Await transaction using `go-ethereum/ethclient`

Question

In ethers.js, one can wait for a transaction to be mined with wait(). Is there a way to do this when using ethclient from go-ethereum as a package? I would like to wait for the result before moving on in the program.

Answer 1

I think the function you are looking for is waitMined.

bind.WaitMined(context.Background(), client, signedTx)

Answer 2

Created this function that polls the client for a transaction, returns a channel that only unblocks once the transaction is confirmed (and sends said transaction over the channel)

// Returns a channel that blocks until the transaction is confirmed
func waitTxConfirmed(ctx context.Context, c *ethclient.Client, hash common.Hash) <-chan *types.Transaction {
    ch := make(chan *types.Transaction)
    go func() {
        for {
            tx, pending, _ := c.TransactionByHash(ctx, hash)
            if !pending {
                ch <- tx
            }

            time.Sleep(time.Millisecond * 500)
        }
    }()

    return ch
}
