AspisLiquidityCalculatorV3

Converts token amounts into their equivalent USD values using one of three supported adapters:

• Chainlink adapter
• Redstone adapter
• Uniswap adapter

Oracle Ids:

Adapter identifiers are hardcoded as keccak256 hashes of their names:

bytes32 public constant REDSTONE_ORACLE_ID = keccak256("REDSTONE_ADAPTER_ID");
bytes32 public constant CHAINLINK_ORACLE_ID = keccak256("CHAINLINK_ADAPTER_ID");
bytes32 public constant UNISWAP_ORACLE_ID = keccak256("UNISWAP_ADAPTER_ID");

These IDs must be mapped to their corresponding adapter contracts using (Guardian only):

    function updateOracleAdapter(bytes32 _oracleId, address _adapter, bool isPull) external onlyGuardian {
        adapters[_oracleId] = Adapter(_adapter, isPull);
        emit AdapterUpdated(_oracleId, _adapter, isPull);
    }

• _oracleId: One of the predefined Oracle IDs
• _adapter: Address of the adapter contract
• isPull: Whether the adapter uses a pull-based pricing model

Only Chainlink, Redstone, and Uniswap are supported. Adding new adapters requires a contract upgrade.

Also removeOracleAdapter can be used to delete the assigned adapter to an oracle Id:

    function removeOracleAdapter(bytes32 _oracleId) external onlyGuardian {        if (adapters[_oracleId].adapter == address(0)) {            revert AdapterDoesNotExist();        }
        delete adapters[_oracleId];
        emit AdapterRemoved(_oracleId);
   }

Assigning oracle ids to tokens:

Each token can be assigned a specific price oracle adapter. Once configured, the AspisLiquidityCalculatorV3 will exclusively use the assigned adapter to fetch that token’s price. Configuration functions (Guardian-restricted):

function setOracleForToken(address _token, bytes32 _oracleId) external onlyGuardian {}

function setOracleForTokens(address[] memory _tokens, bytes32[] memory _oracleIds) external onlyGuardian {}

• _token: address of token to update the adapter for.*
