Does holding only sufficient asset in statemint imply there is no ED for the account?

Question

Do I need to account for ED when transferring Sufficient asset from statemine to parachain?

Answer 1

Does holding only sufficient asset in statemint imply there is no ED for the account? Yes, Sufficiency means that the asset balance is enough to create the account on-chain, with no need for the DOT/KSM existential deposit.

But, you cannot send a non-sufficient asset to an account that does not exist. For that you need the existential deposit of the account in the native token:

The native token of Statemint is DOT. The Existential Deposit (ED), transfer fees, and the deposits for proxy/multisig operations on Statemint are about 1/10th of the values on the Relay chain. For example, the Existential Deposit of a Statemint account is 0.100 DOT, when compared to 1 DOT on Polkadot.

See the code where the ED is set.

Statemine is the Parachain on Kusama, see the code here.

Do I need to account for ED when transferring Sufficient asset from statemine to parachain? Sufficient assets can be used to pay transaction fees (i.e. there is no need to hold DOT/KSM on the account).
