Connext — an L2 Ethereum communication protocol. You can use it to send value transactions or call data across chains. Unlike most other interaction systems, Connext does this without introducing any new trust assumptions or external validators.
About the Connext project
It is a protocol, made up of many independent liquidity/infrastructure providers (called routers), that provides communication between chains. Developers can build cross-chain applications like DEX on top of Connext. Note that the current version of it cannot be used to pass arbitrary event data between chains (i.e. prove to chain B that something happened on chain A), as this cannot be done with minimal trust in evm, other than by rescheduling the 1-week exit window of existing drawbridges.
Overall, Connext — the only EVM-centric interaction system with minimal trust (no new security assumptions) and high return on investment (low user fees).
Other features:
| 1 | PoS/MPC systems - interaction structures where some external set of validators or oracles is responsible for moving data/value between chains. |
| 2 | Externally verified systems are generic and easy to build, but their security model is necessarily weaker than that of basic chains. |
| 3 | Platform does not have the same level of versatility as MPC systems, but it inherits its security from the underlying chains. |
Neither the Connext founding team nor any routers, using the Connext protocols, have any access to your funds. Due to the way Connext has appeared, the security of the system is the same as that of the underlying blockchain. Even if every router on the network, colluded with each other, they would have no way to access your funds.
More about defi app
The Connext network iteration uses nxtp, a lightweight protocol for general internetworking. Nxtp consists of a simple contract that uses a blocking pattern to prepare and execute transactions, a network of autonomous routers that participate in price auctions and pass call data between chains, and a user-side SDK that finds routes and proposes transactions within the network.
