Streaming Money Reservoirs – Technical Description

The primary component is a Dapp called a Reservoir. It acts as a DeFi Vault and manages supply to DeFi protocols. It also allows Superfluid money streams to flow in or out. A Reservoir is locked and only accessible via its creator wallet.

• A Reservoir is created by deploying the contract from a template.
• The wallet that creates the Reservoir can access the contract via a frontend.
  • (This is similar to Zapper, Zerion, and other finance management Dapps.)
• Config and parameters of the Reservoir can be modifed by the owner.
• The UI is a dashboard which shows all activity managed by the Reservoir.
  • It displays balances, incoming and outgoing streams, and DeFi supplies and rewards.
  • The connected DeFi protocols have parameters that can be adjusted.
  • The streams can be modified like any Superfluid stream.
• A proportion of the currency reserves can be supplied to DeFi protocols like Aave, Compound, Curve, etc.
• The allocations are managed automatically based on settings in the dashboard.

Creation

The steps to create a functioning Reservoir are:

• Visit the app site and deploy a Reservoir contract using an Ethereum wallet.
• Fund the Reservoir with currency.
• Setup streams for payments:
  • Each Superfluid stream must deposit a buffer bond, based on the flow rate.
  • These streams determine the minimum currency reserves required in the Vault.
  • Once flowing, the streams can be edited, e.g. reduced during low activity.
• When the outgoing streams are set up the remaining balance can be invested:
  • Choose desired DeFi protocols (Aave, Compound, Yearn, etc).
  • Configure parameters such as proportion of balance to be invested.
  • Make initial supply deposits.
  • Configure withdrawal parameters to keep the outgoing streams funded:
    • Withdrawals are triggered based on reserve balance proportions.
    • Depending on the currencies used some streams might need SuperToken swaps.
• If the Reservoir has incoming streams the steps are similar but with deposits.
  • Configure parameters (frequency, proportions) for new DeFI supplies.
