Tesseract

Cross-Rollup Atomic Transaction Execution System

Tesseract enables coordinated transaction processing across multiple Layer 2 rollups with atomic execution guarantees. Built with Vyper smart contracts for maximum security.

What is Tesseract?

Tesseract is a production-ready protocol for executing atomic transactions across multiple blockchain rollups. It solves the fundamental challenge of cross-chain coordination by providing:

  • Atomic Execution: All-or-nothing transaction semantics across rollups
  • Dependency Resolution: Intelligent handling of transaction dependencies
  • Time-Bounded Coordination: Guaranteed execution within defined windows
  • Security-First Design: Built with Vyper for memory safety and overflow protection

Use Cases

Cross-Chain DeFi

Execute atomic trades, rebalance liquidity pools, and coordinate lending operations across Ethereum, Polygon, Arbitrum, and Optimism.

Enterprise Workflows

Enable complex business logic across blockchain networks for supply chain, identity management, and payment rails.

Protocol Infrastructure

Build bridges, oracle networks, and interoperability layers with strong atomicity guarantees.

Key Features

  • :material-shield-check:{ .lg .middle } Security First

    Vyper smart contracts with built-in overflow protection, role-based access control, and emergency circuit breakers.

  • :material-link-variant:{ .lg .middle } Cross-Rollup Coordination

    Atomic execution across Ethereum, Polygon, Arbitrum, and Optimism with dependency resolution.

  • :material-clock-fast:{ .lg .middle } Time-Bounded Execution

    Configurable coordination windows (5-300 seconds) ensure predictable transaction timing.

  • :material-gas-station:{ .lg .middle } Gas Optimized

    Efficient on-chain operations with ~80k gas per buffer and ~40k per resolution.

Architecture Overview

Tesseract uses a buffer-resolve-execute pattern:

  1. Buffer: Transactions are submitted with dependency information
  2. Resolve: Dependencies are validated and timing constraints checked
  3. Execute: Ready transactions are atomically executed across rollups
