    hi

    Hey guys! How's it going? I'm new to DApp development but have a bit of web dev experience. I'm working on a simple Telegram bot to report Wanchain DApp stats. I've come across an issue which I think should be simple but I can't figure it out.

    I need to be able to get the block number for a specified time, anyone got any idea how do that?

    I think it will not affect node sync.

    Hello everyone, please upgrade your mainnet gwan to v2.1.6. Otherwise, the old version of gwan will not work after 22 Oct 2020.

    Hello, where can I read more about cross-chain data bridges? I am not interested in asset transfers, but only data transfer.
    Mo Lin
    @molin0000
    what do you mean of data transfer?
    Shaikh Farhan
    @98farhan94
    Is it possible to query states of other blockchains from the current chain (assuming wanchain supported)?
    More clearly, a smart contract that looks like an oracle, but functions as a data bridge.
    Mo Lin
    @molin0000
    I think no.
    Currently, only support assets crosschain.
    Shaikh Farhan
    @98farhan94
    Is it possible using WanChain infra, or is it on the roadmap?
    Mo Lin
    @molin0000
    you can use iWan which is like infura.
    It can get multi blockchain data.
    but not from smart contract.
    Shaikh Farhan
    @98farhan94
    Interesting, I will read more about it, thank you.

    @98farhan94
    Which chains are currently supported?
    Only ETH and BTC?
    Mo Lin
    @molin0000
    ETH, EOS, BTC
    Shaikh Farhan
    @98farhan94
    Is there a pricing for using it or do you need WAN tokens for access?
    Mo Lin
    @molin0000
    NO, free to use.
    Shaikh Farhan
    @98farhan94
    Amazing, thanks. Any rate limits?
    Mo Lin
    @molin0000
    I think it has rate limits.
    maybe 1 req/sec, i’m not sure.
    Shaikh Farhan
    @98farhan94
    Okay, thank you!
    I will test it out.

    @molin0000

    Hey Mo Lin, if we are building on Wanchain Open source Cross Chain liquidity, can we use Wanchain as our CrossChain liquidity partner on our website?
