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.

Cold Storage in 2026: Hardware Wallets and Offline Security

Cold storage keeps your crypto offline, safe from network-based attacks. Here is how to choose and use a hardware wallet correctly.

Cold storage means keeping crypto private keys completely offline — on a hardware device that never connects to the internet during normal operation. This eliminates the most common attack vector: remote exploitation via malware, phishing, or compromised apps. For serious crypto holders, cold storage is not optional.

Hardware Wallet Options in 2026

Ledger Nano X: Bluetooth + USB, most compatible device, 5,500+ supported assets, £119
Trezor Model T: open-source firmware, touchscreen, USB-C, £179 — most transparency
Coldcard Mk4: Bitcoin-only, highest security for BTC maximalists, PSBT support
Foundation Passport: open-source hardware + firmware, air-gapped option, $199 USD
BitBox02: Swiss-made, minimalist, excellent UX, Bitcoin-only or multi-edition

Hardware Wallet Security Best Practices

Buy only from the manufacturer's official website — never second-hand or from Amazon third parties
Verify the packaging is sealed and intact before first use
Set a strong device PIN — lock device after 3-5 incorrect attempts
Write seed phrase on paper at setup — never photograph or store digitally
Set a passphrase (25th word) for additional protection on Ledger/Trezor

Using Cold Storage with Steyble

Steyble supports full hardware wallet integration via WalletConnect and native Ledger/Trezor integration. You can view your cold storage holdings in Steyble's portfolio dashboard, sign transactions on the hardware device when needed (device physically must be present and PIN entered), and access DeFi protocols with hardware wallet security. Your private keys never leave the device — Steyble only requests transaction signatures, never key export.
