updateCurrency(currency, data)

Feature	Return raw operation for creating a new currency policy. Signature of nodes is required, not a general account signature.
Parameters	string currency ID, object currencyPolicyData
Return Value	object operation to update currency policy

// [ parameter for currencyPolicyData structure ]

type currencyPolicyData = {
        initialSupply: string | number | Big
        minBalance: string | number | Big
        feeType: "nil" | "fixed" | "ratio"
        feeReceiver: string | Address         // receiver address
        fee?: string | number | Big           // need to assign when feeType is "fixed" or “ratio”
        ratio?: number
        minFee?: string | number | Big
        maxFee?: string | number | Big
}

• feeType is optional and can be one of "none", "fixed", or "ratio".

  • "none" means no transaction fee is collected.

  • "fixed" collects a fixed fee, so you must enter a fee receiver address "feeReceiver" and a fixed fee "fee".

  • "ratio" collects a percentage of the transaction volume, so you must provide the address "feeReceiver", the fee ratio "fee", the minimum fee "minFee", and the maximum fee "maxFee".

example

const currencyID = "SIT";
const decimal = 9;
const inputData = {
    minBalance: 5,
    feeType: "fixed",
    feeReceiver: "0xdCA5d22F192a5703d629602c25AC7252cE94dBa8fca",
    fee: 3,               // 3%
    minFee: 5,
    maxFee: 10000,
}

const rawOperation = mitum.currency.updateCurrency(currencyID, inputData);
console.log(rawOperation);
