Sports Betting

Sports betting (Pinwin)

Place and claim decentralized sports bets on Polygon via Pinwin and Azuro, with on-chain execution. The agent fetches prematch and live games from the data-feed, you pick a selection, then it calls Pinwin, signs (and optionally approves USDT), and submits.

Invocation: This skill is invocation-only: the assistant will not use it unless you explicitly ask (e.g. “place a bet with Pinwin”) or use the slash command. That avoids accidental bets.

How to use (OpenClaw)

• Invoke: Use the slash command /sports_betting (or /skill sports-betting) and optionally add your request, e.g. /sports_betting place 5 USDT on the first Premier League game or /sports_betting show my bets.
• Versatility: The assistant should ask you for preferences when not specified: how many games to fetch (first), order (turnover vs startsAt), sport/country/league filters, and which selection you want. It should not suggest or pick a bet unless you explicitly ask for a suggestion (meaningful suggestions would require external data, e.g. news or stats, and could be a separate skill).

When to use

• User wants to place a bet on a game (prematch or live): fetch games → choose a selection → call Pinwin /agent/bet → approve token if needed → sign EIP-712 → POST signature to returned apiUrl.
• User wants to check bet status (pending / resolved / won or lost) or redeem winnings: query the bets subgraph for the bettor’s bets (see Check bet status); when a bet has isRedeemable && !isRedeemed, call Pinwin /agent/claim with those betIds → sign and send the returned transaction with viem.

Prerequisites

Credentials (required env)

• BETTOR_PRIVATE_KEY — Wallet private key (hex) for signing bets and claim transactions. High-sensitivity; do not log or expose. Required for placing and claiming. Use a dedicated betting wallet with minimal funds; do not use your primary wallet.

Optional

• POLYGON_RPC_URL — Polygon RPC endpoint. If unset, the agent uses the default RPC(s) in references/polygon.md (e.g. Pocket Network, PublicNode).

Other

• @azuro-org/dictionaries — required. The subgraph returns only outcomeId and odds; this package is the only way to map them to human-readable market and selection names (e.g. "Total Goals", "Over (2.5)"). See references/dictionaries.md.
• Addresses: relayer, bet token, native gas token (POL), data-feed URL, and bets subgraph URL are in references/polygon.md.
• Balances: The agent can use viem to check POL (gas) and USDT (stake + relayer fee) before placing a bet; if insufficient, inform the user and do not proceed. See references/viem.md.

Flow (place a bet)

0. Optional — check balances: Ensure USDT ≥ stake and POL for gas; exact USDT = stake + payload’s relayerFeeAmount. See references/viem.md.
1. Fetch games – POST data-feed per references/subgraph.md (state Prematch or Live). Get games with conditions (conditionId, outcomes: outcomeId, currentOdds). Names via references/dictionaries.md (getSelectionName({ outcomeId, withPoint: true })). Respect first, orderBy, filters or defaults.
2. Choose selection – Pick one (or more for combo) conditionId + outcomeId from an Active condition. minOdds: single = Math.round(parseFloat(currentOdds) * 1e12); combo = product of each selection’s odds in 12-decimal space (e.g. (odds1×1e12 × odds2×1e12) / 1e12).
3. Call Pinwin – POST https://api.pinwin.xyz/agent/bet with JSON body (see references/api.md). Response: { "encoded": "<base64>" }. Decode: payload = JSON.parse(atob(response.encoded)).
4. Explain to user (before signing) – Display payload: amount and selections from signableClientBetData.bets, relayerFeeAmount, apiUrl, environment, clientData (human-readable names per references/dictionaries.md); then a short summary. See references/api.md.
5. Approval (if needed) – Check bet token’s allowance(bettor, relayer) on Polygon. If < bet amount + relayer fee + 0.2 USDT, sign approve(relayer, bet amount + relayer fee + 0.2 USDT) on the bet token. Approval is bounded to this bet plus a small buffer for security; the agent may need to approve again for the next bet. Addresses: references/polygon.md. Steps: references/viem.md.
6. Verify payload vs user intent – Amount and selections (from bets), clientData.core = claimContract, relayer from references/polygon.md only. See references/api.md. If anything does not match, do not sign and inform the user.
7. Sign and submit – Use viem signTypedData with payload.domain, payload.types, primaryType (see references/api.md), and message: payload.signableClientBetData. Then POST to payload.apiUrl with environment, bettor, betOwner, clientBetData (= payload.apiClientBetData), bettorSignature. The order id is in the POST response: use response.id. If you get an order id, poll until the order settles (see references/api.md): GET {apiBase}/bet/orders/{orderId}. Success = response has txHash; failure = state is Rejected or Canceled (use errorMessage).

Check bet status (before redeem)

To know when a bet is resolved and whether it won or lost, and whether the user can redeem, query the bets subgraph (different from the data-feed). See references/bets-subgraph.md.

1. Query bets – POST a GraphQL query to the bets subgraph URL (Polygon: in references/polygon.md). Query v3Bets with where: { bettor: "<bettor address>" } (address in lowercase). To fetch only bets that can be claimed, add isRedeemable: true to the where clause (see references/bets-subgraph.md). Request at least: betId, status, result, isRedeemable, isRedeemed, amount, payout.
2. Interpret – status = Accepted (pending) | Resolved (settled) | Canceled. When status === Resolved, result = Won or Lost. When isRedeemable === true and isRedeemed === false, the user can claim; collect those bets’ betId values for the claim flow.

Flow (claim)

Only for bets that are resolved (or canceled) and have isRedeemable true and isRedeemed false; get betIds from the bets subgraph (see Check bet status).

1. Call Pinwin – POST https://api.pinwin.xyz/agent/claim with betIds (array of on-chain bet ids) and chain: "polygon". Decode the response encoded payload. Explain to the user in human-readable terms what they are sending: e.g. claiming winnings for bet IDs X, Y; the transaction will go to the Azuro ClientCore contract on Polygon; no value (ETH/POL) is sent. Display the full decoded claim payload (to, chainId, value, and any other keys returned) for transparency.
2. Verify claim contract – Ensure payload.to (lowercase) equals the documented claimContract (ClientCore) for Polygon in references/polygon.md. This is the redeem contract for won/canceled bets, not the Cashout (early-exit) contract. If it does not match, do not send the tx and report the mismatch.
3. Send tx – Use viem sendTransaction with { to: payload.to, data: payload.data, value: 0n, chainId: payload.chainId }. Wait for receipt. Details: references/viem.md.

Example (place a single bet)

After fetching games and choosing one outcome:

POST https://api.pinwin.xyz/agent/bet
{ "amount": 1000000, "minOdds": 1500000000000, "chain": "polygon", "selections": [{ "conditionId": "<from data-feed>", "outcomeId": 21 }] }

Decode response.encoded, sign payload.signableClientBetData with viem signTypedData, then POST to payload.apiUrl with clientBetData and bettorSignature.

Example (claim)

Get betIds from the bets subgraph (e.g. query with isRedeemable: true). Then:

POST https://api.pinwin.xyz/agent/claim
{ "betIds": [215843], "chain": "polygon" }

Decode response.encoded → payload. Display payload to the user; verify payload.to equals the claimContract (ClientCore) in references/polygon.md. Then send tx with viem: sendTransaction({ to: payload.to, data: payload.data, value: 0n, chainId: payload.chainId }). Wait for receipt.

Tools

Required packages: npm install viem @azuro-org/dictionaries. Setup and chain calls: references/viem.md. Dictionaries usage: references/dictionaries.md.

Errors

• Pinwin 4xx/5xx: read error or message in the response body.
• Subgraph: check both HTTP status and data.errors in the JSON body (GraphQL can return 200 with data.errors).
• Chain: tx reverted, insufficient funds — report tx hash.
