You want a simple centralized exchange experience or are new to managing your own crypto wallet.

What is 1inch?

1inch is a decentralized finance platform built around a DEX aggregator that scans liquidity across more than 100 exchanges and 13+ blockchain networks to find users the best token swap rates while minimizing slippage. It has grown beyond simple swaps into a broader ecosystem covering limit orders, cross-chain transfers via atomic execution, and MEV protection against front-running and sandwich attacks. The ecosystem includes a web-based Swap and Trade interface, the 1inch Wallet mobile app for self-custody token management, 1inch Portfolio for tracking DeFi positions across chains, a 1inch Card for spending crypto via Apple Pay/Google Pay, and a Business API suite for developers who want to embed swap functionality into their own products. Wallet screening powered by ZeroShadow and TRM Labs adds scam and fraud protection on top of the core aggregation engine.

Pros & Cons of 1inch

Pros

Aggregates a very large number of liquidity sources, often improving swap prices versus using a single DEX
Non-custodial by design, so users retain control of their private keys and funds
Cross-chain swaps avoid the extra steps and risk of manual bridging
Built-in MEV and scam protections that most single-DEX interfaces lack

Cons

Network gas fees still apply and can be significant during congestion regardless of 1inch's own fee structure
The breadth of products (Wallet, Card, Portfolio, Business API) can be confusing for users who just want a simple swap
As with any DeFi protocol, smart contract and market risk remain, and losses from user error are not reversible

Curve Finance

AI-suggested

Curve Finance is a decentralized exchange (DEX) built around an automated market maker (StableSwap, now StableSwap-NG) designed specifically for efficient, low-slippage trading between stablecoins and other closely pegged assets like staked ETH derivatives. It runs across roughly seven chains, including Ethereum, Arbitrum, Optimism, Polygon, Base, and Avalanche, with liquidity providers earning trading fees for supplying assets to its pools. The protocol also issues its own overcollateralized stablecoin, crvUSD, mintable on Ethereum mainnet, and is governed by holders who lock CRV tokens into veCRV to vote on pool gauges and fee distribution. As a fully decentralized, non-custodial protocol, Curve has no account signup or subscription; users connect a self-custody wallet and pay only network gas fees plus small per-swap trading fees.
