# Bracket Protector
The Bracket Protector is the technical implementation ensure the security of the [Strategy Vaults](/product/bracket-platform/strategy-vaults.md). Our security protects the users who entrusted their assets to the strategy manager. Bracket Protector limits what a strategy manager can do what is approved within their whitelist, which includes:
* Moving between chains and using allowed bridges
* Assets that can be held
* Managing the withdrawal queue to ensuring users get their requested withdrawals
### **Policy Managed Wallets: non-custodial MPC wallet implementation**
The Bracket Platform extends its security into MPC (e.g. Fordefi) wallets by serving as a policy administrator, whitelisting protocols and addresses, with the ability to set permissions, limit withdrawals to the platform, and approve certain changes to the policies via administrative quorum within the wallet infrastructure. \
\
**This flow would involve an EVM chain, smart contract controls, MPC policy managed wallet, and supported DeFi protocols**
### Custodial use-cases
Bracket can also support custodial solutions where Bracket serves as a connecting infrastructure linking onchain assets to funds using custodial solutions like Zodia or Copper. These settlement networks combined with tri-party agreements can enable a custodial product for fund managers looking for a more traditional issuance approach.
### Bridging
Since a Bracket Protector contract has been deployed for each strategy on each chain, managers can bridge their Strategy vault's funds between chains, if allowed based on their investment policy. In the case Policy managed MPC wallets are used, similar bridging restrictions are enforced by their restriction mechanisms.
