DevUpdate: DappV2 | SpartanContractsV2


Well, it’s been an interesting week in the Binance Ecosystem. BNB pumping convincingly towards cementing itself as a serious smart contract pressure release valve for Ethereum whose gas prices continue to make the network unusable for most small to medium-sized ERC20 token-holders. Binance Smart Chain provides a viable ecosystem for users to take advantage of and remove some pressure from Ethereum whist 2.0 is being worked out. The success of the future crypto world will rely on multiple chains working together cleanly and harmoniously; I think it’s clear now BSC will be apart of that world!

Sparta-land has been full of committed community contributors building out the DAppV2 and heavy testing within testnet this week. DAppV2 appears to have all phase1 features fully functional, just a matter of cleaning things up UI/UX-wise to have DAppV2 ready whilst testing continues towards being ready for mainnet and migration.
