albert-fu edited this page Jul 26, 2018 · 9 revisions

Notes:

  • With 2.0 release, Wanwallet now supports cross-chain transactions with Ethereum

  • Previous versions of Wanwallet still work as usual after release of Wanwallet 2.0, but new features like cross-chain transactions require Wanwallet 2.0 or later.

  • For users of previous versions, we strongly recommend backing up keystore files in a safe location before upgrading to Wanwallet 2.0 to prevent any kind of data loss, though the upgrading process will not alter existing keystore files in any way.

  • This instruction guide is for Wanwallet 2.0 GUI in which users can send ETH to Wanchain and withdraw ETH from Wanchain to Ethereum.

  • Users can choose between ETH/WAN main network and test network.

  • This version combines ETH light wallet and WAN full node wallet.

Terminology

  • WETH: Wanchain Ethereum Crosschain Token, ETH symbol on Wanchain.

  • HTLC: Hashed Timelock Contracts.
