River Launches Chain-Abstraction Stablecoin System Connecting Liquidity Across Ecosystems

Singapore, Singapore, August 14th, 2025, Chainwire

River is building a chain‑abstraction stablecoin system that lets users deposit collateral on one chain and mint the omni‑chain stablecoin satUSD on another—without bridging or wrapping. The result is native access to yield and leverage across ecosystems, without selling underlying assets.

Liquidity Fragmentation in the Multi-Chain Era

Over the past two years, crypto have expanded into a multi‑chain landscape:

  • 300+ Layer2 networks
  • 30+ stablecoins
  • 20+ LSDs/LSTs based on BTC and ETH

Despite this growth, liquidity remains fragmented across isolated chains. Running a single strategy—say, collateralizing ETH on Arbitrum while holding BNB on BNB Chain—often requires multiple bridging steps and DEX swaps, raising costs and operational risk. More chains have created optionality, but not systemic capital efficiency.

River’s Chain‑Abstraction Stablecoin System

Most stablecoins are anchored to single chains and rely on third‑party liquidity when moving across networks. River takes a third path—chain abstraction: hide chain boundaries so users provision capital once and deploy it anywhere.

Built on LayerZero and the OFT standard, River enables:

  • Collateral deposits in BTC, ETH, BNB, and LSTs on supported chains
  • Native minting of satUSD on a destination chain
  • Movement of liquidity without bridges or wrapped assets, with security preserved end‑to‑end

It can be described as a global on-chain account—accessible across ecosystems without re-creating accounts or re-establishing positions on every network.

Product Traction

River’s product is live and scaling rapidly. In the past two months, its chain-abstraction stablecoin system has achieved:

  • $400M+ in total value locked (TVL)
  • $100M+ satUSD in circulation
  • Collateral support for BTC, ETH, BNB, and LSTs
  • Integrations with 30+ protocols, including Pendle, ListaDAO, and Solv
  • #1 CDP stablecoin ranking in ecosystems such as BNB Chain, Arbitrum, Hemi, and BOB

Wherever assets reside, River can activate them across strategies and ecosystems without friction.

Why Now

DeFi TVL now exceeds $150B, with stablecoins at $270B in market cap.

Yet the market still faces:

  • Fragmented liquidity across chains
  • Slow, costly asset transfers
  • Yield concentration in top protocols
  • Complex onboarding for new users

As more DeFi protocols, stablecoin issuers, and public companies launch their own Layer1s and Layer2s, liquidity risks are becoming even more siloed. River’s chain-abstraction stablecoin is built to connect ecosystems, not add another isolated chain.

Chain-Abstraction Stablecoin

Connecting Liquidity and Value Across Ecosystems

River isn’t simply another stablecoin. It is built on a natively omnichain architecture designed to change how assets move and interact across chains.

Ethena’s hedging strategy, Liquity’s liquidation model, or Usual Money’s minting mechanism can be forked; however, the chain-abstraction architecture that underpins River cannot be replicated in the same way.

Most stablecoins were never designed to solve the integration of cross‑chain capital, liquidity, and yield. satUSD was engineered from day one as an omni‑chain asset, deployed with LayerZero technology and the OFT standard. This approach currently has no comparable solution in the market.

The process is instant. Without bridges or wrapped tokens, transactions move across chains like early peer-to-peer crypto payments and settle faster than bank wire transfers.

River’s ambition goes beyond issuing a stablecoin. Its aim is to let any asset, anywhere, take part in value creation, distribution, and circulation — instantly, securely, and without friction.

To connect with value. Flow with River.

About River

River is building a chain abstraction stablecoin system that enables cross-chain collateral, yield, and liquidity, all without bridging. Powered by the omni-CDP stablecoin satUSD, users can earn, leverage, and scale across different ecosystems natively. 

River features the first omni-CDP module that allows users to collateralize assets on Chain A and mint stablecoin satUSD on Chain B — without bridging the assets.
