# Mainnet Vault Pool The Vault Pool is a collection of Bitcoin addresses managed by the FROST Network and used to receive and store user-deposited BTC. #### Vault Address Allocation When a user initiates a deposit, the system allocates an address from the Vault Pool. * Address selection considers current balance, capacity limits, and distribution strategy * The selected address is returned to the user to complete the BTC transfer #### Vault Capacity and Rotation As BTC accumulates in a Vault address and approaches its capacity limit, the system updates address usage and allocation. * Each Vault address has an asset capacity limit (e.g., 1000 BTC) * Addresses nearing capacity are no longer used for new deposits * New Vault addresses may be generated and added to the pool, or a portion of assets may be transferred to designated cold storage addresses under the same threshold signing configuration * Addresses no longer receiving deposits remain available for fund management and subsequent transfers --- # 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.
