About Etherspot

Etherspot provides developers with account and chain abstraction infrastructure to simplify and scale dApps. Whether you're building wallets, DeFi, NFTs, or other blockchain apps, our tools streamline development and improve the user experience.

account abstraction SDK Web3 cross-chain

Etherspot is a full-stack infrastructure platform designed to transform the way developers and users interact with the Web3 ecosystem. Built on Account Abstraction and Chain Abstraction technologies such as ERC-4337 and ERC-7579, Etherspot simplifies the creation of seamless, gas-efficient, and user-friendly dApps. The platform offers modular, open-source tooling that removes traditional blockchain UX complexities—empowering developers to onboard Web2 users with minimal friction.

At its core, Etherspot provides a comprehensive development suite including SDKs, bundlers, and Paymaster services. These tools enable smart account creation, cross-chain operations, and gasless transactions without requiring users to hold native tokens. With live support for major EVM chains and integrations into leading platforms like Trust Wallet and KlimaDAO, Etherspot is helping developers launch scalable and intuitive blockchain applications for a multi-chain world.

Etherspot is a groundbreaking platform for building dApps powered by Account Abstraction and Chain Abstraction. By abstracting away the underlying blockchain complexity, it allows developers to deliver Web2-level user experiences in the Web3 world. The project gained early traction by receiving a grant from the Ethereum Foundation for pioneering Shared Mempool innovations using the ERC-4337 standard. Today, it supports top EVM networks including Ethereum, Polygon, Arbitrum, Optimism, Fuse, Mantle, and Base.

The platform offers multiple developer-focused products: the Modular SDK for customizable ERC-7579 smart accounts; Prime SDK for frictionless account abstraction integration; TransactionKit for simplified frontend development using React; Skandha Bundler for bundling multiple user operations into single transactions with MEV protection; and Arka Paymaster for gasless and sponsored transactions. These services are open-source, audited, and built for rapid deployment.

What sets Etherspot apart is its focus on empowering projects across various Web3 verticals: wallets (Trust Wallet, Pillar), DeFi (GMX, Honeyswap), NFTs (Ninfa), gaming (Ancient8), and real-world use cases (Mystic Valley Festival). This adaptability has made it a preferred account abstraction layer among developers seeking to support cross-chain user experiences without deploying contracts on every network.

The main alternatives or comparable platforms include Biconomy, ZeroDev, and Alchemy’s Account Abstraction toolkit. However, Etherspot stands out for its modular SDK support, open-source ethos, and seamless integration options that reduce engineering lift and time-to-market.

Etherspot offers powerful features and benefits for developers building the next generation of Web3 applications:

Account Abstraction SDKs: Leverage Prime SDK and Modular SDK to build customizable and secure smart accounts compliant with ERC-4337 and ERC-7579.
TransactionKit: A React-based library enabling dApps to batch and process transactions in one click. No advanced blockchain knowledge is required to use it.
Cross-Chain UX: Build once and interact with over 22 supported EVM chains without deploying on each individually.
Gasless Transactions: Integrate Arka Paymaster to allow users to pay gas in ERC-20 tokens or have their fees sponsored entirely.
Skandha Bundler: Reduce gas costs through bundled transactions with MEV protection, supporting EntryPoint v0.6 to v0.8 and EIP-7702.
Audited & Open Source: Audited by ConsenSys Diligence and Nethermind, Etherspot’s tools are fully open source and accessible via GitHub.

Getting started with Etherspot is simple, whether you're a frontend developer or a Web3 engineer:

Install SDK: To integrate Etherspot’s Modular SDK, run npm i @etherspot/modular-sdk in your project.
Use Prime SDK: Clone the starter repo via GitHub, install dependencies with npm i, and run npm start.
Implement TransactionKit: For React apps, install the TransactionKit library and import its components. With only a few lines of code, you can batch transactions and enable smart account interactions.
Deploy Gasless Transactions: Use the Arka Paymaster for sponsored transactions and stablecoin gas payments.
Run a Bundler: Use Skandha to deploy your own ERC-4337 compliant bundler with one command or via Docker.
Explore Docs: The full documentation is available at etherspot.io/docs for each SDK and tool.

Etherspot FAQ

Etherspot isn’t just another SDK — it's a full-stack Account & Chain Abstraction platform that embeds modular smart accounts at the heart of dApp design. Unlike traditional blockchain SDKs that require manual network-specific deployments, Etherspot lets developers build once and deploy across 22+ EVM chains without the overhead. With support for ERC-4337 and ERC-7579, it offers unmatched customization, usability, and decentralization.
Etherspot dramatically simplifies multi-chain dApp development by offering a plug-and-play architecture through its TransactionKit and Modular SDK. Developers no longer need to deploy separate smart contracts for each EVM chain. With a few lines of code, they can enable cross-chain transactions, batched operations, and account abstraction — all without managing gas payments or custom logic for each chain.
The Arka Paymaster enables gasless transactions by sponsoring transaction fees for users or letting them pay with ERC-20 tokens like stablecoins. This means dApp users don’t need native tokens like ETH to interact with Web3. It’s particularly useful for onboarding new users unfamiliar with crypto wallets. Projects can integrate Arka easily through Etherspot’s infrastructure and fund their paymaster wallet via an intuitive dApp (coming soon).
Yes, with TransactionKit, Etherspot’s React library, you can batch multiple transactions into a single user operation. This allows for smoother UX — for example, token approval + transfer in one click. Batching is handled behind the scenes, so developers don’t need deep blockchain knowledge to implement this. It improves both speed and security by reducing unnecessary signature prompts and network congestion.
Etherspot supports 22+ EVM-compatible chains, including Ethereum, Polygon, Arbitrum, Optimism, Gnosis, Fuse, BNB Chain, Avalanche, Linea, Mantle, and more. This support ensures that developers can build and deploy cross-chain dApps without duplicating infrastructure across networks. To view the latest supported chains, visit etherspot.io.
