I can't get Goerli Eth, is there a way to use Sepolia

Minimalforwader function of getNonce is not working
I have tried so many ways but it is still not working

Hi all,

I'm not currently building a marketplace yet, but very keen to better understand some of the concepts and best practices.

Let's say I want to build a marketplace that only shows the items that are created and minted there, not like OpenSea where you can see pretty much everything anyone owns in the currently active chain.

The tokens would be single items with one or multiple editions. Support for generative collections with thousands of unique tokens is not needed.

I've been looking at this workshop but a couple of things are not very clear to me yet:

1. what kind of contract would be ideal for this purpose with lazy minting
2. should we use just a single contract for everything that will be ever minted through the platform
3. related to item 2; what are the limits of tokens a contract can store

These are just some initial thoughts and nothing is built up yet.

Thanks all!

Hi, I wonder why i got this error

Error: call revert exception (method="getNonce(address)", errorSignature=null, errorArgs=[null], reason=null, code=CALL_EXCEPTION, version=abi/5.0.12)

Notes: I already make sure that Forwarder and Registry contract are deployed in Goerli and I call the contract with the deployed address (never run & test in local node for this project) so different network problem im pretty sure is eliminated.

It seems this function call is the cause of the error :

async function buildRequest(forwarder, input) {
  // console.log("go here?");
  // console.log(forwarder.address);
  // console.log(input.from);
  const nonce = await forwarder
    .getNonce(input.from)
    .then((nonce) => nonce.toString());
  return { value: 0, gas: 1e6, nonce, ...input };
}

Thanks before

In the AutoTask code the relay is defined with 4 arguments:

async function relay(forwarder, request, signature, whitelist)

and then it is called with 3 arguments:

const tx = await relay(forwarder, request, signature);

What sorcery is this?

Hi,
I´m having compilation issues with this file. https://github.com/OpenZeppelin/workshops/blob/master/01-defender-meta-txs/app/src/eth/signer.js

./src/eth/signer.js
SyntaxError: C:\Dev\repos\workshops-Oz\01-defender-meta-txs\app\src\eth\signer.js: Unexpected token (1:0)

> 1 | ../../../src/signer.js
    | ^

Any idea? Did I miss some step?

Hi,
I encountered an issue while using the OpenZeppelin Contracts Wizard on macOS(link). The copy-paste button for generated code doesn't seem to be functioning properly.

Steps to Reproduce:

1. Navigate to the Contracts Wizard page.
2. Complete the contract configuration.
3. Click the copy button to copy the generated code.

Expected Behavior:
The generated contract code should be copied to the clipboard.

Actual Behavior:

The copy button doesn't seem to work; the code is not copied to the clipboard.

Thank you for looking into this!

Hi All !
I am getting this error when i run the script npx hardhat run scripts/sign.js --network rinkeby (Rinkeby Testnet)

Sign authorization:
TypeError: Cannot read properties of undefined (reading '_signTypedData')
at main (/home/umer/OpenZepplineNFTMinting/scripts/sign.js:20:36)

How can i print these status of transaction on my dapp

I have tried your example workshops/25-defender-metatx-api and on running script scripts/sign.js got error:

Signing registration of alice as 0xA7C37aEfF34ac0994B3a350c56a591f321EbD8A3...
TypeError: forwarder.getNonce is not a function

Please help me to resolve this issue!

I've just tried the meta-transactions demo but found many errors when just following the instructions. It seems that it was published without checking that it works beforehand, which is bad practise.

Please fix all errors so that it actually runs.

e.g.:

Replace forwarder.verify(request, signature) with forwarder.verify(forwardRequestData) where forwardRequestData corresponds with ForwardRequestData.

Add deadline to the request.

Should EIP712Domain have salt?

Replace API_KEY with RELAYER_API_KEY and API_SECRET with RELAYER_API_SECRET in various files.

Replace apiKey with relayerApiKey and apiSecret with relayerApiSecret in the call to handler().
