1. Background

As Cosmochain onboards Klaytn Mainnet, COSM token — which gains utility within the ecosystem — also needs to be swapped to KCT (Klaytn Compatible Token) which has the same technical standards as the Klaytn mainnet.

2. Glossary

  • ERC20: A common technical standard used for tokens based on Ethereum
  • KCT (Klaytn Compatible Token): Token that is compatible with Klaytn mainnet
  • COSM (CosmoCoin): Crypto-currency used within Cosmochain ecosystem

3. Swap Details

  • Swap currently ERC20 COSM to KCT COSM
  • Swap ratio will be 1:1
  • Token name (CosmoCoin), ticker (COSM), and logo do not change

4. Swap Timeline

  • Primary swap : UPbit, Coinone (July 10th, KST)
  • Secondary swap : Other selected exchanges, and wallets (Planned for late July)

5. Swap Method

1) If your COSM is within UPbit or Coinone exchange

2) If your COSM is in secondary exchanges, wallets, Samsung Blockchain Wallet

  • Please transfer your COSM to a primary swap exchange.
  • Otherwise, you can wait for the secondary swap.
  • If the exchange or wallet you keep your COSM hasn’t been selected as a secondary swap exchange, please transfer your COSM to supported exchange or wallet.

<Note 1>
Once swap to KCT is complete for a specific exchange or wallet, ERC20 COSM cannot be deposited to or withdrawn from that exchange or wallet.

<Note 2>
ERC20 and KCT addresses have very similar format. If you insert wrong address during deposit or withdrawal, COSM will be lost. Fee and time will be incurred in order to restore COSM, which may not be restorable in certain cases. When you make deposit or withdrawal, please check your address again before making a deposit or withdrawal.
