| -------------------- | -------------------------------------------------------------------------------------------------------------------------- |
| **Agent Wallet**     | ShredPay's product giving AI agents a sandboxed on-chain wallet.                                                           |
| **Sub-wallet**       | A user-owned wallet dedicated to a single agent / use case. Distinct from the user's main ShredPay wallet.                 |
| **API key**          | The credential that grants access to one sub-wallet, with permissions and spend limits attached.                           |
| **Co-signer**        | ShredPay's P-256 key that participates in the 2/2 quorum signing scheme.                                                   |
| **Privy**            | The wallet infrastructure provider that holds the other half of the 2/2 quorum.                                            |
| **Router**           | ShredPay's on-chain contract that batches approve + swap + deposit and lets ShredPay sponsor gas.                          |
| **MCP**              | [Model Context Protocol](https://modelcontextprotocol.io/) — the open standard ShredPay uses to expose tools to AI agents. |
| **OpenClaw**         | An agent platform that ships ShredPay as a one-click installable Skill.                                                    |
| **Skill (OpenClaw)** | A bundled set of tools and metadata an agent can install. ShredPay's Skill is `shredpay-wallet`.                           |
| **Sponsored gas**    | Gas paid by ShredPay (in exchange for a small service fee). Available for swap, DeFi, and `gas_swap`.                      |
| **Allowed chains**   | The whitelist on an API key — only listed chain IDs may be used.                                                           |
| **Group ID**         | An optional grouping of sub-wallets under a user. Reserved for future multi-wallet workflows.                              |
| **Quorum**           | A signing scheme that requires multiple signatures. ShredPay uses 2/2 (Privy + ShredPay co-signer).                        |
| **Smallest unit**    | The integer representation of a token amount (e.g. 1 USDC = `1000000` because USDC has 6 decimals).                        |
