Discord: Cask Protocol

Project Description

Recurring revenue is an essential income stream for most online businesses, but there is currently no safe way to authorize a recurring payment in web3 using a non-custodial wallet. The lack of infrastructure to support recurring payments in web3 has limited merchant adoption. The Cask Protocol aims to solve this problem by facilitating recurring payments between consumers and merchants in a safe, secure way that also generates yield for all parties. Merchants can quickly and easily add a “Subscribe with Crypto” widget on their checkout page and accept payment in crypto.

Current status

  • Subscription protocol is 98% complete and under heavy testing.
  • Initial protocol contracts have been successfully deployed on Mumbai and tested interaction with Chainlink keepers.
  • Subscriptions as NFTs have been created on the Mumbai testnet

Amount requested
10,000 USD


Milestone 1 ($5,000) Show a complete subscription lifecycle processed on chain, all the way from initial subscription creation, multiple renewals, and cancel. The upkeep of the subscription lifecycle will be managed via a Chainlink keeper interface for eventual usage of chainlink keepers on live polygon/mumbai networks.

Milestone 2 ($5,000) Be able to utilize the Cask dashboard dapp to connect the users wallet, allow them to select from a variety of stablecoins, and then deposit them into the Cask Protocol vault contract.
