32-36: Update fromHex factory method to support eth parameterThe fromHex factory method needs to be updated to support the new eth parameter to maintain consistency with the constructor.
Suggested fix:
- public static fromHex(key: string): RawKey { + public static fromHex(key: string, eth = false): RawKey { const hex = key.startsWith('0x') ? key.slice(2) : key if (hex.length !== 64) throw new Error('Invalid private key length') - return new RawKey(Buffer.from(hex, 'hex')) + return new RawKey(Buffer.from(hex, 'hex'), eth) }
Line range hint
8-11: Update class documentation to reflect Ethereum supportThe class documentation should be updated to mention the new Ethereum public key support.
Suggested update:
/** * An implementation of the Key interfaces that uses a raw private key. + * Supports both standard and Ethereum public key formats. */src/key/MnemonicKey.ts (3)
28-31: Enhance the JSDoc comment for theethproperty.The current comment could be more descriptive about the purpose and implications of using an Ethereum public key.
Consider updating the comment to:
/** - * Whether to use eth pubkey + * Whether to use Ethereum public key format instead of the default format. + * When true, the key will be compatible with Ethereum-based operations. */
75-78: Consider adding parameter validation.The
ethparameter is passed directly to the superclass without any type checking or validation.Consider adding explicit validation:
const { account, index, coinType, eth } = { ...DEFAULT_OPTIONS, ...options, } + if (eth !== undefined && typeof eth !== 'boolean') { + throw new TypeError('eth option must be a boolean') + }
Line range hint
44-73: Update constructor documentation with eth option examples.The JSDoc comment for the constructor should be updated to include examples of using the new
ethoption.Consider adding an example:
* ### Generating a random mnemonic * * ```ts * const mk2 = new MnemonicKey(); * console.log(mk2.mnemonic); * ``` * + * ### Using Ethereum public key format + * + * ```ts + * const mk3 = new MnemonicKey({ eth: true }); + * // The key will use Ethereum public key format + * ``` * * @param options

4-4: LGTM: Clean import organization
The import statement is well-organized, grouping related public key types together.
16-16: LGTM: Backward-compatible parameter addition
The optional eth parameter with default false maintains backward compatibility.
src/key/MnemonicKey.ts (2)
38-38: LGTM!
The default value of false maintains backward compatibility with existing implementations.
93-93: Verify the impact of eth parameter in RawKey.
The eth parameter is passed to the RawKey constructor, which according to the AI summary determines the type of public key created.
Let's verify the RawKey implementation:
✅ Verification successful
Based on the shell script results, I can now generate the final response:
The eth parameter in RawKey is correctly implemented and impacts the public key type
The verification confirms that the eth parameter in RawKey's constructor determines whether an EthPublicKey or SimplePublicKey is created. When eth is true, it initializes with EthPublicKey, which:
- Uses a different type identifier ('initia/PubKeyEthSecp256k1')
- Has specific serialization/deserialization logic for Ethereum-compatible keys
- Implements custom address derivation for Ethereum compatibility
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify the RawKey implementation and its handling of the eth parameter
# Check RawKey constructor implementation
ast-grep --pattern 'class RawKey {
constructor($_) {
$$$
}
}'
# Check for EthPublicKey usage
rg "EthPublicKey" -A 5
