Solstice and Cor Prime Execute First Institutional Stablecoin-for-Stablecoin Repo on a Public Blockchain

[PRESS RELEASE – Zug, Switzerland, December 23rd, 2025]

The transaction was settled and serviced through Membrane’s post-trade credit infrastructure and executed under a GMRA and Digital Asset Annex, establishing the first standardized stablecoin funding market on public blockchains.

Solstice Labs, Cor Prime, and Membrane Labs today announced the successful completion of the first institutional stablecoin-for-stablecoin repurchase agreement (Repo) executed under traditional market documentation and settled on a public blockchain. The transaction marks the creation of a standardized, institutional-grade stablecoin funding market that brings familiar TradFi liquidity tools directly onto public blockchain rails.

The repo was executed bilaterally under a Global Master Repurchase Agreement (GMRA) and Digital Asset Annex, with asset and cash legs transferred directly between institutional wallets on Solana and Ethereum. Membrane’s institutional post-trade credit infrastructure provided on-chain settlement, servicing, and lifecycle management, enabling cross-chain movement of assets with full ownership transfer and repo-style unwind.

This structure represents the first time a native stablecoin has served as the asset leg in an institutional repo. Solstice posted its native stablecoin, USX, as the asset leg, while Cor Prime provided USDC as the cash leg. The two legs will unwind at maturity at a price reflecting the agreed-upon repo rate. Unlike smart-contract lending pools, this transaction mirrors the legal, operational, and economic mechanics of traditional repo markets.

A New Funding Primitive for Stablecoins

Stablecoins vary widely in liquidity, regulatory treatment, and institutional adoption. Until now, issuers and traders have lacked the funding tools used in traditional markets to source liquidity, defend pegs, or access short-term financing without selling inventory. Overcollateralized loans and automated lending pools have been the only available models, neither of which resembles institutional repo structures.

By enabling USX to be financed against USDC through a standardized repo, Solstice gains new flexibility in balance sheet management and peg resilience. The structure also opens new avenues for investors to earn structured returns using market mechanics they already understand.

New Institutional Infrastructure for Onchain Credit Markets

Membrane provided the post-trade credit infrastructure required to execute, margin, settle, and service the repo across chains. Its platform enables institutions to transact using familiar legal documentation while benefiting from the speed and finality of public blockchain settlement.

Cor Prime supplied the institutional liquidity required to make the repo functional, acting as the OTC counterparty and enabling the first cross-chain repo settlement between stablecoins on a public network.

A Foundation for a Stablecoin Funding Curve

The successful completion of this transaction establishes the basis for a true funding market for stablecoins across public blockchains. As this structure evolves, issuers will be able to manage liquidity more effectively, market makers will gain access to stablecoin financing aligned with institutional standards, and investors will be able to earn repo-style returns backed by digital assets.

This is the first step toward a standardized stablecoin funding curve, bringing repo-style financing — one of the most important liquidity mechanisms in global markets — into the digital asset ecosystem.
