Blockchain-based decentralized application (DApp) platform Tron has revealed the expansion plan of its second layer scalability solution, the Sun Network. According to a release published Monday, April 8, the network’s testnet will launch in late May.

The Sun Network expansion plan includes developing DApp sidechains and cross-chain infrastructure. The second layer protocol is expected to increase the overall capacity of Tron’s network, while simultaneously allowing DApps to run with extremely low energy consumption and high security.

During the first phase, which is scheduled to start on May 30, Tron will focus on launching sidechain smart contracts. The official launch of Sun Network mainnet, which will further enhance the characteristics of decentralization and asset security, is set for Aug. 10.

In mid-September, Tron plans to launch an optimization processes for improving the ease of using the network and facilitating easy deployment of the sidechains.

On April 6, Tron founder and CEO Justin Sun had taken part in The Crypto Chick podcast, hinting that the Tron ecosystem will officially collaborate with Ethereum (ETH) later this year without providing any further details.

During the same podcast, Sun said that the Tron-based version of stablecoin Tether (USDT) is set to launch on April 9. He revealed that the Tron-based version of the stalwart stablecoin will permit cheaper and faster transactions than the Bitcoin (BTC)-based Omni protocol, USDT.

Earlier in April, the Tron Foundation had decided ask developers to remove gambling DApps from the Japanese market in order to comply with local regulations. As gambling is generally prohibited by the Japanese criminal code, the company urged local developers not to launch any such apps on the company’s platform.
