SubnetEmissionEnabledSet

Event v411 → current New #5

Emitted when a subnet 's pool-side emission switch is toggled (chain buys and pool injections).

Useful for: subnet ownersanalyticsdevelopers

The Big Picture

A surgical pause on pool-side emission for a subnet. The subnet's share is still computed, but the chain-buy/injection plumbing is shut off until re-enabled.

Use Cases

Track which subnets currently have pool emission on or off
Alert subnet participants when emission is paused or resumed

From Chain Metadata

Pool-side subnet emission injections and chain buys were enabled or disabled.

Part of: Subnet Emission Control

Triggers

Preconditions

sudo_set_subnet_emission_enabled succeeded

Effects

Postconditions

SubnetEmissionEnabled[netuid] updated

Side Effects

When disabled, pool-side alpha_in/tao_in/excess_tao paths zero out for the subnet
Emission share calculation, owner cut, root proportion, and pending emissions are unaffected

Event Data

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);

// Subscribe to SubnetEmissionEnabledSet events
client.finalizedBlock$.subscribe(async (block) => {
  const events = await api.event.AdminUtils.SubnetEmissionEnabledSet.get(block.hash);
  for (const evt of events) {
    console.log("SubnetEmissionEnabledSet:", evt.payload);
  }
});
