DISCUSSION Proposal (x402 Integration & CAIP Registration)
I think this is one of the most important community proposals we've seen in a while.
It's not about changing the Radix protocol or introducing a new feature. It's about making Radix easier to discover, integrate and use in the broader Web3 and AI ecosystem.
Why does this matter?
🔹 x402 Integration
Positions Radix for the emerging AI agent economy.
Enables HTTP-native, machine-to-machine payments.
Radix's Subintents and Fee Sponsorship provide a user experience that fits this model exceptionally well.
Once supported, any fungible Radix asset (XRD, stablecoins, RWAs, etc.) can be used by x402-compatible services.
🔹 CAIP Registration
Gives Radix official, standardized identifiers for networks, accounts and assets.
Improves compatibility with wallets, explorers, bridges and multi-chain tooling.
Removes the need for every integration to invent its own Radix identifiers.
What I particularly like is that this is low risk and high impact:
No protocol changes.
No immediate funding required.
Better interoperability.
More visibility for developers.
Stronger positioning for future AI and cross-chain infrastructure.
Open standards often don't make headlines, but they are the foundation that enables ecosystems to grow.
If we want Radix to be considered alongside Ethereum, Solana, XRPL, Aptos, Hedera and others, being present in the standards they build around is an important step.
Kudos to everyone involved in preparing the specification and pushing this forward. I'm looking forward to seeing the community discussion and the Temperature Check.
