- `conn.cleanup()` calls `client.disconnect()` which closes the WebSocket
transport.
- In the old code, cleanup ran synchronously right after `conn.client.relay(disconnectMsg)`, so the transport was torn down before the async relay message could be transmitted. The error was silently swallowed by `.catch(() => {})` — the disconnect message was never actually sent to the dapp.
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).
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.
This backward compatible change allows wallets/dapps to add additional
features outside the basic transaction signature support to the
hdwalletv1 protocol.
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.
