At Bifrost, we’re advancing a vision where liquid staking seamlessly integrates into every blockchain interaction—invisible yet everywhere. Our SLPx architecture has been pivotal in transforming this vision into reality for ASTR liquid staking, enabling frictionless cross-chain experiences while expanding vASTR’s liquidity and utility.

Igniting Demand with Astar’s Partnership with Soneium

The journey accelerated on December 18, 2024, when Astar Network’s Surge event introduced a collaborative rewards pool with Soneium. By allowing users to stake ASTR or vASTR directly within decentralized applications, demand surged organically: Total value staked of vASTR(TVS) grew by 25% in one week, climbing from 40M to 50M.

This momentum intensified on January 14, 2025, with Soneium’s mainnet launch. Cross-chain interoperability became effortless, and vASTR’s minted volume doubled to 100M within weeks.

By February 4, 2025, the integration of Stargate UI further abstracted technical barriers, enabling smooth asset transfers between Astar zkEVM and Soneium. Users could now focus on earning rewards—not managing chains.

The Silent Engine Behind Growth – SLPx

The invisible force driving this expansion? Bifrost’s SLPx—a cross-chain liquid staking framework designed to eliminate complexity.

Traditional cross-chain staking often requires manual asset bridging, multiple transactions, and fragmented interfaces. SLPx redefines this by allowing users to mint, redeem, and manage vASTR across chains as if operating on a single network. Its remote call function acts like an "invisible bridge," abstracting cross-chain processes into a unified experience.

For example:

• Before SLPx: Transfer ASTR → Bridge to Bifrost → Stake → Bridge vASTR back.
• With SLPx: Stake ASTR directly on Soneium → Receive vASTR instantly.

By making cross-chain interactions feel native, SLPx has unlocked higher liquidity, simpler DeFi integrations, and accelerated adoption across ecosystems.

Invisible Infrastructure, Visible Impact

vASTR’s growth—from 40M to 100M in under two months—isn’t just a metric. It’s proof that liquid staking thrives when complexity disappears. Bifrost’s SLPx architecture embodies our commitment to making staking effortless, interoperable, and invisible, empowering users to focus on what matters: maximizing capital efficiency.

Liquid staking won’t just be everywhere—it’ll feel like it’s nowhere, quietly powering the future of multi-chain DeFi.
