How it works

This page explains where the yield comes from and how SuperVault turns it into a continuous stream. No technical background needed. For engineering detail, head to the developers docs.

The three steps

  1. You deposit USDC. Your USDC is routed into a yield-bearing vault that lends it out to earn interest.
  2. You receive a steady stream of yield. An annualised share of your deposit is paid to you every second as a Superfluid stream, straight into your wallet.
  3. You withdraw anytime. You get back your deposit plus the underlying vault's accrued value, net of what has already streamed to you.

Where the yield comes from

SuperVault does not generate yield by itself. It sits on top of an established lending vault — currently a Morpho vault curated by a professional risk manager.

SuperVault's job is to take that interest and reshape how it's paid: instead of quietly compounding inside the vault, a portion is streamed to you in real time.

The "stream," explained

A Superfluid stream is like a payment that drips continuously rather than arriving in lumps. Picture a tap: once it's open, money flows at a fixed rate per second into your wallet. SuperVault opens that tap for you the moment you deposit.

  • The rate is expressed as an annualised percentage of your deposit, but it's paid per second, so your balance grows smoothly and visibly.
  • Because the stream pays into your own wallet, the yield is yours as it accrues, there is nothing to claim.

The displayed streaming rate is intentionally a little below the raw vault APY. SuperVault offers a stable, predictable stream. The difference between the raw vault APY and the streaming rate is accrued (auto-compounding) to your principal.

Stable stream + the upside

There are two pieces to what you earn:

  1. The promised stream — a steady, stable rate that flows to you every second. This is the headline number you see in the app.
  2. The surplus — if the underlying vault earns more than the promised rate, that extra value accumulates in the vault and is reflected in what your position is worth when you withdraw.

So the stream gives you predictable, real-time income, and the surplus means you still benefit if the underlying market does better than expected. The two are never double-counted.

The fees

A small protocol fee is taken on the yield (not on your principal). In the demo, 1% of the total yield streamed to users is streamed to the Superfluid DAO (dao.superfluid.eth).

Additionally, 0.20 USDC fee is taken on your deposit in order to cover for the full gasless experience within the app.

What you hold

When you deposit, you receive vault shares that represent your position. Your share of the vault determines:

  • how much principal you can withdraw, plus
  • your slice of any surplus the underlying vault has earned.

Meanwhile the live stream pays the promised yield into your wallet second by second. You can think of it as: shares = your stake and its upside; stream = your steady income.
