{% hint style="warning" %}
Stargate testnet has been redeployed as of 22nd Jan 2024. The old testnet contracts are no longer supported. 

There is currently support for the following testnets: Sepolia (Ethereum Testnet), Fuji (Avalanche Testnet), BNB Chain (Testnet), Arbitrum Sepolia (Testnet), Optimism Sepolia (Testnet) and XCHAIN (IDEX Testnet).
