- You have ERC-20 token if you hold your tokens in an ETH wallet or exchanges, and the wallet address starts with “0x” like this “0x68cb76dea7d391c5e5bb51ebbcd30001b0d9fe12”
- You have tNKN (also known as testnet) tokens if you mine and hold your token in a NKN testnet wallet, and the wallet address starts with letter “N” like this “NQBPH4TxeD7WFkFienrrWrpVaDdV7bD5KY”
- Which wallet should I use for mainnet NKN token?
- We will offer an official web, desktop, and mobile wallet for NKN mainnet. Stay tuned for more info on nknwallet.io
- Partner wallets will announce their mainnet NKN token support once integration work is completed with NKN.
- Why do I need to swap from ERC-20 to mainnet or vice versa?
- Swap is not required, but may be needed depending on the exchange or service you would like to use.
- If you want to pay for networking services (e.g. nCDN, Pub/Sub) on NKN mainnet, then you need NKN mainnet tokens.
- You received mainnet NKN token either through mining or payment by running micro services such as nCDN, and you would like to trade ERC-20 tokens for other cryptocurrencies or fiat.
- Or in the future, your preferred exchange has migrated from ERC-20 to NKN mainnet tokens. In this case, the exchange will handle the swap automatically, thus no action is required from you.
