Key Features

As a sovereign Rollup L1 framework built on Celestia, ABC delivers exceptional performance, flexibility, and sovereignty.

Performance & Scalability

Gigagas Throughput

• 1 Gigagas Per Second Processing: ABC Stack achieves throughput of 1 Gigagas per second — vastly more processing capacity than conventional L2s — by removing the computational overhead of settlement layer bridges and optimizing the execution layer specifically for Celestia's DA.

• Low Block Times: Enjoy rapid transaction confirmations (up to 100ms) with minimal latency through optimized block production pipelines and by eliminating the dependency on Ethereum's block time constraints

• Real-Time State (WIP): Experience near-instantaneous (10ms) state updates by implementing partial block architecture where state updates can be broadcasted before complete blocks are finalized.

Advanced Block Building

• Custom Block Building: Developers can define custom rules for transaction inclusion and ordering through modifiable block building logic.

• Rollup Boost Integration: Connect to external specialized block builders who can optimize block construction for specific needs like MEV protection.

• Lazy Block Building: Conserve resources by generating blocks only when needed rather than at fixed intervals.

• Dynamic Block Gas Limits: Automatically adjust block capacity based on network demand through configurable parameters that can change during runtime.

• Custom/Dynamic EIP-1559 Configurations: Customize base fee algorithms and fee market mechanics to optimize for your specific economy.

Sovereignty & Architecture

True Blockchain Sovereignty

• No Settlement Costs: Eliminate unnecessary fees and complexity by removing the enshrined Ethereum bridge

• Sovereign Design: Operates as its own settlement layer with complete authority over chain rules, upgrades, and parameters.

• Independent State Validation: Verifies transactions through its own network of nodes that run full state validation without relying on external chains.

• Protocol Sovereignty: Enables governance decisions to be made by the chain's own community without requiring approval from any parent chain.

Modular Architecture

• Celestia Integration: Leverage Celestia for data availability and consensus

• Modular Bridging: Implements bridges as separate modules that can be added, removed, or upgraded independently from the core protocol.

• No Reorgs: Benefit from Celestia's single-slot-finality for transaction certainty

• ZK Ready: Designed with future compatibility for zero-knowledge proof integration through a modular architecture that can incorporate ZK verification.

• Sequencer HA Setup (WIP): High availability sequencer configuration for maximum uptime

User Experience

Account Abstraction & Onboarding

• Sequencer Sponsored Transactions: Implement EIP-7702 to allow users to delegate their EOAs to smart contracts with sequencer-sponsored costs

• Passwordless Onboarding: Integrates with WebAuthn standard to let users authenticate using biometrics or hardware keys rather than managing private keys.

• Gasless Transactions: Optionally enable zero gas price operations that can be dynamically configured

• Private Mempool: Enable a protected transaction pool visible only to block producers, preventing frontrunning by keeping pending transactions confidential.

Advanced Account Features

• Call Batching: Send multiple calls in a single transaction to reduce gas costs and improving UX

• Gas Sponsorship: Allow any entity to pay for fees in any ERC20 or ETH through relayer infrastructure that detects user-signed messages and submits them as transactions with gas paid by designated sponsors.

• Access Control: Whitelist receivers, function selectors, and arguments

• Session Keys: Creates temporary limited-privilege keys through smart contracts that can authorize specific actions without full account access.

• Multi-factor Authentication: Combines multiple signature verification requirements in smart contracts to ensure multiple authentication factors are validated.

• No Vendor Lock-in: Built on top of standards that have powered Ethereum for years to ensure portability across different implementations.

Technical Capabilities

Cryptographic Precompiles

• EIP-7212: Provides native support for secp256r1 curve through an efficient low-level implementation at the EVM level.

• EIP-2537: Implements BLS12-381 curve operations as EVM precompiles for efficient zero-knowledge proof verification and threshold signatures.

• Prague Hardfork: Activates the latest Ethereum technical improvements ahead of mainnet by implementing the Prague EIPs directly in the execution client.

Smart Contract Infrastructure

• Preinstalled Contracts: Deploy with essential contracts available from genesis, including:

  • Safe Ecosystem: Safe, SafeL2, MultiSend and MultiSendCallOnly at standardized addresses

  • Deployment Utilities: Safe Singleton Factory, create2Deployer, CreateX, and Arachnid's Deterministic Deployment Proxy

  • ERC-4337 Support: EntryPoint v0.6.0 and v0.7.0 with required SenderCreator dependencies

  • Developer Tooling: Multicall3 for batched calls

  • DeFi Infrastructure: Permit2 for token approvals

• Utility Contracts: Includes multicaller, create3, and other foundational infrastructure

Interoperability

• Gelato Hyperlane Cluster: Integrates dedicated messaging infrastructure that connects your chain to 100+ blockchains through secured messaging pathways.

• Native or Bridged Token Options: Provides flexibility to either mint tokens directly on your chain or use token bridge infrastructure to import existing assets.

• Chain Abstraction (WIP): Invisible cross-chain transactions powered by ERC-7683 intent standard to eliminate cross-chain complexity from users by having intermediaries handle the execution details.

Privacy & Security

• Private Transactions: Support for confidential transactions and transaction privacy to encrypt transaction amounts while still allowing verification of balance correctness through ZK.
• Recovery Options: Multi-path account recovery via social, email, OAuth, or other identity providers

• Privacy-Preserving Identity: Options for ZK Passport or similar verification where users can prove attributes without revealing sensitive data
