const Account = {
    properties: {
        balance: {
            type: 'string',
            description: 'balance in unit WEI, presented with hex string',
            example: '0x47ff1f90327aa0f8e',
        },
        energy: {
            type: 'string',
            description: 'energy in uint WEI, presented with hex string',
            example: '0xcf624158d591398',
        },
        hasCode: {
            type: 'boolean',
            description: 'whether the account has code',
            example: false,
        },
    },
} as const;
type Dog = FromSchema<typeof Account>;

// Now: type Dog = unknown
// Expected: type Dog = { balance, ... }

You forgot type: "object" before properties

@NikitaIT sorry I didn't respond earlier. I'm not so sure to want to resolve this issue.

From the spec (and the comment in your linked stack overflow page), type Dog should be a union: { balance, ... } | string | null | boolean | number | unknown[]. Which is not much better than unknown, and would increase type computations and reduce performances.
