Payment Channel 402

TOLK smart contract for TON Payment Channels + complete SDK for off-chain micropayments over HTTP 402 + tools for AI agents to use it (MCP, CLI)

A channel between A and B enables machine-to-machine unlimited signed payments in ~50 ms (instant) with no gas fees. Ideal for high-frequency use.

What’s interesting about combining HTTP 402 with Payment Chanels for high-frequency payments is that there’s no longer a need for two-step payment at each request:
x402 payment required → client pays

Once the channel is established between the parties, the client signs each payments directly with the request.

This is significantly reducing the number of requests and accelerating the payment process in the long term.

Note: x402 remains more practical for one-time payments.
