How do crypto debit cards work?

A crypto debit card converts your crypto to fiat at the moment of payment, then settles with the merchant via the Visa or Mastercard network. The merchant sees a normal card payment; you see your crypto balance debited. Some cards top up from a stablecoin balance for predictable spending.

Are there fees on a crypto card?

Most crypto cards charge: a small monthly fee or none, a 1–3% conversion fee per transaction, and FX fees for purchases in non-card-currency. Some premium cards waive fees if you hold the platform's native token. Always check before using a card abroad.

Can I use a crypto card anywhere?

Crypto cards work anywhere Visa or Mastercard is accepted — globally, online, in-store, and at ATMs. Geographic restrictions apply: most cards are not available in the US (regulatory) or some emerging markets (KYC complexity). Dubai, Singapore, and the EU have the broadest crypto card access.

Is a crypto card safe?

Crypto cards are as safe as traditional debit cards from a payments perspective. The crypto risks are: centralised custody of funds backing the card, platform insolvency risk, and stablecoin de-pegging risk if you spend a stablecoin. Use cards from regulated issuers and never hold large balances.

What is a DeFi aggregator?

A DeFi aggregator is a platform that routes your crypto swaps across hundreds of decentralised exchanges (DEXes) simultaneously to find the best rate and lowest slippage. Instead of trading on a single DEX like Uniswap, an aggregator like Steyble splits your trade across multiple pools and chains to maximise your output.

What is a crypto super app?

A crypto super app is a single non-custodial platform that combines every DeFi service — token swapping, staking, perpetuals trading, prediction markets, copy trading, cross-chain bridging, and crypto cards — in one interface. Steyble is a crypto super app, meaning you never need to switch between multiple DeFi applications.

Is Steyble self-custodial?

Yes. Steyble is entirely non-custodial and self-custodial. You hold your private keys at all times. Steyble provides the interface and smart contract routing, but never holds, controls, or has access to your assets. Every transaction requires your explicit wallet signature.

How do prediction markets work in crypto?

Crypto prediction markets let you buy or sell shares in the outcome of real-world events using on-chain smart contracts. If you buy a 'Yes' share at $0.35, you receive $1 if the event occurs (a $0.65 profit) or lose $0.35 if it does not. Markets cover crypto prices, elections, sports results, and macro events. Steyble's prediction markets are non-custodial — your funds remain in your wallet until settlement.

What are perpetual futures in crypto?

Perpetual futures (perps) are leveraged crypto trading contracts with no expiry date. Unlike traditional futures that expire monthly, perps let you hold long or short positions indefinitely. A periodic funding rate keeps the perp price aligned with spot. Steyble perpetuals run on decentralised smart contracts — you trade directly from your own wallet with full transparency into liquidation parameters.

How does copy trading work on Steyble?

Copy trading on Steyble automatically mirrors the on-chain trades of verified top-performing wallet strategies. You choose the wallets you want to copy, set your position sizing and risk limits, and Steyble replicates their trades in real time. Unlike centralised copy trading, Steyble is non-custodial — you never give up control of your funds.

What is the best way to earn passive income with crypto in 2026?

The best methods for passive crypto income in 2026 are: (1) liquid staking ETH or SOL at 3.5–8% APY, (2) lending stablecoins on lending protocols at 5–9% APY, (3) non-custodial copy trading to mirror proven wallet strategies, (4) providing liquidity to stablecoin pools at 3–6% APY, and (5) on-chain prediction markets for event-driven returns. Steyble provides access to all five methods in a single platform.

What is the best DEX aggregator in 2026?

The best DEX aggregators in 2026 route across 15+ blockchains and 100+ liquidity sources with MEV protection. Steyble's swap aggregator covers 250+ liquidity sources across Ethereum, Solana, Arbitrum, Base, and more — consistently delivering better rates than going directly to any single DEX. For large swaps, using an aggregator saves 0.5–2% per transaction.

Crypto Cards: Spending Your DeFi Gains in the Real World

Crypto debit cards let you spend your crypto at any Visa merchant without manually converting to fiat. Here is how they work.

You have yield from DeFi, gains from trading, and stablecoins ready to spend — but your local coffee shop does not accept USDC. Crypto debit cards bridge the gap, converting your crypto to local currency instantly at point of sale.

What Makes Steyble Cards Different

Most crypto cards are linked to a single exchange. Steyble's card draws from your self-custodial wallet, meaning you retain custody until the moment of spending. It integrates directly with your DeFi portfolio — spend stablecoin yield without ever withdrawing to a bank.

The Tax Consideration

In most jurisdictions, spending crypto (except stablecoins in some cases) is a taxable event. Using stablecoin cards (USDC, USDT) often avoids this complexity. Check your local tax rules.
