# Security settings

**Audience:** Admin · **App path:** Deployment → **Security**

**Time:** \~10 min

Configure **SecureOwnable** on the Account workspace: owner, timelock, broadcasters, and recovery.

> **Tutorial:** [Configure policy overview](/platform-bloxchain.app/overview-1.md) (Security first in the suggested order)

## Open Security

1. Open your contract tab → **Deployment → Security**.
2. Review the read-only cards: **Owner**, **Timelock**, **Broadcasters**, **Recovery**.

## Change settings (per card)

Each change opens a modal form. Pattern for all: fill fields → **Sign** guard-config meta-tx → **Execute** on-chain.

| Card                   | When to use                                  | Form fields                                                                                  |
| ---------------------- | -------------------------------------------- | -------------------------------------------------------------------------------------------- |
| **Transfer ownership** | Rotate admin owner                           | New owner address (`0x…`)                                                                    |
| **Recovery**           | Assign emergency recovery wallet             | Recovery address (`0x…`) — [test on testnet](/platform-bloxchain.app/recovery.md) only first |
| **Timelock**           | Delay before sensitive approvals finalize    | Timelock duration (seconds)                                                                  |
| **Broadcaster**        | Wallet that submits signed meta-txs on-chain | Broadcaster address (`0x…`); required for meta-tx finalize paths                             |

Protected roles (Owner, Broadcaster, Recovery) are managed here — not under **Deployment → Roles**.

## Verify it worked

* Security panel shows expected owner, timelock seconds, broadcaster list, and recovery address.
* SDK `getSystem()` matches the UI.

## Common issues

* **Meta-tx stuck after sign** — no broadcaster configured, or wrong wallet connected for **Execute**.
* **Cannot sign** — connected wallet lacks permission on guard-config batch (use Owner wallet).

## Next steps

* [Operations](/platform-bloxchain.app/overview-1/operations.md) — register function schemas
* [Meta-transactions](/protocol/meta-transactions.md) · [SecureOwnable](/protocol/secure-ownable.md)
* [How this works](/introduction/operational-model.md) — timelock vs meta-tx paths

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bloxchain.app/platform-bloxchain.app/overview-1/security-settings.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
