MetaMask has recently launched a new dApp called Portfolio, with a series of tools for users to monitor and manage their funds. With the launch of their Bridges aggregator, Metamask has selected Connext for its security and reliability to move tokens across chains.

15/6 Update!
Users are now able to perform
crosschain swaps directly in their wallet or MetaMask browser extension.

As explained by the MetaMask team, Connext was chosen for its security, trust-minimized design (one that doesn’t rely on external validators), and its ability to extend to multiple networks.

While we were chosen primarily for our best in class security, several other factors were seen favorably by the MetaMask team:

  • Recent and regular audits of the deployed contract code
  • Battle testing with time/volume on multiple mainnets
  • High liquidity and reliability
  • Robust handling of failure cases

This is part of a long-term synergy with both the Consensys and the Metamask teams.
In collaboration with ConsenSys, we recently co-published a guide on the different types of bridges available in the ecosystem today.

And Metamask released a guide on how to use Connext:

As usual, when using a bridge aggregator, it’s important to choose the most trust-minimized bridge to avoid exposing your funds to unnecessary risk.

Connext provides fast transactions with the lowest costs and the highest security possible.

About Connext

Connext is a network for fast, trustless communication between chains and rollups. It is the only interoperability system of its type that does this cheaply and quickly without introducing any new trust assumptions. Connext is aimed at developers who are looking to build secure bridges and other natively cross-chain applications. To date, over $1.5b in transactions have securely crossed the network.
