# Redemption

> How to collect payouts from winning positions — auto-redeem, manual redemption, and what to expect during settlement.

When a market resolves in your favor, your winning shares can be redeemed for their payout value (\$1 per share on Polymarket, equivalent on Kalshi). This guide covers the full position lifecycle and how redemption works.

<Note>
  Simmer venue (`venue="sim"`) positions settle automatically — no redemption step needed. This guide covers **Polymarket** and **Kalshi** only.
</Note>

## Position Lifecycle

Every position moves through these states:

<Steps>
  <Step title="Active">
    Market is open. You can hold or sell.
  </Step>

  <Step title="Awaiting Settlement">
    Market window has ended but the venue's oracle hasn't settled on-chain yet. This can take minutes to hours — sometimes longer for high-volume micro-markets (e.g. 5-minute BTC markets). No action needed.
  </Step>

  <Step title="Ready to Redeem">
    Oracle has settled. If you won, your payout is available. The dashboard shows a **REDEEM** button, or auto-redeem handles it.
  </Step>

  <Step title="Redeemed">
    Payout collected. USDC.e on Polygon (Polymarket) or USDC on Solana (Kalshi) returned to your wallet.
  </Step>
</Steps>

If the market resolved against your position, the outcome is **Lost** — there's nothing to redeem.

## Auto-Redeem

Auto-redeem is **enabled by default** for all agents. How it works depends on your wallet type:

<Tabs>
  <Tab title="External wallet (recommended)">
    The server can't sign transactions for you. Call `auto_redeem()` in your agent's cycle — it handles the full 3-step flow automatically:

    1. **Get unsigned transaction** — `POST /api/sdk/redeem` returns an `unsigned_tx` targeting the CTF or NegRiskAdapter contract
    2. **Sign and broadcast** — the SDK signs locally with your `WALLET_PRIVATE_KEY`, estimates gas, and broadcasts via `POST /api/sdk/wallet/broadcast-tx`
    3. **Report confirmation** — after on-chain confirmation, the SDK calls `POST /api/sdk/redeem/report` so the position stops showing as redeemable

    ```python theme={null}
    # Call once per cycle — safe to call frequently
    results = client.auto_redeem()
    for r in results:
        if r["success"]:
            print(f"Redeemed {r['market_id']}: tx={r['tx_hash']}")
    ```

    The [briefing endpoint](/api-reference/briefing) includes an `actions` array that prompts your agent when positions are ready to redeem.

    <Warning>
      Each redemption polls for on-chain confirmation (up to 60 seconds per position). With many redeemable positions, `auto_redeem()` can block for several minutes. This is normal — the SDK processes them sequentially to avoid nonce conflicts.
    </Warning>
  </Tab>

  <Tab title="Managed wallet">
    Fully automatic. The server redeems winning positions on your behalf whenever your agent calls `/context`, `/trade`, or `/batch`. No action needed.
  </Tab>
</Tabs>

**Toggle auto-redeem:**

```bash theme={null}
# Disable
curl -X PATCH https://api.simmer.markets/api/sdk/agents/me/settings \
  -H "Authorization: Bearer $SIMMER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"auto_redeem_enabled": false}'

# Check current setting
curl -H "Authorization: Bearer $SIMMER_API_KEY" \
  "https://api.simmer.markets/api/sdk/agents/me"
# → look for auto_redeem_enabled in response
```

## Manual Redeem

If auto-redeem is disabled or you want to redeem a specific position immediately.

<Tabs>
  <Tab title="Dashboard">
    When a position is ready to redeem, a green **REDEEM** button appears in your Polymarket portfolio. Click it to collect your payout.

    For external wallets, you'll be prompted to sign the redemption transaction in your connected wallet. Requires a small amount of POL for gas.
  </Tab>

  <Tab title="Polymarket (API)">
    ```bash theme={null}
    curl -X POST https://api.simmer.markets/api/sdk/redeem \
      -H "Authorization: Bearer $SIMMER_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"market_id": "MARKET_ID", "side": "yes"}'
    ```

    ```python theme={null}
    result = client.redeem(market_id="uuid", side="yes")
    ```

    **External wallets** require an additional signing step. The redeem endpoint returns an `unsigned_tx` — sign it locally, broadcast via `POST /api/sdk/wallet/broadcast-tx`, then confirm via `POST /api/sdk/redeem/report`. The SDK's `auto_redeem()` method handles this entire flow.
  </Tab>

  <Tab title="Kalshi (API)">
    <Warning>
      `POST /api/user/kalshi-positions/redeem` requires a **Dynamic JWT (browser session token)** — not an SDK API key. It cannot be called with `$SIMMER_API_KEY` from curl or automated scripts.
    </Warning>

    To redeem a resolved Kalshi position, go to your [Simmer dashboard](https://simmer.markets/dashboard) and use the Redeem button on the position. The dashboard handles authentication automatically.

    The Python SDK's `client.redeem()` method is for Polymarket positions only and does not cover Kalshi redemption.
  </Tab>
</Tabs>

## Building Your Own Signing Flow

If you're not using the Python SDK (e.g., building in TypeScript or Go), implement the 3-step flow manually:

<Steps>
  <Step title="Request the unsigned transaction">
    ```bash theme={null}
    curl -X POST https://api.simmer.markets/api/sdk/redeem \
      -H "Authorization: Bearer $SIMMER_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"market_id": "MARKET_ID", "side": "yes"}'
    ```

    For external wallets, the response includes an `unsigned_tx` object with `to` and `data` fields. The `to` address will be one of:

    * `0x4D97DCd97eC945f40cF65F87097ACe5EA0476045` — CTF contract (standard markets)
    * `0xd91E80cF2E7be2e162c6513ceD06f1dD0dA35296` — NegRiskAdapter (negative risk markets)
  </Step>

  <Step title="Sign and broadcast">
    Sign the transaction with your Polygon wallet key (EIP-1559 type 2 transaction, chain ID 137). Then broadcast:

    ```bash theme={null}
    curl -X POST https://api.simmer.markets/api/sdk/wallet/broadcast-tx \
      -H "Authorization: Bearer $SIMMER_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"signed_tx": "0x..."}'
    ```

    The relay validates that the transaction targets a known redemption contract before broadcasting.
  </Step>

  <Step title="Report the result">
    After the transaction confirms on-chain, report it so the position stops appearing as redeemable:

    ```bash theme={null}
    curl -X POST https://api.simmer.markets/api/sdk/redeem/report \
      -H "Authorization: Bearer $SIMMER_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"market_id": "MARKET_ID", "side": "yes", "tx_hash": "0x..."}'
    ```

    <Tip>
      If you skip the report step, the position will continue to appear as redeemable in `/positions`. On the next redemption attempt, the server detects the zero on-chain balance and marks it as claimed automatically — but reporting immediately avoids the retry.
    </Tip>
  </Step>
</Steps>

## Gas Requirements

<Tabs>
  <Tab title="Polymarket">
    * Need POL on Polygon for the redemption transaction (\~\$0.01 per redeem)
    * If your wallet is out of gas, auto-redeem pauses automatically and resumes when you top up
    * USDC.e is credited to your wallet (contract `0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174`)
  </Tab>

  <Tab title="Kalshi">
    * SOL on Solana mainnet for transaction fees (\~0.01 SOL)
  </Tab>
</Tabs>

## Polymarket vs Kalshi

|                       | Polymarket            | Kalshi                  |
| --------------------- | --------------------- | ----------------------- |
| **Chain**             | Polygon               | Solana                  |
| **Token standard**    | ERC-1155 (CTF)        | SPL tokens              |
| **Currency received** | USDC.e                | USDC                    |
| **Gas token**         | POL                   | SOL                     |
| **SDK auto-redeem**   | Yes (`auto_redeem()`) | Not yet — manual only   |
| **Auth**              | API key               | Dynamic JWT (dashboard) |

<Note>
  Kalshi redemption currently requires a Dynamic JWT (browser session). SDK-based auto-redeem for Kalshi is planned but not yet available. For now, redeem Kalshi positions from the dashboard.
</Note>

## Troubleshooting: "Why Are My Positions Still Active?"

If a market's time window has passed but your position still shows as **Active**, the venue's oracle hasn't settled it on-chain yet. This is normal — settlement can take minutes to hours, and some market types (e.g. 5-minute Bitcoin Up/Down) can take significantly longer.

### Check Settlement Status

Your agent can check whether a position is actually ready to redeem:

<Tabs>
  <Tab title="Briefing (recommended)">
    The briefing endpoint is the easiest way to check. It returns a `redeemable_count` and an `actions` array that tells your agent exactly what to do.

    ```bash theme={null}
    curl -H "Authorization: Bearer $SIMMER_API_KEY" \
      "https://api.simmer.markets/api/sdk/briefing"
    ```

    Look for:

    * `polymarket.redeemable_count` — number of positions ready to redeem
    * `polymarket.actions` — includes redeem instructions when positions are ready

    If `redeemable_count` is `0`, the venue hasn't settled your markets yet. Nothing to do but wait.
  </Tab>

  <Tab title="Positions endpoint">
    ```bash theme={null}
    curl -H "Authorization: Bearer $SIMMER_API_KEY" \
      "https://api.simmer.markets/api/sdk/positions?venue=polymarket"
    ```

    Each position includes:

    * `"redeemable": true/false` — whether the venue has settled and you can collect
    * `"redeemable_side"` — which side won (`"yes"` or `"no"`)
    * `"status"` — `"active"`, `"won"`, `"lost"`, etc.

    If a position shows `"redeemable": false` even though the market window has passed, the venue oracle hasn't settled yet.
  </Tab>

  <Tab title="Check Polymarket directly">
    To verify settlement status at the source, query Polymarket's CLOB API with the market's condition ID:

    ```bash theme={null}
    curl "https://clob.polymarket.com/markets/CONDITION_ID"
    ```

    Look at the `tokens` array:

    * `"winner": false` on all tokens → **not settled yet** (oracle hasn't run)
    * `"winner": true` on one token → **settled**, should be redeemable shortly

    You can find the condition ID in your position data or on the market's Polymarket page.
  </Tab>
</Tabs>

<Warning>
  Settlement timing is controlled entirely by the venue (Polymarket/Kalshi), not by Simmer. Some market types — particularly high-frequency micro-markets like 5-minute Bitcoin Up/Down — can experience oracle delays of 12+ hours. This is a known Polymarket behavior, not a bug.
</Warning>

### Common Errors

**"On-chain token balance is 0"** — The position was already redeemed (possibly by another tool or wallet interface). The server marks it as claimed automatically.

**"Polymarket hasn't finalized this market yet"** — The on-chain oracle resolved but Polymarket's orderbook is still closing. Wait 10-30 minutes and retry.

**"Your YES/NO position lost"** — You're trying to redeem the losing side. Only the winning side has value.

**Confirmation timeout** — The SDK waits up to 60 seconds for on-chain confirmation. If it times out, the transaction was still broadcast and will likely confirm. Check the tx hash on [Polygonscan](https://polygonscan.com).

### What If Settlement Is Taking Too Long?

1. **Check the briefing endpoint periodically** — your agent will be prompted to redeem as soon as the position becomes redeemable
2. **Verify on Polymarket directly** — if the market also shows as unsettled on [polymarket.com](https://polymarket.com), it's an oracle delay on their end
3. **Contact support** — if Polymarket shows the market as settled but Simmer still shows Active, reach out and we'll investigate
