The standard Elastos Web Wallet and official Elastos Wallet are the most popular among holders of ELA — the former for its simplicity and ease of use and the latter for its DPoS support. Elephant Wallet, the Elastos-approved third-party wallet, brings forth a powerful suite of tools that not only supports ELA, but ties together a robust system of Dapps and their native tokens. Elephant Wallet provides an API layer that is accessible to all DApps. This way, DApps on Elastos do not have to create their own wallets; they can simply integrate Elephant Wallet's API into their own DApps in order to employ its functionality. Elephant Wallet provides support for Dapps through two major avenues of infrastructural integration: Digital Currency Storage & Payment Support Elephant Wallet supports third-party DApps launching on Elastos by providing a storage solution for the DApps' native tokens. In addition, Elephant Wallet facilitates payment and transaction support and offers a "Payment Request" feature, which allows users to request tokens from other wallet holders. DID Sidechain Support Elephant Wallet allows third-party DApps to access Elastos' DID Sidechain to verify user and device identity. DID support is a critical element of transaction authentication processes across the Elastos ecosystem, as it provides a decentralized identification solution that protects user privacy without sacrificing security. Elephant Wallet presents the Elastos ecosystem with a powerful tool to support not only ELA, but also a wide range of DApps and their native tokens. With Elephants Wallet's broad base of features, developers can be confident that their DApps will be secure when they launch their own sidechains in the Elastos ecosystem. In order to build out a strong and diverse ecosystem, Elastos provides the tools and environment to support a wealth of inspiring ideas and brilliant projects; Elephant Wallet is yet another promising pillar in our digital infrastructure.
