Constant v154 → current Option

The amount reserved when calling extend(). Can differ from EnterDepositAmount to create different economic incentives for extensions vs initial activation.

Current Value

The Big Picture

Extensions also require deposits. This prevents indefinite safe-mode without ongoing economic commitment. Each extension is tracked and released independently.

From Chain Metadata

The amount that will be reserved upon calling [`Pallet::extend`]. `None` disallows permissionlessly extending the safe-mode and is a sane default.

Use Cases

  • Budget for extending safe-mode
  • Plan multiple extensions

Code Examples

import { createClient, Binary } from "polkadot-api";
import { getWsProvider } from "polkadot-api/ws";
import { sub } from "@polkadot-api/descriptors"; // generated by: npx papi add sub -w wss://entrypoint-finney.opentensor.ai:443

const client = createClient(getWsProvider("wss://entrypoint-finney.opentensor.ai:443"));
const api = client.getTypedApi(sub);

// Query ExtendDepositAmount constant
const value = await api.constants.SafeMode.ExtendDepositAmount();
console.log("ExtendDepositAmount:", value);
