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.

Ethereum Smart Contracts Explained: The Programs That Run DeFi

Smart contracts are self-executing programs on Ethereum that power all of DeFi, NFTs, and DAOs. This guide explains what they are, how they work, and their risks.

A smart contract is a program stored on a blockchain that automatically executes when predefined conditions are met. No intermediary needed: the code enforces the agreement. Every DeFi protocol — Uniswap, Aave, Compound — is a set of smart contracts running on Ethereum.

How Smart Contracts Work

When you interact with Uniswap, you send a transaction to the Uniswap smart contract. The contract checks your balance, calculates the swap rate using the AMM formula, transfers tokens, and updates state — all atomically (either everything happens or nothing happens) and transparently on-chain.

Smart Contract Risks

Code bugs: a flaw in contract logic can be exploited to drain funds (e.g. The DAO hack 2016)
Immutability: once deployed, contracts cannot be changed (unless built with upgradeability)
Oracle manipulation: contracts that rely on external price feeds can be manipulated
Composability risks: protocols built on other protocols inherit their risks

Audits and Verification

Reputable DeFi protocols have their smart contracts audited by security firms (Certik, Trail of Bits, OpenZeppelin). Audits reduce but do not eliminate risk — they are a historical snapshot, not a guarantee. The best indicator of contract safety is time: protocols with $1B+ TVL and years without hacks have demonstrated resilience.
