protocol.

• Verification: 19 Guardians observe messages, and 13 of 19 signatures make a valid Verified Action Approval (VAA);
• Coverage: Wormhole lists 39 blockchains. Portal's interface may support a narrower set of routes;
• Fees and speed: Wormhole charges no protocol fee on core messaging. You pay network gas plus any relayer or execution fees on the route. Transfers take from about 20 seconds to 15 minutes;
• Incident record: in February 2022, an attacker took about 120,000 ETH, worth roughly $320 million at the time, through Wormhole's Solana-side implementation. Jump Crypto replenished the funds. 

The incident affected Wormhole's Solana-side implementation in 2022 and should be treated as historical incident context rather than a description of the current protocol architecture.

Trade-off: Token Bridge routes lock your asset on the source chain and mint a wrapped token on the destination chain. Your destination app may not accept that wrapped token. Wormhole's Native Token Transfers (NTT) use a different asset model, so check each route.

Who it's for: people moving assets between Solana or other non-EVM chains and EVM networks.

Who it's not for: people who need native USDC. CCTP covers that case.

Symbiosis

Symbiosis combines bridging and swaps in one interface. A peer-to-peer relayer network signs cross-chain operations using multi-party computation (MPC).

• Coverage: 59 networks, including Bitcoin, TON, TRON, and Solana alongside EVM chains as stated in Symbiosis API documentation;
• Verification: an MPC group of up to 15 relayers, with its actual size set by Proof of Stake (PoS) staking contracts. Two-thirds of the group can produce a valid signature, and every member of a separate Veto Group must also sign;
• Fees: route-dependent. Relayers pay gas on the destination side and deduct it from the amount you receive. The quote shows gas and cross-chain fees before you confirm.

Trade-off: some routes pass through Symbiosis's own S-chain, with sTokens as an intermediate step. If the final swap cannot execute, you may receive the transit token instead of the token you selected.

Who it's for: people whose route includes a non-EVM network such as Bitcoin, TON, or TRON.

Who it's not for: people making simple L2-to-L2 transfers.

Circle CCTP

Circle's Cross-Chain Transfer Protocol (CCTP) burns USDC on the source chain and mints native USDC on the destination chain. There is no wrapped token and no liquidity pool. CCTP is infrastructure, so you reach it through apps. Across, for example, uses CCTP as a fallback route.

• Coverage: 27 mainnet blockchains on CCTP V2. The legacy CCTP V1 remains on 11 blockchains, with deprecation beginning October 31, 2026 and full contract pause scheduled for December 1, 2026. CryptoSlate reports;
• Standard Transfer: about 13–19 minutes on most chains, or about eight seconds on chains with near-immediate finality, with no CCTP protocol fee;
• Fast Transfer: 8–20 seconds, with a fee of 0–13 bps, per Circle's fee documentation. Circle deducts the fee when USDC is minted.

Trade-off: CCTP's native burn-and-mint transfers currently cover Circle-issued assets such as USDC, EURC, and cirBTC. Circle is also a centralized issuer that can freeze USDC at specific addresses under its USDC terms.

Who it's for: people moving USDC who want the native token on arrival.

Who it's not for: people who need to bridge assets that CCTP does not currently support.

Native rollup bridges (Arbitrum, Base, OP Mainnet)

A native, or canonical, bridge is the one a rollup team operates between Ethereum and its own chain. It relies on the rollup's own proof system instead of a third-party bridge's relayers, guardians, or pools.

• Withdrawals: OP Mainnet, Arbitrum, and Base have a seven-day dispute or challenge period for standard withdrawals to Ethereum;
• Deposits: typically much faster, because they do not pass through a challenge period;
• Cost: transactions on the Ethereum side pay Ethereum gas, so cost follows Ethereum network conditions.

Trade-off: the withdrawal wait. You also still depend on the security assumptions of the rollup and its Ethereum settlement system.

Who it's for: people moving larger amounts who prefer canonical rollup infrastructure and can wait a week to withdraw.

Who it's not for: people who need funds the same day, or who move between two rollups, which usually means withdrawing to Ethereum first.

How to choose the best crypto bridge for your transfer

• Same asset or a different token? Stargate V2, CCTP, and native bridges deliver the same asset type you send, while deBridge, Relay, and Symbiosis can also change the token. 
• Which version of the asset will arrive? Native, canonical, and wrapped tokens have different contract addresses. Confirm that your destination app accepts yours.
• Who verifies the transfer? Compare the verification column in the table, then read each bridge's incident record.
• What is the total cost? Add the protocol fee, gas on both chains, and any slippage. Compare the final amount received.
• Is your wallet ready for the destination chain? It must support that network, and you need its gas token. 

Compare cross-chain swap offers on SwapSpace

A bridge moves the same asset between chains. If you want a different coin on another network, such as ETH on Ethereum to SOL on Solana, a swap through an exchange provider is a separate route. SwapSpace is a non-custodial cryptocurrency exchange aggregator that lets you compare such offers from dozens of providers. You do not need to connect your wallet to SwapSpace or bridge the asset manually.

1. 1. Choose the pair and the amount.
2. 2. Compare provider offers by rate, estimated time, and fixed or floating rate type.
3. 3. Enter the recipient address on the destination network.
4. 4. Send your coins to the deposit address shown.
5. 5. Track the swap until the funds arrive.

SwapSpace does not add its own markup to the rates shown; provider and network costs are reflected in the available offers. No registration is required, but a provider may request additional verification depending on the transaction or your jurisdiction. Each offer shows a Know Your Customer (KYC) likelihood indicator. 

Frequently asked questions

What is the best crypto bridge in 2026?

There is no single best crypto bridge for every route. Compare whether the bridge supports your source and destination chains, which asset arrives, total fees, transfer time, verification model, and failure/refund process. Across and Relay use intent-based transfers, CCTP specializes in native supported Circle assets, Portal covers many non-EVM routes, and canonical bridges connect Ethereum with their respective rollups.

Are crypto bridges safe to use?

Every bridge carries risk. Bridge hacks have taken more than $2.8 billion, almost 40% of the total value hacked in Web3, according to Chainlink, citing DefiLlama. In April 2026, attackers stole about $292 million from KelpDAO's LayerZero bridge. Audits reduce smart-contract risk but cannot remove it, so check the verification model and send a test transfer first.

How much does it cost to bridge crypto?

Costs come in layers: a protocol fee, gas on both chains, and slippage if the token changes. deBridge charges four bps plus a flat fee, Stargate charges up to two bps on OFT transfers, and CCTP Standard Transfer has no protocol fee. Always compare the final amount you will receive.

Do crypto bridges charge fees?

Yes, but the fee structure varies. A bridge transfer can include a protocol fee, source- and destination-chain gas, relayer or solver costs, and slippage when the destination token differs. Some protocols charge no explicit bridge fee but still require network or execution costs.

Do I need gas on both chains?

Not always. Some bridges or relayers can include destination gas in the transfer, while others require you to already hold the destination chain's native gas token. Check the quote and destination-gas options before confirming the transfer.

How long does a bridge transfer take?

Across fills most transfers in about two seconds, and CCTP Fast Transfer takes 8–20 seconds. CCTP Standard Transfer takes about 13–19 minutes on most chains. Standard withdrawals through the native bridges of OP Mainnet, Arbitrum, and Base take about seven days because of the challenge period.

What is the difference between a bridge and a cross-chain swap?

A bridge moves an asset from one blockchain to another, and you usually receive the same asset or a wrapped version of it. A cross-chain swap changes the asset as well, for example BTC to SOL. Some bridges combine both steps, and exchange providers also offer cross-chain swaps through a deposit address.

Do I receive native or wrapped tokens after bridging?

It depends on the route. CCTP mints native USDC. Stargate delivers the same asset you sent. Portal's Token Bridge routes mint a wrapped token with its own contract address. Before you confirm, compare the destination token's contract address with the one your destination app supports.

What happens if a bridge transfer gets stuck?

Save your transaction hash and check the bridge's official tracker or support channel. On intent-based bridges such as Across, a deposit that passes its fill deadline unfilled becomes eligible for a refund. Across says refunds are processed after the deposit expires and may take several hours.

Can I bridge Bitcoin to Ethereum or Solana?

Native BTC cannot simply be moved onto Ethereum or Solana as native Bitcoin because those networks use different ledgers. A cross-chain service may instead issue or deliver a tokenized representation of BTC, or swap native BTC for another asset on the destination chain.
