How to get transaction hash?

[7JUMPER7]

How to get transaction hash after I create it with:

const transfer = walletContract.createTransfer({
                seqno: seqno,
                secretKey: keypair.secretKey,
                messages: [internalMessage],
            });

and sent with:
await this.client.sendExternalMessage(walletContract, transfer);

When I call transfer.hash().toString("hex"), it gives me hash which is different from what I see on tonviewer.

Any updates on that? Having the same issue

transfer.hash().toString("base64") gives you what shows tonviewer

No. There is my hashes from transfer.hash():
base64: 5/VSswqg7BTCcdfBYXYKdosyU6U5SHZD9DZ575m01kI=
hex: e7f552b30aa0ec14c271d7c161760a768b3253a539487643f43679ef99b4d642

When I enter base64 to TonViewer, I have hex hash in domain string and 404 message on the page.

Can you provide the wallet of that transaction?
P.S. Can't see the image

This is mainnet, wallet: UQDSFFpQzCNjL3uOhwpGoEkLa67Tsjlq346VuMvtCM3bGFcu

Send the transaction too please, or it can be any?

There it is: https://tonviewer.com/transaction/72468f5599057f3cc36a75bbddbddba5d3317abc449c117db3b698ed94ba3982

I have found a solution
The problem is that the final BoC is formed immediately before sending the transaction, and there is there is no built-in way to get its hash
So, it can be retrieved and returned in the functions external or sendMessage of the file @ton/ton/dist/client/TonClient.js
I rewrote the end of the function external (line 358) as follows

let final_cell = (0, core_1.beginCell)().store((0, core_1.storeMessage)(ext)).endCell()
let boc = final_cell.toBoc()
await client.sendFile(boc)
return final_cell.hash().toString('hex')

And function sendMessage (line 168) that way

async sendMessage(src) {
        let final_cell = (0, core_1.beginCell)().store((0, core_1.storeMessage)(src)).endCell()
        const boc = final_cell.toBoc();
        await __classPrivateFieldGet(this, _TonClient_api, "f").sendBoc(boc);
        return final_cell.hash().toString('hex')
}

Next, you need to track calls to this function up the tree and pass the hash value

For example

File @ton/ton/dist/client/TonClient.js (line 195)

 async sendExternalMessage(contract, src) {
        if (await this.isContractDeployed(contract.address) || !contract.init) {
            const message = (0, core_1.external)({
                to: contract.address,
                body: src
            });
            return await this.sendMessage(message);
        }
        else {
            const message = (0, core_1.external)({
                to: contract.address,
                init: { code: contract.init.code, data: contract.init.data },
                body: src
            });
            return await this.sendMessage(message);
        }
    }

File @ton/ton/dist/wallets/WalletContractV3R2.js (line 60)

async send(provider, message) {
    let hash = await provider.external(message)
    return hash
}

File @ton/ton/dist/client/TonClient.js (line 407)

let hash = await via.send({ to: address, value, bounce, sendMode: message.sendMode, init: neededInit, body})
return hash

If you're using DeDust SDK
File @dedust/sdk/dist/contracts/jettons/JettonWallet.js (line 24)
return await provider.internal(via, {...

File @dedust/sdk/dist/contracts/dex/vault/VaultNative.js (line 62)

let hash = await provider.internal(via, {sendMode: core_1.SendMode.PAY_GAS_SEPARATELY, body: cell, value: amount + (gasAmount ?? (0, core_1.toNano)('0.2'))})
return hash

I followed your method and i got something back, but one issue the transaction hash differs from the one on the explorer.
previously without your code i do not get a reply at all

const hash = await contract.sendTransfer({ secretKey: KEYPAIR.secretKey, seqno, messages: [ internal({ value: amount, to: toAddress, }), ], sendMode: 3, });

in creating my wallet instance i use
WalletContractV4.create({ endpoint })

Do you think there would be a better update in the future, because the lib encounters an error it stops my code from running even when i have a try..catch block

Bro your solution works, thanks man
