A gist to generate last N repeated characters Tron account based on tronweb

app.js

// N x repeated characters
const LEN = process.argv.length > 2 ? parseInt(process.argv[2]) : 4
console.log('LEN: ' + LEN)

function check(s) {
    let i = s.length - LEN
    const p = s.charAt(i)

    for (i++; i<s.length; i++) {
        if (p != s.charAt(i)) {
            return false
        }
    }

    return true
}

function parse(data) {
    const addr = data.address.base58
    if (check(addr)) {
        console.log('found: ' + addr)
        fs.writeFileSync('./output/' + addr, JSON.stringify(data))
    }
}


function main() {
    TronWeb.createAccount().then(parse).catch(console.error)
}

setInterval(main)
