About H-Gate

H-Gate is a product in the H-Series, a family of Hedera-native infrastructure tools built by XR Utilities. It provides data-egress control for agents. Outbound payloads pass through a policy that decides what an agent may send to which destination; blocked, redacted, and allowed sends are recorded. It answers one question: what is this agent allowed to send out, and can you prove what left?

You can gate the egress of any agent against any destination on its own. A deterministic engine flags identifiers, financial accounts, crypto addresses, provider tokens, secrets, and keys, then applies your policy: allow, redact, or block. Every decision can anchor to H-Seal for proof of what left and what was held back. A denied send also emits a risk signal onto the shared H-Series audit topic, where it feeds the sending agent's H-Cert standing.

Part of the H-Series

Nine complementary but independent products for the agentic economy. Each can be used on its own or composed with the others.

H-Index

Discovery. A capability registry for the agentic economy.

H-Seal

Execution proof. Cryptographic proof of execution.

H-Grant

Credential gating. Holds the credentials an agent needs in a sealed vault and releases them only inside a policy the owner signs.

H-Relay

Transport. The communication plane, addressed by identity against H-Index as the address book.

H-Scope

Behavior analytics. A universal multi-chain wallet behavior scanner.

H-Pact

Membership. A registry of signed, on-chain membership rings: bounded groups of agents, MCP servers, and API services that have agreed to operate together under shared, owner-signed rules.

H-Gate

Egress control. Data-egress control for agents.

H-Cert

Standing and delegation. The standing and attestation layer.

H-Agent

Runtime identity. The runtime layer.

Use cases

Outbound API calls

Inspect the payload an agent is about to send to a third-party API and redact or block sensitive fields before they leave the boundary.

Agent-to-agent messages

When one agent hands data to another, gate the message against your policy so nothing sensitive crosses without a decision.

Context fetches

Control what an agent pulls into context, so secrets, keys, and PHI do not travel to a destination that should not receive them.

Compliance and audit

Every redact or block is anchored as an H-Seal receipt, so auditors can verify what was held back without trusting any single party.
