How the 1inch API integration powers Zerion Wallet’s most efficient swaps

The 1inch API continues to improve Zerion users’ trading experience by offering most attractive rates in the shortest time.

The 1inch Network is always excited about successful collaborations, and the long-standing integration with Zerion Wallet has proved to be a great example. While 1inch and Zerion are familiar to most DeFi users, not everyone knows that under the hood of Zerion Wallet, the 1inch API is integrated to maximize the ease of trading. It is the Pathfinder algorithm, the backbone of the 1inch Aggregation Protocol, that allows users to get the best swap rates across Web3 in just seconds. This service addresses different challenging processes DEX traders usually struggle with — like searching for the most favorable exchange rate, the lowest slippage and the best gas fees.

How the 1inch API makes swapping easier, faster and more profitable

The 1inch API was created as an innovative discovery and routing algorithm that facilitates non-custodial asset swaps for any platform, including cryptocurrency wallets. Pathfinder offers the most favorable rate as it can split the swap between multiple protocols and even between various market depths within the same protocol, finding the best path.

The 1inch API offers access to the deepest liquidity in the market, including external liquidity via PMMs. The current number of available liquidity sources is over 250 and continues to increase. The algorithm boasts the shortest response times and protection from front-running and sandwich attacks.

What is Zerion?

Zerion is a smart and social wallet that enables users to manage their entire NFT and DeFi portfolio from a smartphone.

Unlike older wallets, Zerion makes Web3 experience more intuitive and user-friendly, even for newcomers. The built-in DeFi portfolio tracker automatically monitors all DeFi positions, rewards and debts and neatly organizes NFTs into collections, including them in the total value of the portfolio. Another helpful feature that makes token exchange smoother and faster is effortless switching between L1 and L2 networks. The wallet allows users to easily swap any token directly in the mobile app.

Under the hood, Zerion is also an ‘aggregator of DEX aggregators’. The built-in Swap feature scans prices from 0x, 1inch and all the main DEXes to suggest the best swap option that also takes slippage and gas fees into consideration.

Since launching its Swap feature in 2020, Zerion has processed over $1.4 bln in transaction volumes on Ethereum alone.

How Zerion uses 1inch API

Zerion Wallet uses 1inch API as one of the liquidity sources to find the best swap rates for its users.

When a user initiates a swap, Zerion first requests quotes from 1inch. It asks for what amount of token B 1inch wants to buy a certain amount of token A and how much the user will pay for this swap. If there is enough allowance and balance, Zerion requests transaction data for the trade.

In addition to 1inch, Zerion checks data from other sources, including Zerion’s own open-source DeFi SDK, 0x, Hashflow, Wintermute, Paraswap and DEXes. After that, Zerion offers the best rate to the user, which considers slippage, gas costs and previous approvals.

On Ethereum mainnet, 1inch is consistently one of the top liquidity sources for Zerion swaps, which is particularly valid for large trades and exotic tokens. Since the beginning of 2022, 1inch has been steadily increasing its market share among Zerion users.

Why integrate with the 1inch API

Today, given 1inch’s trading volumes, any swap aggregator would be incomplete without its API. From a practical perspective, integrating with 1inch is straightforward and advantageous for both end users and the wallet.

“The 1inch API has great documentation that makes integrations easy,” says Igor Sobolev, a smart contract engineer at Zerion. “After processing thousands of transactions we can see that the algorithm is reliable and always fast. In our experience, 1inch could be up to 2 to 3 times faster than 0x.”

“The commitment to constant development and self-improvement helps our partners and us to provide innovative services in the DeFi market,” says Sergej Kunz, 1inch Network co-founder. “And we strive to ensure that users continue to enjoy fast transactions and favorable rates.”

The integration with Zerion proves that 1inch improves swap functionality better than any single DEX. And the 1inch API benefits users with the deepest liquidity, attractive swap rates, greatest speed and security.
