- Define contract owner and error codes for various conditions - Set precision for price calculations to 6 decimal places
- Define `last-pool-id` data variable - Add `liquidity-pools` map to store pool details - Add `liquidity-providers` map to track provider shares
- Define `ft-trait` for fungible token operations - Implement helper functions: `mul-down`, `div-down`, `min`, and `transfer-token`
…utput - Implement `get-pool-details` to fetch details of a liquidity pool by ID. - Implement `get-provider-shares` to fetch the shares of a provider in a specific pool. - Implement `calculate-swap-output` to calculate the output amount for a swap given input amount and direction.
- Implement `create-pool` to allow the creation of a new liquidity pool with specified tokens and fee rate. - Ensure proper authorization and validation checks. - Update the `last-pool-id` variable upon successful pool creation.
- Implement `add-liquidity` to allow users to add liquidity to an existing pool. - Calculate shares to mint based on the provided amounts and current pool reserves. - Ensure proper authorization and validation checks. - Transfer tokens from the user to the pool and update pool and provider states.
- Implement `swap-exact-x-for-y` to allow users to swap a specified amount of token X for token Y. - Calculate the output amount based on the input amount and pool reserves. - Ensure proper authorization and validation checks. - Transfer input tokens to the pool and output tokens to the user. - Update the pool state accordingly.
- Implement `remove-liquidity` to allow users to remove liquidity from an existing pool. - Calculate the amounts of tokens to return based on the shares provided. - Ensure proper authorization and validation checks. - Transfer tokens from the pool to the user. - Update the pool and provider states accordingly.
- Implement `update-fee-rate` to allow the contract owner to update the fee rate of a specified pool. - Ensure proper authorization and validation checks. - Update the pool's fee rate and last block height.
