Karura uses an existential deposit (ED) to prevent dust accounts from bloating state. If an account drops below the ED, it will be removed from this account and be donated to the Treasury.
ED of native token KAR is configured in the runtime. Non-native tokens (KSM, kUSD, BTC etc) can be queried via SDK. The amount of ED can only be decreased, not increased, therefore it often starts with a higher number.
transfer and deposit in pallet_balances and orml_tokens will check the ED of the receiver account. A transaction may fail due to not meeting ED requirements, a typical one would be a user is swapping token A for token B, where token A balance no longer meets ED requirements. A front-end DApp shall perform checks and prompt user for such incidents.- Mint kUSD with KSM & lKSM:
- Liquidation penalty: 12%
- Stability Fee: 3%
Karura uses weight-based fees, unlike gas, are predictable and charged pre-dispatch. See the transaction fee page for more info.
Type definitions allow the SDK to know how to serialize / deserialize blocks, transactions and events.
