Multi-Bridge
Multi-Bridge is Lucid’s bridge-agnostic interoperability and bridge aggregation infrastructure for cross-chain asset and message transfers.
By integrating multiple interoperability, routing, and bridge providers into one unified execution layer, Multi-Bridge enables ecosystems to coordinate cross-chain transfers across 25+ chains without relying on isolated bridge-specific infrastructure.
Multi-Bridge combines:
- bridge aggregation
- unified transfer execution
- route optimisation
- interoperability coordination
- cross-chain liquidity routing
- consensus-enabled execution
This allows users and ecosystems to perform cross-chain transfers through one integrated environment.
Bridge Infrastructure
Multi-Bridge is built around Lucid’s unified interoperability infrastructure layer.
The infrastructure coordinates:
- transfer execution
- bridge aggregation
- routing optimisation
- liquidity movement
- interoperability messaging
- cross-chain settlement
Transfer execution is coordinated automatically through integrated interoperability providers and routing systems.
| Component | Purpose |
|---|---|
| Multi-Bridge | In-platform bridge aggregation, route optimisation, and transfer execution |
| Multi-Hop & Multi-Consensus | Deterministic routing, consensus verification, and advanced cross-chain coordination |
Integrated Bridges
Lucid integrates multiple interoperability, routing, and bridge infrastructure providers into a unified execution layer.
Supported integrations include:
- Polymer
- Wormhole
- LayerZero
- Hyperlane
- Chainlink CCIP
- Axelar
- Across
- Relay
- Everclear
- Superbridge
These integrations allow ecosystems to:
- route transfers across multiple providers
- avoid bridge lock-in
- coordinate unified liquidity movement
- access multiple interoperability systems through one infrastructure layer
Unified Transfer Interface
Multi-Bridge provides a unified interface for:
- selecting source and destination chains
- choosing supported assets
- routing transfers across integrated bridges
- executing cross-chain transfers through one interface
Transfers are executed directly within the Lucid platform through integrated bridge infrastructure.
Automatic Route Selection
Multi-Bridge automatically coordinates transfer execution depending on:
- transfer size
- bridge limits
- available routing paths
- selected execution mode
The system automatically determines whether:
- single-bridge execution
- or multi-bridge execution
is required depending on configured bridge limits.
For smaller transfers:
- execution occurs through a single interoperability provider
For transfers exceeding configured single-bridge limits:
- multi-bridge consensus execution becomes available automatically
Route Optimisation
Multi-Bridge coordinates routing through integrated interoperability and routing providers to optimise:
- transfer efficiency
- execution reliability
- routing availability
- cross-chain settlement
This allows users to access unified cross-chain routing without manually interacting with multiple bridge interfaces or liquidity systems.
Supported Transfer Types
Multi-Bridge supports:
- asset transfers
- bridge-agnostic routing
- cross-chain liquidity movement
- automatic route optimisation
- interoperability coordination
- consensus-enabled transfer execution
Transfer execution is coordinated through Lucid’s integrated interoperability infrastructure layer.
Supported Infrastructure
Multi-Bridge is built on an extended xERC20 framework supporting multiple interoperability and mint/burn standards.
This infrastructure enables:
- unified mint and burn coordination
- bridge-agnostic token infrastructure
- interoperability standard compatibility
- cross-chain liquidity coordination
| Infrastructure | Purpose |
|---|---|
| xERC20 | Cross-chain mint and burn standard |
| NTT | Wormhole interoperability support |
| CCT | Chainlink interoperability support |
| ITS | Axelar interoperability support |
| ERC-7802 | Cross-chain token compatibility |
| Custom Mint/Burn Tokens | Support for custom mint and burn permission models |
Consensus-Based Execution
When transfer amounts exceed configured single-bridge limits, Multi-Bridge can automatically enable multi-bridge consensus execution.
In this mode:
- transfers require confirmation from multiple interoperability providers
- configurable consensus thresholds are applied
- execution finalises only after required confirmations are reached
Additional consensus configuration and operational flows are covered in the Multi-Hop & Multi-Consensus section.
