+
+On this page you will find information about Aztec.nr dependencies and up-to-date paths for use in your `Nargo.toml`.
+
+## Aztec
+
+```toml
+aztec = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/aztec" }
+```
+
+This is the core Aztec library that is required for every Aztec.nr smart contract.
+
+## Authwit
+
+```toml
+authwit = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/authwit"}
+```
+
+This allows you to use authentication witnesses in your contract. Find more about its usage [here](../resources/common_patterns/authwit.md).
+
+## Address note
+
+```toml
+address_note = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/address-note" }
+```
+
+## Assets
+
+```toml
+assets = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/assets" }
+```
+
+This is a library for utilizing notes that hold addresses. Find it on [GitHub](https://github.com/AztecProtocol/aztec-packages/tree/master/yarn-project/aztec-nr/address-note/src).
+
+## Easy private state
+
+```toml
+easy_private_state = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/easy-private-state" }
+```
+
+This is an abstraction library for using private variables like [`EasyPrivateUint`](https://github.com/AztecProtocol/aztec-packages/blob/6c20b45993ee9cbd319ab8351e2722e0c912f427/yarn-project/aztec-nr/easy-private-state/src/easy_private_state.nr#L17).
+
+## Safe math
+
+```toml
+safe_math = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/safe-math" }
+```
+
+This is a library for safe arithmetic, similar to OpenZeppelin's safe math library. Find it on [GitHub](https://github.com/AztecProtocol/aztec-packages/tree/master/yarn-project/aztec-nr/safe-math).
+
+## Value note
+
+```toml
+value_note = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/value-note" }
+```
+
+This is a library for a note that stores one arbitrary value. You can see an example of how it might be used in the [token contract tutorial](../../tutorials/writing_token_contract.md).

+title: Aztec.nr Errors
+---
+
+This section contains some errors that you may encounter when writing and compiling contracts in Aztec.nr. If you run into an error that is not listed here, please [create an issue](https://github.com/AztecProtocol/aztec-packages/issues/new).
+
+#### `Aztec dependency not found. Please add aztec as a dependency in your Nargo.toml`
+
+All smart contracts written in Aztec.nr need the `aztec` dependency. In your `Nargo.toml` under `[dependencies]`, add this:
+
+```toml
+aztec = { git="https://github.com/AztecProtocol/aztec-packages/", tag="#include_aztec_version", directory="yarn-project/aztec-nr/aztec" }
+```
+
+You can learn more about dependencies and their paths [here](../contracts/resources/dependencies.md).
+
+#### `compute_note_hash_and_nullifier function not found. Define it in your contract`
+
+Any smart contract that utilizes private varibles must include a [`compute_note_hash_and_nullifier`](https://github.com/AztecProtocol/aztec-packages/blob/6c20b45993ee9cbd319ab8351e2722e0c912f427/yarn-project/aztec-nr/aztec/src/note/utils.nr#L69) function to allow the PXE to process encrypted events.
+
+This is an example of this function in the token contract:
+
+#include_code compute_note_hash_and_nullifier yarn-project/noir-contracts/src/contracts/token_contract/src/main.nr rust
+
+This error may also show if the `compute_note_hash_and_nullifier` function is not correct or sits outside of the contract.
+
+#### `backend has encountered an error`
+
+This is likely due to a version mismatch or bad install of barretenberg. Try [reinstalling nargo](../cli/updating.md) or uninstalling barretenberg:
+
+```bash
+nargo backend uninstall acvm-backend-barretenberg
+```
+
+It will then reinstall when you compile.
+
+#### `Oracle callback {} not found` & `Oracle callback pedersenHash not found`
+
+This can occasionally happen when there are breaking releases. Make sure that your dependencies in `Nargo.toml` are [updated to the latest release](../contracts/resources/dependencies.md).
+
+#### `error: Failed constraint: 'Public state writes only supported in public functions`
+
+Reading and writing to public state from private functions is currently not supported.
+This is because public values may change before the private function execution is posted on-chain.
+
+This may change in future versions.
+
+#### `Simulation error: Assertion failed:...`
+
+This is an assertion error that is thrown when a condition is not met.
+
+To address the error. find the line in the contract that is throwing the error and investigate why the condition is not met.
+
+#### `Unknown contract 0x0: add it to PXE by calling server.addContracts(...)`
+
+This error occurs when you are trying to interact with a smart contract via an Private Execution Environment (PXE) that does not have the necessary information to execute a transaction.
+
+To execute a transaction, the PXE needs to know the complete address of a contract, portal address (if portal is used) and contract artifacts.
+
+To address the error, add the contract to the PXE by calling `server.addContracts(...)`.
+
+`Simulation error: No public key registered for address 0x0. Register it by calling pxe.registerRecipient(...) or pxe.registerAccount(...)`
+
+This error occurs when your contract is trying to get a public key via the `get_public_key` oracle call, but the PXE does not have the Complete Address (Complete Address contains the public key).
+
+Your contract typically needs a note recipient's public key when it wants to send a note to because the public key is used to encrypt notes.
+
+:::info
+Manually adding the recipient to the PXE should not be required in case the recipient contract has already been deployed and the PXE is fully synced.
+This is because this information is submitted on-chain when the recipient contract is deployed.
+:::
+
+#### `Could not process note because of "Error: Unknown account.". Skipping note...`
+
+This error occurs when your contract is trying to get a secret via the `get_secret` oracle call, but the PXE does not have the secret for the public key.
+
+This error might occur when you register an account only as a recipient and not as an account.
+To address the error, register the account by calling `server.registerAccount(...)`.
