Platform Information & Legal
Everything you need to know about SumoBets: how it works, security, pricing, help resources, and legal policies.
Last Updated: February 5, 2025
How It Works
SumoBets is a custodial betting platform built on the Solana blockchain. Bet on live sumo matches with pool-based odds; deposits and withdrawals are USDC on Solana.
Create Account
Sign up with email or Google. Your balance is held by SumoBets (custodial), so there's no wallet to set up to start.
Deposit USDC
Get your unique Solana deposit address and transfer USDC from any wallet or exchange. It's credited once the transfer is finalized on Solana.
Place Bets
Choose your fighter and bet amount. Odds update as the pool changes. Odds shown use the current pools. Your payout depends on the final pools when betting closes.
Win & Withdraw
Winnings are credited when an admin resolves the match. Withdrawals are sent on-chain from our hot wallet to your Solana wallet.
Custodial Wallet System
You don't need your own wallet to start betting. Your balance is held by SumoBets and recorded in our database. You get a unique Solana deposit address for adding funds, and you can withdraw to any Solana wallet that has a USDC token account, within the withdrawal limits listed in the Help Center.
Pool-Based Odds (Not House Odds)
Odds are determined by the actual money in the betting pool, not set by SumoBets:
Odds = 0.97 × Total Pool ÷ Fighter Pool
The 3% fee is taken once, when you place a bet; winners split the whole pool in proportion to their stake. For example, if $1,000 is bet on Fighter A and $500 on Fighter B, Fighter B shows 2.91x (0.97 × $1,500 ÷ $500, rounded down): a $10 bet would return $29.10. If nobody bets on one side, every stake is refunded in full, fee included.
Blockchain Integration
Deposits and withdrawals are USDC (a stablecoin pegged to the US dollar) transfers on Solana, so each one has a public transaction you can look up. Bets and balances themselves are recorded by SumoBets, not on-chain.
Withdrawals
When you request a withdrawal, we check your address, balance and limits, deduct the amount, and queue it. A background worker then sends the USDC on-chain from our hot wallet. If the transfer fails, the amount is returned to your balance. No processing time is guaranteed.
Pricing (3% Platform Fee)
SumoBets charges a 3% platform fee on each bet, taken when the bet is placed. There are no other SumoBets fees.
Our Fee Structure
- ✓Platform Fee: 3% on all bets (collected when you place a bet)
- ✓Withdrawal Fee: FREE (SumoBets pays the Solana network fee for sending withdrawals)
- ✓Deposit Fee: FREE (your wallet pays the usual Solana network fee to send)
- ✓Bet Limits: Loading the current limits…
- ✓Withdrawal Limits: Loading the current limits…
When Is the Fee Collected?
The 3% platform fee is deducted when you place a bet, not when you withdraw. Your stake and the fee are known when you bet; your payout depends on the final pools when betting closes. If you bet $100, we collect $3 as our fee, and $97 goes into the betting pool.
Why 3%?
Our 3% fee funds platform operations, development, security, and server costs. Because odds come from the pool rather than being set by us, the fee is the only thing SumoBets takes from a bet. If a match is a no-contest or one-sided, the fee is refunded along with the stake.
No Hidden Fees: What you see is what you get. We will never add surprise charges, processing fees, or account maintenance fees. The 3% platform fee is all we take.
Security
This page describes how SumoBets protects accounts and funds today.
Custodial Wallet Architecture
SumoBets is custodial: we hold the keys on your behalf. The keys for per-user deposit addresses are encrypted with AES-256-GCM before they are stored. Withdrawals are sent from a separate platform hot wallet whose key is kept only on our server. Balances, bets and settlement are recorded in our database; only deposits and withdrawals happen on Solana.
Encryption Standards
AES-256-GCM Encryption
Deposit-address private keys are encrypted using AES-256-GCM, with a unique nonce for each encryption.
Argon2 Password Hashing
User passwords are hashed using Argon2, the winner of the Password Hashing Competition, which makes stolen password hashes expensive to brute-force.
Password Requirements
We enforce strong password requirements to protect your account:
- Minimum 12 characters
- At least one uppercase letter
- At least one lowercase letter
- At least one number
- At least one special character
Authentication Security
We use JWT (JSON Web Tokens) stored in HttpOnly, Secure cookies with SameSite=Lax protection. This means:
- HttpOnly: JavaScript cannot access your authentication token, preventing XSS attacks
- Secure: Token only transmitted over HTTPS connections
- SameSite=Lax: Protection against CSRF attacks
- 7-day expiration: Tokens automatically expire after 7 days for security
Transaction Security
Row-Level Locking
Withdrawal requests use PostgreSQL row-level locking to prevent double-spending. Only one withdrawal can be processed at a time per user.
Address Validation
All Solana addresses are validated before processing withdrawals. Invalid addresses are rejected immediately to prevent loss of funds.
Amount Bounds Checking
Bet and withdrawal amounts are checked on the server against the configured limits, including a rolling 24-hour withdrawal cap. Loading the current limits… Loading the current limits…
Admin Protections
Administrative operations (like resolving matches) are protected by:
- RequireAdmin middleware: Only verified admin accounts can perform sensitive operations
- Audit logging: All admin actions are logged with timestamps and user IDs
- Balance reconciliation: Admins can run a check comparing user balances with the funds held on-chain
Data Security
Your data is protected through multiple layers:
- TLS/SSL encryption for all data in transit
- No third-party data sharing (except when legally required)
- Access controls limiting who can view sensitive data
Blockchain Transparency
All transactions happen on the Solana blockchain, which provides a transparent, immutable record. You can verify any deposit or withdrawal using a Solana block explorer like solscan.io. Your transaction signatures are available in your transaction history.
Important: While we implement extensive security measures, cryptocurrency carries inherent risks. Never bet more than you can afford to lose. Keep your account password secure and never share it with anyone.
API Documentation
Note: External API access is not currently available. The API is used internally by our web platform. When we open public API access in the future, we'll provide API keys and full documentation.
For transparency, here are the main API endpoints our platform uses. These details help you understand how the system works under the hood.
Public Endpoints
/api/auth/registerCreate a new user account with email and password.
Request: email, password, display_name (optional)
/api/auth/loginAuthenticate with email and password. Returns JWT token in HttpOnly cookie.
Request: email, password
/api/betting/matchesList all betting matches. Optionally filter by status (open, closed, resolved).
Query params: status (optional)
Authenticated Endpoints
These endpoints require authentication via JWT cookie (obtained from login).
/api/betting/placePlace a bet on a match.
Request: match_id, fighter_choice (fighter_a or fighter_b), amount_usdc
/api/wallet/balanceGet current USDC balance for authenticated user.
/api/wallet/deposit-addressGet unique Solana address for depositing USDC.
/api/wallet/withdrawRequest withdrawal to external Solana wallet.
Request: destination_address, amount_usdc
Authentication Method
Authentication uses JWT tokens stored in HttpOnly secure cookies. When you log in, the server sets a cookie named sumo_bets_token that contains your authentication token. This cookie is automatically sent with each request.
Response Formats
All API responses are in JSON format. Successful responses include the requested data. Error responses include an error message and appropriate HTTP status code.
{
"success": true,
"data": { ... }
}{
"error": "Error message here"
}Rate Limiting
Rate limiting details will be published when public API access is available. Currently, the web platform has reasonable usage limits to prevent abuse.
WebSocket Chat Connection
The live chat feature uses WebSocket for real-time messaging:
wss://sumobets.app/api/chat/ws
The connection is authenticated with your session cookie, and only connections from the SumoBets site are accepted. Messages are broadcast to all connected users in real time.
Future: Public API Access
When we open public API access, we'll provide:
- API keys for authentication
- Webhooks for match result notifications
- Full OpenAPI/Swagger documentation
- Rate limiting details and quotas
- SDK libraries for popular languages
Help Center
Find answers to common questions and learn how to use SumoBets effectively.
Getting Started
- Create an account with your email and a strong password (or use Google OAuth)
- Get your unique USDC deposit address from the Wallet page
- Transfer USDC from any wallet or exchange to your deposit address
- Wait for the deposit to be credited (once the transfer is finalized on Solana)
- Start betting on live matches!
Account Management
How do I reset my password?
Password reset feature is coming soon. For now, contact support at sumobets@proton.me if you need help accessing your account.
Can I change my display name?
Display name customization is coming in a future update. Currently, your display name is set during registration.
Where can I view my transaction history?
Visit the "My Bets" page to see all your bets and their outcomes. The Wallet page shows your deposit and withdrawal history.
Deposits
What's the minimum deposit?
SumoBets doesn't set a minimum deposit, but a deposit address holding less than 0.01 USDC isn't credited until more arrives and the total reaches 0.01 USDC. Bets have their own limits: Loading the current limits…
How long do deposits take?
Your deposit is credited once the transfer is finalized on Solana and our deposit monitor has picked it up. Your balance updates automatically; there is no fixed time.
What cryptocurrencies do you accept?
We only accept USDC on Solana. USDC is a stablecoin pegged to the US dollar, so $1 USDC = $1 USD. You can buy USDC on exchanges like Coinbase, Binance, or Kraken.
My deposit isn't showing up. What should I do?
Give it a little time to be finalized and picked up. If it still doesn't appear, verify you sent USDC (not SOL or another token) to your correct deposit address on the Solana network. Contact support if issues persist.
Withdrawals
How fast are withdrawals?
Withdrawals are queued and sent on-chain from our hot wallet. There is no guaranteed time; your transaction history shows the status and, once sent, the transaction signature.
What's the minimum withdrawal?
Loading the current limits…
What's the maximum withdrawal?
Loading the current limits…
Do I need to provide a Solana address?
Yes. You'll need a Solana wallet address to receive withdrawals. Popular Solana wallets include Phantom, Solflare, and Coinbase Wallet. Make sure you provide a valid Solana address, not an Ethereum or Bitcoin address.
My withdrawal failed. What happened?
Common reasons: an invalid Solana address, a destination wallet without a USDC token account, insufficient balance, or an amount outside the limits. A failed withdrawal is returned to your balance.
Placing Bets
How do I place a bet?
Go to the live matches list, choose a match, select your fighter, enter your bet amount, review the odds, and confirm. Bets are final, and you'll see yours in "My Bets".
What are the minimum and maximum bets?
Loading the current limits… Large bets move the odds for that match.
Can I bet after the match starts?
No. Betting closes shortly before the match starts (each match shows its exact closing time). This ensures fairness and prevents betting on known outcomes.
Can I cancel a bet?
No. Bets are final once placed. Make sure you're confident before confirming.
Understanding Odds
How are odds calculated?
Odds are determined by the betting pool, not by us. The formula is:
Odds = 0.97 × Total Pool ÷ Fighter Pool
The odds shown are what each 1 USDC you bet returns if your fighter wins at the current pools, after our 3% fee, rounded down. The fee is taken once, when you place the bet; winners split the whole pool in proportion to their stake after the fee. If $1,000 is bet on Fighter A and $500 on Fighter B, Fighter B shows 2.91x: a $10 bet would return $29.10. If nobody bets on one side, every stake is refunded in full, fee included.
Do odds change after I place my bet?
Odds shown use the current pools. Your payout depends on the final pools when betting closes. If other people bet after you, the pools change and so does your payout.
Why do pool-based odds matter?
With pool-based odds you bet against other users, not against SumoBets. The only thing SumoBets takes is the 3% fee on each bet.
Claiming Winnings
How do I claim my winnings?
You don't need to do anything! Winnings are credited to your balance automatically when an admin resolves the match, and show up in your balance and My Bets.
When are matches resolved?
An admin resolves each match after the official result is known. There is no fixed time.
Troubleshooting
Deposit not showing?
Deposits are credited once finalized on Solana. Verify you sent USDC on Solana (not another network). Check the transaction on solscan.io.
Withdrawal failed?
Check that your Solana address is correct and has a USDC token account, and that you have enough balance. Loading the current limits…
Can't place a bet?
Check that betting on the match is still open and your balance is sufficient. Loading the current limits…
Login issues?
Double-check your email and password. Clear browser cache and cookies. Try a different browser. If issues persist, contact support.

Frequently Asked Questions
Quick answers to the most common questions about SumoBets.
How do withdrawals work?
Your withdrawal is queued and then sent on-chain as USDC from our hot wallet to the Solana address you enter. The destination wallet must already have a USDC token account; if a withdrawal fails, the amount is returned to your balance. Your transaction history shows the status and, once sent, the transaction signature.
How are odds determined?
Our odds are pool-based, not house-set. The odds shown are what each 1 USDC you bet returns at the current pools, after our 3% fee (taken once, when you bet): 0.97 × Total Pool ÷ Fighter Pool, rounded down. If $1,000 is bet on Fighter A and $500 on Fighter B, Fighter B shows 2.91x: a $10 bet would return $29.10. If nobody bets on one side, every stake is refunded in full. Odds shown use the current pools. Your payout depends on the final pools when betting closes. You're betting against other users, not against us.
What are the fees?
A 3% platform fee on each bet, taken when you place the bet; the rest of your stake goes into the pool. SumoBets charges no deposit or withdrawal fees and pays the Solana network fee for withdrawals. When you deposit, your own wallet pays the usual Solana network fee for sending.
Is my money safe?
SumoBets is custodial: your balance is held by SumoBets and recorded in our database, not in a smart contract. Deposit-address keys are encrypted with AES-256-GCM, passwords are hashed with Argon2, sessions use HttpOnly cookies, and admin actions are audit-logged. Holding funds with any custodial service carries risk, so never deposit more than you can afford to lose.
Do I need crypto knowledge?
Only a little. You need USDC (a stablecoin worth about $1) on the Solana network: buy it on an exchange such as Coinbase or Binance and send it to your deposit address, choosing Solana as the network. Once it's credited, betting happens on our site with no blockchain steps. To withdraw, you need a Solana wallet that already has a USDC token account.
What happens if a match is cancelled?
If a match is declared a no-contest, or nobody bet on one of the two sides, every bettor gets their full stake back, including the 3% fee.
Can I bet after the match starts?
No. Betting closes shortly before the match starts, or earlier if an admin set an earlier close time for that match. Each match shows when its betting closes. The server decides whether a bet is in time.
What are the minimum and maximum bets?
Loading the current limits… Large bets move the odds for that match, since odds come from the pool: the more is bet on a fighter, the lower that fighter's odds.
How do I verify a transaction?
Every deposit and withdrawal happens on the Solana blockchain, which is public and transparent. You can verify any transaction using your transaction signature on Solana block explorers like solscan.io. Your transaction history shows all signatures.
Can I cancel a bet?
No. Bets are final once placed and cannot be cancelled. This is necessary for the integrity of the betting pool. Make sure you're confident in your bet before confirming.
What if I forget my password?
Password reset functionality is coming soon. For now, contact support at sumobets@proton.me with your registered email and we'll help you regain access to your account. Make sure to use a strong, memorable password when you create your account.
Do you offer account verification or KYC?
Currently, we don't require KYC (Know Your Customer) verification. You can sign up and bet anonymously with just an email. However, this may change in the future if required by regulations.
What are the withdrawal limits?
Loading the current limits…
How is the odds calculation fair?
Because odds are determined by the actual money in the pool, not by us. If Fighter A has more money bet on them, their odds decrease (lower payout multiplier). If Fighter B has less money, their odds increase (higher multiplier). SumoBets doesn't set the odds; its only charge is the 3% fee. Odds shown use the current pools. Your payout depends on the final pools when betting closes.
What happens to my bet if I win?
Winnings are credited to your balance automatically when an admin resolves the match. You don't need to claim anything, and you can withdraw them like any other balance.
Can I watch matches on the platform?
We embed a sumo stream from Twitch on the site, so when the channel is live you can watch and bet on the same page. SumoBets doesn't run the stream.

Responsible Gambling
SumoBets is committed to promoting responsible gambling. Betting should be entertainment, not a way to make money or solve financial problems.
⚠️ Important: Only Bet What You Can Afford to Lose
Betting carries financial risk. Never bet money you need for rent, bills, food, or other essentials. Set a budget before you start and stick to it.
Age Verification
You must be at least 18 years old (or the age of majority in your jurisdiction) to use SumoBets. Gambling by minors is illegal and strictly prohibited. If we discover an underage user, we will immediately close the account and return any remaining balance.
Self-Assessment: Do You Have a Problem?
Ask yourself these questions honestly:
- Are you betting more than you can afford to lose?
- Have you tried to stop or cut back but couldn't?
- Are you chasing losses (betting more to win back what you lost)?
- Are you lying to friends or family about your gambling?
- Is gambling affecting your work, relationships, or mental health?
- Are you borrowing money or selling possessions to fund gambling?
- Do you feel anxious, depressed, or guilty about gambling?
- Are you neglecting responsibilities to gamble?
If you answered "yes" to any of these questions, you may have a gambling problem. Please seek help immediately.
