RelAI now supports USDC, USDT, WBTC, and WETH payments on both SKALE Base and SKALE Base Sepolia, with gas sponsored by the facilitator.
We have expanded RelAI payment support on SKALE to cover four tokens on both supported SKALE Base networks:
- USDC
- USDT
- WBTC
- WETH
- SKALE Base
- SKALE Base Sepolia
What this means for API providers
If your endpoint is configured on SKALE Base or SKALE Base Sepolia, your users can now pay with more than just USDC. That gives better wallet compatibility and makes onboarding easier for users who already hold USDT, WBTC, or WETH on SKALE.

Settlement and UX
All of these payments go through the same RelAI flow:
- User signs a payment authorization
- Facilitator settles on-chain
- RelAI sponsors gas for settlement
Available now in playground and API pricing
The update is already active in the dashboard playground and in API pricing configuration for SKALE Base networks.
If you run your own integration with @relai-fi/x402, update to the latest SDK version to get the same token metadata and signing defaults.
More token choice on SKALE means less friction at checkout and better conversion for paid APIs.
