Cryptocurrency bridging

I would think that you only use that bridge for sending transactions, in case that the bridge already exists as a set of smart contracts.

I’m getting a cloud function error on my server https://5mvwcjt1udmr.usemoralis.com:2053/server. Any way someone can see what’s going on for my cross chain bridge

alex · May 29, 2022, 10:41pm

Can you please make another post with more details - what the error is, what your cloud function is.

First of all, your addresses and speedy nodes need to be inside the strings. E.g.

const web3Main = "https://speedy-nodes-nyc.moralis.io/602c31f2fce703bb491b08fb/bsc/mainnet";
...
const MainBridge_address = "0xd70697B620437Db03c2b0DBE4A1404b8e36bE810n";
...

Also your MainBridge and SideBridge won’t work, you’re trying to call web3.js methods on strings.

Make sure you’re following your tutorial properly and check that your code matches.

ben070292 · May 29, 2022, 11:36pm

Ok got those fixed no only error I get is undefined is all it says

alex · May 29, 2022, 11:37pm

What have you done so far now and what is the tutorial you’re using?

ben070292 · May 29, 2022, 11:38pm

https://youtu.be/UkWj7rwOGGc Is the tutorial

alex · May 29, 2022, 11:40pm

You can view all of the final code here to compare with your own.

ben070292 · May 29, 2022, 11:49pm

Yes I got the code there my man fixed the address (); with this
