Chain-Key Token Canister IDs

Canister IDs for all chain-key tokens. For deposit and withdrawal flows, see Chain-key tokens.

Mainnet chain-key tokens: live overview including market data
Testnet chain-key tokens: testnet tokens deployed on ICP mainnet

Always query icrc1_fee and icrc1_decimals at runtime. Fees and decimal precision are set per ledger and can change.

ckBTC

Mainnet

Canister	ID
Ledger	`mxzaz-hqaaa-aaaar-qaada-cai`
Minter	`mqygn-kiaaa-aaaar-qaadq-cai`
Index	`n5wcd-faaaa-aaaar-qaaea-cai`
Checker	`oltsj-fqaaa-aaaar-qal5q-cai`

The checker canister monitors KYT (know your transaction) compliance and is called internally by the minter on deposit.

Testnet (Bitcoin Testnet4)

Canister	ID
Ledger	`mc6ru-gyaaa-aaaar-qaaaq-cai`
Minter	`ml52i-qqaaa-aaaar-qaaba-cai`
Index	`mm444-5iaaa-aaaar-qaabq-cai`

Use the Testnet4 canisters for integration testing. The ckBTC minter connects to the Bitcoin testnet4 network, so you need real testnet4 BTC (available from faucets).

ckETH

Mainnet

Canister	ID
Ledger	`ss2fx-dyaaa-aaaar-qacoq-cai`
Minter	`sv3dd-oaaaa-aaaar-qacoa-cai`
Index	`s3zol-vqaaa-aaaar-qacpa-cai`

The ckETH minter also handles all ckERC20 tokens. To get the current Ethereum helper contract address, call get_minter_info on the minter and read deposit_with_subaccount_helper_contract_address. Always verify this before constructing an Ethereum deposit transaction.

Testnet (Ethereum Sepolia)

Canister	ID
Ledger (ckTestETH)	`apia6-jaaaa-aaaar-qabma-cai`
Minter	`jzenf-aiaaa-aaaar-qaa7q-cai`

The Sepolia testnet minter connects to Ethereum Sepolia. Use ckTestETH for integration testing without spending real ETH.

ckERC20

ckERC20 tokens share the ckETH minter. Each token has its own ledger canister. For the authoritative current list, query the minter at runtime; new tokens are added via NNS governance and the table below may lag.

Mainnet

Query the mainnet minter:

icp canister call sv3dd-oaaaa-aaaar-qacoa-cai get_minter_info '()' -n ic
