Advanced helpers

@seams/sdk/advanced exposes low-level tools for integrations that already own their lifecycle and trust boundaries.

import {
  nearAccountRefFromAccountId,
  thresholdEcdsaChainTargetFromConfig,
  walletSessionRefFromSession,
} from '@seams/sdk/advanced';

Identity builders

Use the exported builders to cross from validated application data into exact SDK subjects:

• toWalletId;
• walletSessionRefFromSession;
• nearAccountRefFromAccountId;
• thresholdEcdsaChainTargetFromConfig;
• walletIdFromWalletProfile.

These builders preserve the relationship between wallet, session, account, and chain. Construct the reference once, then pass it through the operation that requires it.

Other exports

The entrypoint also includes minimal NEAR and EVM RPC clients, transaction encoding, base64url and hashing helpers, WebAuthn RP ID parsing, intent IDs, threshold-session limits, and Tempo fee-token helpers.

These primitives expose more protocol detail and fewer product defaults. The main SDK remains the preferred surface for registration, auth, signing, recovery, and device flows.
