RailBridge AIThe Interoperability Layer for Agentic Commerce
Enable cross-chain USDC micropayments so users and agents can pay on their preferred chain, while services receive USDC seamlessly where they prefer.
The Multi‑Chain Payment Problem
Payments are siloed within single chains. Even with x402 enabling agentic micropayments, there is no seamless way to pay on one chain and settle on another.
Liquidity Fragmentation
Each chain has its own tokens and liquidity, forcing users to stay within one ecosystem.
Manual Workarounds
Developers build custom bridges to move value across chains — costly, risky.
Fragmented Merchant Settlement
Merchants get paid across many chains and tokens, making treasury management and accounting significantly more complex.
RailBridge Keeps Settlement Simple
A routing layer on top of x402 that handles cross‑chain settlement
Complete x402 payment on source chain
A user or agent initiates a typical x402 flow on their preferred source chain.
RailBridge AI routes & bridges
The RailBridge facilitator selects a cross‑chain path and handles bridging.
Merchant receives on destination chain
USDC lands on the merchant’s preferred chain with on‑chain receipts for audit.

A sender (user or agent) attaches a payment via x402 on the source chain as a typical x402 flow. The RailBridge router then performs a cross‑chain route, and the merchant receives on its preferred chain with receipts emitted for audit.
