RealPaysFee

Storage Map v385 → v411 Changed in v411

Per-(real, proxy ) pair flag: whether the real account pays for proxy calls between them.

Queried by: walletsdevelopers

The Big Picture

Controls who is charged for a specific (real, proxy) pair. Wallets surfacing proxy actions should check this so users know which account will be debited.

From Chain Metadata

Tracks which (real, delegate) pairs have opted in to the real account paying transaction fees for proxy calls made by the delegate. Existence of an entry means the real account pays; absence means the delegate pays (default).

Purpose & Usage

Purpose

Tracks fee attribution for the (real → proxy) relationship. Entry presence marks real-pays-fee for that pair.

Common Query Patterns

Query by (real, proxy) AccountIds before submitting a proxy call

Query Keys

#	Name	Type	Description
1	real account raw: key1	AccountId	key1 (AccountId) (hex -> SS58)
2	proxy account raw: key2	AccountId	key2 (AccountId) (hex -> SS58)

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 RealPaysFee storage
const key1 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";
const key2 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";

const result = await api.query.Proxy.RealPaysFee.getValue(key1, key2);
console.log("RealPaysFee:", result);
