Send multiple txs at once and await the confirmation of them all

[0xrusowsky]

Hi,

I want to send multiple txs at once, so that all of them get included in the same block.
I want my script to perform further actions once the block is confirmed, so I also need to wait for the confirmation of all the txs. Nevertheless, I haven't been able to do so without awaiting each of them separately (therefore having them in different blocks).

This is what I have so far to send all of them in the same block, but I just need to await.

let lastNonce = await provider.getTransactionCount(KEEPER_ADDRESS);

targetPositions.forEach(async (position, index) => {
   const tx = await vault.closePosition(
      position.poolAddress,
      BigNumber.from(String(position.buyerNonce)),
      { nonce: lastNonce + index }
   )
   console.log(tx)
})

If you use the NonceManager you can achieve sending multiple transactions rapidly.

There is no way to guarantee they will occur within the same block, but they could. :)

ok, I'll try using the nonce manager then. Thanks ser!
