Bridging Blockchains with Avax Bridge
Avax Bridge is the official cross-chain bridge built by Ava Labs, enabling fast and secure transfer of assets between Bitcoin, Ethereum, and the Avalanche network. Powered by Intel SGX trusted hardware, Avax Bridge eliminates intermediaries and delivers true decentralized interoperability.
Intel SGX Security
Avax Bridge uses Intel SGX trusted execution environments to ensure bridge transactions are tamper-proof, private, and verifiable without relying on any central party.
Sub-Minute Transfers
Transfers via Avax Bridge typically complete in under one minute, making it one of the fastest cross-chain bridges available in the DeFi ecosystem today.
Multi-Chain Support
Move BTC.b, ETH, WBTC, USDC, USDT, and dozens more assets seamlessly across Bitcoin, Ethereum, and Avalanche with a single unified interface.
Built by Ava Labs
Avax Bridge is developed and maintained by Ava Labs, the core team behind the Avalanche blockchain, ensuring long-term support, security audits, and continuous improvements.
Our Mission
Avax Bridge was created with a clear mission: to make blockchain interoperability simple, secure, and accessible to everyone. In a fragmented ecosystem where assets are often locked within a single chain, Avax Bridge provides the essential infrastructure to move value freely across networks.
We believe that the future of decentralized finance depends on seamless cross-chain communication. By leveraging cutting-edge cryptographic technology and the performance of Avalanche, Avax Bridge sets a new standard for what a crypto bridge can be — trustless, transparent, and blazing fast.
Every design decision in Avax Bridge prioritizes the safety of user funds. From the Intel SGX-backed verification process to the open-source codebase, every component is built to give users maximum confidence when bridging their assets.
Key Features of Avax Bridge

- Near-zero fees: Avax Bridge charges a fixed 0.05% fee, significantly below industry average
- Real-time transaction tracking with full transparency via Avalanche Explorer
- Non-custodial design — your private keys never leave your device during bridging
- Integrated directly into the Core wallet for a seamless one-click bridge experience
- Audited by independent security firms with findings published publicly
Security Architecture
Security is the foundation of Avax Bridge. Unlike bridges that rely on federations of validators or multi-signature schemes, Avax Bridge employs Intel Software Guard Extensions (SGX) — a form of trusted hardware execution that creates isolated, tamper-resistant enclaves where sensitive bridge logic is executed.
This means that even if an attacker compromised the server running the bridge software, they could not access the signing keys or alter the bridge state. The SGX enclave produces cryptographic attestations that users and auditors can verify independently, ensuring the bridge is behaving exactly as designed.
Combined with rigorous smart contract audits, an active bug bounty program, and a transparent on-chain proof system, Avax Bridge represents the highest standard of bridge security currently available in the industry.
The Team Behind Avax Bridge
Avax Bridge is built and maintained by Ava Labs, a world-class blockchain engineering team founded in 2018 and headquartered in New York. Ava Labs created the Avalanche protocol and continues to drive innovation across the entire Avalanche ecosystem.
The Avax Bridge engineering team includes dozens of specialists in distributed systems, cryptography, and blockchain infrastructure, supported by a dedicated security research division that continuously monitors the bridge for emerging threats.
