What features does Crypto Wallet have in Developer Mode?
You can see many features in the developer mode of the crypto wallet. The main features are:
Testnet/Devnet Access: You can test transactions with test or fake coins instead of using real money or mainnet coins.
Custom RPC/Nodes: Connect the wallet to a self-created or custom node.
Console/API Access: Checking or debugging wallet data through coding or command line.
Advanced Tx Controls: Ability to manually set the gas fee or nonce for transactions.
Some private coins like Dero have their own wallets. In Developer Mode, can developers of that coin transfer coins from other people's wallets to another wallet?
The answer in one word is
no, it is never possible. Be it Dero, Monero (XMR) or Bitcoin any coin. Cryptography is the foundation of cryptocurrency. When you create a non-custodial wallet, its Private Key or Seed Phrase is encrypted only on your device. Even with privacy coins like Dero that have advanced homomorphic encryption, no one on the network can sign a transaction without your private key. Why developer mode, even the creator of that coin himself can't send a single cent from your wallet anywhere without your private key. If anyone could, it wouldn't be called crypto or decentralization, it would be a central bank. (If i'm wrong please correct me.)
