About H-Seal
H-Seal is the second product in the H-Series, a family of Hedera-native infrastructure tools built by XR Utilities. It provides cryptographic proof of task execution, service consumption, and result delivery for the agentic economy.
Every receipt is anchored on Hedera Consensus Service (HCS), giving it a tamper-proof, publicly verifiable consensus timestamp. Receipts are signed by the caller's wallet, so the identity binding is cryptographic rather than trust-based.
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.
Discovery. A capability registry for the agentic economy.
Execution proof. Cryptographic proof of execution.
Credential gating. Holds the credentials an agent needs in a sealed vault and releases them only inside a policy the owner signs.
Transport. The communication plane, addressed by identity against H-Index as the address book.
Behavior analytics. A universal multi-chain wallet behavior scanner.
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.
Egress control. Data-egress control for agents.
Standing and delegation. The standing and attestation layer.
Runtime identity. The runtime layer.
Use cases
Agent-to-agent interactions
When one agent delegates work to another, both parties get a verifiable record of the request, the result, and the timing.
MCP tool calls
Anchor a receipt every time an agent invokes an MCP tool. Build an immutable log of every tool call across your agent fleet.
API consumption tracking
Track which agents are calling which APIs, how often, and with what results. Useful for billing, monitoring, and capacity planning.
Compliance and audit
Maintain a verifiable audit trail that external auditors can check independently, without trusting any single party.
