Overview
What is Wax Seal?
Wax Seal is a cryptographic identity infrastructure for AI agents. Each seal is an Ed25519 keypair minted on-chain (Base, Ethereum, or BNB Chain), giving agents a tamper-evident way to verify identity, authenticate documents, and enforce human approval before executing irreversible actions.
How to use Wax Seal?
Use the provided MCP tools: call waxseal.info first, then use waxseal.identity.verify, waxseal.signature.verify, or waxseal.approval.verify. For signing documents or creating approval tokens, set the WAXSEAL_PRIVATE_KEY_PEM environment variable. The verify-only tools require no configuration.
Key features of Wax Seal?
- Ed25519 keypair minted on-chain (Base, Ethereum, BNB Chain)

- Auditing agent actions via on-chain cryptographic proofs
FAQ from Wax Seal
What is a WaxSeal?
A WaxSeal is an Ed25519 keypair minted on a blockchain (Base, Ethereum, or BNB Chain), providing a cryptographic identity for AI agents.
Do I need a private key to use all tools?
No. The first four tools (info, identity.verify, signature.verify, approval.verify) require no private key. Only waxseal.document.sign and waxseal.approval.create need the WAXSEAL_PRIVATE_KEY_PEM environment variable.
How does human-in-the-loop approval work?
The agent creates an approval token via waxseal.approval.create, stores it, and before executing an action calls waxseal.approval.verify with the token. The action proceeds only if verification returns valid.
Where can I get a WaxSeal?
You can create a seal at waxseal.id/create.

Do I need a private key to use all tools?
No. The first four tools (info, identity.verify, signature.verify, approval.verify) require no private key. Only `waxseal.document.sign` and `waxseal.approval.create` need the `WAXSEAL_PRIVATE_KEY_PEM` environment variable.
How does human-in-the-loop approval work?
The agent creates an approval token via `waxseal.approval.create`, stores it, and before executing an action calls `waxseal.approval.verify` with the token. The action proceeds only if verification returns valid.
