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.

MEV Explained: How Sandwich Attacks Steal From Traders

Maximal Extractable Value (MEV) costs DeFi traders hundreds of millions per year. This guide explains sandwich attacks, frontrunning, and how to protect your trades.

MEV (Maximal Extractable Value) is profit extracted by block producers (miners/validators) or bots by reordering, inserting, or censoring transactions. In 2025, over $2B in MEV was extracted from Ethereum users. Most retail traders are unaware they are losing to it on every swap.

What Is a Sandwich Attack?

When you submit a swap with >0.5% slippage tolerance, bots scan the mempool, spot your transaction, and insert: (1) a buy order before yours to push the price up, (2) your transaction at the worse price, (3) a sell order after yours to pocket the spread. You receive fewer tokens; the bot profits the difference.

Other Common MEV Strategies

Frontrunning: copying your transaction with higher gas to execute first
Backrunning: trading after a large price-moving transaction
Liquidation sniping: racing to liquidate undercollateralized positions
JIT liquidity: just-in-time LP position placed and removed in same block to capture fees

How to Protect Yourself

Use MEV-protected RPC endpoints like Flashbots Protect or MEV Blocker
Set tight slippage: 0.1–0.3% for liquid pairs (Steyble does this automatically)
Use DEX aggregators that route through private mempools
Trade on L2s: MEV is significantly reduced on Arbitrum and Base
