Features
Circle’s blockchain infrastructure simplifies key aspects of blockchain interactions by offering the following features:Broadcasting
For transactions signed on Circle’s platform, the platform handles broadcasting to the blockchain. You can also use Circle’s Signing APIs to integrate with your preferred node service providers for broadcasting, offering flexibility and control.Indexing
Reading directly from blockchains often results in high latency, which can negatively impact the user experience. Circle addresses this by:- Indexing all inbound and outbound transfer events and wallet balances in real time.
- Providing access to blockchain data via low-latency APIs, simulating the performance of a fast database.
- Offering webhook notifications for deposits and withdrawals to keep you informed of wallet balance changes.
Gas Station
Circle’s Gas Station simplifies the management of native tokens for gas fees, abstracting this complexity from your end users. This feature eliminates the need to integrate with third-party paymasters or fee-payers. To set up and configure policies, see Manage Gas Station policies.Bundler
Circle’s Bundler supports Smart Contract Accounts (ERC-4337) by bundling user operations (userOps) for signing. With Circle’s blockchain infrastructure, you can:- Create modular smart contract account wallets.
- Initiate transactions without manually constructing and bundling userOps.
