What are the different networks on the Trader Joe platform?

Trader Joe's Decentralized Exchange is a 'multi-chain' platform that supports multiple networks. Trader Joe is able to offer users a variety of options for executing trades, with the ability to access new decentralized applications & tokens that are based on the different networks that can be accessed directly from the Trader Joe platform.

Changing networks on Trader Joe

When a user first visits the Trader Joe platform, the dapp will automatically connect them to their current Network. If a user wants to connect to a different network, to use the dapp on that network, a users can decide to switch networks by navigating to the network drop down button at the top right of your screen and selecting a network on offer (see below image).

What’s a “bridge”?

A bridge allows an asset on one chain to be sent to another chain. The purpose of a multi chain bridge is to allow users to take advantage of the unique features and capabilities of different blockchain networks. Bridges may use different cross-chain communication systems to facilitate the transfer of assets between blockchain networks.

Why would a user want to use a bridge on the JOE platform?

Users may want to utilize a bridge to access different networks available on the Trader Joe platform for a variety of reasons. As bridges allow users to easily transfer assets between these networks, they serve as a useful tool for users looking to take advantage of the unique features and capabilities native to each chain.

Bridging assets enables users to access new assets and resources that are exclusive to a particular network. For example, let’s say a user wanted to explore a new yield farming opportunity on Arbitrum, but only has funds on the Avalanche network. Through utilizing a bridge, the user could transfer their existing funds and gain access to native currencies on Arbitrum, allowing them to pursue attractive opportunities on the new chain.

Recommended bridges

Below you can find guides for the recommended bridges to transfer your assets across networks. If you have specific queries and need further assistance, please do not hesitate to join the Trader Joe Discord and speak to a community manager directly.

Bridge on JOE

By selecting 'Bridge' from the UI directly, users can transfer JOE tokens directly to and from different chains that the Trader Joe DEX is active on. This Bridge widget utilises LayerZero 'Omnichain Fungible Token' technology and essentially burns and mints JOE on different chains. This Bridge is safe, fast and it only costs you gas to use.


Stargate is a fully composable native asset bridge, and the first dApp built on LayerZero. DeFi users can swap native assets cross-chain on Stargate within a single transaction. For example, users can swap USDC on Ethereum for USDT on BNB.
