H0.81 Capital

H081 now live on mainnet. H081 is the first account that is private, provably-bounded, and lendable, all three at once.

H081’s private financial infrastructure now has on-chain evidence across its core banking operations, including a fully repaid private loan. All transactions are provable on-chain now. See txns below. Private deposits. Agent allowances. Payments. Zero-knowledge disclosures. Withdrawals. Capacity staking. Safety-pool deposits. And now: a private lending cycle completed from opening through full repayment on mainnet. The significance is privacy with verifiability. An agent can use its funds and prove specific financial conditions without giving counterparties access to its entire private account. Here are the mainnet receipts behind the system. → PRIVATE ACCOUNTS THAT AGENTS CAN USE USDG enters H081’s shielded pool. An agent receives a private allowance and can spend under the policy carried inside its note. A public payment shows its recipient and amount. It does not publish the treasury’s remaining private balance or its entire spending policy. Private deposit: solscan.io/tx/5tZ2AJXisuirk6… Agent allowance granted: solscan.io/tx/3MFurTW4kzTHbF… Agent payment: solscan.io/tx/3xfgjbADPbHVQD… → PROVE WHAT’S NEEDED. KEEP THE REST PRIVATE. A counterparty may need evidence that an allowance meets a minimum threshold. It does not need the exact balance or the complete account history. H081’s selective disclosure mechanism makes that distinction possible: a zero-knowledge proof establishes a specific condition, bound to a named audience. Here is a disclosure proof verified on-chain: solscan.io/tx/SeDth9QZ6Cv6xP… → ACCESS CAPITAL WITHOUT OPENING THE ENTIRE ACCOUNT Our first funded loan, Loan #2, has now been fully repaid. An agent pledged a share of its future payments. The lender verified the required stream conditions through a zero-knowledge proof, without receiving the agent’s full private balance or spending policy. The funding transaction settled: • 1 USDG from the lender. • 0.9975 USDG to the borrower. • 0.0025 USDG to the H081 treasury as the 0.25% origination fee. The borrower subsequently repaid the loan in full on-chain. A small-value demonstration, completing the cycle: Open → pledge → verify → fund → repay. Loan opened: solscan.io/tx/5xnZCvhPVjMihm… Agent pledged: solscan.io/tx/64v5vMhT2VVALW… Stream proof verified and loan funded: solscan.io/tx/4mrzBgZeCs5z3b… → WITHDRAW FROM THE SHIELDED POOL The banking flow also includes an executed withdrawal, moving funds out of the pool. Withdrawal: solscan.io/tx/4wLDLD27A62uAk… → TOKEN UTILITY, EXECUTED ON-CHAIN H081 capacity staking supports access to agent desks and shielded-volume capacity. The safety pool is designed to back covered lending risk. These transactions demonstrate staking and depositing into those programs. Safety-pool deposit: solscan.io/tx/5YvMo2PxReiHda… Capacity stake: solscan.io/tx/3JfUs3yhjAEhsg… → THE BIGGER PICTURE An agent should be able to pay a supplier without exposing its runway, demonstrate financial capacity without revealing its exact balance, and obtain financing without surrendering its entire private account history. That is what we’re building H081 around: private financial state, selective disclosure and publicly verifiable execution. These receipts document core operations on mainnet. Live on Solana.

H081’s private banking services are now available to AI agents through x402 on Solana.

After long days, weeks of hard work, we’ve just built and published H081’s own Solana Agent Kit plugin and MCP server on npm. Our very own packages: npmjs.com/package/@h081lll/s… npmjs.com/package/@h081lll/m… h081.xyz Developers can now connect our private USDG bank to their agents through two ready-to-use integrations. → SOLANA AGENT KIT PLUGIN Add H081’s deposit, withdrawal and loan actions to agents built with Solana Agent Kit. Agent Kit connects agents to Solana protocols. H081 adds private banking capabilities to those workflows, reducing the custom integration work needed to manage funds alongside other on-chain actions. → MCP SERVER Give MCP-compatible clients access to H081 through a standard tool interface. Developers can connect banking actions to their existing agent setup without writing a separate integration for every client. → SHARED CORE, CONSISTENT ACTIONS Both packages use the same underlying integration logic, keeping banking actions consistent across interfaces. The integration suite includes 60 tests (for devs). For developers, this shortens the path from “my agent needs a bank” to a working integration. For H081, it opens two routes to adoption: developers building with Solana Agent Kit and teams using MCP-compatible tools. Both packages are published at v0.1.0. Our upstream Solana Agent Kit PR is submitted, with acceptance pending. The pieces are coming together. The scale of what we’re building will become clearer with every release. Stay tuned.

We've officially submitted our application to Global Dollar Network, the network behind Paxos-issued USDG. @global_dollar Every agent using H081 brings USDG into the agent economy. We want that adoption to help fund the infrastructure behind it. H081 already gives agents a place to hold USDG privately, spend within defined limits and borrow against private cashflows on Solana. Global Dollar Network offers eligible partners rewards tied to USDG holdings and adoption. Connecting the two could give H081 another source of revenue as usage grows, alongside payment and loan origination fees. The opportunity runs both ways: • USDG gains distribution through agent applications integrating H081. • H081 could earn partner rewards from the USDG activity it supports. • Developers get private financial infrastructure built around the dollar their agents already use. Our application is submitted. Acceptance and reward eligibility are pending. We're building toward an agent economy where everyday financial activity helps sustain the infrastructure it depends on. h081.xyz

Privacy should never come at the cost of access to your funds. H0.81 is making withdrawals from private treasuries possible on Solana mainnet, with transactions that can be independently verified. Our latest walkthrough shows the process in action: • 5 USDG is withdrawn from a private treasury. • Funds are transferred directly to the connected Solana wallet. • The transaction is confirmed onchain and recorded on Solscan. • The public withdrawal record shows the amount and recipient, while the remaining private treasury balance is not disclosed. H0.81 protects financial information within the private treasury while maintaining transparency when funds move back into public wallets. Private financial infrastructure should give users both confidentiality and the freedom to access their money.
