Before you choose

Requirements & limits

The repository is public and licensed under Apache-2.0. The documentation describes use through a standard web browser and Internet Identity, but does not provide verified pricing or a complete account-requirement summary.

  • Supported assets and networks include ICP, ICRC-1, ETH and ERC-20 in the wallet documentation, while Bitcoin and Solana are listed in repository metadata.
  • Internet Identity is used for cross-device access and authentication.
  • WalletConnect enables interoperability with compatible web3 services.
  • The wallet uses Internet Computer network custody and threshold ECDSA rather than a single entity controlling the key.
  • The documentation says Ethereum currently relies on centralized frontend endpoints such as Infura or Alchemy.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
