Allium’s bridges vertical covers three categories of cross-chain protocols, each with dedicated inbound and outbound tables unified across all supported chains.

​
Protocol Categories

​
Bridges

Application bridges that use their own liquidity or locking mechanisms to move assets between chains. Each transfer involves a token deposit on the source chain and a corresponding release or mint on the destination chain. Protocols covered: Across (v2, v3), DeBridge (DLN + Gate), Gas Zip, Mayan (MCTP, Swift), Rhino, Stargate (v2), USDT0

​
Messaging Protocols

General-purpose cross-chain communication layers that enable both token transfers and arbitrary message passing. Transfers are modeled as messages with optional token payloads. Protocols covered: Axelar, Chainlink CCIP, Circle CCTP (v1, v2), Hyperlane, LayerZero (v2), Socket DL, Wormhole

​
Bridge Aggregators

Routing protocols that aggregate across multiple underlying bridges to find optimal routes. Aggregator data is kept in separate tables to prevent double-counting when an aggregator interaction also emits a transfer from the underlying bridge. Protocols covered: Bungee, Jumper, LiFi

Crosschain Tables

The crosschain views aggregate all chain-level bridge data into unified tables for easy cross-chain analysis. See the schema reference for each category:

Bridges

Inbound and outbound transfers for application bridges (Across, DeBridge, Stargate, etc.)

Bridge Aggregators

Inbound and outbound transfers routed through aggregators (Bungee, Jumper, LiFi)

Messaging Protocols

Inbound and outbound messages from cross-chain communication layers (LayerZero, Wormhole, CCTP, etc.)

​
Legacy Table

The crosschain.bridges.transfers table provides a unified, deduplication-safe view of bridge activity using a net-single-directional approach. See Wormhole for the Wormhole-specific transfers table.
We are actively expanding bridge protocol and blockchain coverage. The new per-category inbound/outbound tables above supersede the legacy crosschain.bridges.transfers model for protocol-level analysis.
