## README

# @hub3js/std

Shared standard layer for `@hub3js` namespace packages. Provides operator
primitives, shared action implementations, builders, hooks, and types that
chain-specific namespace packages (`@hub3js/evm`, `@hub3js/solana`, …) build on
top of.

Exposed via subpaths:

- `@hub3js/std/operators` — `before` / `after` / `and` / `or` recommended hooks
- `@hub3js/std/actions` — shared action implementations (e.g. `disconnect`)
- `@hub3js/std/builders` — pre-wired `ActionBuilder` factories
- `@hub3js/std/hooks` — reusable subscriber builders (e.g. `ChangeAccountSubscriberBuilder`)
- `@hub3js/std/types` — foundational types (`Namespace`, CAIP accounts, common actions, `InstanceMap`)
- `@hub3js/std/utils` — CAIP validation

## Connect errors

End each connect chain with the `standardizeAndThrowError` or-hook from
`@hub3js/std/operators`. It throws a `Hub3Error` typed
`PROVIDER_USER_REJECTED_REQUEST`, `PROVIDER_LOCKED` or `PROVIDER_UNEXPECTED`
(see [`@hub3js/core`](../core/readme.md#errors)); a value without a message
gives an empty message. It never produces `PROVIDER_LOCKED` itself: a wallet
returns that type from an earlier or-hook, and it is passed through untouched.
