# 3. Supplying Assets Supplying the pool’s lendable token mints fTokens that track your share (e.g., supplying ADA to the ADA/SURF pool mints fADA‑ADA/SURF). Every pool has its own flavour of fToken—so fADA from ADA/SNEK is distinct from fADA in ADA/SURF. How you earn: * The fToken price ticks up whenever borrowers repay—exact timing depends on user behaviour. * Cardano staking rewards flow into the pool every five days, boosting fToken price. * A share of Loan Opening fees and Liquidation fees will also be contributed to the pools on a regular basis. Flexibility: * You may add or withdraw supply anytime, even if you also have an open loan, so long as the pool has enough free liquidity. * Withdrawals settle through the same order queue; if liquidity is tight, the order waits until funds are available. No collateral token minted: Locking SNEK/SURF/etc. as collateral does not mint a new token—it’s simply held until you repay. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
