TON Connect V2 Proof verification

Better proof

tonProof.ts

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.

parse state init example on GO:
