The problem is figuring out from a Nostr pubkey how to send in a way the user can actually spend. The key MUST be secp256k1 for this to work, which fortunately is a lot of them.

Ohh interesting..
there were non-secp256k1 keys? 😂
Claude says these ones should work:
- Bitcoin
- Ethereum
- Litecoin, Bitcoin Cash, Dogecoin, Zcash
- Tron
- EOS
- Cosmos
- Binance Chain
- Stacks
These ones specifically will NOT work:
- Solana, Cardano, Polkadot, Algorand, Stellar, XRP Ledger, Aptos, Sui - these use ed25519 (Edwards curve)
- Monero - uses ed25519 variant
- Zcash shielded transactions - use Jubjub / BLS12-381
