Better proof

check.ts

tonProof.ts

nice.

So can we say we still have Wallet Signing to trigged the external message in TON>?

how to parse state init

How to create and send ton_proof message from front-end?

Well, tonapi returns 404 on that address. Is there a new approach to check the tonproof?

You need to use ton api v2
https://docs.tonconsole.com/tonapi/api-v2
use
v2/accounts/{account_id}/publickey

Figure 1 shows me making a request on the test network and getting public_key
Figure 2 shows that I made a request on the mainnet and couldn't get publick_key

I used the tonkeeper Google Wallet to get the address.
Does anyone know why?

public_key can be obtained using v2/tonconnect/stateinit

const { data } = await axios(
    `https://${
      body.network === '-3' ? 'testnet.' : ''
    }tonapi.io/v2/tonconnect/stateinit`,
    {
      method: 'POST',
      data: {
        state_init: body.proof.state_init,
      },
    }
  )

@peng-xiao-shuai thanks, that works!

Is there any other methods to get public key instead of tonapi.io? It is proprietary project and they can shutdown v2 api in few years how did they did it with v1

• Get the wallet pubkey via the contract wallet's get method. (https://tonapi.io/api-v2#operations-Connect-getTonConnectPayload) /v2/tonconnect/stateinit

• If the contract is inactive, this method will not work; you'll need to parse the walletStateInit provided by the frontend.
