What are Uniswap V4 hooks?

Hooks are plugins that run custom code at key points in a pool's lifecycle — before or after a swap, or when liquidity is added or removed. They let developers build features like dynamic fees, onchain limit orders, time-weighted average market makers, and custom oracles directly into a pool, without forking Uniswap.

How is Uniswap V4 different from V3?

V4 introduces hooks for customisable pool logic, a singleton contract that holds all pools in one contract to cut deployment and multi-hop swap gas costs significantly, and flash accounting that nets balances at the end of a transaction. V3's concentrated liquidity remains, now extensible via hooks.

Does Uniswap V4 save on gas?

Yes. The singleton architecture means multi-hop swaps no longer transfer tokens between separate pool contracts, and flash accounting settles net balances once per transaction. Together these can substantially reduce gas, especially for routes that touch several pools.

Are Uniswap V4 hooks safe to use?

Hooks are powerful but only as safe as their code — a malicious or buggy hook can affect a pool. Stick to pools whose hooks are audited and widely used, and use an interface or aggregator that flags risky pools. Steyble routes swaps through vetted liquidity to avoid untrusted custom pools.

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.

Uniswap V4 in 2026: Hooks Explained + New Strategies

Uniswap V4's hooks let anyone add custom logic to liquidity pools. This 2026 guide explains hooks, the singleton design, gas savings, and the new LP strategies they unlock.

Uniswap V4 represents the largest technical redesign in Uniswap's history. Launched in early 2025, V4 introduces "hooks" — customizable smart contracts that can execute logic before/after swaps, LP deposits, and fee collection. This transforms Uniswap from a rigid protocol into a flexible infrastructure.

What Are Hooks?

Hooks are external smart contracts that attach to Uniswap V4 pools and run at defined lifecycle events. Examples: a TWAP oracle hook that executes on every swap, a dynamic fee hook that adjusts fees based on volatility, a limit order hook that executes when price reaches a target. Hooks turn V4 pools into customizable DeFi building blocks.

Key V4 Improvements

Singleton contract: all pools in one contract — 99% gas savings on pool creation
Flash accounting: pay gas for net token movements only (batch swaps much cheaper)
Native ETH support: wrap/unwrap no longer needed (saves gas on every ETH trade)
Transient storage: EIP-1153 support reduces gas cost for multi-hop routes

V4 Use Cases Enabled by Hooks

Auto-compound LP fees back into position
KYC-gated pools for institutional DeFi compliance
Subscription-based trading fees
Oracle-based dynamic liquidity ranges that shift with price
Prediction market AMMs with hook-based resolution
