Integrate RelAI facilitator for x402 payment processing
RelAI is a hosted facilitator service that simplifies x402 payment processing on SKALE Network. Instead of running your own facilitator infrastructure, you can use RelAI’s SDK to handle payment verification and settlement across multiple tokens.
The RelAI facilitator has enabled BITE transactions for both SKALE Base and SKALE Base Sepolia.What does this mean?
When a merchant settles any x402 transaction through RelAI facilitator it gets automatically encrypted through BITE and only decrypted at the consensus level
For more inforamtion around BITE please check here.
