Features

1. Flowglad Billing (Zero-Webhook Polling)

// Create 69 snipes/month subscription
POST /subscribe
{
  "user_id": "alice",
  "snipes_per_month": 69,
  "payment_method": "stripe"
}
→ { "checkout_url": "https://checkout.flowglad.io/..." }

// Polling for payment confirmation
async poll_payment_status(sub_id) → "completed" | "pending"

2. Aptos Move Contract Service

GET /contracts/snipe_core
→ { 
  "name": "snipe_core",
  "address": "0x1::snipe_core",
  "functions": [
    {"name": "create", "params": ["creator", "target", "duration"]},
    {"name": "commit", "params": ["signer", "snipe_id", "hash"]},
    {"name": "reveal", "params": ["signer", "snipe_id", "amount"]},
    {"name": "resolve", "params": ["signer", "snipe_id", "actual"]}
  ]
}

// Call Move entry function
POST /call
{
  "module": "snipe_core",
  "function": "create",
  "args": ["my-target", "86400"]
}
→ { "tx_id": "0xabc123..." }

3. Color Bandwidth Market

// Determine winner at interaction time by bandwidth comparison
POST /snipe
{
  "user_id": "alice",
  "target_id": "bob",
  "color_bandwidth": {
    "red": 0.8,
    "green": 0.7,
    "blue": 0.6,
    "extra_spectral": 0.5  // Optional: UV/IR/polarization
  }
}
→ {
  "winner": "alice",      // Higher total bandwidth
  "loser": "bob",
  "bandwidth_diff": 0.42,
  "snipe_used": true      // Decremented from quota
}

Building

Native (Linux/macOS)

cd flowglad-rs-aptos-webvm
cargo build --release
cargo run --release
# Listens on http://0.0.0.0:3000

WebVM (cheerpx/sel4)

# Compile to wasm32-unknown-unknown
cargo build --target wasm32-unknown-unknown --features webvm

# Package for cheerpx
cd cheerpx
./build-webvm.sh ../target/wasm32-unknown-unknown/release/flowglad_aptos_webvm.wasm

# Boot sel4 kernel + webvm runtime
./boot.sh

sel4 Kernel Integration

# Build with sel4 kernel support
cargo build --features sel4-kernel

# Link with sel4 runtime
ld -T sel4_linker.ld \
   flowglad_aptos_webvm.o \
   /path/to/sel4/libsel4.a \
   -o flowglad_aptos.elf

API Examples

Subscribe to Vibesniping (69 snipes/month)

curl -X POST http://localhost:3000/subscribe \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": "alice",
    "snipes_per_month": 69,
    "payment_method": "stripe"
  }'

Execute Snipe

curl -X POST http://localhost:3000/snipe \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": "alice",
    "target_id": "bob",
    "color_bandwidth": {
      "red": 0.9,
      "green": 0.8,
      "blue": 0.7,
      "extra_spectral": 0.6
    }
  }'

Check Subscription Status

curl http://localhost:3000/subscription/alice

Fetch Move Contract

curl http://localhost:3000/contracts/snipe_core

Testing

cargo test
cargo test -- --nocapture  # With println output
cargo test flowglad        # Filter tests

Next steps:

1. Implement real Aptos RPC calls (requires aptos-sdk setup)
2. Integrate Flowglad polling endpoint (requires API key)
3. Connect DuckDB ledger for market history
4. Test sel4 kernel integration with cheerpx
5. Deploy to Aptos mainnet via validator network
