# fetchSignerRewardsPerTokenSettled

Reads the rewards-per-token value at which a signer-manager's share of one tranche was last settled. Wraps the pox-5 read-only `get-signer-rewards-per-token-settled-for-cycle`, which reads the `signer-rewards-per-token-settled-for-cycle` map.

***

### Usage

```ts
import {
  fetchPoxInfo,
  fetchRewardsPerTokenForCycle,
  fetchSignerRewardsPerTokenSettled,
  fetchSignerSetFirstItem,
  fetchSignerSharesStakedForCycle,
  fetchSignerUnclaimedRewards,
} from '@stacks/bitcoin-staking';

const { rewardCycleId: rewardCycle } = await fetchPoxInfo({ network: 'mainnet' });
const signerManager = await fetchSignerSetFirstItem({ rewardCycle, network: 'mainnet' });

if (signerManager) {
  // STX-only staking tranche. Add bondIndex to read a protocol bond.
  const q = { signerManager, rewardCycle, network: 'mainnet' as const };
  const [shares, rpt, settled, unclaimed] = await Promise.all([
    fetchSignerSharesStakedForCycle(q),
    fetchRewardsPerTokenForCycle({ rewardCycle, network: 'mainnet' }),
    fetchSignerRewardsPerTokenSettled(q),
    fetchSignerUnclaimedRewards(q),
  ]);
  // Same formula as get-earned
  const earned = (shares * (rpt - settled)) / 10n ** 18n + unclaimed;
}
```

#### Notes

* `settle-rewards` sets it to the tranche's current [fetchRewardsPerTokenForCycle](/reference/stacks.js/stacks-bitcoin-staking/fetch/fetchrewardspertokenforcycle.md) value ([settle-rewards](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L2552-L2558)).
* Rewards accrued since the last settlement are `shares * (rewardsPerToken - settled) / 10^18`, the first term of the `get-earned` formula ([compute-earned-rewards](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L2378-L2385)).
* The value is scaled by 10^18 ([`PRECISION`](https://github.com/stacks-network/stacks-core/blob/10474cdec9f9c0bdf05841b58cffc89cdad87a9b/stackslib/src/chainstate/stacks/boot/pox-5.clar#L103)): sats of sBTC per share, times 10^18. A share is one sat in the protocol bond tranche and one micro-STX in the STX-only staking tranche.
* Returns `0n` when the contract has no entry for the inputs.
* A non-2xx response throws an `Error` whose message starts with `Error calling read-only function.` and includes the status code and URL. If the node reports that the call failed, the `Error` message is the node's `cause`.

### Signature

```ts
function fetchSignerRewardsPerTokenSettled(
  opts: {
    signerManager: string;
    rewardCycle: number;
    bondIndex?: number;
  } & NetworkClientParam
): Promise<bigint>;
```

`opts` is a [NetworkClientParam](/reference/stacks.js/stacks-network/network/networkclientparam.md) plus `signerManager`, `rewardCycle` and `bondIndex`.

***

### Returns

`Promise<bigint>`

Resolves to the settled rewards-per-token value, scaled by 10^18.

***

### Parameters

#### opts.signerManager (required)

* **Type**: `string`

Contract principal of the signer-manager, in the form `<address>.<contract-name>`. pox-5 keys signer state by this principal.

#### opts.rewardCycle (required)

* **Type**: `number`

Reward cycle to read.

#### opts.bondIndex (optional)

* **Type**: `number`

Protocol bond index. Set it to read that bond in the protocol bond tranche. Omit it to read the STX-only staking tranche.

#### opts.network (optional)

* **Type**: `StacksNetworkName | StacksNetwork`

The network to query: a name such as `'mainnet'` or `'testnet'`, or a [StacksNetwork](/reference/stacks.js/stacks-network/network/stacksnetwork.md) object. Defaults to `'mainnet'`.

#### opts.client (optional)

* **Type**: `{ baseUrl?: string; fetch?: FetchFn }`

Overrides the API base URL or the `fetch` function, for example to query your own node. Fields you set replace the network's defaults.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.stacks.co/reference/stacks.js/stacks-bitcoin-staking/fetch/fetchsignerrewardspertokensettled.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
