# Contracts

The Vault system operates on a two-contract system:

The [Transferer](/welcome-to-the-harpie-docs/tech-and-security/contracts/transferer.md) contract has the ability to move your tokens to our noncustodial Vault. It cannot transfer your tokens anywhere else.

The [Noncustodial Vault](/welcome-to-the-harpie-docs/tech-and-security/contracts/noncustodial-vault.md) contract allows you to withdraw tokens that we've transferred. Only you can withdraw your assets out of the noncustodial vault: neither Harpie nor any other entity has the ability to withdraw assets on your behalf.

These contracts were designed to be easily-readable and easily-analyzed for any potential customer.
