1inch

What is 1inch?

1inch Network is a decentralized exchange (DEX) aggregator that routes trades across multiple decentralized exchanges to find better swap execution. It’s used for crypto swaps, limit orders, and related DeFi trading features across 12+ supported blockchain networks.

On BankList, it fits best under Crypto Exchanges because it helps users trade tokens via on-chain liquidity rather than running a traditional custodial exchange.

Key Features & Services

Aggregation Protocol (500+ liquidity sources)

The platform aggregates liquidity from 500+ sources (as stated on its homepage) and searches for efficient swap paths. In practice, that means a swap can be split across venues to reduce price impact, which matters most on larger trades or thinner pairs.

Fusion Mode (gasless swaps and MEV protection)

Fusion Mode is positioned as a way to execute “gasless” swaps, with gas costs covered by resolvers rather than the end user. The site also claims protection against front-running (often discussed as MEV-related risk), which is a common concern for on-chain swaps.

Limit Order Protocol

Instead of swapping at the current market price, traders can place buy or sell orders at a specific price using the Limit Order Protocol. Orders only fill when conditions are met, which can be useful for planned entries, exits, or range-style strategies.

1inch Wallet (non-custodial)

Alongside swapping, it offers a non-custodial wallet, meaning users control their private keys rather than depositing assets to a centralized platform. This aligns with BankList’s Self-Custody focus for users who prefer to keep control of funds.

Multi-chain ecosystem (12+ networks)

It supports 12+ networks, including Ethereum, BNB Chain, Polygon, Arbitrum, and Optimism. Multi-chain support can reduce fees (depending on the chain) and expands token availability compared with single-chain DEX tools.

Pricing & Fees

1inch states it does not charge additional protocol fees for swaps. Users still pay network gas fees, except in Fusion Mode where gas is covered by resolvers.

Fee item	What you pay	Notes
Protocol fee (swaps)	$0	No additional protocol fees stated
Network gas fees	Varies by chain	Typically higher on Ethereum, lower on some L2s and alternative chains
Fusion Mode gas	$0 (user-side)	Gas covered by resolvers (per site description)

Cost takeaway: your main cost driver is the underlying blockchain fee market and any price impact/slippage from the trade itself.

Pros and Cons

Pros

• Deep liquidity access via aggregation from 500+ sources
• Supports 12+ blockchain networks, giving flexibility on fees and token availability
• Fusion Mode offers a “gasless” swap path (gas paid by resolvers)
• Claims MEV/front-running protection features in Fusion Mode
• Limit orders add more control than simple spot swaps
• Non-custodial wallet option for users who want self-custody
• Large reported scale: $400B+ total volume and 13M+ users (homepage figures)

Cons

• Interface and DeFi concepts can feel complex for first-time users
• Gas fees can still be high on Ethereum when not using Fusion Mode
• US-based users may face service restrictions (per provided data)
• As with any DeFi routing, execution outcomes depend on network conditions
• Regulatory status is not disclosed on the website (per provided data)
• Multi-chain usage increases operational complexity (bridging, gas on each chain)

Who Is 1inch Best For?

• Active DeFi traders seeking better execution: If you often compare prices across DEXs, aggregation helps reduce manual checking and can improve effective pricing.
• Users who want limit orders on-chain: Traders who prefer price targets (instead of instant swaps) may find the Limit Order Protocol useful.
• Fee-sensitive swappers on supported networks: Those willing to trade on L2s or alternative chains may reduce transaction costs compared with mainnet-only workflows.
• Self-custody users: People who don’t want to deposit assets to a centralized exchange and prefer using a non-custodial wallet.
• Developers and institutional liquidity participants: The protocols are relevant for teams building on-chain trading flows or routing liquidity.

Regulatory note: the service is described as global and does not disclose a regulator on its website. In many jurisdictions, DeFi tools can fall outside classic financial licensing frameworks, but local rules vary widely.
