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 to access the dashboard and developer tools.
2. Read the documentation: See the 0xGasless docs for installation guides, API references, and integrations.
3. Fund the paymaster: Follow the guide and use the dashboard 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.

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.
