Use 1inch APIs across 4 new networks

1inch Business has expanded to Monad, Cronos, HyperEVM and Arc, giving developers access to 1inch infrastructure across four more fast-growing blockchain ecosystems.

Building a multichain product should not mean rebuilding your infrastructure every time you add a network.

That is why 1inch Business continues to expand its blockchain coverage. Developers can now use 1inch APIs across four more networks: Monad, Cronos, HyperEVM and Arc.

From high-throughput EVM execution to stablecoin-focused infrastructure, each network targets a different part of the on-chain economy. For developers, the expansion means more chains can be integrated through the same 1inch infrastructure.

One integration, four more ecosystems

1inch Business brings DeFi infrastructure together under one platform, covering swaps, liquidity aggregation, blockchain data and other building blocks for wallets, dApps, fintech products and agentic applications.

The four new networks extend that reach into some very different ecosystems.

Monad is a high-performance, Ethereum-compatible Layer 1 designed to increase throughput without forcing developers to abandon familiar EVM tooling. Its architecture uses parallel execution and targets 10,000 transactions per second, with fast blocks and finality. For teams already building with Ethereum tools, that makes Monad a natural environment for high-frequency on-chain applications.

Cronos is an EVM-compatible Layer 1 built on the Cosmos SDK and supported by Crypto.com. Its ecosystem spans DeFi, payments and consumer crypto applications. EVM compatibility means developers can reuse familiar smart contracts, wallets and backend patterns while reaching the Cronos ecosystem.

HyperEVM brings smart contract programmability to the Hyperliquid ecosystem. It shares HyperBFT consensus with HyperCore and is designed to allow EVM applications to interact with Hyperliquid's broader on-chain financial infrastructure. That creates opportunities for developers building DeFi applications around an ecosystem already focused heavily on trading and liquidity.

Arc, built by Circle, takes a different approach. The EVM-compatible Layer 1 is purpose-built for stablecoin finance. It uses USDC for gas, offers deterministic sub-second finality and includes infrastructure designed for payments, FX and tokenized assets. For developers building financial applications, predictable dollar-denominated transaction costs can simplify both product design and user experience.

Bring 1inch infrastructure into your app

Supporting another blockchain involves much more than adding a network selector. Applications need reliable access to liquidity, blockchain state, token data, prices and transaction infrastructure.

1inch Business brings those building blocks into one platform. Its API suite includes Swap API, Balance API, Spot Price API, Token API, Portfolio API, Web3 RPC API and other infrastructure for building on-chain products. API availability varies by network.

That means a wallet expanding to a new chain does not necessarily need to build every component from scratch. A DeFi app can connect to 1inch infrastructure as it adds networks. An AI agent can use the same API environment as it starts interacting with new ecosystems.

Developers also get a single 1inch Business account and API key, alongside SDKs, an interactive API Playground and AI development tools, including the 1inch MCP server.

Multichain development without multichain fragmentation

Monad, Cronos, HyperEVM and Arc were built with different priorities. But developers expanding across them face a common problem: every additional network can add another layer of infrastructure to maintain.

1inch Business aims to reduce that fragmentation. Instead of treating every new chain as a separate stack, developers can use the same 1inch infrastructure as their products move across more of the on-chain economy. Four more networks are now within reach.
