{"id":"hyperbridge","title":"Hyperbridge","content":"**Hyperbridge** is a decentralized interoperability protocol designed for secure cross-chain communication and asset transfers. It utilizes a \"coprocessor model\" with Zero-Knowledge (ZK) state proofs to verify cross-chain states, positioning itself as a trust-minimized alternative to traditional multisig-based bridges. \n\nThe protocol's infrastructure is built around the Inter-State Messaging Protocol (ISMP) and its native utility token is $BRIDGE. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa) [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n## Overview\n\nHyperbridge aims to provide a \"hyperscalable, verifiable interoperability\" layer for a modular blockchain ecosystem. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa) \n\nIts core architecture is designed to offer security guarantees comparable to the underlying Layer-1 blockchains it connects by relying on cryptographic proofs instead of a trusted set of validators. The protocol primarily serves the [Polkadot](https://iq.wiki/wiki/polkadot), [Kusama](https://iq.wiki/wiki/kusama), and [Ethereum](https://iq.wiki/wiki/ethereum) ecosystems, with integrations across various parachains and EVM-compatible networks. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa) [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\nThe project's developer stack is centered on the Interoperable State Machine Protocol (ISMP) SDK, which provides tools for building cross-chain applications in both Solidity and WASM environments. This enables developers to create applications such as cross-chain decentralized exchanges (DEXes), multi-chain lending protocols, and intent-based architectures. The protocol's founders and core team members are not publicly disclosed on its official website or social media channels. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa) [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n## Technology\n\nHyperbridge's technical architecture is founded on trust-minimization principles, using advanced cryptography to facilitate secure communication between blockchains. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n### Core Architecture and Coprocessor Model\n\nThe protocol employs an off-chain system known as a coprocessor model, which combines cryptoeconomic incentives with ZK state proofs to verify cross-chain transactions. \n\nThis model is intended to mitigate the security risks associated with Multi-Party Computation (MPC) and multisig validator sets, which rely on the honesty of a small, trusted group. By using state proofs generated directly from the source blockchain's consensus, Hyperbridge aims to inherit the security of the underlying chains it connects. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa)​\n\n### Zero-Knowledge (ZK) Light Clients\n\nA key component of Hyperbridge's system is its use of ZK-powered light clients. Instead of requiring a full node of a connected blockchain to be run on the destination chain, these light clients can efficiently verify state changes and consensus rules. \n\nPermissionless relayers submit messages and state proofs between chains, and the ZK light clients on the destination chain cryptographically verify these proofs. This process ensures the validity of cross-chain messages without relying on external, trusted parties. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n### Inter-State Messaging Protocol (ISMP)\n\nThe core messaging layer of Hyperbridge is the Inter-State Messaging Protocol (ISMP). It is a lightweight, rollup-centric protocol designed specifically for integration with ZK technologies. \n\nThe ISMP SDK is available for developers working in both EVM (via Solidity) and WASM (for [Polkadot](https://iq.wiki/wiki/polkadot) and its parachains) environments, providing the foundational tools for building cross-chain native applications. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa) [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n### Permissionless Relayer Network\n\nHyperbridge operates a permissionless relayer network where any user can run a node to transmit cross-chain messages. Relayers are incentivized by earning fees for their services. This open model does not require whitelisting or asset staking to participate, promoting a decentralized approach to message passing. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa)​\n\n### Cross-Chain Sequencer\n\nThe protocol also functions as a cross-chain sequencer, which allows for the ordering of cross-chain transactions. This capability creates a market for cross-chain Maximal Extractable Value (MEV) and enables features like priority fees, where relayers can pay to influence the sequence of transaction delivery across chains. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\n## Products and Use Cases\n\nHyperbridge provides infrastructure for both end-users and developers to engage with the multi-chain ecosystem.\n\n### Key Products\n\n* **Token Gateway:** The primary application for users, enabling them to bridge tokens and other assets between supported blockchain networks. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa)\n* **Multichain Native Tokens:** Infrastructure that allows developers to issue tokens that can exist natively across multiple blockchains, avoiding the fragmentation associated with wrapped assets. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)\n\n### Developer Use Cases\n\nThe protocol's technology is designed to support the development of various cross-chain applications, including:\n\n* Cross-chain Decentralized Exchanges (DEXes)\n* Cross-chain lending and borrowing protocols\n* Cross-chain intent-based architectures\n* Multichain Liquid Restaking Tokens (LRTs)\n* Global on/offramps for digital assets\n\nThese use cases are supported by Hyperbridge's developer resources, which include official documentation, GitHub repositories, research papers, and the Hyperbridge Explorer for transaction tracking. [\\[1\\]](#cite-id-PQjfyhfEj6s6nRLa)​\n\n## $BRIDGE Token\n\nThe $BRIDGE token is the native utility token of the Hyperbridge protocol, designed to power its decentralized functions and governance.\n\n### Tokenomics\n\n$BRIDGE has a capped total supply of 1,000,000,000 (1 billion) tokens. The protocol follows a deflationary model, as it does not mint new tokens for network security. Instead, fees collected from protocol usage accrue to an on-chain treasury, which funds network rewards and operations. The token is designed to be multi-chain native, maximizing its accessibility and utility across the integrated ecosystems. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\nThe initial token distribution was allocated as follows:\n\n* Onchain Treasury: 35%\n* Team: 20%\n* Token Sales: 13.3%\n* Foundation: 10%\n* Crowdloan Rewards: 5%\n* Community Incentives: 5%\n\nThe specified allocations account for 88.3% of the total supply; the distribution for the remaining 11.7% has not been publicly specified in the project's documentation. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz) [\\[4\\]](#cite-id-LchpZtBwS3oKDPaw)  [\\[5\\]](#cite-id-8btb3hnCjUNk8uI0) \n\n### Utility\n\nThe $BRIDGE token has several key functions within the Hyperbridge ecosystem:\n\n* Decentralized Governance: Token holders can create and vote on governance proposals concerning protocol parameters, such as fee structures, rewards, and software upgrades.\n* Cross-Chain Message Fees: Relayers are required to pay fees in $BRIDGE to submit cross-chain messages, which are then collected by the on-chain treasury.\n* Storage Query Fees: Fees for processing cross-chain storage queries are also paid in $BRIDGE and directed to the treasury.\n* Priority Fees & MEV: As part of its cross-chain sequencer function, relayers can pay priority fees in $BRIDGE to influence transaction ordering, creating a market for cross-chain MEV. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)\n\n## Security Incidents\n\nThe Hyperbridge protocol and its codebase have been associated with two notable security events.\n\n### April 2026 bridged.DOT Exploit\n\nOn April 13, 2026, the Hyperbridge protocol experienced a significant security breach. An attacker exploited a vulnerability in the protocol's gateway contract, which allowed them to forge messages and gain administrative control over the `bridged.DOT` token contract on [Ethereum](https://iq.wiki/wiki/ethereum). \n\nSubsequently, the attacker minted 1 billion unauthorized `bridged.DOT` tokens, realizing a profit of approximately $237,000. [\\[3\\]](#cite-id-FhkCfgqVSKZxBtgF)​\n\nThe incident caused the price of `bridged.DOT` to collapse to near zero. The price of the native [Polkadot](https://iq.wiki/wiki/polkadot) (DOT) token was also affected, dropping approximately 4% from 1.18. \n\nIn response to the exploit, the Hyperbridge team halted the protocol to prevent further damage and begin a full investigation. Major South Korean cryptocurrency exchanges, including [Upbit](https://iq.wiki/wiki/upbit) and [Bithumb](https://iq.wiki/wiki/bithumb), temporarily suspended deposits and withdrawals for the native DOT token. \n\nThe [Polkadot](https://iq.wiki/wiki/polkadot) team issued a statement confirming that the exploit was contained to the Hyperbridge protocol and did not affect native DOT or DOT bridged through other protocols. [\\[3\\]](#cite-id-FhkCfgqVSKZxBtgF)​\n\n### July 2024 bridged.gg Fork Exploit\n\nOn July 26, 2024, a protocol named `bridged.gg`, which was a fork of Hyperbridge's codebase, was exploited. The Hyperbridge team was not directly involved in the incident but released a public statement to clarify its non-association with the forked project. \n\nIn their statement, the team noted that they had previously advised the `bridged.gg` developers against deploying to a [mainnet](https://iq.wiki/wiki/mainnet) with unaudited code. [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)​\n\nThe Hyperbridge team stated on social media:\n\n> \"Earlier today, bridged\\_gg, a fork of the Hyperbridge codebase was exploited. We would like to re-iterate for the community, we are in no way associated with this team. \n> We had advised them on multiple occasions against deploying to mainnet with unaudited code. Our condolences go out to the users who have been affected by this unfortunate event.\" [\\[2\\]](#cite-id-CaW7cyxLPEu3aNUz)\n\n## Ecosystem and Integrations\n\nHyperbridge's primary focus is on providing interoperability for the [Polkadot](https://iq.wiki/wiki/polkadot), [Kusama](https://iq.wiki/wiki/kusama), and [Ethereum](https://iq.wiki/wiki/ethereum) ecosystems. The protocol has announced integrations with a number of chains, including:\n\n* [Astar](https://iq.wiki/wiki/astar)\n* Moonbeam\n* [Centrifuge](https://iq.wiki/wiki/centrifuge)\n* [Manta Network](https://iq.wiki/wiki/manta-network)\n* Composable Finance\n* Basilisk\n\nThese integrations allow for the transfer of assets and data between these otherwise siloed networks.
