# 0xGasless (/integrations/0xgasless)

## Overview

0xGasless AgentKit is an SDK for on-chain execution by AI agents, covering transaction signing, smart contract interaction, token swaps, contract deployment, and wallet management — all without gas.

It supports the x402 Payment Protocol with the 0xGasless x402 Facilitator service (https://x402.0xgasless.com/) for the Avalanche Chain open payment standard.

It also includes a full account abstraction stack on ERC-4337 and ERC-7702, so developers can build dApps with gasless transactions, batching, and session keys.

## What we are offering

0xGasless offers an x402 Facilitator for the on-chain open payment standard and an AI AgentKit for gasless smart accounts and autonomous on-chain AI agents via ERC-4337, with paymasters, bundlers, and LLM-ready tools across EVM chains.

## C‑Chain (Avalanche) notes:

- **Native gas token**: AVAX (sponsored mode requires a funded paymaster).
- Many stablecoins (e.g., USDT) use 6 decimals, format amounts correctly.
- Ensure your API key is enabled for 43114 and that your paymaster gas tank is funded.


## Getting Started

1. **Sign up**: Create an account on the [0xGasless Platform](https://dashboard.0xgasless.com/) to access the dashboard and developer tools.
2. **Read the documentation**: See the [0xGasless docs](https://docs.0xgasless.com/) for installation guides, API references, and integrations.
3. **Fund the paymaster**: Follow the [guide](https://docs.0xgasless.com/Getting%20Started/create-a-page) and use the [dashboard](https://dashboard.0xgasless.com/) to create and fund the paymaster.
4. **Integrate the SDK**: Obtain API keys and configure the smart account, bundler, and paymaster using the SDK [docs](https://docs.0xgasless.com/Getting%20Started/create-a-page#step-1-obtain-required-api-keys).
5. **Explore modular options**: The SDK is modular; customize each step of the account abstraction cycle as needed.
6. **Test and deploy**: Use multi-chain support, test thoroughly, and keep the paymaster gas tank funded.

## **Use Cases**

- **Autonomous Agent Services**: Deploy an AI agent (like a data-eval agent or a code reviewer) that charges other agents via x402 to perform a task, such as fine-tuning a model or verifying a pull request.
- **Monetizing Your APIs**: Automatically charge other users or agents a small fee (e.g., $0.001) every time they call an API endpoint you've deployed.
- **Pay-Per-Query Dashboards**: Build and host a DeFi savings dashboard or an analytics tool that charges users a micro-payment for each new query or data refresh.
- **AI Agents**: Streamline payment processes with smart accounts. Account abstraction provides a secure infrastructure for agents interacting with money.
- **DeFi Applications**: Improve accessibility and usability with gasless transactions and easy onboarding.
- **Enterprise Applications**: Manage complex access controls and transaction rules with scalable, secure integrations.
- **Crypto Wallets**: Develop wallets using smart accounts for improved security, usability, and gasless transactions.
- **Digital Identity Management**: Manage digital identities with customizable transaction and access rules for secure, scalable identity.
- **Blockchain Games**: Onboard users via social logins to manage in-game assets and progress.
- **NFT Marketplaces**: Let users interact with platforms using their existing social accounts to improve acquisition and engagement.
