The Avalanche development team released the Durango upgrade and launched "Teleporter" to enhance interoperability in its subnet ecosystem. It is reported that Teleporter aims to unify Avalanche's specific application chain network and solve network fragmentation issues. It is built on Avalanche Warp Messaging (AWM) and supports EVM-compatible subnets, especially C Chain.

Patrick O'Grady, Vice President of Platform Engineering at Ava Labs, said: "With the activation of the Durango upgrade on the Avalanche mainnet, subnets can now use AWM to communicate locally with C Chain. Teleporter encapsulates this new functionality in an EVM-compatible interface, and Solidity developers can use this interface to trigger any contract call in any Avalanche subnet."
