The new bridge is 5x cheaper than the Avalanche-Ethereum Bridge launched in early 2021.

Today marks the launch of the next generation of cross-chain bridging technology with the Avalanche Bridge (AB). The AB replaces the existing Avalanche-Ethereum Bridge (AEB) launched in February, and provides a significantly better user experience with stronger security, faster finality, and dramatically lower fees.

It is estimated to be 5x cheaper than the AEB, with a better user experience than any cross-blockchain bridges launched to-date. This breakthrough in bridge technology is built using Intel SGX Enclave technology, a breakthrough in secure computing that facilitates all operations in a closed environment and ensures it is tamper-proof.

The AB was designed to satisfy the following requirements:

  • Secure: the bridge must be audited and built with security-first technologies.
  • Cost Effective: the cost for bridging assets should be as low as possible.
  • Fast: the transaction should take the least amount of time possible.
  • Transparent: users should be informed of the transfer status at every step of the process.
  • Intuitive: users new to crypto asset transfers can easily understand the steps necessary to use the bridge.
  • Ecosystem-supportive: upon crossing the bridge, users should understand all of the capabilities of the Avalanche ecosystem and experience minimal friction in seizing opportunities.
  • Multi-chain: the bridge will support a growing number of blockchains in the future to center Avalanche as a core hub of DeFi.

“The new Avalanche Bridge is a leap forward in bridging technology, but most importantly, it is a dramatic improvement in experience for users and developers across the Avalanche community,” says Emin Gün Sirer, Founder and CEO of Ava Labs. “It will be a growth engine for the next phase of growth on Avalanche, and set a new standard for secure and efficient cross-chain interoperability.”

The bridge’s secure SGX Enclave establishes a consortium of trusted partners called Wardens. The Warden uses remote attestation technology to ensure that the bridge is operating securely within the enclave and running an audited version of the code.

In addition, the Wardens assist in the secure back-up and recovery of the bridge credentials, ensuring that funds held by the bridge are safe, while guaranteeing the integrity of each transaction. Wardens do not have as high of a technical burden as operators of other bridges, which is expected to enhance the reliability of the bridge operations.

At outset, the Wardens will be Avascan, BwareLabs, Halborn, and Ava Labs. Any operation requires verification and agreement from 3 out of 4 Wardens, and no Warden has the ability to act on the bridge without the other parties.

As part of launching the new bridge, existing assets that came across the AEB will be migrated to the new AB as it shows stability and performance in live production. Post-launch, all assets that cross over the AEB will be able to use the AB to bridge back to Ethereum, benefiting from the performance and economic improvements noted above.

The Avalanche Bridge is now accessible for both users and developers. Projects across the Avalanche ecosystem can now start preparing their integration to update DeFi applications and liquidity pools to the new token standards.
