OFTs
Frax assets are represented as OFTs (as defined by LayerZero) on chains other than Fraxtal, Ethereum, and Arbitrum. An OFT operates the exact same as an ERC20 with the additional function of bridge-ability through the LayerZero protocol.
Available Frax OFTs

Legacy vs. Upgradeable OFTs
In the initial deployment with LayerZero, the LayerZero team deployed Frax assets across several chains as fixed contracts. After the initial deployment, the Frax team has assumed additional deployment responsibilities and currently deploys OFTs as upgradeable, transparent proxies (contracts audited, repo link).
Legacy and Upgradeable OFTs maintain the same address per asset across chains, respectively.
All OFTs with bridging permissions are managed by a 3/6 msig on each respective chain.
