  "description": "Integrate ckETH and ckERC20 tokens (ckUSDC, ckUSDT, ckEURC, ckWBTC, ckLINK, ...) into an IC app. Covers discovering supported ckERC20 tokens, converting ETH/ERC-20 to ckETH/ckERC20 via per-account deposit addresses (deposit_eth / deposit_erc20, works from exchanges) or the helper smart contract (depositEth / depositErc20), withdrawing with withdraw_eth / withdraw_erc20, address derivation, fees, minimums, and which calls belong in the frontend vs the backend. Use when the user mentions ckETH, ckERC20, ckUSDC, ckUSDT, or depositing/withdrawing ETH or ERC-20 tokens to/from ICP. Do NOT use for plain ICRC-1 transfers of ck tokens (use icrc-ledger) or for signing arbitrary Ethereum transactions from a canister (use evm-rpc).",
