# FAQ Answers to the most common questions about onchain.cc. *** ## General ### Is onchain.cc safe to use? Yes. onchain.cc is built and backed by Bitso — Latin America's largest licensed crypto exchange — which means it operates under institutional-grade compliance standards. The platform is self-custodial, meaning you always control your own wallet and private keys. onchain.cc never holds your funds, never has access to your wallet, and cannot move your assets on your behalf. ### What wallet do I need to get started? onchain.cc supports both Solana and EVM wallets. You can connect with Solana wallets (**Phantom, Backpack, Solflare**) or EVM wallets (**MetaMask, Rabby, or any WalletConnect-compatible app**) depending on which chain you want to trade on. You can also sign in with an email address or Google account — onchain.cc uses Privy as its authentication layer, which creates a non-custodial embedded wallet for you automatically. No matter which method you choose, you remain in full control of your assets. ### Is onchain.cc available in my country? onchain.cc is available in most countries, but access may be restricted in certain jurisdictions based on local regulations. The platform checks your location at login. If access is restricted in your region, you will see a notice at that point. Check [onchain.cc](https://onchain.cc) directly for the most current availability information. *** ## Trading ### What are the fees on onchain.cc? onchain.cc charges a flat **0.15% platform fee** on every trade. This is deducted from the output amount — there are no hidden charges, no tiered structures, and no tokens required to access the rate. In addition to the platform fee, every on-chain transaction requires a small network gas fee paid to the chain you're trading on, not to onchain.cc. Gas fees vary by chain — typically fractions of a cent on Solana and most L2s, more on Ethereum mainnet. ### Do I need a chain's native token to trade on it? Yes. Each chain charges its own gas fee, paid in that chain's native token (SOL on Solana, ETH on Ethereum, etc.) regardless of which tokens you're trading. Even if you're swapping USDC for another token, you need a small balance of the chain's native token in your wallet to pay for the transaction. **As a rule of thumb on Solana, keep at least 0.05 SOL on hand — without it, your transactions will fail. Equivalent buffers apply on other chains.** ### What is a contract address (CA)? A contract address (CA) is the unique on-chain identifier for a specific token on its native chain. Every token has one, and pasting it into the onchain.cc search bar is the fastest way to pull up that token's chart and trading panel directly — works across all supported chains. You can find a token's CA on sites like BirdEye, GeckoTerminal, Etherscan, or by asking in trading communities. Always verify the CA (and the chain) before trading to ensure you are buying the correct token. ### Why did my transaction fail? The two most common causes are insufficient native-token balance for gas fees, or slippage set too low. If your gas balance on the chain you're trading on is too low to cover the network fee, the transaction will fail before it executes. If price moved between the time you submitted and the time the transaction was processed, and the movement exceeded your slippage tolerance, the transaction is rejected to protect you from a bad fill. Try increasing your slippage tolerance slightly, or top up your native-token balance (e.g., \~0.05 SOL on Solana) and resubmit. ### What happens to my funds if I close the app? Nothing. onchain.cc is a self-custody platform — your funds live in your wallet on-chain, not on onchain.cc's servers. Closing the app, clearing your browser, or losing internet access does not affect your wallet or your positions. When you return, connect your wallet again and everything will be exactly as you left it. *** ## Colosseum ### How do I join Colosseum? You are enrolled automatically when you make your first trade on onchain.cc. There is no separate sign-up, no application, and no minimum trade size. Your points, rank, and quest progress start accumulating from your first swap. Head to the Colosseum section of the terminal to see your current rank, active quests, and session leaderboard position. ### What is the difference between a Session and a Season? A **Season** is a long-running campaign (typically several weeks to months) with a large overall prize pool. A **Session** is a shorter weekly competition — usually 4 days — that takes place inside the Season. Each Session has its own leaderboard and its own prize pool. Winning sessions advances your standing in the Season, and your rank carries forward through the whole Season. ### How do I earn more points in Colosseum? Points are earned primarily through trading volume. Your rank determines a points multiplier — higher ranks multiply the points you earn per dollar traded. To accelerate your progress, complete daily and weekly quests (which award bonus points and loot boxes), post about onchain.cc on X to earn Social Scoring points, and join a Faction for a group multiplier bonus. The more consistently you trade and complete quests, the faster your rank climbs. *** ## Support ### How do I contact support? The primary support channel is the official onchain.cc Discord server.
