Metadata Contract

Metadata is a chain-singleton contract that stores branding and display information for each Monolith instance: social URLs, logos, project name, coin denomination, description, and an optional collateral USD price feed. It holds no funds and performs no protocol logic — it exists purely so that UIs can render consistent information for every deployed stablecoin. Contract source

Access control

All setters are guarded by the onlyOperatorOrManager(address _lender) modifier. A caller must equal ILender(_lender).operator() or ILender(_lender).manager() to set metadata for that Lender. Each Lender’s operator and manager therefore manage its own metadata independently; there is no global admin.

Types

enum CoinType { Stablecoin, Volatile }

struct MetadataValues {
    string   websiteUrl;
    string   xUrl;
    string   discordUrl;
    string   telegramUrl;
    string   otherUrl;
    string   coinLogoUrl;
    string   vaultLogoUrl;
    string   projectName;
    string   projectLogoUrl;
    CoinType coinType;
    string   coinDenomination;
    address  collateralUsdPriceFeed;  // optional; address(0) if market feed is already USD-denominated
    string   description;
}

Storage

Per-Lender mappings (all public, so each has an auto-generated getter):

websiteUrl, xUrl, discordUrl, telegramUrl, otherUrl
coinLogoUrl, vaultLogoUrl, projectLogoUrl
projectName, coinDenomination, description
coinType (CoinType enum)
collateralUsdPriceFeed (address)

Functions

setMetadata

function setMetadata(address _lender, MetadataValues calldata m) external

Batch setter that writes every metadata field for _lender in one call. Emits MetadataUpdated(_lender, m). Requirements:

msg.sender == ILender(_lender).operator() or msg.sender == ILender(_lender).manager()

getMetadata

function getMetadata(address _lender) external view returns (MetadataValues memory)

Reads all metadata fields for _lender as a single MetadataValues struct.

Individual setters

Each of the following sets one field and emits the corresponding *Updated event. All require msg.sender == ILender(_lender).operator() or msg.sender == ILender(_lender).manager().

function setDescription            (address _lender, string  calldata _description)            external;
function setWebsiteUrl             (address _lender, string  calldata _websiteUrl)             external;
function setXUrl                   (address _lender, string  calldata _xUrl)                   external;
function setDiscordUrl             (address _lender, string  calldata _discordUrl)             external;
function setTelegramUrl            (address _lender, string  calldata _telegramUrl)            external;
function setOtherUrl               (address _lender, string  calldata _otherUrl)               external;
function setCoinLogoUrl            (address _lender, string  calldata _coinLogoUrl)            external;
function setVaultLogoUrl           (address _lender, string  calldata _vaultLogoUrl)           external;
function setProjectName            (address _lender, string  calldata _projectName)            external;
function setProjectLogoUrl         (address _lender, string  calldata _projectLogoUrl)         external;
function setCoinType               (address _lender, CoinType          _coinType)              external;
function setCoinDenomination       (address _lender, string  calldata _coinDenomination)       external;
function setCollateralUsdPriceFeed (address _lender, address           _collateralUsdPriceFeed) external;
