Multi-chain, L2 Asset, and New Testnet Support
Zero Hash recently expanded the number of assets available in Certification/Sandbox (“CERT”) and Production (“PROD”) environments available to clients. This launch brings the number of supported production assets to over 60. An asset is defined as a symbol that can be submitted for activities such as trading, rewards, settlement, round ups, staking.
As part of this launch, we are introducing a “dot notation” system for representing tokens that are supported on different multiple blockchains. Newer assets will follow the format [Token].[L1/L2 Chain]. For tokens currently supported that now have multi-chain support, the existing symbol will continue to work without the blockchain symbol (e.g. “.ETH”) appended. For example, USDC was previously only supported on the Ethereum blockchain. The existing symbol (USDC) will continue to work as-is without the “.ETH” appended. Responses will be in the new format (USDC.ETH). In order to call a non-ETH token such as USDC on Algorand, the symbol USDC.ALGO is now required.
