Cross-chain margin platform Prime Protocol is launching on Arbitrum

Quick Take

  • Prime protocol is launching its testnet on Arbitrum.
  • Many protocols have been moving over to or launching a version of the application on the Ethereum scaling platform.

Cross-chain margin platform Prime Protocol launched its testnet on Arbitrum today, and will be the first cross-chain brokerage that allows users to take out margin on their entire account — regardless of what chain they are on.

This is beneficial for users because it reduces liquidation and bridge hack risk, Prime Protocol founder Colton Conley told The Block.

Prime Protocol is using Axelar’s messaging technology to enable cross-chain transactions. It is also integrated with Wormhole, which gives Prime Protocol connectivity with non-Ethereum based chains.

It does not currently have a token live, but may at some point in the future, Conley said. Once live, it plans to run incentives to bootstrap liquidity. There may be an airdrop or some type of reward for people who participate on its mainnet, he added.

Many protocols — such as Polygon’s flagship derivatives exchange Gains Network — have added support for Ethereum scaling platform Arbitrum recently. Arbitrum is an Ethereum Layer 2 that currently has the highest market share in the sector, according to L2Beat. Prime Protocol is also integrated with Polygon, BNB Chain, Avalanche and Fantom.

Cross-chain applications have started to pick up some traction with interoperability platforms such as LayerZero, Axelar and Wormhole further along in their development. After some growing pains, building applications that mitigate the need to bridge are becoming more of a reality.
