Splits ProtocolMessages exceeding NIP-44's 65,535-byte plaintext ceiling
across multiple gift-wrapped events. Symmetric (both directions),
fire-and-forget, backward-compatible via a new transport-level
\`extensions\` field on \`dapp_ready\` and \`wallet_ready\`. Resolves the
\"Failed to swap: invalid plaintext size\" error on aggregated swap
requests and enables signed-tx responses up to the 1 MB BCH consensus
limit (~2 MB hex).
Keep session persistance by default, such that when reloading a dapp,
the wizardconnect session is kept alive.
Improve signature request interface. Simplify the react API.
User may need some time to open their wallet to approve signature
request and miss it.
If we have a active request, re-send it if we see a
wallet_ready signal, suggesting the wallet was just opened.
Replace placeholder 'bip352' / 'bip47_rpa' with the finalized
extension names from the BCR post and BCH Stealth Protocol spec:
- bip352 → bch_stealth_bip352
- bip47_rpa → rpa_bip47
Add spend_path / scan_path fields to each extension handshake
object, pointing to the hardened gate paths where the wallet
exports xpubs. Dapps derive the non-hardened /0 child locally.
Add rpa_spend / rpa_scan path names alongside stealth_spend /
stealth_scan in all examples. Update known extensions table with
full path information and BCR reference links.

This backward compatible change allows wallets/dapps to add additional
features outside the basic transaction signature support to the
hdwalletv1 protocol.
Canonical encoding for BigInt (<bigint: Xn>) and Uint8Array (hex or
<Uint8Array: 0x...>) used in the relay protocol. Provides both
serialization (sourceOutputToRelay, transactionToHex) and deserialization
(parseExtendedJson, toUint8Array, toBigInt) so dapps and wallets
don't have to implement this independently.
The useWizardConnect hook now saves PathXpub[] from wallet_ready into
the localStorage session. On auto-reconnect, restoreSessionPaths() is
called so getPubkey() works immediately without waiting for the wallet.
Corrupt cached paths are cleared with a warning.
Allows dapps to cache the raw PathXpub[] from wallet_ready and restore
them on subsequent page loads. restoreSessionPaths decodes the xpub strings
and populates pubkeyState so getPubkey() works without waiting for the
wallet to reconnect. Throws on invalid xpub data.
This solves an issue where wallet has to scan address ranges for each
derivation path and match it to locking script to figure out what
private key to use for signature.
This is a waste of effort and unnecessary complex for wallet
implementations since the dapp side already knows what inputs its using.
