1. Bitcoin Signature and Koinvote Compatibility
The discussion has shown that Sparrow Wallet is an excellent tool for signing Bitcoin Core messages, which is essential for participating in Koinvote. Unlike Phoenix or Muun, Sparrow supports the “Sign/Verify Message” function and produces signatures compatible with Bitcoin Core. However, Sparrow remains an on-chain wallet and does not support the Lightning Network, which limits its use to traditional transactions.

2. On-Chain Fees and Lightning Network Alternatives
A recurring problem is the high cost of on-chain transactions (Electrum, Sparrow, Blink SV), with fixed fees that make small amounts unprofitable. Lightning wallets like Phoenix or Muun allow users to bypass these fees through automated Lightning Network channels and integrated swaps. However, they cannot sign Bitcoin Core messages, which necessitates combining two tools: an on-chain wallet for signing and an Lightning Network wallet for fast payments.

3. Practical Solutions and Combined Workflow
The most efficient solution is to use Sparrow or Electrum for Koinvote signing, then transfer funds to an LN wallet (Phoenix, Muun) for low-cost payments and receipts. Swap services (Boltz, FixedFloat, SideShift) can also help with the transition from on-chain to LN. In summary, Sparrow offers reliable signatures, Phoenix/Muun provides cost-effective LN payments, and Blink SV remains limited by its fixed fees for small transactions.

Sign/verify on Sparrow is actually what Koinvote needs, but the picture itself is a Phoenix ad, that mismatch looks staged no.

Sign verify under dev is the ususal story only, Koinvote needs that Bitcoin Core signature itself and Phoenix still can't do it no.
