For third-party RPC providers, see RPC Providers. For a typed client that wires these endpoints in for you, see the Stable SDK.
Rate limits
The public RPC endpoints (https://rpc.stable.xyz and https://rpc.testnet.stable.xyz) are rate-limited to 1,000 requests per 10 seconds per IP. Requests over the limit return HTTP 429.
For higher throughput, use a third-party RPC provider.
USDT0 uses 18 decimals as the native gas token (returned by
address(x).balance) and 6 decimals as an ERC-20 token (returned by USDT0.balanceOf(x)). Both interfaces operate on the same underlying balance. Libraries like viem and ethers.js report 18 decimals because they read the native gas token. For details on how the precision gap is reconciled, see USDT0 Behavior on Stable.Add Stable to your wallet
