Stablecoins have become a crucial component in bridging traditional finance with emerging on-chain economies. Despite their rapid evolution and significant role in digital finance, fragmentation remains a challenge. Over the past year, stablecoins have facilitated over $35 trillion in on-chain transfer volume, surpassing the combined annual volume of Visa and Mastercard. As the total stablecoin supply nears $225 billion, adoption is accelerating among both consumers and institutions.
New stablecoins are being launched across various blockchain platforms, including Ethereum, TRON, Solana, and the XRP Ledger. The number of active wallets has grown to 30 million, and business-to-business stablecoin flows now exceed $36 billion annually. Major corporations such as Mastercard, PayPal, Stripe, and Bank of America are integrating stablecoins into their payment systems to reduce costs and settlement friction. With over 25,000 merchants accepting stablecoin payments, the demand for efficient stablecoin infrastructure is increasing.
Orbital Pools: A New Era for Cross-Chain Liquidity
Despite the growth, users face challenges when swapping stablecoins across different chains due to the need for bridging and swapping, which incurs fees. Orbital Pools, utilizing THORChain’s native vault model and CosmWasm AppLayer, aim to address this issue by creating a unified, capital-efficient cross-chain liquidity pool. This innovation allows pooling of various stablecoins, such as ETH.USDC, TRON.USDT, and XRP.RLUSD, in a single orbital Automated Market Maker (AMM) while maintaining native-layer custody and composable execution.
Orbital Pools are inspired by Paradigm’s Orbital AMM and developed by the Rujira team. They extend Curve-style stablecoin AMMs to a cross-chain context, powered by THORChain’s Threshold Signature Scheme (TSS) vaults and AppLayer. This setup enables like-asset stablecoins to be pooled across chains efficiently, offering benefits to swappers, yield seekers, and developers.
THORChain-Powered Settlement and Orbital Curves
At the core of Orbital Pools are THORChain’s TSS vaults, which manage native assets across chains without wrapping or bridging. These vaults facilitate trustless and final settlement of trades, such as swapping USDC on Ethereum for USDT on Avalanche. Orbital Pools adopt orbital bonding curves, a generalization of Curve’s stableswap model, to maintain deep liquidity and low slippage near the peg.
Orbital AMMs introduce mechanisms for dynamic liquidity allocation along a price curve, allowing trades like USDC to RLUSD or USDT to DAI across different networks with minimal impermanent loss and slippage. Built on AppLayer, a modular smart contract orchestration layer on THORChain, Orbital Pools offer a highly composable architecture. This allows aggregators, wallets, and DeFi apps to integrate Orbital liquidity across chains without building cross-chain infrastructure themselves.
The development of Orbital Pools is progressing, with a soft launch anticipated in Q4 2025. More details can be found here.
