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: Borrowing Millions with Zero Collateral

Flash loans let you borrow unlimited crypto with zero collateral — if you return it in the same transaction. Here is how they work and what they are used for.

Flash loans are one of the most extraordinary innovations in DeFi: a loan of any size, requiring zero collateral, that must be borrowed and repaid within a single blockchain transaction. If the loan is not repaid by the end of the transaction, the entire transaction is reversed as if it never happened. This creates a powerful tool for arbitrage, liquidations, and collateral swaps.

How Flash Loans Work

Request a flash loan from Aave or other protocols — borrow up to available pool size
In the same transaction: use the funds for your strategy (arbitrage, liquidation, etc.)
Return the borrowed amount + fee (typically 0.05-0.09%) in the same transaction
If repayment fails, entire transaction reverts — no loss for the protocol, no gain for borrower
Gas cost is the only upfront cost — the loan itself requires nothing except repayment

Legitimate Uses of Flash Loans

Arbitrage: borrow $1M in USDC, buy ETH cheaply on Exchange A, sell at higher price on Exchange B, repay loan, keep profit
Collateral swap: replace your USDC collateral with ETH in a single transaction — no manual multi-step process
Liquidation: borrow to fund a liquidation, earn liquidation bonus, repay loan, keep bonus
Self-liquidation: avoid penalties by using a flash loan to repay your own undercollateralised loan elegantly

Flash Loan Attacks

Flash loans have also been used to exploit vulnerable DeFi protocols. By borrowing large amounts and manipulating oracle prices within a single transaction, attackers have stolen hundreds of millions. Notable exploits: bZx (2020, $1M), Pancake Bunny (2021, $45M), Mango Markets (2022, $116M). Steyble only integrates protocols with oracle manipulation resistance — time-weighted average prices (TWAP) rather than spot price oracles.
