# Overview

> HIFI Wallets are managed, multi-chain wallets HIFI provisions and secures for each user, alongside external wallets, on-chain deposits, and Canton deposit offers.

Wallets are how value moves on-chain in HIFI. Every user can have one or more **HIFI Wallets** - managed wallets that HIFI provisions per chain - plus any number of **External Wallets**, which are whitelisted third-party addresses used as withdrawal destinations.

This section covers four resources:

| Resource                                            | What it's for                                                                                            |
| --------------------------------------------------- | -------------------------------------------------------------------------------------------------------- |
| [HIFI Wallet](/v3/core/wallets/hifi-wallet)         | Provision managed wallets, fetch wallet details, and read live on-chain balances.                        |
| [External Wallet](/v3/core/wallets/external-wallet) | Register and manage non-custodial addresses tied to a counterparty.                                      |
| [Deposit Offers](/v3/core/wallets/deposit-offers)   | Accept or reject incoming Canton transfers, which arrive as two-step offers rather than direct deposits. |
