Hmm, that's confusing.
Mind if we close this PR and move the convo to #201? I see a lot of misconception in this PR, coming straight from some early session experimentations we've made in @solana/mpp.

Sure I'm happy to converge on #201, but can you be a little more specific about what is confusing? I'd love to help contribute!

Summary
This PR adds the Solana session method specification for MPP, enabling
streaming micropayments on Solana via unidirectional payment channels
with Ed25519-signed vouchers.
What this defines
Relationship to existing specs
method="solana"shared with the charge spec (Solana charge intent specification #188)intent="session"following the pattern established by Tempo and Lightning sessionsImplementation
Reference implementation in progress at
https://github.com/alexanderattar/mpp-sdk (fork of solana-foundation/mpp-sdk).
Context
I reviewed PR #188 (Solana charge) with feedback on push-mode tx binding,
blockhash expiry, and Token-2022 handling. This session spec builds on
that charge spec and is designed to be complementary.
Happy to iterate on the spec based on feedback.
