The problem
Building custody and payouts yourself is months of work — and a hack waiting to happen.
Hot wallets with the keys sitting on a server, manual payouts, gas you top up by hand, no audit trail for a licence. One leaked key and the house is gone. Chainvara gives you the money layer, already built and already hardened, so you ship the game — not the plumbing.
Everything the money side needs
A wallet for every player
Create a deposit address per player on Bitcoin, Ethereum, Solana, Tron and more, with your own player IDs. Deposits are detected and credited the moment they are final, and the sender is screened against sanctions lists.
Instant payouts, under control
Pay winnings in crypto automatically — within per-payout and daily limits, to allowed destinations only, each one approved by your co-signer. No manual signing, no hot wallet left wide open.
A house treasury that can't be drained
Hot and cold vaults, sweeps to cold storage, a policy before every signature and an instant kill switch. A single compromised key or account can never move the house's funds.
Gas and sweeps on autopilot
Deposit addresses are kept topped up with just enough gas to move, and swept to treasury automatically — so you never babysit balances or lose dust to fees.
Rules, approvals and a full audit trail
Limits by amount and destination, approval tiers, velocity caps, and every action logged and reconciled to the chain — ready for a licence review or an audit.
Webhooks and an SDK, not a black box
Signed webhooks for every deposit and payout, a REST API, SDKs in five languages, and a sandbox on test networks. Build it in days, not months.
Proof it works
We ran a full casino on it, end to end.
A player deposit was detected on-chain, swept to treasury automatically, and a withdrawal paid out and confirmed — all through the public API and a co-signer, exactly as a customer would use it. The stack is not a demo; it moves real money today.
Live in three steps
Onboard a player
Call the API at sign-up to create a wallet with your player ID. Funding arrives as a signed webhook.
Run the game
Credit deposits once final, settle bets in your own ledger, and trigger a payout with one API call.
Pay and reconcile
Winnings go out under your rules and your co-signer; deposits sweep to treasury; reports close the books.
Why operators trust it
- Non-custodial: production wallets are 2-of-2 and the full private key never exists in one place — not even we can move funds.
- A co-signer you run and can verify: one file on npm and GitHub with a provenance attestation; it decodes every payout and refuses anything you didn't approve.
- Policy before every signature: per-payout and daily limits, allowed destinations only, and an instant kill switch.
- Audit-ready: every action logged and reconciled to the chain, plus sanctions screening on deposits and payouts.
Runs across 93 mainnets. See the full breakdown on the security page.
