The perfect library for building Bitcoin-based applications.

import BigNumber from 'bignumber.js';
BigNumber.config({
    EXPONENTIAL_AT: 1e9,
    DECIMAL_PLACES: 18,
});
export class BitcoinUtils {
    static formatUnits(value, decimals = 8) {
        const bn = new BigNumber(value.toString());
        return bn.dividedBy(new BigNumber(10).pow(decimals)).toString();
    }
    static expandToDecimals(n, decimals) {
        const amount = new BigNumber(n)
            .multipliedBy(new BigNumber(10).pow(decimals))
            .decimalPlaces(0);
        return BigInt(amount.toString());
    }
