# ⏰💰🤠 Token Subscriptions 🤠💰⏰

[![tokensubscriptionscreencast](https://user-images.githubusercontent.com/2653167/45360744-be265700-b58d-11e8-9ffc-10e1e57dafb0.jpg)](https://youtu.be/I16a_XKAVoY)

[https://tokensubscription.com](https://tokensubscription.com) allows publishers (service providers) to deploy a smart contract on Ethereum with parameters for a subscription including destination address, token address, token amount, and period of recurrence. The publisher then supplies a link to the subscriber that is presented with the terms of the subscription to sign an off-chain meta transaction that is replayed on the defined period. The subscriber controls the flow of the tokens (starting, stopping, pausing, etc) using the ERC20 standard approve() function.

Usually a nonce is used for replay protection, but the heart of the trick with [https://tokensubscription.com](https://tokensubscription.com) is a replay-able nonce that works on a defined schedule. In combination with the ERC20 allowances and meta transactions an extremely simple token subscription service can be created.
