LayerZero:
Cross-Chain DvP Settlement
A custom decentralised application enabling atomic, real-time settlement between security tokens and payment tokens across multiple chains using LayerZero’s messaging protocol.

The Mission
“To provide the foundational messaging layer that enables secure, trust-minimised communication across 70+ blockchain networks.”
Core Objectives
- Atomic settlement across multiple chains
- Trust-minimised DvP for regulated security tokens
- Abstracted UX hiding cross-chain complexity
- Financial-grade reliability and speed
The Challenge
Atomic settlement across chains is complex due to asynchronous execution. Security tokens (ERC-3643 RWAs) often exist on regulated chains while payments exist on general-purpose chains, and manual bridging introduces risk, friction, and operational failures.
Settlement must occur atomically — either both sides complete or neither does. The system needed to guarantee accurate message delivery between Polygon and Base while maintaining compliance alignment for ERC-3643 tokens. There was no room for user error.
What We Built
Cross-Chain Settlement Engine
Locking security tokens on Chain A and releasing payment tokens on Chain B with full atomicity via LayerZero messaging.
Event Indexer & Monitor
Real-time cross-chain event tracking, generating a complete history and record of all settlement events and outcomes.
Smart Contract Architecture
Extension and adjustment of PoC smart contract logic for production-grade cross-chain DvP settlement with ERC-3643 compliance.
Unified dApp Interface
Clean, single-step UX that abstracts all cross-chain complexity into an intuitive settlement experience for institutional users.
Technical Architecture
A flow where the LayerZero messaging layer communicates state changes between chains in real-time, enabling fully automated cross-chain settlement without requiring users to bridge assets or understand chain-specific complexities.
Real Impact.
LayerZero DvP demonstrated institutional-grade cross-chain settlement, proving that regulated security tokens can be settled atomically across chains without manual bridging.
