 Launches an interactive CLI where you can select:
-- **Facilitators** - Payment verification/settlement services (Go, TypeScript)
+- **Facilitators** - Payment verification/settlement services (Go, TypeScript, Python)
 - **Servers** - Protected endpoints requiring payment (Express, Gin, Hono, Next.js, FastAPI, Flask, etc.)
 - **Clients** - Payment-capable HTTP clients (axios, fetch, httpx, requests, etc.)
 - **Extensions** - Additional features like Bazaar discovery
-- **Protocols** - EVM, SVM, and/or Aptos networks
+- **Protocols** - EVM, SVM, Aptos, Stellar, and/or TVM networks
 
 Every valid combination of your selections will be tested. For example, selecting 2 facilitators, 3 servers, and 2 clients will generate and run all compatible test scenarios.

+# x402 TVM Mechanism
+
+TON/TVM implementation of the x402 payment protocol using the **Exact** payment scheme with jetton transfers relayed through W5R1 and highload-wallet-v3 wallets.
+
+## Installation
+
+```bash
+uv add x402[tvm]
+```
+
+## Overview
+
+Three components for handling x402 payments on TVM-compatible networks:
+
+- **Client** (`ExactTvmClientScheme`) - Creates signed W5R1 payment payloads
+- **Server** (`ExactTvmServerScheme`) - Builds payment requirements and parses prices
+- **Facilitator** (`ExactTvmFacilitatorScheme`) - Verifies payloads and relays settlements on-chain
+
+`ExactTvmScheme` in `x402.mechanisms.tvm.exact` is an alias for the client scheme (`ExactTvmClientScheme`).
+
+## Quick Start
+
+### Client
+
+```python
+import os
+
+from x402 import x402Client
+from x402.mechanisms.tvm import TVM_TESTNET, WalletV5R1Config, WalletV5R1MnemonicSigner
+from x402.mechanisms.tvm.exact import ExactTvmScheme
+
+config = WalletV5R1Config.from_private_key(
+    TVM_TESTNET,
+    os.environ["TVM_CLIENT_PRIVATE_KEY"],
+)
+config.api_key = os.environ.get("TONCENTER_API_KEY")
+
+signer = WalletV5R1MnemonicSigner(config)
+
+client = x402Client()
+client.register(TVM_TESTNET, ExactTvmScheme(signer=signer))
+
+payload = await client.create_payment_payload(payment_required)
+```
+
+Call `scheme.close()` when you are done with a long-lived `ExactTvmScheme` so its cached Toncenter HTTP clients are released.
+
+### Server
+
+```python
+from x402 import x402ResourceServer
+from x402.mechanisms.tvm.exact import ExactTvmServerScheme
+
+server = x402ResourceServer(facilitator_client)
+server.register("tvm:*", ExactTvmServerScheme())
+```
+
+### Facilitator
+
+```python
+import os
+
+from x402 import x402Facilitator
+from x402.mechanisms.tvm import HighloadV3Config, TVM_TESTNET, FacilitatorHighloadV3Signer
+from x402.mechanisms.tvm.exact import ExactTvmFacilitatorScheme
+
+config = HighloadV3Config.from_private_key(os.environ["TVM_FACILITATOR_PRIVATE_KEY"])
+config.api_key = os.environ.get("TONCENTER_API_KEY")
+
+signer = FacilitatorHighloadV3Signer({TVM_TESTNET: config})
+
+facilitator = x402Facilitator()
+facilitator.register([TVM_TESTNET], ExactTvmFacilitatorScheme(signer))
+```

+
+## Supported Networks
+
+- `tvm:-239` - TON mainnet
+- `tvm:-3` - TON testnet
+- `tvm:*` - Wildcard (all supported TVM chains)
+
+## Asset Support
+
+Supports [TEP-74](https://github.com/ton-blockchain/TEPs/blob/master/text/0074-jettons-standard.md) jetton payments with explicit asset requirements:
+
+- Mainnet USDT (`USDT_MAINNET_MINTER`)
+- Testnet USDT (`USDT_TESTNET_MINTER`)
+- Any TEP-74 jetton when the server is given an explicit asset address
+
+Server-side prices may be supplied as:
+
+- `AssetAmount(...)` or `{"amount": "...", "asset": "..."}` for an explicit jetton
+- `int`, `float`, or strings like `"$0.01"` and `"0.01 USDT"` for built-in USDT conversion
+
+For non-default jettons, provide either:
+
+- the amount in atomic units, or
+- `extra.decimals` so decimal amounts can be normalized correctly
+
+## Technical Details
+
+### Client Wallet Format
+
+The TVM client flow uses Wallet V5R1:
+
+1. Build wallet state init from the configured private key
+2. Read account state and seqno from Toncenter
+3. Derive the payer jetton wallet for the configured asset
+4. Create a signed W5R1 internal message targeting the payer wallet
+5. Wrap the message as a base64 BOC settlement payload
+
+The signer network must match the selected payment requirement network.
+
+### Facilitator Settlement Flow
+
+The facilitator batches relay requests through a highload-wallet-v3 account:
+
+1. Verify the settlement BOC, signature, wallet code hash, wallet id, seqno, timeout, and jetton transfer
+2. Reserve the settlement in `SettlementCache` to reject duplicate settlements
+3. Batch valid relay requests per network
+4. Send the batched external message through the facilitator wallet
+5. Wait for finalized trace confirmation through Toncenter APIs
+
+Call `signer.close()` when you are done with a long-lived facilitator signer so its Toncenter clients and streaming watchers are released.
