Preparation​

September 2024 Update

Skip now requires a Noble blockchain address. This is due to the fact that transfers go through the centralized CIRCLE bridge, which mints tokens on the Noble blockchain, followed by IBC transfers to the HAQQ Network. This address serves as a backup in case the IBC transfer does not reach the target network.

  1. Install Keplr and add both the Noble and HAQQ networks.
  2. Obtain a wallet address in Bech32 format on the HAQQ network.
  3. Obtain a wallet address on the Noble network.
Obtaining a Bech32 Address in HAQQ Wallet

In the HAQQ Wallet, you can retrieve your wallet address in both EVM and Bech32 formats (the latter is used in Cosmos networks). To do this, click the three dots next to your wallet address and select "Copy Bech32 Address."

Obtaining a Bech32 Address on HAQQ via EVM Address

If you have the recipient's address in EVM format on the HAQQ Network, you can convert it to a Bech32 address using the web app for vesting. Visit this URL: https://vesting.haqq.network/account/0xYOUR_EVM_ADDRESS (e.g., https://vesting.haqq.network/account/0x887fa9cd8427ef96afb5376a60ceb8904514bbe9) and copy the address starting with "haqq1...."
