# FAQ

Quick answers to the most common questions, with links to the full pages.

## Product

**What is DeGate in one sentence?** A self-custody multichain crypto wallet: buy, sell, and earn across all leading blockchains from one unified balance, with gas and bridging handled for you. More: [What is DeGate](/about-degate/readme.md).

**Is DeGate a DEX?** No. An earlier product under the same name was an order book DEX on an Ethereum Layer 2; it was sunset in June 2025. More: [From DEX to Self-Custody Wallet](/about-degate/from-dex-to-self-custody-wallet.md).

**Which chains are supported?** 17 blockchains as of July 2026: Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, BNB Smart Chain, Avalanche, Aptos, Bitcoin, Linea, Sonic, Worldchain, xLayer, HyperEVM, Monad, and MegaETH (testnet). More: [Supported networks](/about-degate/readme.md#supported-networks).

**Is there a desktop or web version?** The mobile app is the primary product. The web app at [app.degate.com](https://app.degate.com) works in your browser: you can sign in with the same email wallet as in the app, and it supports hardware wallet connections.

**What languages does the app support?** 13 languages, including English, Deutsch, Français, Español, Italiano, 日本語, 한국어, and Chinese (simplified and traditional). The interface follows your device language settings.

## Money

**What are the fees?** Two tiers, set by the token traded against USDC: 0% for stablecoins, 0.02% for all other tokens, as of August 2026. USDC bridging and Simple Earn are free of DeGate fees. More: [Fees](/fees/fees.md).

**Can I buy crypto with a card?** Not currently. Fund your wallet by depositing crypto from any supported chain; see [Quickstart](/getting-started/quickstart.md).

**Does using DeGate require identity verification?** No. DeGate is a key-management app that does not operate user accounts, so there is no onboarding flow. Users are responsible for compliance with applicable local laws.

## Troubleshooting

**My swap is taking longer than expected.** Cross-chain swaps typically complete within 30 seconds to 2 minutes; the app shows an estimated completion time before you confirm. Check the status in the **Activity** tab; network congestion can occasionally cause delays. If a swap fails, your original tokens are returned automatically.

**My balance shows zero after a deposit.** Deposits can take a few minutes depending on the blockchain's confirmation time. Pull down to refresh. If the balance is still missing after 10 minutes, check the transaction on a block explorer (Etherscan, Solscan) to confirm it was sent to the correct address on the correct network, then contact support.

## Trust

**Who holds my keys?** You do; DeGate's servers do not hold them. More: [Security Overview](/security-and-self-custody/security-overview.md) and the [Self-Custody FAQ](/security-and-self-custody/self-custody-faq.md).

**Has DeGate been audited?** The Solana LP Handler was audited by Adevar Labs in March 2026. More: [Audits](/security-and-self-custody/audits.md).

**How do I verify I am on the real DeGate?** Check every link against [Official Links & Verified Contracts](/about-degate/official-links.md).
