Celer cBridge Fees in 2026: Base Fee + 0–2% Protocol Fee, 5–20 Minutes

Celer cBridge — written variously as "cbridge", "c bridge", or "c-bridge" depending on where you look — is a long-running cross-chain bridge for tokens between EVM chains. Its official documentation describes a two-part fee (a base fee plus a protocol fee of 0–2%) and puts most transfers at 5–20 minutes. This guide explains what those numbers mean, where the docs leave gaps, and when cBridge is worth comparing.

TL;DR — Celer cBridge fee structure in 2026

• Bridge fee = base fee + protocol fee, according to the cBridge FAQ.
• Base fee: paid in the token you transfer; it covers the destination-chain gas for sending the tokens to you.
• Protocol fee: 0%–2% of the amount, depending on the source chain, destination chain and amount. It may be higher if your transfer unbalances a pool's liquidity.
• Source-chain gas: the transaction you sign to start the transfer, paid in the source chain's native token.
• Speed: most transfers take 5–20 minutes, per the FAQ. Transfers above a certain amount need additional time.

How cBridge actually works

Celer cBridge uses a hybrid model that combines Celer's State Guardian Network (SGN) — a proof-of-stake sidechain that watches for cross-chain transfer requests — with two execution paths: a liquidity-pool-based path (xLiquidity) for high-volume routes and a canonical mint-and-burn path (xAsset) for routes where Celer has issued a wrapped token.

For most user-facing transfers (USDC, USDT, ETH, native gas tokens between major EVM chains), cBridge uses the xLiquidity model: liquidity providers fund pools on each chain, and your transfer is matched against that liquidity. That is the path a transfer of USDT from Ethereum to BNB Chain takes, for instance. In this model the protocol fee is proportional to the transfer amount (after a bridge rate conversion), according to Celer's bridging models documentation. Per the FAQ, xLiquidity fee earnings are split 50/50 between SGN delegators and stakers and the cBridge liquidity providers.

How the protocol fee is set

The cBridge FAQ gives the protocol fee as a range of 0% to 2%. The percentage depends on the source chain, the destination chain and the amount you transfer, and the FAQ notes it may be higher if the transfer leaves a pool's liquidity imbalanced. Celer publishes no per-token or per-route rate table, so the exact percentage for your transfer only shows up in a live quote, whether you send USDC from Ethereum to Polygon or use the Ethereum to Arbitrum USDT route.

Celer's docs are not fully consistent here: the bridging-models page gives a range of 0% to 0.5%, while the FAQ says 0% to 2%. We quote the FAQ's wider range. Either way, the base fee comes on top, paid in the token you send.

Speed — what Celer's docs say

Celer's FAQ says most cross-chain transfers take 5–20 minutes to complete, and that transfers larger than a certain amount need additional time to go through. The docs give no per-route times.

If a transfer has been stuck for more than 30 minutes with the status "Waiting for SGN confirmation" or "Waiting for fund release", the FAQ asks you to wait at least two more hours before taking further action.

When cBridge is worth checking

• Mid-tier EVM chains like Avalanche, Fantom, Aurora, Boba, Astar — cBridge has wider coverage than Across, so check its quote for routes like USDC from Ethereum to Avalanche.
• You want a non-LayerZero alternative for diversification. Celer's SGN is independent infrastructure, useful if you are deliberately splitting bridge exposure.

When to look elsewhere

• Standard USDC transfers between Ethereum and major L2s. Many bridges compete on these routes; compare live quotes before defaulting to cBridge.
• Very large transfers. The FAQ says the protocol fee can be higher if your transfer unbalances a pool, and transfers above a certain amount need additional time.
• Speed is critical. With 5–20 minutes for most transfers, check the estimated time other bridges show for your route.

Common pitfalls

• Pool out of liquidity. cBridge depends on LPs; when a transfer would unbalance a pool, the protocol fee can rise and the quote can include high slippage. Always check the fee and slippage estimate before signing.
• Wrapped vs canonical tokens. For some chain pairs, cBridge uses xAsset (wrapped). Check the destination token contract before assuming it is the canonical version.
• Refund flow. If the destination side fails, you have to claim a refund manually on cBridge's UI. It works, but the UX is clunky and confuses users who don't know to look for it.

Bottom line

Celer cBridge is worth keeping on the shortlist for routes where it has liquidity, especially on chains Across does not cover. Its documented fee range is wide (a base fee plus 0–2%) and most transfers take 5–20 minutes, so the actual quote for your route matters more than any headline rate.

The only way to know whether cBridge is the right choice for your specific transfer is to compare quotes side by side. Run your route through BridgeFees.com — cBridge appears in the live comparison alongside Across, Wormhole, Allbridge, Synapse and other bridges. If it is the cheapest, you'll see it. If it isn't, you'll see what is.
