What Are Common Questions About Celer cBridge?

cBridge is a decentralized, non-custodial bridge that facilitates asset transfers across different blockchains utilizing the State Guardian Network (SGN), a Tendermint-based Proof-of-Stake blockchain. The SGN validators will verify the transactions and reach consensus on whether to execute cross-chain transfers or not. cBridge utilizes two types of bridging models, xAsset (lock-and-mint) and xLiquidity (pool-based).

cBridge currently supports over 30 different blockchains and layer 2 rollups such as Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Fantom, etc., it is EVM compatible and also has some level of support for non-EVM chains such as Flow. Over 130 tokens are supported on the cBridge network.

Transfer fees charged by Bridge stay inside the ecosystem and are paid out to liquidity providers and validators in the State Guardian Network (SGN). A weighted bonding curve used by Bridge generates verifiably lower bridging fees than most competing bridging protocols.

Yes. In order to provide economic incentives for security and honest behavior among its validators, cBridge utilizes a validation model called the State Guardian Network (SGN) which includes validators who have staked CELR tokens. Validators who act maliciously can be "slashed", thereby providing an additional layer of security for users. Each transaction is validated using a multi-signature based on proof of stake.

cBridge has processed over $14 billion in cross-blockchain transactions since it launched in July 2021, indicating a strong level of user trust and adoption.

cBridge offers full transparency for liquidity providers with explicit tracking of their liquidity, uses the total pool of liquidity to determine the cost of each transaction, and also provides a one click user experience while allowing the bridging of assets and arbitrary messaging via its Inter-chain Messaging Framework.

Yes. cBridge allows developers to integrate the ability to create bridged transactions into their applications via the cBridge SDK. Also, the Celer Inter-chain Messaging Framework allows developers to build dApps native to the inter-chain environment, with the added benefits of optimized use of liquidity and shared states across blockchains.

Yes. cBridge provides full transparency to all liquidity providers with explicit tracking of each individual's liquidity. This is different from other bridges that do not disclose how they allocate liquidity; instead, cBridge adds liquidity to the liquidity pool in a single transaction as part of the SGN blockchain state and does not hide or reallocate any liquidity position.

Is Celer cBridge Worth It?

cBridge from Celer is an established, secure cross-chain bridge that has supported the movement of $14B+ in cross-chain transactions. The decentralized design of cBridge, transparent model to manage liquidity and support for 30+ blockchains and 130+ tokens make it a solid option for cross-chain interoperability. Strengths of cBridge are based upon its model to provide security, low fees and easy-to-use developer tools such as the Inter-chain Messaging Framework.

What Additional Information Is Available for Celer cBridge?

Security Architecture

cBridge utilizes the State Guardian Network (SGN) which is a Cosmos based blockchain utilizing Proof of Stake Consensus. Validators have an incentive to act honestly due to the requirement to hold and stake CELR tokens, as well as the potential for slashing penalties if they engage in misbehavior.

Liquidity Provider Benefits

Liquid Providers (LPs) will receive their portion of transfer fees generated by transactions occurring through cBridge and will also be able to monitor the flow of liquidity into and out of their accounts in a completely transparent manner, without any unreported or unallocated funds being moved. cBridge utilizes all of the available liquidity within the pool to determine the cost associated with each transaction, and LPs will have the ability to manage and re-allocate their liquidity holdings across multiple blockchains with less complexity than before.

Inter-chain Messaging Framework

cBridge provides not only a solution for bridging assets, but also enables the use of an Inter-chain Messaging Framework allowing for generic message passing and cross-chain smart contract calls. This framework enables developers to create true cross-chain native applications that do not require developers to deploy separate versions of each application on every individual blockchain.

Strategic Partnerships

cBridge has partnered with several organizations including Xterio’s XterBSC Rollup and recently collaborated with Rubic to provide additional support for multi-chain swapping and DeFi ecosystem interoperability.

Developer Integration

The cBridge SDK and Inter-chain Messaging SDK allow developers to easily include cross-chain functionality into their applications. Due to the open source nature of these frameworks, as well as the extensibility of these frameworks, cBridge is capable of supporting emerging protocols as they become active.

Fee Distribution Model

Fees collected during transactions will remain within the cBridge ecosystem and will be distributed directly to liquid providers, state guardian network validators, and stakers. These distributions will provide liquid providers and validators/stakers with an incentive to maintain high levels of liquidity and network security, while maintaining transaction fees at a relatively low level for end-users.
