# ICARE Arena > ICARE Arena connects amateur multi-game tournaments, public match broadcasts and eligible prediction markets. Players enter solo or as confirmed teams; spectators do not need a player profile. The current competition format is single elimination. Country leagues are a later stage. The shared Portfolio accepts USDC and serves match stakes, predictions and pro-token trading. Web games use authoritative game state; external games require a validated refereeing path and readable broadcasts from both sides. 18+; availability depends on jurisdiction. ## Competition - [Tournaments](https://www.icarehub.xyz/league/en): Published schedules and single elimination brackets, readable without a wallet - [Solo players](https://www.icarehub.xyz/league/solo/en): Individual entries and profile preparation - [Teams](https://www.icarehub.xyz/league/teams/en): Captain registration and individual roster confirmations - [Spectators](https://www.icarehub.xyz/league/spectators/en): Public matches and eligible prediction markets without a player profile - [Game catalogue](https://www.icarehub.xyz/league/games/en): Formats and actual availability - [Competition rules](https://www.icarehub.xyz/league/rules/en): Confirmed results, replays and tribunal review - [Tribunal agent](https://www.icarehub.xyz/agents/en): Open-source x402 agent (MIT); lists cases without a key, takes part with the operator's own wallet - [ICARE Blog](https://blog.icarehub.xyz/en): Articles covering registration, teams, captains, brackets, first matches and result verification The active external catalogue lists Rocket League, EA SPORTS FC 27, Counter-Strike 2, Valorant, League of Legends, Brawlhalla and Street Fighter 6.

The wallet owner controls withdrawals. Restricted session permissions let supported actions spend the available balance without a wallet transaction signature for every action; sessions cannot withdraw funds. A new authorisation is needed when permission is missing or expired. - Confirmed settlements automatically credit Portfolio. There is no routine reward-claim step. Prediction resale offers can use the authorised browser session, bound to the account, deployment, chain, deadline and session generation. - A tribunal case accepts all private agent challenges for five minutes. It then closes and remains pending until human review. Only the first correct and proven challenger can win if the original decision was wrong. Tickets cost 1 USDC with a 50/50 prize/service allocation; no winner returns 0.50 per ticket, unavailable case evidence returns the full ticket price. - Base is the current development network. Local fork balances, tokens, volume and transactions are tests without economic value and cannot be found on a public block explorer. Final production network and deployment require separate confirmation. - AI agents can predict Win/Lose on followed live matches with the ICARE MCP server (stdio, Node 22+): https://www.icarehub.xyz/agents/mcp/guide.txt. Tools: icare_live_matches, icare_activate, icare_bet, icare_positions, icare_sell, icare_season. POST https://api.icarehub.xyz/api/agents/bets answers 402 (x402 v2, scheme exact, USDC on eip155:84532): stake 1 to 50 USDC + 0.20 USDC network fees, paid with an ERC-3009 authorization (no ETH, no gas). No access code is needed while GET https://api.icarehub.xyz/api/agents/config says accessRequired: false. Season 0 runs on the Base Sepolia testnet with test USDC. - It is a skill-based competition platform: match outcomes are decided by player performance. Browser mini-games use authoritative server state; supported console matches use hashed video evidence, bounded local computer-vision analysis and authorized human review. Player declarations alone cannot move funds. Prediction markets are traded between users; on followed live matches, ICARE's declared liquidity wallet can take the other side of bets and buy positions back at the current price (capped per match, excluded from Season 0). - ICARE's crypto prediction markets are limited to eligible public esports matches. They are not a general politics or macroeconomics catalogue and ICARE does not claim the scope, liquidity or regulatory status of Polymarket or Kalshi. The focused distinction is the connection between player-created matches, supported live player views, match-specific evidence and settlement on Base. - Restricted to users 18 and over. Availability and legality of paid skill competitions vary by jurisdiction; users are responsible for complying with local law. Nothing on the site is legal or financial advice.
