All - new to Github and learning Solidity. Could someone tell me if it is possible to copy or obtain a smart contract that has been proven to work on the blockchain in the past. I have a block number and the smart contract, how do I get the exact code used in that contract? Thanks.
If you go to a blockchain explorer like etherscan.io for Ethereum, you can pull up the contract code for a given address. For example, here’s how to view the deployed CryptoKitties contract:
CryptoKitties smart contract: CryptoKitties: Core | 0x06012c8cf97bead5deae237070f9587f8e7a266d
Etherscan.io has a ton of useful features and tools + works with test networks as well.
Thanks @loganbek - unfortunately Etherscan is not providing code info for the contract I am looking for. I’m getting tabs for Decompile Bytecode, Switch to Opcodes View and Similar Contracts.
@loganbek - it seems the contract I have been looking at is not verified. so I’ll not be able to see the code. It’s not verified like the CryptoKitties you sent, thanks.
Depending on what you’re trying to do with the contract, this could be helpful: Online EVM Bytecode Decompiler. Also I’ve seen this recommendation as well: Eveem. I think some decompilers do alright on simple contracts but most are going to struggle on anything complex and none are perfect from what I understand. If you just want to get a general idea of the contract it may be worth a shot though.
@loganbek - thanks, there is limited info even with these links. The source code is simply not available, but no worries as I have the basic steps the contract took. Thanks for the both links, I’ll tuck them away.
