## Verdict

1inch is the most-used DEX aggregator on Ethereum and EVM chains. Permissionless contracts, wallet-only swaps, no accounts at the protocol layer. The official front end geofences; community front ends bypass that. Useful as the default aggregator front-page for any EVM swap.

## Strengths

- Aggregates liquidity across many AMMs and on-chain order books on Ethereum and EVM chains.
- Open-source Pathfinder algorithm; competitive execution on most pairs.
- No-account swap UX from any EVM wallet.

## Caveats

- The official 1inch front end geofences certain jurisdictions and addresses; alternative front ends exist but require trust.
- Fiat on-ramp flows route through KYC partner providers — that is a separate product.
- On-chain history is public.
- Facts need re-verification by operator (last seeded 2026-01).

## What 1inch is

A DEX aggregator that routes swaps across many on-chain venues (Uniswap, Curve, PancakeSwap, others) to find the best execution path. Permissionless at the protocol layer.

## Threat-model fit

Swap venue for EVM-native users. Wallet hygiene determines correlation.
