Kusama: $-based parameters

::indices

IndexDeposit

Value

1 * DOLLARS

Description

The deposit needed for reserving an index.
https://github.com/paritytech/substrate/blob/v3.0.0/frame/indices/src/lib.rs#L51-L52

::balances

ExistentialDeposit

Value

1 * CENTS

Description

The minimum balance required to create or keep an account open. This prevents "dust accounts" from filling storage. When the free plus the reserved balance (i.e. the total balance) fall below this, then the account is said to be dead; and it loses its functionality as well as any prior history and all information on it is removed from the chain's state.
No account should ever have a total balance that is strictly between 0 and the existential deposit (exclusive). If this ever happens, it indicates either a bug in this pallet or an erroneous raw mutation of storage.

https://github.com/paritytech/substrate/blob/v3.0.0/frame/balances/src/lib.rs#L41-L47

::transaction-payment

TransactionByteFee

Value

10 * MILLICENTS

https://github.com/paritytech/substrate/blob/v3.0.0/frame/democracy/src/lib.rs#L565-L566

::elections-phragmen

CandidacyBond

Value

1 * DOLLARS

::identity

BasicDeposit

Value

10 * DOLLARS

Description

The amount held on deposit for a registered identity.
https://github.com/paritytech/substrate/blob/v3.0.0/frame/identity/src/lib.rs#L104-L105

FieldDeposit

Value

250 * CENTS

Description

The amount held on deposit per additional field for a registered identity.
https://github.com/paritytech/substrate/blob/v3.0.0/frame/identity/src/lib.rs#L107-L108

SubAccountDeposit

Value

2 * DOLLARS

Description

The amount held on deposit for a registered subaccount. This should account for the fact that one storage item's value will increase by the size of an account ID, and there will be another trie item whose value is the size of an account ID plus 32 bytes.

::recovery

ConfigDepositBase

Value

5 * DOLLARS

Description

RecoveryDeposit

Value

5 * DOLLARS

Description

The base amount of currency needed to reserve for starting a recovery.

This is primarily held for deterring malicious recovery attempts, and should have a value large enough that a bad actor would choose not to place this deposit. It also acts to fund additional storage item whose value size is sizeof(BlockNumber, Balance + T * AccountId) bytes. Where T is a configurable threshold.

https://github.com/paritytech/substrate/blob/v3.0.0/frame/recovery/src/lib.rs#L202-L209

::society

CandidateDeposit

Value

10 * DOLLARS

Description

The minimum amount of a deposit required for a bid to be made.
