Testnet USDC / USDT faucets
Faucet links for testnet USDC / USDT on every chain StableOps supports — use these when working in the playground or sandbox.
The StableOps playground and sandbox only accept testnet assets. Use the links below to claim test USDC / USDT for each supported chain, and keep some native token (e.g. Base Sepolia ETH) around for gas.
Never send mainnet funds through the playground. Every link below points to a testnet faucet — keep testnet and mainnet addresses strictly separated.
Base Sepolia (playground default / fallback)
Pick Base Sepolia · USDC for the easiest end-to-end create → wallet pay → confirmed → finalized run. If the server has scanners configured for additional testnets, the dropdown will list them automatically — just switch to the chain you need.
