ABC Stack is a next-generation Rollup L1 framework built on top of Celestia’s Sovereign Rollup paradigm. Designed for high-throughput, developer flexibility, and complete sovereignty, ABC Stack delivers an execution-first blockchain architecture without the constraints of traditional Layer 2 solutions.

​
Why ABC Stack?

​
Sovereign by Design

Unlike L2 rollups that rely on enshrined bridges and external settlement layers (like Ethereum), ABC Stack operates as a sovereign rollup. This means:
  • No dependency on external smart contracts for settlement.
  • Full control over execution, consensus, and governance.
  • No settlement layer fees or architectural complexity.

​
Modular Architecture

ABC Stack cleanly separates the core blockchain functions:
  • Execution: Handled entirely within the sovereign rollup.
  • Data Availability & Consensus: Powered by Celestia.
  • Bridging: Modular and customizable — choose when and how to integrate.

​
Performance & Scalability

​
Gigagas Throughput

ABC Stack delivers 1 Gigagas per second throughput — significantly outperforming L2s — by optimizing execution and removing settlement overhead.

​
Low Latency & Fast Finality

  • Sub-100ms block times through optimized production pipelines.
  • Partial block architecture enables near-instant (10ms) state updates.
  • No reorgs, thanks to Celestia’s single-slot finality.

​
Advanced Block Building

  • Custom Block Logic: Define custom transaction rules and orderings.
  • Rollup Boost Integration: Leverage external block builders for MEV protection or custom needs.
  • Lazy Block Building: Blocks are generated on-demand to conserve resources.
  • Dynamic Gas Limits: Automatically scale block gas capacity with demand.
  • Custom EIP-1559: Modify fee mechanics to match your app’s economy.

​
Developer Infrastructure

ABC Stack comes with critical smart contract infrastructure preinstalled:
  • Account Abstraction: Supports EIP-4337 (EntryPoint v0.6.0 & v0.7.0).
  • Safe Contracts: Includes Safe, SafeL2, MultiSend, and more.
  • Deployment Tools: Safe Singleton Factory, create2Deployer, Arachnid’s CreateX.
  • DeFi Ready: Permit2, Multicall3, and other utility contracts.

​
Cryptographic Precompiles

  • EIP-7212: Native support for secp256r1 for WebAuthn keys.
  • EIP-2537: Efficient BLS12-381 curve ops for ZK and threshold signatures.
  • Prague Hardfork EIPs: Future-proofed with latest Ethereum tech.

​
Privacy, UX, and Account Features

  • Gasless & Sponsored Transactions via EIP-7702.
  • WebAuthn Integration: Biometric and passwordless onboarding.
  • Call Batching & Session Keys: Streamlined and secure user flows.
  • Multi-Factor Authentication: Smart contract-level 2FA.
  • Private Mempools: Prevent frontrunning with confidential transaction pools.

​
Modular Bridging & Interop

  • Gelato Hyperlane Cluster: Connect to 100+ chains with modular messaging.
  • Native or Bridged Tokens: Choose your token model.
  • Chain Abstraction (WIP): Use ERC-7683 intents for invisible cross-chain UX.

​
Security & Identity

  • ZK Privacy: Confidential transactions and attribute proofs.
  • Flexible Recovery: Social, OAuth, and multi-path account recovery.
  • ZK Passport Support: Anonymous verification with integrity.

​
Conclusion: The Future of Sovereign Blockchain Design

ABC Stack realizes the full potential of the modular blockchain thesis. By eliminating the architectural constraints of L2s, embracing Celestia’s modular DA layer, and empowering developers with robust tooling and sovereign control, ABC Stack is the ideal foundation for building scalable, secure, and user-friendly applications — from fully on-chain games to high-throughput DeFi protocols.
“Where we’re going, you won’t need settlement layers.”
ABC Stack is the future — and it’s sovereign.
