|
|
|
| MeTokenRegistryFacet.sol |
Manages all state for a meToken within meTokens protocol. From it you can create your meToken and subscribe to a hub, resubscribe your meToken to a different hub, and transfer ownership of your meToken to another user. |

| HubFacet.sol |
Manages all hubs for meTokens protocol. A hub is a unique configuration for a bonding curve of which any meToken can subscribe to. When a meToken is subscribed to a hub, it will also use that hubs’ vault and underlying asset. |

| FeeFacet.sol |
Manages the fee rates for using meTokens, controlled by governance with a max rate of 5%. Fees for interacting with meTokens protocol may exist for: |
|
|
|
| • Minting a meToken |
|
|
|
|
| • Burning a meToken as a user for the underlying asset |
|
|
|
|
| • Burning a meToken as the meToken issuer for the underlying asset |

|
| UniswapSingleTransferMigration.sol |
Provides a SingleAssetVault that instantly swaps a meTokens’ underlying asset to a new asset when the meToken is resubscribing to a different hub with a different underlying asset. It uses Chainlink’s https://docs.chain.link/docs/feed-registry/ to fetch the spot price of the asset and provides a max slippage protection of 5%. |
