Why can the same contract code be deployed unchanged on several chains?
Once a contract is deployed, its bytecode is fixed and anyone can view it. Whether the source code is available depends on whether the developer has verified it on a block explorer.
BNB Smart Chain, Avalanche's C-Chain, and many Layer 2 networks are EVM-compatible, so Ethereum wallets and development tools can mostly be used as-is.

Don't invest money you've borrowed. The pressure can lead you to make bad decisions.
