H0.81 Capital

H081's vision is to become the private banking layer for all agents.
We've had a few questions about the Use Case for H081, who needs it and why, so we wrote an article. x.com/i/article/2118…

A lender needs to verify a loan’s conditions. Does that require seeing an agent’s entire private account?

With H081, the agent provides a zero-knowledge proof that verifies the required conditions without revealing its private balance or spending rules.

This video shows the lending flow on mainnet: open an offer, connect the borrowing agent and fund the loan.

Repayment comes from a configured share of the agent’s subsequent payments.

Loan amounts and settlement remain publicly verifiable. The underlying private account stays confidential.

That separation matters for businesses: giving an agent access to financing shouldn’t require exposing its entire financial position.

Watch the walkthrough below.

H081 has hit another milestone: nearly $2,000 in cumulative loan volume within our first 8 days.

A 400%+ increase since day 4

Since our previous update:

• Loan volume: $1,957.10
• Fully repaid loans: 41
• Transactions: 2,406
• ZK proofs verified: 531
• Private payments: 128

Our MCP and Solana Agent Kit packages also recorded 1000+ combined npm downloads across October 31–November 6, with over 300 each.

Through our startup applications, we’ve been joining community developer hubs and connecting with builders exploring H081. Those communities are helping drive interest, downloads and activity beyond our own development work and are becoming the core of our userbase

Some of this volume comes from people running their own fleets of agents, with multiple agents handling specific tasks. One builder can operate an entire team, each agent working within its own financial limits.

This is why we’re excited: private agent banking is running on mainnet, and more builders are discovering the tools to use it.

Much more to come

We’ve officially submitted our application to the @Hub71AD startup program.

Hub71 supports builders across AI, fintech and digital assets. H081 sits where those sectors meet: private financial accounts that let AI agents pay, manage budgets and borrow on Solana.

Our fit would be very practical. Teams building agents need a way to give them financial independence while protecting business information and enforcing spending limits. H081 provides that infrastructure through private allowances, zk proofs and published developer integrations.

Potential acceptance could help us turn those capabilities into an actual adoption:

• Integration partners: connect with AI startups that could bring H081 into their own agent products.
• Business pilots: reach corporate partners with real payment, budgeting and financial privacy requirements.
• Capital and guidance: access investor introductions and mentorship to support development and expansion.

In return, H081 would bring Hub71’s ecosystem working infrastructure that its builders could use, with lending and banking operations already demonstrated on mainnet.

The opportunity is to connect the teams building autonomous agents with the private financial tools those agents need.

Application submitted.

We proudly announce that H081 has officially been accepted into @sentry for Startups and awarded a $5,000 grant.

Looking forward to building with Sentry on our side 🤝

As agents use H081 to pay privately, manage budgets and lend to one another, reliability matters at every step. A failed tool call or slow relayer can interrupt the work those agents are doing.

@sentry helps developers identify software errors, trace failures across services and understand performance bottlenecks. That directly complements the private financial infrastructure we’re building.

We plan to use the funding to:

• Monitor errors across our app, relayer and agent integrations.
• Trace failed or slow banking requests to their source.
• Identify issues introduced by new releases and resolve them faster.

For H081, this supports more dependable banking workflows as usage grows. For Sentry, our stack provides a practical application of monitoring across autonomous agents and financial services.

Operational visibility should support financial privacy.

Our agents need infrastructure they can depend on. This helps us build it.
