VoltPool has increased the margin fee for VOLT to 1%. For context, the average margin across Cardano is 5.80%, so we remain well below average. There are several reasons for the change, but the main one is hardware upgrades — more RAM for the projected 1.28.0 upgrade that enables smart-contract functionality.
Hardware upgrade cost
Cardano is about to support smart contracts, which increases RAM usage on network nodes. VoltPool's servers are cloud-hosted, and we increased RAM on the block producer and relays.
Return on stake is higher
VoltPool has always had low variable fees, switching between 0–3% over the past year and now set between 0–1%. A variable-fee approach actually sustains a higher ROS for delegators over time while we maintain a return slightly above the 5% set by the Ouroboros protocol.
If you have any questions about the fee change, contact me via Twitter, Telegram, or email. Thank you for staking with VOLT — VoltPool wouldn't be here without you.
