EVM chain interoperability-focused project Connext has integrated Fuse Network. Fuse project developers can now integrate Connext’s bridging functionality into their DApps.
Establishing interoperability with other major blockchain platforms has always been a major part of Fuse’s vision for the crypto space. We believe that no single platform will be completely dominant and working together is imperative for fully realizing the technology’s potential and achieving genuine mass adoption.
Achieving interoperability requires enabling users to easily move digital assets and other messages between blockchains. The Fuse core team already operates a multichain bridge that currently connects the Fuse Network blockchain to Ethereum and Binance Smart Chain (BSC).
The Interoperability Protocol for EVM chains
Connext is a blockchain interoperability platform whose goal is to enable convenient and cost-effective non-custodial transfers of assets and calldata between blockchains.
Connext’s approach to bridge architecture is based on avoiding custody over bridged assets and introducing new security assumptions in addition to those involved with the blockchains between which the assets are moved.
This is achieved by using smart contract-governed liquidity pools on the supported blockchains that lock and unlock assets based on messages sent by users and special protocol participants called “routers.” A user wishing to bridge tokens from one chain to another locks the tokens in the Connext contract on the starting chain. A router who wins the right to execute the transfer at an auction then sends a message to the Connext contract on the receiving blockchain. If the transfer is not executed over the expiry period, the locked tokens are returned to the sender.
Routers can never obtain control over the users’ funds. The most damaging potential malicious behavior from a router is referred to as “griefing” and it involves a router failing to execute the transfer and making the sender wait until the release of the tokens they locked.
Currently, Connext’s remedy to this risk is maintaining a white list of routers but in the future, slashing will be introduced for misbehaving routers in a way similar to how misbehaving network validators are punished on multiple proof-of-stake blockchains.
How Fuse Integrates Connext
Connext has now added Fuse Network to the list of EVM-compatible blockchains it supports, which also includes, among others, Ethereum, BSC, Polygon, Fantom and Avalanche. It is now possible to bridge tokens to and from Fuse using the dedicated xPollinate user interface. The currently supported tokens include WETH, USDC, DAI and USDT.
DApp developers on Fuse can also integrate Connext-enabled bridging functionality into their products. More details on the implementation are available in Connext’s documentation.
The Fuse team is excited by the collaboration with a leading bridge operator and we hope that it will help boost Fuse’s interoperability with the leading EVM-compatible platforms.
