What is DeFi (Decentralised Finance)?

DeFi is a category of financial services built on public blockchains and smart contracts, removing the need for banks or brokers. Users keep custody of their assets and interact directly with protocols for lending, swapping, staking and trading.

Is DeFi safe to use in 2026?

DeFi has matured significantly since 2020. The largest protocols are audited multiple times and have billions of dollars in total value locked. Risks remain — smart contract bugs, governance attacks, and oracle manipulation — so users should stick to established protocols and never risk more than they can afford to lose.

How is DeFi different from a centralised exchange?

A centralised exchange (CEX) holds your crypto on your behalf and matches buyers and sellers internally. DeFi protocols never hold your funds — you connect a self-custodial wallet and interact with smart contracts directly. The trade-off is more responsibility for security in exchange for full control.

Do I need to pay tax on DeFi earnings?

In most jurisdictions, yes. Yield from staking, lending, and liquidity provision is generally treated as taxable income. Capital gains apply on swaps and disposals. Tax rules vary widely — Dubai (no personal income tax), Singapore (no tax on individual crypto gains), the UK (CGT) and the US (income + CGT) all differ. Consult a qualified accountant.

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.

How DeFi Aggregators Work: The Technology Behind Better Swap Rates

DeFi aggregators scan hundreds of liquidity sources to find the best route for your swap. This guide explains the technology behind DEX aggregators, how routing algorithms work, and why aggregators beat single DEXes.

A DeFi aggregator is a smart routing layer that sits on top of DEXes. Instead of sending your entire swap through one pool, the aggregator splits it across multiple pools and chains to find the mathematically optimal path.

The Routing Algorithm

Aggregators run pathfinding algorithms modelling hundreds of possible routes simultaneously. For a USDC-to-ETH swap, splitting across Uniswap V3, Curve, and a smaller DEX can produce 0.4% more ETH than using any single source.

MEV Protection: Defending Against Front-Running

MEV bots monitor the mempool for large swaps and front-run them. Advanced aggregators route through private mempool services that make your transaction invisible to MEV bots, saving users $500M+ annually.

Cross-Chain Aggregation

The latest aggregators like Steyble also evaluate cross-chain routes. If bridging to Arbitrum and swapping there produces better output, the aggregator handles that automatically in one step.
