Seamless Wallet Integration

Why a seamless wallet casino converts better
A player who has to move money between wallets before every game is a player who may stop. The seamless model removes that step: your wallet holds the balance, and the games ask it what the player can spend.
-
One balance everywhere
The same balance covers slots, live casino, crash games and sportsbook. A win on a slot can be staked on a live table straight away.
-
No transfers for the player
Players never move funds into a game wallet and back. They open a game and play with the money they already see in your cashier.
-
One source of truth
Your wallet stays the single source of truth for reporting. Every bet and win is already in your own ledger when it happens.
For operators running several verticals, this is why a single wallet casino API is usually the model of choice. You can cross-sell a sportsbook player into live casino or a slots player into the sportsbook without asking them to split their money first. Your finance team reconciles one ledger, and your support team answers balance questions from your own records instead of waiting on a supplier.
The seamless wallet API in three calls
The game side talks to your callback URL. Your team answers three kinds of call, and that is the whole money flow.
- 1
Balance check
We ask for the player’s balance before play; you answer only with a confirmed balance.
- 2
Bet and win
Each bet and/or win arrives with its own transaction ID; you apply it and return the balance after the operation.
- 3
Rollback
A failed round is reversed with the original transaction ID; you restore the balance once.
In business terms, the balance check decides whether a round may start, the bet and win call moves the money, and the rollback undoes a round that did not complete. Because every call carries a transaction ID, your wallet always knows which operation it is looking at, and each call can be tested one by one on Stage before any real money moves.
The seamless wallet API works as a common wallet API for the whole catalog: the same three calls arrive whether the player is on a slot, a live table, a crash game or the sportsbook, and from every one of the 160+ studios. Your developers build the callback endpoint once, and every studio you switch on later uses it without new work. That is what keeps the integration short: the wallet is the only money logic your team writes.
Stage and Prod are separate, each with its own login, keys and IP allowlist, so the callback endpoint you point at Stage never sees real-money traffic. Once your wallet answers all three calls correctly and passes acceptance, you receive Prod credentials and switch over on the same prepaid balance.
Rules that keep balances right
Five rules make the model safe for real money. They hold on Stage and Prod alike, so what passes acceptance is exactly what runs live.
- Reject a bet if the player cannot cover it.
- A repeated transaction ID returns the current balance and changes nothing.
- If your balance check fails, no round starts.
- Every call carries an HMAC-SHA256 signature you verify.
- Callback URLs are set per currency.
Each rule protects your margin and your players. Rejecting an uncovered bet means nobody plays on credit. A network retry cannot charge a player twice, because the same transaction ID only returns the balance. A failed balance check stops the round instead of guessing. The signature proves a call really comes from the game side. And per-currency callback URLs keep each currency’s money flow apart in your casino wallet integration.
Seamless or transfer?
Both models use the same catalog, game launch and reporting. They differ in where the money sits and what your team builds.
| Seamless wallet | Transfer wallet | |
|---|---|---|
| Balance location | Your own wallet, the whole time | A separate game wallet you fund and withdraw from |
| Calls you build | One callback endpoint for balance check, bet and win, and rollback, plus signature checks | Transfer calls to move funds in and out; no callbacks |
| Best for | Multi-vertical casinos that want one player balance | Platforms that cannot expose wallet endpoints yet |
We recommend starting on seamless, and you can switch later.
