02Wallet
The player's balance lives wherever you want
You pick one of three modes in the dashboard. If you already run a casino, mode 2 keeps everything in a single wallet.
your siteSkull Bookthe balancenetwork call
Mode 1
We hold the wallet
The balance sits in our double-entry ledger. Players deposit and withdraw by Pix inside the iframe, through your gateway, so the money goes in and out of your account. Every day the ledger is checked against the statement.
A good fit if you'll run sports only.
Mode 2
The wallet is yours
Every bet debits your wallet and every payout lands in it. Balance and deposits stay on your own screens. If the debit isn't confirmed, the bet is refused and we send the rollback.
For operators who already run a casino.
Mode 3
You move the balance across
Your platform sends balance to the sports wallet and pulls it back whenever it wants. You don't have to build any API.
To get started without touching the wallet you have today.
03Settlement
Every market pays out by its own rule
On a split Asian line, half the stake goes on each line. That's why a draw can refund one half and lose the other. Period markets use the period score, and a market without a written settlement rule never goes on sale.

Everything a sportsbook needs to operate
From the first odd to the player's withdrawal.
Offer and odds
- Score, clock and stats next to the odds, live and pre-match.
- Live video inside the iframe for e-soccer and other sports.
- Expired odds are refused, and live bets have their own limit.
- If the feed falls behind, the market suspends itself.
Bets
- Singles and multiples, with each leg settled by its own match.
- Legs that depend on each other are blocked in the slip.
- Configurable delay before a live bet is accepted.
- If the connection drops mid-click, the bet isn't placed twice.
Settlement
- 184 markets settled automatically, Asian lines and period results included.
- Half wins, half losses and pushes follow each market's rule.
- If a result changes later, the player gets a notice.
- Every re-settlement records who changed it, when and why.
Player account
- Sign-up inside the widget, or login with the account they already have on your site.
- KYC sent through the iframe and approved by you in the dashboard.
- Deposits by Pix or crypto, depending on the payment provider you connect.

05Day to day
When something goes off script
Capped exposure
You set the limit per event, market and player. When exposure reaches the cap, that market's offer is suspended.
Session signed by you
When a player logs in with their account on your site, your server signs the session with a key that never leaves it.
One alert per change
The alert arrives the moment something changes state, just once. Uncertain withdrawals, stalled webhooks and mismatched reconciliations each have their own.
06Integration
One tag and one endpoint
We take care of the rest. There's a sandbox with test keys and data so you can see it all working first.
Register your domain and key
In the dashboard. The private key stays on your server.
Publish a session endpoint
It confirms who is logged in and signs. Your user base stays with you.
Paste the tag on the page
The widget opens with your colours, your markets and the player's language.
Every money movement sends a signed webhook to your system, retried until you confirm you got it.
