I need working architecture and code paths, not opinions. +I am building a local AI agent (Timmy) on FastAPI that accepts paid work requests over Lightning Network. The payment architecture: + 1. User submits a request + 2. A small non-refundable Lightning invoice (evaluation fee) must be paid before the agent reads the request + 3. Agent evaluates the request using a cheap local model + 4. If accepted, agent quotes a price and issues a second Lightning invoice + 5. User pays, work is delivered + 6. Optionally, users can prepay a session (batch of N requests) via a single invoice and receive a macaroon with a usage meter +I want to issue a custom Taproot Asset token (“TIMMY”) that represents one unit of the agent’s labor. This token should be transferable over Lightning channels instantly. The token is consumed on use — it is a labor credit, not an investment. +Research the following and provide concrete implementation details: +1. Taproot Asset Minting + ∙ What are the exact steps to mint a custom fungible Taproot Asset on mainnet using tapd + LND? + ∙ What version of LND is required? What flags/tags must be compiled? + ∙ What does the gRPC call look like to mint? Provide the actual protobuf message or CLI command. + ∙ What is the on-chain cost of the minting transaction? + ∙ Can the entire supply be minted in a single transaction? + ∙ How do you verify the asset was minted correctly? +2. Taproot Assets on Lightning Channels + ∙ How do you deposit a Taproot Asset into a Lightning channel? + ∙ Can a Taproot Asset channel coexist alongside a BTC channel in the same UTXO? + ∙ How does routing work — can a TIMMY token payment route over existing BTC Lightning channels via edge nodes, or does it require dedicated Taproot Asset channels end-to-end? + ∙ What happens if no direct Taproot Asset route exists — does the protocol fall back to BTC conversion at edge nodes? + ∙ What is the current state of Taproot Asset channel support in LND (v0.20+)? +3. L402 Payment Gate with Taproot Assets + ∙ Can Aperture (Lightning Labs’ L402 reverse proxy) gate access using Taproot Asset payments, or only BTC sats? + ∙ If Aperture only supports sats, what is the minimum custom code needed to accept Taproot Asset payments as L402 credentials? + ∙ How would a macaroon encode that payment was made in TIMMY tokens vs. sats? + ∙ Is there a way to implement the “session pass” pattern (prepay N requests, get a metered macaroon) using Taproot Assets? +4. FastAPI Integration + ∙ What is the most production-ready Python path to interact with tapd (Taproot Assets daemon)? gRPC stubs? REST? LNbits extension? + ∙ Does LNbits support Taproot Assets as of March 2026? + ∙ Provide a minimal FastAPI endpoint that: creates a Taproot Asset invoice, checks payment status, and issues a macaroon on confirmation. + ∙ How do you query a user’s TIMMY token balance programmatically? +5. Hybrid Architecture: Sats + TIMMY Token + ∙ If Taproot Asset Lightning support is not yet production-ready, what is the cleanest hybrid? Users pay in sats via standard Lightning, but the internal ledger tracks TIMMY credits? + ∙ How do you peg TIMMY credits to sats? Fixed rate set by operator, or floating based on demand? + ∙ When Taproot Asset channels mature, what is the migration path from the hybrid model to native token payments? +6. What Breaks + ∙ What are the known failure modes of Taproot Assets on Lightning as of March 2026? + ∙ What is NOT yet implemented in tapd that this design requires? + ∙ Are there any mainnet Taproot Asset channels in production, or is this still testnet-only for asset channels? + ∙ What is the risk of building on Taproot Assets today given the protocol is still evolving? +Deliverable: A structured implementation guide with exact commands, library versions, gRPC/REST call examples, and a clear flag on anything that is not yet production-ready. Prioritize what works today over what is promised. If something requires waiting, say so and provide the interim workaround \ No newline at end of file
