Staking
The Staking Contract contains the logic for LP Token staking and reward distribution. ANC tokens allocated for as liquidity incentives are distributed pro-rata to stakers of the ANC-UST Terraswap pair LP token.
Name | Type | Description |

staking_token | CanonicalAddr | Contract address of ANC-UST Terraswap pair LP token |
distribution_schedule | Vec<(u64, u64, Uint128)> | ANC distribution schedule for LP token stakers (start block [block], end block [block], distribution amount) |

Can be called during a CW20 token transfer when the Staking contract is the recipient. Allows the token transfer to execute a Receive Hook as a subsequent action within the same transaction.
