Transactions are digital representation of value received or sent on chain or off chain.

Bitpowr currently has three types of transactions:

Deposit: These are simply transactions received in to any address you generated via Bitpowr. In double ledger accounting these are recorded as credits.
Transfer: These are transactions signed and sent out via Bitpowr to any address. These are recorded as debits and blockchain network fees are always present.
Contract Interactions: These are transactions that's related to contract interactions. It can either be a deposit or transfer base on the smart contract you are interacting with. However blockchain fees are always charged.
