cBridge Review 2026: Celer's Multi-Chain Asset Bridge

cBridge is the asset bridge from Celer Network. It lets users move tokens between many blockchains and layer-2 networks, including Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, zkSync Era, Avalanche and Linea. DefiLlama has listed it since November 2021 under the Bridge category.

The homepage calls it a multi-chain, cross-layer bridge with instant transfers, the most chains, the lowest fee and zero trust. Those are the project's own claims. DefiLlama shows roughly 12 million USD in TVL, down 1.9 percent over the past week, and lists two audits.

The project's own token is CELR. The docs include a security page, and Celer says cBridge builds on Celer IM and state channel technology originally tested in gaming apps.

A bridge moves value between blockchains that cannot talk to each other directly. cBridge lets you select a token on one chain and receive the equivalent on another, so you can use it with apps on that second network.

According to public sources, cBridge is built on top of Celer IM, Celer's messaging layer, and Celer's earlier state channel technology. The docs describe a hybrid model in which security and speed tradeoffs can be chosen dynamically. A third-party comparison says validation relies on the Celer State Guardian Network, a set of validators that secures the system.

In practice, you deposit on the source chain, the network validates the transfer, and the funds are made available on the destination chain. The homepage describes this as instant, low-cost and zero trust, though users should read the security docs to understand the actual trust assumptions.

The homepage claims the lowest fee among bridges, but no fee schedule or percentage is given publicly. Treat that as marketing until you compare quotes.

The app should show the bridge fee and the amount you will receive before you confirm. You would also pay network gas on the source chain, and possibly a destination-chain cost, which varies by chain. A Google result discusses plans to make CELR the fee token, but the project does not confirm the current fee model.

DefiLlama lists two audits for cBridge, but the project does not name the auditors or findings. The docs include a security page, and a third-party article says security relies on the Celer State Guardian Network. That means users rely on both smart contracts and a validator set.

All bridges concentrate funds in contracts and have historically been a frequent target for exploits. The project does not describe any incident for cBridge, and they do not rule one out. Check the docs and recent news before moving larger amounts, and consider splitting transfers.

cBridge is for DeFi users who regularly move stablecoins or other tokens across Ethereum, layer-2s and sidechains, and want one interface covering many routes. It is less suited to anyone who is uncomfortable with bridge and validator trust assumptions.
