If I can't use the most recent Github version web3j is completely useless to me because the current release version has an issue that requires me to change the source code.
Hi Team, Sorry I'm new here but I'm having issues with Web3j , when I connected to Polygon Mumbai network Contract deploys and Contract Writes goes to a Pending State for like 15 -30 min and then disappears, i can read contracts without errors on Polygon , when i connected to Goerli Testnet Network though Deploys and Writes works within seconds , do i have to configure these 2 networks differently? any pointers ?
I've posted this on StackOverflow with more details hope it's ok to link it here for reference - https://stackoverflow.com/questions/70560195/web3j-pending-transactions-on-polygon-mumbai-network-but-works-with-goerli-testn
Hi, I am new to web3j and was going through readme and found a wrong link and some incomplete instructions can i raise a issue for this?

Hi, it is mentioned in project readme that web3j works on http and ipc transport , is there any way to connect to remote ethereum nodes using tcp as most nodes may not have http started by default?
Hi there, did anyone encounter:
A problem was found with the configuration of task ':npmInstall' (type 'NpmInstallTask').
No value has been specified for property 'packageJsonFile'.
The web3j gradle plugin uses old node and solidity gradle plugins, that are only compatible with gradle version 5.x and not 6.x or even 7.x. If you want to be able to use it with at least version 6.x you need to specifically apply newer version of these plugins: node 3.1.1 and solidity 0.3.2
id "org.web3j" version '4.8.8'
id "com.github.node-gradle.node" version '3.1.1'
id "org.web3j.solidity" version '0.3.2'
Hi everyone, I noticed this issue has been opened for a year web3j/web3j#1580 and the rpc call ethGetFilterChanges it's broken in hardhat and everything I could find. I was trying to use Eventeum, which seems abandoned for another closed source solution, as I applied the patch it started working but not for contract monitoring, and I was wondering if there was someone I could contact to get more information on this issue and why those functions are not compliant with the rpc-json specification.
TransactionReceipt receipt = Transfer.sendFundsEIP1559(
web3j, credentials,
toAddress, //toAddress
BigDecimal.valueOf(1), //value
Convert.Unit.ETHER, //unit
BigInteger.valueOf(8_000_000),
DefaultGasProvider.GAS_LIMIT, //maxPriorityFeePerGas (max fee per gas transaction willing to give to miners)
BigInteger.valueOf(3_100_000_000L) //maxFeePerGas (max fee transaction willing to pay)
).send();
System.out.println(receipt.isStatusOK());
System.out.println(receipt.getTransactionHash());
otherwise , Transfer.sendFunds is work fine
`const getHistoryTransactionFromWeb3 = async (
transactionHash: string
) => {
let newAmount;
await web3.eth.getTransactionReceipt(transactionHash, (err, result) => {
newAmount = Number(result.logs[1].data);
});
return newAmount;
};`
Whats the web3j equivalent to this web3js function
Hi All, I was thinking is somebody working on a server for artist or creatives to self host and only those who have a specified nft will have access to resources inside the server. So artist releases nft and that gives user streaming access to songs in a album.
Hi Devs, For web3j sokt versions after 0.7.2 all windows url are empty and can not use the solidity compiler on windows.

Hi, is there any info on when the next release of

Hi everyone! I have a question regarding web3j core versions. On the Maven repository, the latest version (considering version numbers) of web3j core is 5.0.0, but it was released in May 2020. Version 4.9.0 looks like the newest one, released in February 2022. 4.9.0 is the latest on Github too. Which version should I use? I assumed that I should use 4.9.0, but I decided to ask this question nevertheless.
And a second question: is the Ledger signature format supported somehow? Using Sign.signedPrefixedMessageToKey() on a Ledger signature throws SignatureException with message: "Header byte out of range: 1". Shifting the V byte + 27 (+ 0x1B) solves the problem, but maybe I'm unaware of something.
Hello everyone! I'm trying to call a custom function of my smart contract deployed on ropsten by using java wrapper class, but I always getting the error:
org.web3j.protocol.exceptions.TransactionException: Transaction receipt was not generated after 600 seconds for transaction
I think the problem should be the gasPrice value, can someone please help me?
I'm using these values:
BigInteger gasPrice = new BigInteger("22000000000");
BigInteger gasLimit = BigInteger.valueOf(100000);
Thanks in advance.

val contract = Contract.deploy(web3j, Credentials.create(Keys.createEcKeyPair()), DefaultGasProvider(), "Name", "Symbol").send()java.lang.IllegalStateException: worldState.get(Address.f…String(w3jAddress.value)) must not be null
val ethEstimateGas = mPancakeSwapRepo.WEB3J.ethEstimateGas(mTransaction).send()
No matter whether the method is executed successfully or not, I will get an error free result
maven plugin error: not found: File outside of allowed directories.
how to fix that?
Hi, with web3j, I'm trying to decode binary data of a simple tuple like (uint256,string). Although I can encode like
final Type uint256Type = TypeDecoder.instantiateType("uint256", 12345);
final Type stringType = TypeDecoder.instantiateType("string", "foo");
final DynamicStruct dynamicStruct = new DynamicStruct(List.of(uint256Type, stringType));
final String encoded = TypeEncoder.encode(dynamicStruct);I cannot decode the data back. Is there a way to decode a tuple without generating classes, etc.
