1inch

1inch receives a B- risk grade (33/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — battle-tested aggregator with 15+ audits, but third-party routing and recent infrastructure incidents keep it from a higher grade A swap aggregator that finds the best prices across dozens of decentralized exchanges, saving users money on every trade. It has raised $190M in funding with a $280M fully diluted valuation. Its B- grade reflects solid auditing and a strong track record, offset by a $5M exploit on deprecated code in March 2025 and a frontend supply chain attack in October 2024.

The key risks identified for 1inch are: (1) A $5M hack in March 2025 drained funds through an old, outdated version of the swap contract. The current contracts were unaffected but the deprecated code should have been decommissioned sooner. (2) Your trades get routed through other exchanges that 1inch doesn't control. If one of those exchanges gets hacked, your swap could be affected. (3) The Fusion+ cross-chain system relies on professional middlemen called resolvers who can abandon your trade mid-execution during a market crash, leaving you with failed transactions.
