Ledger - Hardware Wallet
With the release of 3.52.0-mainnet Creditcoin now officially supports Ledger devices. This guide provides step-by-step instructions for setting up your Ledger and using it across multiple wallets. Please note that the prerequisites are common across all supported wallets, so it is recommended to review them first before proceeding to the wallet specific setup.
Please note that this is in addition to Ledger support for EVM based wallets (Metamask, Talisman, Subwallet). Specifically with this release, we are extending support to the Substrate ecosystem on the following wallets :
