Where your funds go

When you deposit, SAM doesn’t just hold your coins; it lends them out across several established Sui money markets so they earn interest. Your deposit is split across all of them at once.

The markets

Protocol	What it is
Scallop	A major Sui lending market.
Suilend	A lending protocol; SAM uses its main pool plus a few isolated markets (Ember, Matrixdock).
NAVI	A lending protocol; the USDC vault also earns a Volo (vSUI) reward there.

Spreading across multiple venues means you are not exposed to a single market’s rate or a single market’s risk. The samUSDC vault, for example, is deployed across Scallop, Suilend’s main pool, two Suilend isolated markets, and NAVI at the same time.

Adapters

SAM talks to each market through a small connector called an adapter. The adapter knows how to deposit into that specific protocol, withdraw from it, read how much yield it has earned, and harvest any bonus reward tokens it pays.

Each adapter is gated so that only it can move that protocol’s funds, and only on the vault’s behalf. This is what keeps the whole system safe: funds can only ever move through code that is allowed to, and that code always deposits into the real market or returns the money to the vault.

The idle buffer

Not everything is deployed. A fraction of every vault (default 5%) is kept idle: liquid and ready, so that everyday withdrawals are instant and never have to wait on a lending market. See Staying liquid.
