These are bare wallets that are not connected to the Bitpowr private ledger account for internal settlement. Bitpowr has limited control over these types of wallets and seems like non-custodial wallets.
The end-users (mostly developers), will figure out how to handle every operation by themselves using the API. Each transaction from the wallet will incur a blockchain transaction fee. Funds in crypto wallets are not managed by Bitpowr and can only be moved by the end-users (developer)
These are wallets that are connected to Bitpowr private ledger account for instant internal settlements, connected to external fiat/crypto exchanges for fx. The developers have minimal control on moving funds from the addresses from these wallets as they are controlled by Bitpowr for easy fiat exchange and to save the tx fees. You can easily move funds between exchange wallets on Bitpowr network instantly with no tx fee.
These are types of wallets that are generated using the crypto wallet, connected to a private ledger account, and created as contract addresses on supported chains. All ETH, TRON, MATIC addresses are generated and deployed as a contract to each blockchain.
