1inch Card

What is 1inch?

1inch is a self-custodial DeFi platform focused on token swaps, cross-chain trading, wallet tools, portfolio tracking, card spending, and developer APIs. It started in 2019 as a DEX aggregator, then expanded into a broader crypto ecosystem that now reports $806B+ in swap volume, 262M+ total swaps, and 27M+ wallets connected. For readers comparing Crypto Exchanges, it sits in a different spot from a typical custodial trading app because users connect a wallet and keep control of assets.

The service is built around on-chain trading and Web3 access rather than a bank-style account. Its history is unusually specific too: the first aggregator was built in 56 sleepless hours at an ETHGlobal hackathon in New York, intent-based swaps arrived in 2022, atomic cross-chain swaps with MEV protection were added in 2024, and bridge-free swaps between Solana and EVM networks followed in 2025.

Key Features & Services

Trading is still the main draw here, but the product set is wider than that suggests. Alongside swaps, the platform now covers wallet security, portfolio monitoring, a prepaid crypto card, and B2B infrastructure for teams building Web3 products.

Swap aggregation and cross-chain trading

The core crypto exchange function is route aggregation across decentralized liquidity sources. The platform scans available paths and market depth to seek better token prices, and it supports cross-chain swaps across 13+ networks without requiring a separate bridge flow. Supported networks listed across its pages include Ethereum, BNB Chain, Polygon, Arbitrum, Avalanche, Optimism, Gnosis Chain, zkSync Era, Base, Linea, Solana, Sonic, and Unichain.

A notable part of the trading stack is MEV protection, which is meant to reduce exposure to front-running and sandwich attacks. The site also states zero gas fees on Simple swaps and describes swaps inside the wallet app as gasless.

1inch Wallet

The wallet is self-custodial, so the user keeps control of keys and assets rather than handing custody to a centralized platform. It also connects to thousands of dApps through WalletConnect and includes a built-in Web3 browser for exploring decentralized applications.

Security is a visible part of the wallet pitch. Protections described on the site include transaction scanning, domain scanning, token and address screening, and behavior monitoring aimed at scam detection. For users researching Self-Custody tools, that combination of wallet access and screening features is one of the clearer differentiators here.

Portfolio tracking and DeFi discovery

The portfolio product is aimed at monitoring digital assets across wallets and positions. It can track holdings, analyze profit and loss, and surface DeFi staking opportunities from within the same ecosystem.

That makes the platform more than a place to execute a token swap. It also works as an ongoing crypto dashboard for users who want to monitor positions after trading.

1inch Card

The card adds a spending layer to the ecosystem. It is described as a prepaid Mastercard powered by Crypto Life, developed with Baanx, and issued by Monavate.

The site says it supports online purchases, in-store payments, ATM withdrawals, Apple Pay, and Google Pay. On the regulatory side, Monavate is identified as an FCA-authorized e-money institution and a principal Mastercard member, which is relevant specifically to the card product.

Business API suite and trading terminal

On the B2B side, the company offers a business API suite with Web3 tools that include token swap APIs and RPC nodes. That places it partly in crypto infrastructure, not only consumer trading.

There is also a terminal interface with limit and market trading modes. For active DeFi users and developer teams, this broadens the service from a simple swap tool into a more operational Web3 stack.

Pricing & Fees

Public pricing is limited. The website does not publish a full schedule for swap fees, wallet costs, card charges, or API pricing, so direct fee comparison is difficult.

Service	Pricing information publicly shown
Token swaps	Full fee details not publicly listed
Cross-chain swaps	Full fee details not publicly listed
Wallet	No standalone wallet pricing published
Card	Full card fee schedule not publicly listed
Business APIs	Custom or undisclosed pricing

Two pricing-related points are stated on site pages: Simple swaps are described as having zero gas fees, and wallet swaps are described as gasless. Those statements do not replace a full fee table, so users still need to check execution details before confirming a transaction.

Pros and Cons

The offering is broad for a DeFi platform, but some practical details are still thin. The strongest points are network coverage, self-custody, and security controls, while the main drawback is incomplete public fee disclosure.

Pros

• Network coverage: Supports cross-chain swaps across 13+ networks, including Ethereum, Solana, Arbitrum, Polygon, and BNB Chain.
• Scale stats: Reports $806B+ in swap volume, 262M+ total swaps, and 27M+ connected wallets.
• Self-custody model: The wallet keeps users in control of assets instead of moving funds into custodial exchange accounts.
• Trading protection: MEV protection is designed to reduce front-running and sandwich attack risk during token trading.
• Security features: Wallet protections include transaction scanning, domain scanning, token and address screening, and behavior monitoring.
• Broader product set: Goes beyond swaps with portfolio tools, a prepaid card, a terminal, and business APIs.
• Security certifications: The security page states ISO27001 and SOC2 certification.

Cons

• Limited fee transparency: The site does not publish full pricing for swaps, card use, wallet costs, or API access.
• Wallet dependency: Some core functions require a connected wallet, which may not suit users looking for a custodial setup.
• Availability detail is thin: There is no clear country-by-country availability list for swaps or the card.
• Card scope varies: Regulatory details provided apply to the card issuer, not to every part of the crypto platform.
• Execution costs can vary: Even with route optimization, final trade outcomes in DeFi can still change with liquidity and market conditions.

Who Is 1inch Best For?

This platform suits crypto users who want a self-custodial way to swap tokens across multiple networks. It is also relevant for people active in DeFi who need wallet access, dApp connectivity, and portfolio visibility in one place rather than using separate apps for each task.

Another clear fit is multi-network traders. Cross-chain support across 13+ networks, plus market and limit trading tools, gives active users a way to manage swaps across different ecosystems without relying on a single-chain workflow.

The product also fits card users who want to spend crypto through a prepaid Mastercard setup with mobile wallet support for Apple Pay and Google Pay. Separately, developer teams and Web3 businesses may find the API suite useful when they need swap infrastructure or RPC access as part of a larger crypto product.

It is less suited to people who want a simple custodial exchange account with fully published fee schedules. This is a DeFi and crypto infrastructure service first, not a traditional retail finance app.
