<summary>Does the protocol charge fees ?</summary>

Lagoon has the capacity to activate a fee switch at the protocol and vault level. Those are capped at 30% and are taken on the fees of the curator. Currently no vault is subject to fees.\
\
\&#xNAN;*Example:*\
*A curator generates 1000 shares of fees through management and performance fees. The protocol fee rate is 10% for this vault. Lagoon will receive 100 shares and the fee receiver 900 shares.*

<details>

<summary>Can a vault do cross-chain strategies ?</summary>

The strategies a curator can execute are exclusively limited by the curation solution he used.&#x20;

For example, a vault curator using a Safe can bridge funds across EVM chains, non-EVM chains, and even CEXs.&#x20;
