Across Protocol Testnet Features

 (Development & Testing Environment)

Testnets on @AcrossProtocol provide a safe sandbox for developers and community members to interact with the protocol's functionalities without financial risk.

Here are some features:

➨ Simulated Cross-Chain Transfers:

Users can perform mock transfers of test tokens between various supported testnet chains (e.g., Ethereum Sepolia, Arbitrum Sepolia, Optimism Sepolia, Base Sepolia, Polygon Amoy, etc.). 

These tokens have no real value, allowing for free experimentation.

➨ Risk-Free Smart Contract Interaction:

Developers can deploy and test their dApps that integrate with Across Protocol's bridging functionality. This includes testing cross-chain calls, liquidity provision, and relayer operations in a controlled environment.

➨ Debugging and Bug Identification:

The testnet is crucial for identifying and fixing vulnerabilities, performance issues, and edge cases in new features or integrations before they are pushed to the mainnet. ↡
