The Interoperability Protocol of L2 Ethereum.
=============================================

Connext is the leading protocol for fast, fully noncustodial transfers and contract calls between EVM-compatible systems.

Connext is the interoperability protocol of L2 Ethereum.

You can use Connext to send transactions of value or calldata across chains and/or rollups. Unlike most other interoperability systems, Connext enables this _without_ introducing any new trust assumptions or external validators.

Note that the current version of Connext cannot be used pass arbitrary event data between chains (i.e. prove to chain B that something occurred on chain A) as this cannot be done in a trust-minimized way in the evm except by incurring the 1-week exit window of existing rollup bridges.

This means that cases like **migrating** a token from chain A to chain B are not supported - you can instead only swap/transact over liquidity that already exists on the chain.
