Making a key in a object with jsonb unique

type Wallets = {
    wallet_address: string;
    blockchain: string;
};

export const user = pgTable(
    'user',
    {
        id: serial('id').primaryKey(),
        wallets: jsonb('wallets').$type<Wallets[]>(),
);

type Wallets = {
    wallet_address: string;
    blockchain: string;
};

export const user = pgTable(
    'user',
    {
        id: serial('id').primaryKey(),
        wallets: jsonb('wallets').$type<Wallets[]>(),
);

Technically you can't. Your best option is to have an other table with wallet_address as primary key and userId as foreign key (1 user can have many wallets but a given wallet has only one owner).

Then, query api will help to grab everything together: https://orm.drizzle.team/docs/rqb

@Raphaël M (@rphlmr) ⚡ is right, however technically you can build your own sql query that will only allow the insertion of unique wallet objects based on a predefined key.
