Cayman Court Steps Into the DeFi Arena as Core Foundation and Maple Finance Clash Over Bitcoin Yields

A high-stakes dispute between Core Foundation and Maple Finance has escalated into a landmark legal confrontation after the Cayman Islands Supreme Court issued an injunction restricting Maple from launching a competing Bitcoin performance product. The order, handed down while arbitration proceeds, bars Maple from deploying its proposed syrupBTC token, using Core’s confidential information, or trading CORE tokens without written approval. The ruling signals an important moment for the maturing DeFi sector, where intellectual property, commercial exclusivity, and custody structures are becoming increasingly contested.

The court determined that a “serious matter” required judicial scrutiny, focusing on whether Maple breached its commercial agreement with Core after the two organizations had partnered to build lstBTC, a liquid staking Bitcoin token unveiled in early 2025. Designed to offer yield while keeping user assets safely held by custodians such as BitGo, lstBTC was positioned as a low-risk, institution-friendly entry point into Bitcoin yield strategies. Core invested heavily in marketing, development, and grants, while Maple—managing less than $500 million in assets at the time—served as a co-developer.

According to Core, the alliance began to unravel in mid-2025 when Maple allegedly used confidential resources to build a rival product, syrupBTC, despite a 24-month exclusivity clause. Core also noted that Maple had already received over $150 million in lender-supplied Bitcoin for an OTC pilot of the BTC Yield product, funds that were supposed to be protected through an isolated, bankruptcy-remote structure. In Core’s view, the combination of alleged contract violations and exposure of lender assets demanded immediate judicial intervention.

“We honored the expiration of all put options for months, paying millions, until Maple allegedly grossly breached its obligations,” Core stated, arguing that the injunction was necessary to prevent Maple from gaining early market advantage through unauthorized use of confidential materials. Judge Jalil Asif KC’s ruling underscored this position, noting that monetary damages alone would be insufficient given the potential competitive harm if Maple advanced syrupBTC while arbitration remained unresolved.

Maple Finance has pushed back strongly. The company insists the dispute affects only the BTC Yield pilot and maintains that its broader operations remain intact. Maple argues that Core’s legal maneuvers “directly harm the interests of lenders,” rejecting allegations of misconduct and vowing to pursue legal remedies to hold Core accountable.

The confrontation has rattled lenders and market observers. Core has raised particular alarm over Maple’s recent comments about possible impairment to lender-held Bitcoin—claims Core argues undermine the very safeguards that segregated custody structures were meant to provide. Core reiterated that lstBTC’s risk-mitigation design included put options to cushion volatility and emphasized that it had honored these obligations for months before seeking legal protection.

The market response has been swift. Maple’s total value locked plunged by $107 million following the announcement, a sharp contraction for a protocol that had long positioned itself as a specialized institutional credit platform. Yet in an unusual twist, the protocol’s net profit turned positive—exceeding $95,000—for the first time since launch, underscoring the volatility and contradictions of DeFi protocols navigating legal uncertainty.

As arbitration progresses, the case stands to shape how courts interpret confidentiality, exclusivity, and custody obligations in decentralized finance. With Bitcoin-based yield strategies growing more sophisticated, the ruling in this dispute may become a touchstone for legal standards governing the next generation of on-chain financial products.
