QUESTION
I am trying to deploy my SimpleStorage.sol contract to a ganache local chain by making a transaction using python. It seems to have trouble connecting to the chain.
...ANSWER
Answered 2022-Jan-17 at 18:17Had this issue myself, apparently it's some sort of Ganache CLI error but the simplest fix I could find was to change the network id in Ganache through settings>server to 1337. It restarts the session so you'd then need to change the address and private key variable.
If it's the same tutorial I'm doing, you're likely to come unstuck after this... the code for transaction should be:

QUESTION
I have smartcontract from HardHat tutorial https://hardhat.org/tutorial/writing-and-compiling-contracts.html
and I successfully deployed it.
...ANSWER
Answered 2021-Dec-18 at 10:31Not possible by design.
A contract address is determined from the deployment transaction params. Specifically, the ethers deploy() function is using the CREATE opcode by default, so the contract address is determined from the deployer address and the deploying transaction nonce param.
But the private key to the contract address is never generated during the deployment - so it can't be returned. Just the address.
Because otherwise I can't call the transfer method on the smart contract.
Correct. If you want to transfer funds out of the contract, you need to implement a function to be able to do that.
QUESTION
I tried all that you mentioned in the discussion here (in other questions) and at https://github.com/smartcontractkit/full-blockchain-solidity-course-py/discussions/522 , however it is not solving the issue for me, I also noticed that the current compiler version remains (current compiler is 0.6.12+commit.27d51765.Windows.msvc). But when I right click and select Solidty:Compiler information, it shows 0.8.0.

QUESTION
I have deployed a ERC-1155 based contract (based on OpenZeppelin) and minted some NFTs on this contract successfully. But when I want to use these NFTs in OpenSea, it always says "Unidentified contract".
Example: https://testnets.opensea.io/assets/0xc7d3e4a5A0c3e14ba8C68ea1b8a99a9dBf3ca76F/2
API-Example: https://testnets-api.opensea.io/api/v1/asset/0xc7d3e4a5A0c3e14ba8C68ea1b8a99a9dBf3ca76F/2/?force_update=true
Following their official Tutorial repository (which does not compile any more because of outdated dependencies and other issues) I have added some (maybe) opensea-specific functions and data that might required for OpenSea in order to work properly. However, OpenSea is able to grab all required data to display an NFT, but as long as they say "Unidentified contract", this all makes no sense so far.
My question has:
has someone already managed to deploy a ERC-1155 and used it with OpenSea properly without this issue? Is there anything we have to "register" somehow contracts that are not based on ERC-721?
🔢 Code to reproduce ...ANSWER
Answered 2021-Aug-27 at 22:07I finally found the root cause! OpenSea expects a public property called name in order to display the proper Name of the Collection instead of a static label Unidentified contract.
I came across this while looking at their reference code (which depends on a now 3-year-old MultiToken-Contract implementation and needs all in all some downgrades of Node and other tools in order to get it build [a downgrade to Node 10 worked best for me today] ).
QUESTION
So I'm currently trying to deploy a router smart contract. I've been building it through erdpy contract build, which has been successful (I'm on rust nightly tool chain as the Smart contract needs it). And I am now trying to deploy it, but I can't manage to do it. I keep having a 400 BadRequest from https://devnet-api.elrond.com/transaction/send.
Here are the logs from the deployment:
...ANSWER
Answered 2022-Jan-05 at 10:47I have you tried to deploy with the argument --verbose?
That should be something like that (not sure of the syntax because I am on phone)
erdpy --verbose contract deploy
QUESTION
ANSWER
Answered 2022-Jan-04 at 15:24I have encountered the same error. I had not changed the contract address once I deployed it to the testnet(Previously I deployed to localhost). Just check if the contract address you are using is of the contract you deployed to the testnet.

Install contracts
You can use contracts like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
