for example, how to get Address? Is there a CDN for ton-core js library?

You can use some build system (rollup?), for example.

so there is no way I can use it like web3.js?

CDN also exists: https://unpkg.com/browse/[email protected]/

thank you I will try that out

Does anyone know if there is any example of myAppExplorerService?

I am actually looking for a way to check the status of my transaction, my smart contract will emit a log and I would like to read the logged message. But I have no idea how to make that happen and I cannot find any related documentation

You may have a look at an example that loads contracts interacting with certain address, checks their code and loads data: https://github.com/ProgramCrafter/ton-stable-timer/blob/master/web-interface/src/lib/load_timers.ts

thank you I will check that out

is toncenter official?

Yes, but you should use @orbs-network/ton-access because it doesn't have rate limits.

so TonWeb and Tonconnect serve the same purpose?

TonWeb+tonweb-mnemonic is similar to ton-core+ton.

I see, and TonWeb is under Toncenter so it is also official, am I correct?
