Class HandleTokenManager

TokenManager that comes with native, wrapped native, and handle tokens by default. Handle supported token extensions:

isNative: true if token is native for that network (e.g. ETH, MATIC)
isHlpToken: true if the token is a hlp token in a handle Vault contract
isWrappedNative: true if the token is a wrapped version of a native token (e.g. WETH)
isStable: true if the token is a USD stablecoin, false otherwise,
isShortable: true if the token is shortable, false otherwise
isFxToken: true if token is a fx token, false otherwise
isLiquidityToken: true if token is the Handle Liquidity Pool token (symbol hLP), false otherwise

Note

the Handle Liquidity Pool token (symbol hLP) has isHlpToken set to false, as it is not technically in the liquidity pool. Instead, it has isLiquidityToken set to true
