Abstract Network Snapshot
Ethereum L2 with native account abstraction, built for consumer crypto. Built on the ZK Stack, Abstract is a zero-knowledge rollup built on Ethereum, offering developers an EVM-compatible environment with unique system contracts and smart-contract wallets by default.
Key features
- EVM-compatible smart contracts
- Native account abstraction (all accounts are smart contracts)
- Lower costs through bytecode hashing and reuse
- ZK-rollup security backed by Ethereum
- System contracts for advanced functionality (kernel space)
- Smart contract wallets with paymaster support

FAQ
Zerion’s Abstract API gives developers real-time wallet data across Abstract and 25+ other blockchains in a unified format. Instead of raw blockchain data, you get balances, transactions, NFTs, and DeFi positions enriched with context. This makes it much easier to build consumer-ready apps without handling the complexity of Abstract’s system contracts or bytecode deployment model.
It’s straightforward:
- Sign up and get your Zerion API key by filling out the form for the free plan above.
- Use the interactive playground to make your first Abstract API call.
- Follow our guides to fetch balances, transactions, and more across Abstract and other chains. You can be live in minutes without running your own Abstract node.
Yes. Unlike Ethereum where externally owned accounts dominate, Abstract implements native account abstraction. This means every account is a smart contract with customizable signature validation, paymaster support for gas sponsorship, and advanced wallet logic. With Zerion API, you can query these accounts just like you would any other, without extra complexity.
Abstract requires contract bytecode to be registered on L1 before deployment. Zerion API abstracts away these low-level details, so when you query contracts, balances, or transactions, you don’t need to manage bytecode hashes yourself. You just get clean, app-ready data.
Yes. Zerion API uses a unified schema across 26+ chains. The same endpoints for balances, NFTs, DeFi positions, and transactions work on Abstract without custom integration work. In fact, with a single call you can fetch from all supported chains or select the ones you need.
With Zerion API, you can query token balances, NFT holdings, transaction history, DeFi positions, and overall portfolio balance on Abstract. All results are normalized with the same structure you get across other chains.
No. Zerion API removes the need for node setup or maintenance. We handle indexing Abstract blocks, transactions, and system contract events, so you can build directly on our API endpoints.
