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.

Public and Private Keys Explained: The Cryptography Behind Your Wallet

Every crypto wallet is built on public-private key cryptography. Understanding how keys work explains why self-custody is secure, why losing keys means losing crypto, and how transactions are signed.

A cryptocurrency wallet does not store coins — it stores cryptographic key pairs that prove ownership on the blockchain. Understanding these key pairs is fundamental to understanding why crypto works, why self-custody is secure, and why seed phrase loss is catastrophic.

How Key Pairs Work

Private key: a random 256-bit number — only you should have this
Public key: derived mathematically from the private key (one-way function)
Address: derived from public key by hashing — this is what you share to receive crypto
Signature: proving you own the private key without revealing it, via digital signature algorithm (ECDSA)

The Seed Phrase: Root of All Keys

A seed phrase (12 or 24 words from BIP-39 wordlist) encodes the root private key. From this root, a deterministic derivation path (BIP-44) generates separate key pairs for Bitcoin, Ethereum, Solana — all from one phrase. This is why a seed phrase can restore your entire multi-chain wallet.

Why Public Key Cryptography Is Secure

The one-way function used (elliptic curve multiplication) is computationally infeasible to reverse. To derive a private key from a public key requires solving the discrete logarithm problem on the secp256k1 curve — which with current technology would take longer than the age of the universe. Quantum computing is a long-term consideration but no imminent threat.
