# Wallet Infrastructure

Onyx AI Agent's Blockchain Wallet Infrastructure

## AI Agent Wallet Architecture

Each instance of Onyx AI is provisioned with a dedicated on-chain wallet, referred to as an agent wallet. These wallets are permissionless and have no centralized control. These wallets serve as the execution layer for autonomous tasks. Users can:

* Fund the agent wallet with any ERC20 token or Ethereum on Onyx, Ethereum, Base, and BNB Chain.
* Predefine operational rules (e.g., budget limits, whitelisted dApps, risk thresholds).
* Allow the agent to execute autonomously within those constraints, using AI to interpret prompts and derive task sequences.

Wallets are deterministic, derived via cryptographic hashing of user identifiers and secured by permissionless layers that enforce non-custodial ownership. Additionally, agent wallets can integrate time locks, multisig guards, and circuit breakers to ensure execution safety.

### Deployment Environment and Ecosystem Integration

* Blockchain: Onyx, Ethereum, Base, BNB
* Gas Token: Onyx transactions incur network fees paid in XCN. Where the agent presents a gasless experience, the fee is sponsored or abstracted through `Credits`; the underlying network fee is not eliminated. See [Network Fees](/developer-guide/network-fees.md).
* dApp Support: Onyx AI is extensible and continuously updated with support for top-tier dApps in categories including DeFi, NFT marketplaces, staking, and governance.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.onyx.org/onyx-ai/wallet-infrastructure.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
