Glacis
What is Glacis?
Glacis is a middleware protocol that simplifies, secures, and standardizes cross-chain messaging and token transfers. It aggregates leading General Message Passing (GMP) protocols such as Axelar, Wormhole, and LayerZero to provide a unified framework for developers building interchain applications.
What is Airlift?
Airlift is a powerful extension of Glacis that provides a universal token registry and abstraction layer for multi-chain native token transfers available exclusively via LI.FI.
Traditionally, each burn-and-mint token standard—like OFT, NTT, ITS, CCT, WarpRoutes, and xERC20—requires custom configuration, integration, and testing. Although these standards may use uniform transport protocols under the hood, the parameters for sending, receiving, and securing assets are inconsistent, which imposes a high integration burden.
Airlift solves this by:
Abstracting each bridge and token standard's special configurations into a single canonical interface
Providing an API for retrieving token configuration metadata and quoting routes
Automatically unlocking hundreds of new bridging routes for integrators like LI.FI and Jumper
For developers and integrators, this means:
No need to manually configure or test each new token or bridge
Seamless access to the latest standards and highly efficient cross-chain routes
Instant integration into dApps, wallets, or protocols with no overhead
Benefits for LI.FI Users
Through Glacis and Airlift, LI.FI users get:
Access to highly optimized cross-chain token routes without any additional setup
Support for hundreds of tokens via multiple bridge standards like OFT, xERC20, etc.
Unified messaging and token transfer logic under the hood
This integration enhances LI.FI’s position as a robust cross-chain liquidity and messaging aggregator—empowering developers to build truly chain-agnostic applications.
Integration Options
1. LI.FI Widget
2. LI.FI SDK
The desired source and destination chains
Tokens involved in the transfer
Any additional routing preferences (e.g., max slippage, integrator name)
Glacis will be automatically considered as a bridging option where relevant token routes are available if no "allowBridges" parameter is used.
3. LI.FI API
For direct API usage, Glacis routes will appear in the /quote
and /routes
endpoints. To explicitly confirm a route is powered by Glacis:
Check for
"bridge": "glacis"
or similar in the responseTokens supported via Airlift will typically be listed in the metadata
No Manual Setup Required
Glacis and Airlift are fully abstracted inside the LI.FI platform. Integrators don’t need to manage:
GMP routing configuration
Token registry integration
Gas estimations or execution
