# time-lock

This policy restricts signing to allowed slot ranges. Outside the window, the dWallet cannot sign at all.

Program address (Solana devnet): `2i4bE6s7oc8kkziQETy55SGWQXxwotkpERr9XMv7Q7qs`.

## What it enforces

The program compares the current Solana slot against the configured allowed range(s). A signature is approved only if the slot falls inside an allowed range. The Solana clock is the only time source.

## Configuration

* **Allowed slot range(s)**: the window or windows during which signing is permitted. Use a single future range for a one-time unlock, or recurring ranges for scheduled access.

Changes follow the [policy lifecycle](/hub/andromeda/guides/deploy-policy.md).

## Combine it

* With [`allowlist-destinations`](/hub/andromeda/guides/deploy-policy/allowlist.md): "only these programs, only during this window".
* With [`velocity-guard`](/hub/andromeda/guides/deploy-policy/velocity-guard.md): "only during this window, and at most N per sub-window".

## On-chain guarantees

* Enforced by the authority-holding program; the API cannot sign outside the window.
* Init-authority-hash seeded PDA (no front-running).
* Replay-nonced configuration changes.

## When to use it

* Vesting-style unlocks: funds become movable only after a slot.
* Scheduled operations: a treasury that only acts during a known maintenance window.
* Emergency freezes: set the allowed range to the past to make the wallet immovable until reconfigured.
