# Tempo Wallet Integration Status

**Date:** 2026-04-02  
**Status:** Current implementation audit

## Summary

Agentbot already has a wallet dashboard, balance APIs, fee payer route, wallet session routes, and wallet top-up/create surfaces in the repo. This is no longer a blank spec. The remaining work is mostly around hardening, persistence, and true end-to-end wallet UX.

## Implemented

### Dashboard And Wallet APIs

- `web/app/dashboard/wallet/page.tsx`
  - Wallet dashboard exists.
  - Supports local address connect, balance display, and session open/close UI.
- `web/app/api/wallet/route.ts`
  - Reads Tempo balances for known tokens.
- `web/app/api/wallet/transactions/route.ts`
  - Wallet transactions API exists.
- `web/app/api/wallet/address/route.ts`
  - Wallet address route exists.
- `web/app/api/wallet/create/route.ts`
  - Wallet creation route exists.
- `web/app/api/wallet/top-up/route.ts`
  - Wallet top-up route exists.

### Payment Sessions

- `web/app/api/wallet/sessions/route.ts`
  - Create, list, and close MPP sessions.
- `web/app/api/wallet/sessions/voucher/route.ts`
  - Voucher route exists.
- `web/lib/mpp/sessions.ts`
  - Session model, voucher processing, threshold settlement hooks, and close flow are implemented in memory.
- `web/lib/mpp/session-fetch.ts`
  - Session ID handling exists on the client side.

### Fee Sponsorship

- `web/app/api/fee-payer/route.ts`
  - Fee payer handler exists and is auth-gated.
  - Returns `503` when `TEMPO_FEE_PAYER_KEY` is not configured instead of crashing.

## Partially Implemented

### Wallet Connection UX

- Current wallet connect is address-based in `web/app/dashboard/wallet/page.tsx`.
- That is workable for internal/testing flows, but it is not a full passkey Tempo Wallet onboarding experience.

### Session Persistence

- `web/lib/mpp/sessions.ts` stores sessions in memory.
- This is fine for local/dev prototyping and demo flows, but not production-safe.

### Settlement

- Voucher accumulation exists.
- Actual settlement and refund steps are still TODO-backed placeholders in `web/lib/mpp/sessions.ts`.

### Fee Sponsorship

- Route exists, but depends on `TEMPO_FEE_PAYER_KEY`.
- Sponsorship limits, abuse controls, and operator accounting are not fully documented here.

## Missing Or Incomplete

- Durable storage for wallet sessions and vouchers
- Real on-chain settlement and refund logic
- Full Tempo Wallet passkey onboarding in the product flow
- Clear top-up and transaction-history UX tied to authoritative backend data
- Production monitoring around fee payer usage and failed sponsorship attempts

## Current Backlog

### Next

- Move session state out of memory into durable storage.
- Finish on-chain settlement and refund execution for wallet sessions.
- Add a proper Tempo Wallet connect/onboarding path instead of raw address entry.

### Then

- Improve transaction history quality and source of truth.
- Add operator-side limits, observability, and abuse protections for fee sponsorship.

## Notes

- The old phased spec in this file was inaccurate. Wallet, session, and fee payer primitives already exist in code.
- This file should now be treated as a status document for the remaining hardening work.
