better-near-auth

Set up the siwnClient plugin for Better Auth client, configure NEAR wallet connection via NearConnect, use authClient.near actions for sign-in, profile lookup, account management, delegate action building with TransactionBuilder, and relay submission. Load when implementing NEAR wallet sign-in on the client, using authClient.near.* methods, or building delegate actions for gasless relay.

Configure the gasless NEP-366 delegate action relayer in ephemeral or explicit mode, relay signed delegate actions on-chain, enforce contract whitelisting and gas/deposit limits, check relay status and history, and use the contract view endpoint. Load when setting up relayer config, debugging relay failures, or configuring RotatingKeyStore for high-throughput relay.

Set up the SIWN server plugin for Better Auth, configure NEP-413 authentication with recipient and API key, handle nonce generation, signature verification, account linking and unlinking, and NEAR profile lookup. Load when adding NEAR wallet sign-in to a Better Auth server, configuring siwn() plugin options, or debugging NEP-413 verify or nonce issues.

Integrate better-near-auth with TanStack Router (SSR or CSR). Set up auth client as a router context singleton, useAuthClient hook, session query options, inferred types from AuthClient, and ensureConnected before signing. Load when scaffolding a new TanStack Router app with better-near-auth, wiring auth into router context, or debugging wallet state loss after sign-in in SSR/CSR TanStack apps.

Mount and consume the @everything-dev/auth-plugin in an everything-dev or every-plugin project. Register it in bos.config.json, wire the Better Auth client into the UI with siwnClient/passkey/API-key/organization plugins, protect routes with session checks, compose with the auth plugin in-process via createPlugin.withPlugins, and use the auth context (getContext) in your own oRPC middleware. Sub-account creation is supported in bos.config.json for scalar fields (parentHasFullAccess, minDeposit, deploy.fromPublished, init with static args, addRelayerFCAK, relayerFCAK). Load when adding auth to an everything.dev app, configuring SIWN recipients from runtime config, calling auth endpoints from another plugin, or debugging auth context resolution.

Configure sub-account creation with parent ownership, contract deployment, init calls, composable transaction hooks, and lifecycle callbacks with automatic rollback. Load when setting up subAccount config, deploying contracts to new sub-accounts, or handling post-creation side effects.
