CDP Onchain Tools gives you infrastructure-level access to everything below the application layer: sponsor gas for your users, query onchain data at scale, equip AI agents with wallet capabilities, and fund testnet accounts during development.

Tools at a glance

Paymaster

Sponsor gas fees on behalf of your users. Works with ERC-4337 smart accounts on Base to create gasless experiences without users needing ETH.

Data

Query and monitor onchain data with sub-500ms latency. Includes a SQL API, RPC node access, token balances, wallet history, and real-time webhooks.

AgentKit

A toolkit for giving AI agents onchain capabilities — transfers, swaps, contract deployments, and more — using any AI framework.

Faucet

Claim testnet tokens for Base Sepolia, Ethereum Sepolia, and Solana Devnet during development.

Choosing the right tool

Eliminate gas friction for your users. Use Paymaster to sponsor ERC-4337 smart account transactions on Base so users never need to hold ETH. Read or monitor onchain state. Use Data to query balances, transaction history, or live events via SQL, RPC, or webhooks — no node infrastructure required. Add wallet capabilities to an AI agent. Use AgentKit to let your agent sign transactions, execute swaps, and deploy contracts using any AI framework (LangChain, Vercel AI SDK, etc.). Get testnet tokens for development. Use the Faucet to claim ETH, ERC-20, or SPL tokens on Base Sepolia, Ethereum Sepolia, and Solana Devnet.
