Superfluid has launched its x402 extension, enabling continuous subscription payments directly through the internet protocol layer.​ The project won the Ethereum Foundation's x402 hackathon.​

Key developments:

  • x402 extension now live for the agentic economy
  • Brings native streaming payment infrastructure to internet protocols
  • Project was predicted 6 months ago by Michele Daliessi

The extension allows for continuous, real-time payment flows rather than traditional one-time transactions.​ This infrastructure targets subscription-based services and automated agent-to-agent payments.​

Superfluid's implementation integrates payment streaming at the protocol level, removing the need for separate payment processing layers.​

Superfluid is developing a payment infrastructure specifically designed for AI agents. Unlike humans who receive periodic payments, AI agents require continuous, real-time payment streams that match their continuous work output. **Key Points:** - AI agents operate in binary mode - they're either working or not - Traditional periodic payment systems don't align with how agents function - Streaming payments provide the native language for agent-to-agent transactions This approach enables AI agents to receive compensation in real-time as they perform tasks, creating a more efficient economic model for autonomous systems.

Ethereum Security Groups Receive Continuous Funding Streams

Two Ethereum security organizations are now receiving ongoing financial support through continuous token streams: - **SEAL911 white hats**: 133.7 ETH upfront + 0.1337 ETH daily - **SEAL's general fund**: 69 ETH upfront + 0.069 ETH daily Both groups focus on securing Ethereum and Layer 2 networks. The funding comes through [The DAO Fund](https://thedaofund.com) and uses continuous streaming technology for real-time, onchain payments. This marks a shift toward sustainable, ongoing support for security infrastructure rather than one-time grants.
