Every cost of a send on the Elysium multisender, paid in HYPE
The Tokenry fee is 0.0015 HYPE per recipient, paid to Tokenry and only for delivered payouts. Gas is paid in HYPE to the network, per transaction, and your wallet shows it before you confirm.
A token approval, paid in HYPE as gas, is needed only for a token that cannot be sent by signature, or when you send from a smart-contract wallet. A refused payout is skipped: its gas is spent, but its Tokenry fee, and its amount on a HYPE send, come back to you in the same transaction. A reverted transaction pays nobody and takes no Tokenry fee, but the gas is spent.
The Tokenry fee for common list sizes, before gas: 100 recipients cost 0.15 HYPE, 400 recipients cost 0.6 HYPE and 1,000 recipients cost 1.5 HYPE.
On Elysium the Tokenry fee, not the gas, is usually the larger part of a send's cost. Elysium also charges no parent-chain data fee, so gas is the only network cost (Kinetiq: blocks, fees and ordering).
