Score breakdown

Computed directly from the data above — see the exact formula in our methodology.

Fees2.5/5

No single fee to compare — see the fee model details in the review.

Security5.0/5

Contracts have undergone an independent security audit.

Liquidity (TVL)4.0/5

An aggregator doesn't hold its own pooled liquidity by design — it routes through other protocols' pools, so its own TVL figure doesn't reflect real market depth.

Network reach1.5/5

Available on 3 blockchain networks (scaled against 10).

About 1inch

1inch is a decentralized DEX aggregator, founded in May 2019 by Sergej Kunz and Anton Bukov at the ETHGlobal hackathon in New York. Unlike Uniswap, PancakeSwap, or Curve, it doesn't maintain its own liquidity pools as its core product — instead, it searches for the best possible price by scanning dozens of other DEXes, splitting an order across several of them when doing so lowers the cost.

How aggregation works

The 1inch Aggregation Protocol analyzes available liquidity across many DEXes simultaneously and splits larger orders to minimize price slippage. In December 2022, 1inch launched the Fusion Protocol — a model built around "intents," where the user signs an intent to transact and competing "resolvers" execute it, reducing the risk of front-running.

Supported networks

1inch started out exclusively on Ethereum, later adding BNB Chain. On April 29, 2025, it integrated Solana, and on August 19, 2025, it enabled swaps between Solana and other networks.

Fees and the 1INCH token

There's no single fixed fee of its own — the cost depends on which pools the order routes through (Uniswap, Curve) plus gas. The 1INCH token, launched in December 2020 alongside the 1inch DAO, is used to govern the protocol. In April 2021, 1inch launched the 1inch Wallet, a non-custodial mobile app that integrates the aggregator with a standard wallet.

Security

The 1inch Limit Order Protocol underwent an OpenZeppelin audit in December 2021. Because 1inch doesn't maintain its own large pools, its exposure to typical AMM risks (impermanent loss, pool math bugs) is lower — the main risk remains the security of the routing contract and of the protocols the transaction actually passes through.

Who it's for

A good fit for anyone who wants confidence in getting a competitive price without manually comparing DEXes, especially on larger transactions where splitting the order reduces slippage. Less relevant for very small, routine swaps of the same pair.

1inch Details

  • Type: Aggregator
  • Chains: Ethereum, BNB Chain, Solana
  • Typical fee: Varies by routed pools (no fixed 1inch fee) + network gas
  • Governance token: 1INCH
  • TVL: ~$2.5M (August 2026)
  • Audits: Yes
  • Official site: https://1inch.io

Pros

  • Automatically compares prices and splits orders across multiple DEXes to get a better rate than any single exchange
  • Fusion Protocol enables front-running-resistant orders (intent-based transactions, executed by competing resolvers)
  • Its own non-custodial mobile app (1inch Wallet) integrates the aggregator with a standard wallet

Cons

  • Very low own TVL (1inch doesn't hold its own liquidity) can be misleading for someone used to comparing DEXes on that metric
  • The final fee depends on which pools the transaction routes through, making cost harder to predict upfront than a DEX with one fixed rate

Technical details

A DEX is a protocol, not a company holding an account — you connect your own wallet, and funds never come under 1inch's control.

Fee model
1inch doesn't charge its own fixed swap fee — as an aggregator, it splits your order across other protocols' liquidity pools, so you pay those pools' fees (e.g. Uniswap or Curve) plus network gas. The 1inch Wallet app may charge a small service fee for select features.

User reviews

Real ratings and reviews from independent sources — we don't write them ourselves and don't edit the quoted text.

1inch Limited runs an official wallet app (1inch Wallet) on the App Store — these reviews are about that app.

„I've really liked this wallet in the past. Upgraded today and now cannot see how to trade or swap. Sending and receiving seems to be all that is possible.”

„For some reason the NFT section in my application has disappeared while still having NFT section view in settings. I have tried to set it up in settings, than reinstalled the app but nothing helps.”

MarcDolnoro, December 2023 — App Store

„Nice wallet and easy to use, built in staking and decent browser. Like the other review. Loses a star for not having British pounds.”

Djkenod, February 2022 — App Store

„Nice, clean, easy to use. Loses a star for me because there's no support for GBP Currency.”

Young Edmonds, October 2021 — App Store

Frequently asked questions

Do I need to sign up or complete KYC to use 1inch?

No — 1inch is a decentralized protocol, not a company running customer accounts. You connect your own wallet (MetaMask or Phantom, depending on the network), and funds stay under your control at all times, not 1inch's.

Is 1inch regulated?

1inch is an open-source protocol, not a licensed financial institution. Regulation of fully decentralized, non-custodial protocols without an intermediary is genuinely unsettled and varies by jurisdiction — check the rules that apply where you live rather than treating this as legal advice.

Is 1inch safe?

Yes, 1inch's contracts have undergone an independent security audit — see the review above for details.

What fees does 1inch charge?

1inch doesn't charge its own fixed swap fee — as an aggregator, it splits your order across other protocols' liquidity pools, so you pay those pools' fees (e.g. Uniswap or Curve) plus network gas. The 1inch Wallet app may charge a small service fee for select features.
