> What could make savings in Obento lose value or wait.

Savings in Obento can lose value. Only put in what you can afford to lose.

## Smart contracts

The vault, Obento's additions to it and every place it lends to are smart contracts. A bug in any of them could lose money. Obento's additions have not had an independent audit.

## Lending

The places lend to borrowers against collateral. If collateral prices fall too fast for loans to be closed, a place can be left with bad debt, and pay back less than it holds. Protocol limits keep any one protocol to 40% of the vault.

## Liquidity

A place that has lent out almost all its money can't pay back at once. Large withdrawals may then wait until borrowers repay.

## USDC

Savings are in USDC. If USDC loses its dollar value, or Circle freezes it, savings lose value too.

## Operations

Withdrawals need a share price less than an hour old. If Autopilot stopped publishing it, deposits and withdrawals would wait until the team fixed it. A watchdog alerts the team within 35 minutes.

## Base

Obento runs on Base. If Base stops or slows, so does Obento.

## Rules where you live

Rules for crypto savings differ by country and can change.
