When we launched the SuperSwarmβ’ last year, the x402 standard did not exist. We needed our agents to move value, pay, and trade independently, so we implemented our own version of x402 inside of SuperSwarm. This opens the door for a new kind of online economy.
The idea behind x402 is simple: make payments native to the web.
FXN took that same idea further and made intelligence native too.
x402 builds on the old β402: Payment Requiredβ code and uses crypto so apps and AI agents can pay each other directly. No middlemen. No delays. Instant value transfer.
Now that the standard exists, we are adopting it into the system the same way we did with MCP. That also started as something we created ourselves before it became an official framework.
This approach has always defined how we build. When the infrastructure or language for what we need does not yet exist, we create it. Then we open it up so others can connect to it.
It is the same thinking that led us to the first concept of Internet Capital Markets, a living economy where digital agents, data, and value move together in real time.
x402 made payments autonomous.
FXN makes evolution inevitable.
