Protect Your AI Agents with PAVii.AI
Blockchain-based security and observability for every AI agent and LLM. Pavii blocks harmful calls, keeps personal data private and records every action on Hyper 0X.
Pavii is under development.
Security for the Age of AI Agents
AI agents read data, call tools and send messages for you. Pavii checks each of these actions, stops the harmful ones and shows your team what every agent does.
Six Security Gates
Pavii checks every agent call at six gates: injection, privacy, supply chain, budget, egress and output. Pavii blocks a bad call before it can do harm.
Private Data Stays Private
The privacy gate removes personal data and secrets before a model sees the prompt. Zero-knowledge proof designs let a provider check a fact without seeing the data.
Rules on the Blockchain
Pavii keeps your important rules as smart contracts on Hyper 0X. The rules still apply when a model forgets an instruction in a long chat.
Agentic Observability
See each call, tool, blocked action and cost for every agent. Each receipt links to the one before it on Hyper 0X, so nobody can secretly change the record.
How Pavii works
Every agent call is checked at six gates
Safe calls go on to your tools. Harmful calls go to the shredder. Each decision prints a receipt on Hyper 0X. Select a label or a step to see what each part does.
Pavii runs on Hyper 0X, the post-quantum-resistant blockchain from Buckleson. See how Hyper 0X works.
Use any AI in your applications. PAVii.AI protects it.
How Pavii decides
Watch Pavii decide, one call at a time
Real kinds of calls from coding and office agents. A hidden instruction, an unknown MCP server and a bulk email stop at their gates. The rest reach the end with a signed receipt.
- 01 One gateway, every agent Every prompt and tool call from every agent comes in through one entry point, so each call has a known sender. ClaudeCodexChatGPTCustom
- 02 Injection gate Text from web pages, files, emails and tool results is data. Pavii never runs it as an instruction. Hidden promptsJailbreaks
- 03 Privacy gate Pavii removes personal data, keys and secrets before a model sees them. Personal dataAPI keys
- 04 Supply-chain gate New packages, plug-ins and MCP servers must be on the allow-list, match a pinned hash or pass a sandbox test. MCPPackages
- 05 Budget gate Each agent has limits on tokens, spend and call rate. TokensSpendLoops
- 06 Egress contract A smart contract on Hyper 0X decides what an agent can send and do. Nobody can secretly change it. On chainApprovals
- 07 Output gate Pavii removes scripts, secrets and system-prompt text from what the agent returns. ScriptsSecrets
- 08 Kill switch An agent that breaks rules moves from observed, to restricted, to stopped. A person can stop any agent. ObservedRestrictedStopped
- Signed receipt on Hyper 0X Pavii links each decision, allowed or blocked, to the decision before it. A deleted entry shows as a gap.

Frequently
asked questions
PAVii.AI is a blockchain-based security and observability platform for AI agents and LLMs. Pavii checks every agent call, blocks harmful actions and records what each agent does. Buckleson builds Pavii on Hyper 0X, its own post-quantum-resistant blockchain.
Pavii keeps important rules as smart contracts on Hyper 0X. A smart contract is a program on the blockchain that nobody can quietly change. An egress contract decides what an agent can send and do. Pavii links each receipt to the one before it, so nobody can secretly change or delete a record.
The privacy gate removes personal data and secrets before a model sees the prompt. Pavii also uses zero-knowledge proof (ZKP) designs. A ZKP lets one party prove a fact without showing the data behind it. Model providers can learn from usage, but they do not get data that can harm you.
Pavii is one gateway for any AI agent or LLM. It works with Claude, Claude Code, Codex, ChatGPT, Grok, OpenCode and your own custom agents. You can build new agents in Pavii or connect the agents that you use now.
The kill switch moves the agent from observed to restricted to stopped. Pavii blocks the harmful call, or at least makes it visible to your team. A person can stop any agent at any time.
The company brain is a shared memory that Pavii builds from usage, as a graph of your products, people and knowledge. Pavii checks each request for access on the blockchain. So the agent of a junior employee cannot read restricted knowledge, even inside the shared brain.
Yes. You can use the Pavii chain, run your rules on-chain or deploy your own chain inside your organization. Pavii can also connect to the platforms that you use now. You do not need to change your business logic.
Agentic observability shows how your agents behave: each call, each tool, each blocked action and the cost. Your team can use this record to find problems and make agents better.
