Fees and yield

How you actually earn

You earn through the share price, not by your share count going up. When the vault earns interest or harvests rewards, the value of one samSUI / samUSDC rises. Your number of shares stays the same; each one is just worth a little more.

So you never have to claim anything. Holding the token is enough. When you redeem, you get the higher value out.

The fees

Fee	Rate	When
Deposit	0%	none today
Withdraw	0.01%	taken from what you redeem
Performance	10%	taken from yield, before it compounds

The performance fee is the main one, and it only applies to profit. Of every 100 units of yield the vault earns, 90 lift your share price and 10 go to the protocol. You are never charged on your principal, and if the vault earns nothing you pay no performance fee.

Note

Every APY number shown in the app is already net of the performance fee, so what you see is what you would actually earn.

Reading the APY numbers

You will see a couple of different APY figures. They mean different things:

• Offered / current APY is a forward estimate: roughly what the vault’s current mix of markets is paying right now, including bonus token rewards, net of fees. It is what you can expect.
• Realized APY (7d / 30d) is what the vault actually earned over that window, measured from how much the share price grew. This is the honest, backward-looking number.

A per-protocol row may also show an APY. That is the rate a single market offers. SAM allocates by the yield it has actually measured on-chain, which can lag a freshly advertised rate, so a high-advertised market may temporarily hold less until its returns show up. This is deliberate: SAM commits capital to yield it has seen, not yield that is merely promised. See Rebalancing.

Bonus token rewards

Some markets pay extra reward tokens (like sSUI, BLUE, DEEP, or vSUI) on top of interest. You never have to claim or sell these. SAM harvests them, swaps them back into your vault’s coin, and compounds them into the share price for you. See Earning yield.
