Open USD’s Partner List Included Firms That Never Agreed to Join

Open USD launched on June 30th billing itself as a serious challenger to USDT and USDC, with a partner list exceeding 140 names including Visa, Mastercard, BlackRock, Coinbase, and more than a dozen South Korean financial institutions. Within days, several of those Korean firms publicly denied any formal involvement.

Samsung Electronics told local outlet Chosun Biz there had been “no official consultations” and that the company did not know what role it would play in the consortium. Dunamu, Shinhan Financial, and K Bank offered a slightly softer version: Open Standard had asked if they were interested, and they had replied only with a willingness to review the proposal. That is meaningfully different from being a partner. One unnamed company official said they were “perplexed to be included as a member,” having learned of their listing through domestic news coverage. The stablecoin sector has a long history of announcements that outrun their actual substance, but listing major financial institutions as partners without their knowledge is a different category of problem, closer to misrepresentation than optimism.

Circle fell over 15% on the day of the announcement. That move now looks like a market pricing in a threat that may not exist at the scale advertised.

The partner list was the entire story with Open USD. Without it, the consortium is an unproven stablecoin issuer competing in a market where USDC and USDT have years of liquidity depth, regulatory familiarity, and real institutional integration. Circle CEO Jeremy Allaire was pointed in his response, confirming on X that the Coinbase partnership remains intact and posting simply “Integrity matters” as the Korean denials surfaced. Coinbase’s appearance on the Open USD list had fueled speculation about its relationship with Circle, which the two companies have built into a core distribution mechanism for USDC. That speculation appears premature at best.

For the stablecoin market broadly, the episode raises a practical question about how new entrants establish credibility when the primary signal investors use is institutional backing. If that backing can be implied through a press release before firms have formally committed, the signal degrades for everyone. Regulators in multiple jurisdictions are currently working through stablecoin frameworks, and incidents like this give them additional reason to require verified, documented partner relationships rather than announced ones.
