Polkadot Deep Dive: Balances Pallet

Polkadot Deep Dives are brought to you by Parity’s Delivery Services team, where each week they dive deep into all things FRAME, XCM and Polkadot governance. In this session, we dive deep into learning about the FRAME Balances pallet, from its high level features to its trait dependencies and how it can work alongside other pallets.If you have any questions, reach out to the community on our social channels 👇
