# Interchain Messaging (ICM) & Teleporter

> Trustless cross-chain liquidity and collateral routing powered by Avalanche Warp Messaging.

## Trustless Cross-Chain Liquidity

Traditional bridges rely on multi-sig committees or wrapped token custodians that represent single points of failure.

Nyxor uses **Avalanche Interchain Messaging (ICM)** and **Teleporter**, where messages are validated directly by the consensus layer using aggregated BLS validator signatures under **ACP-77**.
