hi all
i'm new to solidity development and exploring integration with provable API for REST calls thru oracle
i'm trying to deploy the sample provable API code provided in their github but facing gas estimation errors, both on ropsten as well as rinkeby
Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
execution reverted
any pointers/help on how this issue could be resolve would be greatly appreciated, because I'm not sure if i'm doing something incorrectly
“…if Bob has 50 coins on shard B, and Alice sends 20 coins to Bob from shard A, but shard B does not yet know the state of shard A and so cannot fully authenticate the transfer, Bob’s account state temporarily becomes ‘70 coins if the transfer from Alice is genuine, else 50 coins.’ Clients that have the ability to authenticate shard A and shard B can be sure of the “finality” of the transfer (ie. the fact that Bob’s account state will eventually resolve to 70 coins once the transfer can be verified inside the chain) almost immediately, and so their wallets can simply act like Bob already has the 70 coins.”
VB: "Clients that have the ability to authenticate shard A and shard B can be sure of the “finality” of the transfer almost immediately", How?

There is no EIPs talking about executing transactions in parallel by using evm in one block,
can some guys tell me why?
I'm working on improving the performance fo executing transactions


My job is to get all the method name from the token contract transactions from the beginning and to display the new transactions in realtime.

1) Get all events

For the moment I can display the "Transfer" events in realtime with:

```const targetContract = new ethers.Contract(
        "event Transfer(address indexed from, address indexed to, uint amount)",
targetContract.on("Transfer", (from, to, amount, event) => {

Otherwise when I try to recover the logs with INFURA:
INFURA.getLogs("0x30062EaBec018aC86430134E2c4Ff27e963Eda13").then((data) => { console.log(data); });

I don't understand what it shows me... It shows me a lot of information while there are not many events...

So for now I need to get all the events in realtime (and not just "Transfer") and to be able to get all the old ones. Like "Add Liquidity", "Max Tx" and other custom events

2) Get method name

I'm trying to decode method name from a TX.data but as I can see, with ethers.js or Infura it's not possible (or I missed something)

    [ "address user", "address rootToken", "bytes depositData"  ],     
    ethers.utils.hexDataSlice(data, 4) ));

I tried this but I need to provide the corrects arguments...

So well... if I can't decode without arguments my other choice it's to know if it's possible to just get the method name.

Then I searched a transaction in a shitty coin and I found this:

But when I'm using etherscan.io/api I don't have anything about the data (and not the method name)

In summary: I would just like to get the name of the methods and to be able to make a display like etherscan.io, like this:

Thank you!

Hi, I'm using eth_subscribe with newPendingTransactions, and it works great,
but when I try to take that transaction hash and send it to eth_getTransactionByHash The node doesn't know that transaction
what am I missing?

@SanJue Regarding executing transcations in parallel, please see EIP-2929 and others related to warm storage access. We can use specified storage slots to identify transactions that can run in parallel.

hey! I got a question regarding txns confirmations. I am using getTransactionReceipt to read the status of a transaction if it has failed or not. There are txns where although they have a transaction status of 0x0 I can see that they have been included in a block (a blockNumber exists in the response). Does this mean that the transaction has been confirmed? This is regarding simple txns. Now, txns that are sent to a contract, how can I check if the transaction has been confirmed on the chain but the contract execution failed? I am using geth as my node. Any help would be appreciated

Always its showing Insufficient ETH error even more than 10% slippage and double the gas fee.can anyone please suggest how to unwrap it
I tried with 20 % slippage also and with double gas fee

I'm trying to find out the symbol of the token that pays the fees for the network I'm currently in with python+web3. (https://stackoverflow.com/questions/69765460/how-do-you-get-the-network-symbol-in-pythonweb3)
Basically on ERC20 it should say "ETH" on BSC it should be "BNB".
For tokens I can get it from their contract using: tokenContract.functions.symbol().call()
But how do I find out which is the contract the network uses for fees?
Hi, Reddit announced they will be handling karma points as Erc20 tokens. I was wondering how this can be done with the high transaction fees? Wouldn't the fees exceed the value of the points? Are they using a 2nd layer solution?

Hello! The rinkeby faucet seems to be down. Would anyone be able to send me a few eth to deploy something to test net? 0xC33f2E51678FBdA19c441fc0aB3341d0FC07fb4A

<< everyone is optimistic about the rise and fall of the cryptos. personally, you can all agree with me that the bitcoin price is going to exceed its current value to $71,415 in February 2022, panelists have also predicted the bitcoin price to skyrocket to an average of $249,578 by the year 2024 which could also influence the price of altcoins. it's never too late to buy and hold of Ethereum/Bitcoin now is the right time. I personally have sustained over $567,000 since last year still now copying advance trade signals and indicating stop lost and manage risk following a mentorship and a blockchain specialist https://declanbrock.com/ his pattern are very lucrative with full of complex.

Hey All - I'm hoping there are some active folks here familiar with rlp encoding of 1559 transactions. I'm trying to write a wrapper in Elixir which sends London transactions. I'm encoding the following:
[chain_id, nonce, base_fee, gas_fee_cap, gas_limit, to, value, data, v, r, s] however it seems that the node keeps trying to return the transaction as a Legacy and so I feel like it is sending as Legacy since I'm receiving the following error:

2022-09-13 10:35:14.225 [error] Error: %{"code" => -32000, "message" => "rlp: input string too short for common.Address, decoding into (types.LegacyTx).To"}

Any input would be very helpful on this!
