Chain-Key (CK) tokens are created using ICP’s cryptographic protocols, enabling secure cross-chain use without intermediaries. Each ck token is backed 1:1 by its original asset, held entirely onchain by a smart contract.
The goal of ck tokens is to bring assets from other blockchains into the Internet Computer, converting them into ICRC tokens, the native token standard on ICP. This gives you fast finality, no gas fees, and seamless compatibility across dApps.
You can currently mint ckBTC and selected ERC-20 tokens directly in Plug.
Here’s how:
Open Plug and go to the DeFi Hub (second tab at the bottom).
Tap Mint CK Tokens.
Choose the token you want from the supported list.
Enter the amount and tap Deposit.
Confirm the transaction and wait for it to process.
For ERC-20 tokens, your balance will update automatically.
For BTC, come back after about 20 minutes and tap Update ckBTC Balance.
Once complete, your ck token will appear in your wallet.
