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.

Best Crypto Cards for UK Users in 2026

UK crypto users have several excellent card options. Here are the best crypto debit cards available to UK residents and what makes each stand out.

UK crypto card users have access to a competitive market with strong options. FCA oversight of crypto promotions (since 2023) has raised the bar for compliance, and most major crypto card providers now have UK-specific product pages and full regulatory alignment. Here are the best options.

Top UK Crypto Cards in 2026

Steyble Card (UK): FCA-registered product, USDC spending, 1.5% cashback, Apple/Google Pay, instant virtual card
Crypto.com Visa (UK): full product range available, regulated entity, competitive cashback tiers
Revolut Metal (with crypto feature): not a pure crypto card but strong crypto features + premium card perks for £12.99/month
Wirex UK: FCA-registered, multi-currency account + crypto card, good rates for GBP/EUR conversion
Coinbase Card (UK): connected to Coinbase UK, FCA-regulated, 1% BTC or 4% XLM cashback

UK-Specific Considerations

HMRC: each card transaction is a disposal — USDC cards (no CGT) simplest for tax
FCA registration: verify your card provider is on the FCA register — required for legitimate UK operation
FSCS: crypto assets are NOT FSCS protected — understand this limitation
Chargeback: card spending adds consumer protection vs direct crypto transfer — useful for merchant disputes
GBP loading: check FX fees for GBP to crypto conversion when loading your card

The UK Recommendation

For most UK users, the Steyble Card or Crypto.com Jade tier provide the best combination of cashback, regulatory compliance, and features. For tax simplicity, Steyble Card (USDC-based, no CGT) is the cleanest option. For maximum cashback with some crypto knowledge, Crypto.com Jade (3% cashback with £400 CRO stake) is excellent value for regular spenders.
