    Hello, is there a way to configure a testnet node to synchronize only from a specific block to the latest block? lets say i want historical data for 7 days and then to sync all the new ones. now my node tries to synchronize block from 2019

    hello - i have a tron node running, started from a snapshot, but its not syncing because all peers keep disconnecting. how can i keep syncing?
    Jayson Jacobs
    @j4ys0n
    do i have to manually find more peer ip addresses or will the node do that automatically?

    curl http://127.0.0.1:8090/walletsolidity/getnowblock 为什么会 返回 404 ？
    curl http://127.0.0.1:8090/wallet/getnowblock 是正常的。 是哪里的配置不对吗 ？

    @vivian-kang
    @flyingfz http fullnode 端口和solidity端口不一样，你看看配置文件中的http solidity端口配置的是什么

    hello, please is it possible get trc20 balance from hd wallet without activate wallet ?
    vivian-kang
    @vivian-kang
    If you want to transfer TRC20 token from HD wallet, you should activate the account address first.

    @sbaag123189042_gitlab
    @vivian-kang i know, but i want check to see if payment received before activate the account
    seems this script is ok: https://gist.github.com/andelf/7c2b6b176872ff0e83086828e6f16d2b
    but it say 100000 when wallet has 1$ trc20, or for example say 2000000 when wallet has 2$
    i know 1million sun = 1trx but i havent trx i have trc20
    vivian-kang
    @vivian-kang
    you can get the inactivated address's trc20 balance, but you cannot to transfer the trc20 from inactivated account

    @sbaag123189042_gitlab
    @vivian-kang yes i want do it but i think i didnt find good way yet, i tried tron api but it brings empty result, please which api i can use for inactivated address trc20 balance ?
    south bay
    @sbaag123189042_gitlab
    or do you know why that script say 1000000 for 1$ trc20 ?
    south bay
    @sbaag123189042_gitlab
    i succeed with this api: https://developers.tron.network/v4.0/reference/trc20-transaction-information-by-account-address
    its still showing "value":"2000000"
    i think i just want know why returns 1*1000000
    vivian-kang
    @vivian-kang
    Every token has precision, because the data on blockchain cannot be decimal. If the precision of a trc20 token is 6, and you have 1.1 token, the api will return 1.1* 1000000.

    @sbaag123189042_gitlab
    thanks a lot
    is precision for all trc20 wallets same ?
    flyingfz
    @flyingfz
    @vivian-kang 谢谢。 这个问题通过改配置文件已经解决了。 还有个问题， /walletsolidity/gettransactioninfobyid 这个接口的服务能力很成问题， 在内网其他机器请求这个接口，经常会得到 超时(超时的事件已经设置为15秒)的响应， 此时 节点服务器的 CPU 占用了大约20% （16核），内存 占用了大约 5G （32G），请问有没有办法提高这个接口的服务能力 ？

    is precision for all trc20 wallets same ?

    i mean is it 6 always for trc20 ? i cant find any document for this

    vivian-kang
    @vivian-kang
    No, each trc20 token may have different precision. you can check the token precision by triggering smart contract https://developers.tron.network/docs/trc20-contract-interaction#decimals
