Design Overview

Note： Take Solana and Moonriver as examples

From SOL(SPL Standard) to MOVR(ERC20 Standard)

Demo Description

AmaraLink now connects the Moonbase Alpha with the Polygon testnet Mumbai-Testnet, and it will take a few days to apply it to Moonriver Mainnet and Polygon Mainnet.

Preparations before testing:

You will need gas and test coins before testing. For example, if you want your assets cross from Moonbase Alpha to Mumbai-Testnet, test-assets on Moonbase Alpha network and gas DEV are required; conversely, if it’s from Mumbai-Testnet to Moonbase Alpha, then test-assets on Mumbai-Testnet and gas MATIC are required.
