Self-Custody Without the Seed Phrase: Bron and Noah Team Up on Stablecoin Access

Self-custody wallet provider Bron is partnering with stablecoin infrastructure company Noah to let users move money in and out of their wallets without leaving the app. The deal, announced June 25, pairs Bron’s seedless, MPC-based wallet architecture with Noah’s cross-border stablecoin rails, which already serve fintechs and exchanges in more than 70 countries.

Self-Custody Without the Seed Phrase: Bron and Noah Team Up on Stablecoin Access

Removing the Seed Phrase Bottleneck

Bron’s wallet uses a three-party MPC architecture to authorize transactions, splitting cryptographic signing material into three separate shards: one on the user’s device, one managed automatically by the Bron platform, and one held by an independent third party for recovery purposes only. No single party, including Bron itself, can reconstruct the complete signing material or move funds unilaterally. Transactions are authorized when the user signs on their device, which automatically triggers the platform shard to co-sign.

This design removes the 12- or 24-word recovery phrase that has functioned as the sole point of failure in most non-custodial wallets. The stakes attached to that single point of failure are well documented. According to estimates from the industry, up to 20 percent of bitcoin, which corresponds to about 3.79 million BTC, is lost permanently as a result of lost or misplaced seed phrases and other issues. The value of this lost bitcoin can be estimated at over $100 billion with the current market prices. An additional analysis released by Ledger estimates that as of Q1 2025, between 2.3 and 3.7 million bitcoins were permanently blocked from being accessed.

Academic research has also found that contingency planning around seed phrases is rare: a 2025 CHI Conference study of cryptocurrency users found that, despite understanding the importance of sharing seed phrases for emergency recovery, only 22% of survey participants had actually done so.

Brons architecture provides robust security against this single point of failure through a more complex architecture consisting of multiple protections such as biometric authentication, policy controls, delayed transfer of ownership, hidden vaults and redundant guardians.

The use of biometric authentication addresses one of the key weaknesses of the traditional seed phrase structure. Authentication mechanisms are based on physical characteristics of the user that fraudsters cant create a written record of, cant form a photograph of, and cant trick by creating a fake website using fake credentials, like they can with recovery phrases. The number of thefts caused by credential reveals and seed phrases represents one of the largest sources of loss to the asset class; one study estimated that close to 70 percent of the funds reported as stolen in 2024 came from lost keys/seed phrases.

Stablecoins as a Wealth-Management Entry Point

The partnership will also be focusing on targeting HNWIs that are increasingly allocating funds towards digital assets. Recent survey data shows the scale of this shift. Long Angle’s 2026 High-Net-Worth Asset Allocation Report, covering 233 respondents with an average net worth of $17 million, found that 42% of high-net-worth investors now hold crypto, surpassing the 39% who hold private equity funds. Among investors under 40, crypto represents 15% of their private and alternative portfolio allocation.

Regional data points to similar momentum. Sygnum’s APAC HNWI Report found that 87% of more than 270 surveyed high-net-worth and professional investors across ten Asia-Pacific markets already hold digital assets, with median holdings sitting in the 10% to 20% range and a weighted average near 17% of portfolios. Motivation has shifted accordingly. The same report found 90% of high-net-worth investors view digital assets as important for long-term wealth preservation and legacy planning, rather than short-term speculation.

“Stablecoins are becoming one of the most important bridges between traditional financial systems and digital assets,” said Shah Ramezani, Co-Founder and CEO of Noah. “Our mission is to expand access to the global financial system, and partnerships like this help make that vision tangible for everyday users. By combining Noah’s payments infrastructure with Bron’s innovative self-custody platform, we’re helping users participate in the digital economy with greater confidence and accessibility.”

Noah’s infrastructure is built around frequent cross-border movement characteristic of HNWI financial activities. Access to global dollar origination and payouts can be facilitated for high-net-worth individuals through the use of virtual accounts by the company. It operates in more than 70 countries and supports marketplace and international jurisdictions through blockchain-based payments, designed to be faster, less expensive and more transparent than traditional cross-border payment systems.

For HNWIs weighing custody risk against liquidity needs, the combination of MPC-secured recovery and direct stablecoin rails addresses two of the more practical objections to deeper crypto allocation: the operational risk of self-custody and the friction of moving fiat in and out of digital assets across jurisdictions.
