What Is 1inch? An Honest Review
Published ยท Updated
1inch is a DEX aggregator that grew up on Ethereum: it splits and routes swaps across many AMMs to chase a better fill than any single pool. If Jupiter is that job on Solana, 1inch is the name most EVM users still hear first. I have no sponsorship or affiliate relationship with 1inch.
What It Is
A routing engine plus a website and app. You connect a wallet, pick two tokens, and it proposes a path. Classic mode is an on-chain swap through their router. Fusion mode is a Dutch-auction style intent: resolvers compete to fill you, which can reduce sandwich risk if it works as advertised. There is also a governance token, 1INCH, which you do not need in order to swap.
Strengths
- Pathfinding on EVM is the core competency. For mid-size trades across fragmented pools, aggregation is a real, boring improvement.
- Wide chain coverage on the EVM side, so you are not learning a new router per L2.
- Fusion, when it fills, is a serious attempt at the MEV problem rather than a blog post about it. Still not magic. Keep slippage sane.
Weaknesses and Honest Warnings
- The token is a side quest. Staking 1INCH for "governance" or fee discounts is optional complexity. The swap does not require it. Do not buy the token to "use the product."
- Router approvals. Unlimited allowances to any aggregator are how old signatures become future drains. Use Permit2 flows when the wallet shows them clearly, and clean up with Revoke.cash.
- Fake 1inch sites are a permanent phishing set. Type 1inch.com or use a bookmark. Ads are not a navigation tool.
- Thin-junk routes still fill thin junk. An aggregator cannot make a honeypot honest.
Who It Is Good For
EVM users swapping size that would hurt in a single shallow pool. Who can skip it: people whose entire on-chain life is one deep Uniswap pair, and anyone who was about to buy 1INCH because the app existed. Compare with Uniswap itself and, on Solana, Jupiter.
