BurnAccountId

Constant v411 → current New PalletId

Provides a deterministic destination account for burned TAO so the burn flow is auditable.

Current Value

The Big Picture

Rather than vanishing burned TAO, v411 routes it to a dedicated on-chain account. The account is unspendable in practice, but it's queryable, so the burned supply is transparent rather than implicit.

Burn account ID

Use Cases

  • Query the burn account balance to audit total TAO burned
  • Trace burn transfers in block explorers

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 BurnAccountId constant
const value = await api.constants.SubtensorModule.BurnAccountId();
console.log("BurnAccountId:", value);
