Onramp Debuts Corporate Bitcoin Accounts Requiring Two Signatures for Withdrawals Amid Attack Surge

On Tuesday, Onramp introduced Onramp Business, a no-cost corporate account featuring designated users, permission-based roles and a two-person approval requirement for withdrawals. The launch comes as physical assaults on bitcoin holders increased during the first six months of the year.

The Austin-based company unveiled the offering for businesses seeking to hold bitcoin on their balance sheet but hesitant to rely on a single login, custodian or keyholder. The basic account charges a 0.85% trading fee, stores bitcoin with a qualified custodian, and typically gets approved within one business day. It accommodates as many as three users, with owner, admin and view-only roles along with an audit trail. Two additional service levels, Onramp Treasury and Onramp Enterprise, were introduced at the same time.

“We spent years watching businesses decide they wanted bitcoin on the balance sheet, then stall the moment their board asked who holds the keys,” said Michael Tanguma, founder and CEO of Onramp. “Nobody had a good answer. Onramp Business gives a company the same controls its bank account already has: named users, approvals on withdrawals, and a record of everything. As the position grows, Onramp Treasury holds it in a vault protected by three independent institutions, so no single party, Onramp included, can lose or move it.”

A report covering the first half of 2026 documented 52 physical assaults on bitcoin and cryptocurrency holders, a 33% increase compared to the prior year. The financial exposure linked to these events climbed to roughly $124 million from $10.5 million. The report observed that any individual capable of moving coins unilaterally could be compelled to do so under coercion.

What the free account does and does not include

Onramp Business does not itself constitute Multi-Institution Custody. According to the company’s product page, bitcoin in the no-cost account is held in cold storage with a qualified custodian. Multi-Institution Custody is available via Onramp Treasury, priced from $375 per month, or $3,600 annually. It reduces the trading fee to 0.65% and transfers the coins to a vault under the company’s name.

The vault is safeguarded by a 2-of-3 quorum involving Onramp, Tetra Trust and CoinCover, ensuring that no one institution can lose, transfer or utilize the bitcoin. Treasury accommodates up to five users and two vaults, and offers migration assistance and continuity planning for changes in leadership. An onboarding fee of $500 is waived for firms that activate Treasury before Dec. 31. Onramp Enterprise, targeting funds, miners and large corporate treasuries, is priced individually via consultation.

Since 2023, Onramp has provided Multi-Institution Custody for both individuals and institutions, with a network that additionally includes BitGo. In May, the company raised $12.5 million in a Series A round at a $135 million valuation, stating it manages over $1 billion in bitcoin under this model without any security breaches since its founding. Onramp also introduced Onramp Finance in April, which combines cash accounts, bitcoin brokerage, IRAs and gold.

A crowded treasury trade, and a key-person problem

Publicly traded companies have adopted bitcoin as a balance-sheet asset to a degree that would have been uncommon just a few years back. Strategy (MSTR), the biggest corporate holder, currently possesses 850,364 bitcoin following its most recent weekly acquisition. For smaller enterprises, the more difficult issue has frequently been operational: who controls the keys, what occurs when that individual departs, and whether one compromised credential or one coerced worker can transfer the entire holding.

According to the announcement, Pacific Office Designs and Build Collateral Agent are already employing Onramp for their corporate bitcoin.

“As collateral agent for credit funds using bitcoin as collateral, Build Collateral Agent, LLC selects partners based on a number of risk mitigation considerations, including our attempt to eliminate single points of failure,” said John Ruth, president of Build Collateral Agent, LLC. “Onramp Business uses a differentiated approach with their multi-institutional security model that is aligned with our risk mitigation philosophy. Onramp’s service model has exceeded our expectations. Team members and leadership are available to us when we need them – providing valuable human connections to a tech savvy product suite.”

The question now is whether boards that favored the asset but declined the custody options will regard the two-person approval requirement and the three-institution vault as a sufficient solution.
