QUESTION

Checking the number of confirmed blocks for a transaction?

Asked 2022-Mar-20 at 13:48

How does one check the number of "block confirmations" for a given transaction?

I tried checking the transaction hash in block heights of +1, +2, etc. but they don't contain the transaction ID.

Would I instead need to wait for future blocks to be mined, and the transaction status to still be considered valid? the Receipt.Status.

...

ANSWER

Answered 2022-Mar-20 at 13:48

After lots of research, I can say that it is the number of blocks that have been mined after the block your transaction was included in, and your transaction is still considered valid. So to check block confirmations, you would check whether the transaction is still valid, and see how many more blocks above the transaction block height have been mined.

Therefore, if your transaction has 13 block confirmations (see above graphic), then there have been 12 blocks mined since the block was mined that included your transaction.

The LOG opcodes are used for emitting event logs.

The value depends on the number of indexed and non-indexed topics of the event. Since the value is limited (currently at 4), there's also a limit of max indexed topics per each event definition (currently 3, so it's possible to process unindexed topics of the same event as well).

Example in Solidity:

ANSWER

Answered 2021-Nov-03 at 18:38

The ethclient.Dial function (which you mentioned) uses the rpc.DialContext function underneath, and the package also provides an ethclient.NewClient function to create a new ethclient.Client with an existing rpc connection.

A possible solution could be to create a new rpc connection, then pass it to the ethclient.Client, so you're using one connection, but can use the RPC connection itself and the eth client as well.

Something like this:

There is a bug in the JavaScript code.

From the documentation of signer.signMessage() (see the Note section), it appears that a string is UTF8 encoded and binary data must be passed as TypedArray or Array.
The Keccak hash is returned hex encoded, i.e. as string, and is therefore UTF8 encoded, which is incorrect. Instead, it must be converted to a TypedArray. For this purpose the library provides the function ethers.utils.arrayify().

The following JavaScript is based on the posted code, but performs the required hex decoding:
