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.

Flash Loans Explained: Uncollateralized DeFi Borrowing in One Transaction

Flash loans allow borrowing millions with zero collateral — if repaid within the same transaction. This guide explains how flash loans work, legitimate use cases, and their role in DeFi attacks.

Flash loans are DeFi's most counterintuitive innovation: you can borrow $100 million with zero collateral, no credit check, and no risk to the lender — as long as you repay it all in the same transaction. The atomicity of blockchain transactions (everything happens or nothing happens) makes this possible.

How Flash Loans Work

Borrow funds from Aave or other flash loan providers
Execute any transaction logic with those funds (arbitrage, liquidation, collateral swap)
Repay the loan + fee (0.05–0.09%) in the same transaction
If the repayment cannot be made, the entire transaction reverts — lender loses nothing

Legitimate Flash Loan Use Cases

Arbitrage: buy cheap on one DEX, sell expensive on another in one transaction
Collateral swap: change your Aave collateral from ETH to WBTC without closing the position
Liquidation bots: borrow capital to trigger liquidations, earn bonus, repay loan
Self-liquidation: repay debt using collateral without separate capital

Flash Loans in DeFi Attacks

Flash loans amplify the capital available for DeFi attacks. The Beanstalk hack ($182M) used a flash loan to acquire temporary governance majority and pass a malicious proposal. Most oracle manipulation attacks use flash loans to temporarily distort prices. Flash loans are tools — their use in attacks reflects vulnerable protocol design, not flaws in flash loans themselves.
