What is deBridge?
deBridge is a pioneering protocol that aims to establish the "internet of liquidity" for the decentralized finance (DeFi) ecosystem. It enables the seamless, real-time transfer of assets and information across various blockchains. Unlike traditional liquidity pools, deBridge operates without bottlenecks and risks, ensuring deep liquidity, competitive spreads, and guaranteed rates for cross-chain interactions.
At its core, deBridge is an infrastructure platform and a comprehensive framework that empowers developers and projects to:
- Transfer assets and data: Facilitate the decentralized movement of arbitrary data and assets between different blockchains.
- Enable cross-chain interoperability: Foster composability and communication between smart contracts across various chains.
- Facilitate cross-chain swaps: Execute efficient and secure token swaps across different blockchain networks.
- Bridge NFTs: Enable the interoperability and transfer of NFTs across chains, preserving their unique logic.
By integrating with deBridge, projects can unlock a range of cross-chain opportunities, including building custom bridges, expanding their user base across multiple chains, and creating innovative cross-chain applications and primitives.
In essence, deBridge envisions a future where blockchain ecosystems are seamlessly interconnected, allowing assets, data, and applications to flow freely and securely across the DeFi landscape.

deBridge Protocol Structure
The deBridge protocol operates through a well-defined two-layer architecture, ensuring efficient and secure cross-chain interactions:
- Protocol Layer: This layer comprises on-chain smart contracts strategically deployed on every blockchain supported by deBridge. These smart contracts manage assets, route cross-chain transactions, validate validator signatures, and establish consensus among validators. A transaction is considered valid only when it receives the minimum required number of validator signatures. The deBridge governance oversees this layer, controlling key parameters like fees, supported chains, validator whitelists, and payout ratios.
- Infrastructure Layer: This layer consists of a network of trusted validators who operate deBridge nodes in conjunction with full nodes for each supported blockchain. These validators play a critical role in maintaining the blockchain infrastructure and signing transactions passing through deBridge smart contracts. Delegated staking and slashing mechanisms bolster protocol security and discourage validator collusion.
This dual-layer structure enables deBridge to provide a robust and decentralized platform for secure cross-chain asset transfers and interoperability. The protocol layer ensures transparency and control, while the infrastructure layer guarantees the network's integrity and resilience.
deBridge Off-chain validation
A core principle for bridging protocols is to remain operational even if some blockchains face downtime. deBridge achieves this with its unique off-chain transaction validation mechanism.
Unlike traditional approaches where validators broadcast transactions and incur gas fees, deBridge validators operate off-chain. Every cross-chain transaction receives a unique hash (Submission ID). Validators track these transactions and sign the Submission ID once it's finalized on the source chain. These signatures are stored on Arweave, a decentralized storage network.
Any user or keeper can retrieve these signatures and submit them, along with transaction parameters, to the DebridgeGate smart contract on the destination chain. The contract verifies the signatures and, if enough are valid, executes the transaction's call data, effectively delivering the message on the destination chain.
This design ensures deBridge's continuous operation, even during blockchain outages. Transactions destined for a paused chain are queued and processed automatically once the chain is back online.
Transaction Finality Requirements
Due to the probabilistic finality model prevalent in most blockchains, deBridge validators adhere to a cautious approach before validating cross-chain transactions. They wait for a predetermined number of block confirmations on the source chain to ensure transaction finality. This number is determined based on the social consensus regarding transaction finality for each supported blockchain. The specific requirements for each chain can be found in the Fees and Supported Chains section of the deBridge documentation.
Delegated Staking and Slashing
Validators play a pivotal role in securing deBridge's interoperability protocol. They not only act as infrastructure providers but also validate every cross-chain transaction. To ensure accountability, validators are subject to financial responsibility through a slashing mechanism. If a validator validates a non-existent transaction or fails to maintain infrastructure uptime, they risk losing a portion of their staked assets.
Anyone can contribute to the protocol's security by becoming a delegator and staking their assets (like ETH or USDC) with validators. Both validators and their delegators earn a share of the protocol fees, incentivizing them to uphold the network's security and infrastructure.
Operation mechanism of deBridge
deBridge functions as the "internet of liquidity" for DeFi, facilitating the seamless transfer of arbitrary messages and calldata across blockchains. This enables the creation of diverse cross-chain solutions, including deSwap, a value transfer protocol built on deBridge.
The ability to pass arbitrary data unlocks true cross-chain composability, allowing smart contracts and protocols on different blockchains to interact seamlessly. For instance, an algorithmic stablecoin protocol on Ethereum could open positions in a perpetual markets protocol on Solana or Arbitrum to maintain its peg.
deBridge empowers the development of a new generation of cross-chain protocols and applications, such as:
- Cross-chain swaps
- Multi-chain governance
- Cross-chain lending
- Cross-chain yield farming
By enabling the free flow of assets and information across chains, deBridge is fostering a more interconnected and efficient DeFi ecosystem.
