Using the Citizen Wallet at Crypto Wednesday

We lost the keys of @bar @bank @xavier @kevex91 so we ended up redeploying a new ERC20 contract and minting the previous balance for everyone.

Transactions got stuck because of Polygon.

We need our own sidechain / cache / buffer to make sure we don’t block the flow of transactions. We could commit to the chain in a different thread / at different intervals.

@cryptobar received 146 zinnes in 25 transactions, current balance: 278.5 zinnes

DAO.brussels

🔬 Quick follow up on the first experiment of using an on-chain version of the local currency "Zinne.brussels" at the last Crypto Wednesday Bar 🍻🍕

The bar received 29 transactions for a total of 132.50 ZINNE
We sold for €199 of Zinne, including my own €50

How was the experience for you? How would you make it better for next time?

Learnings

It’s a pain to have to manage both a paper version and a digital version. I now understand why some shops refuse to deal with cash
It’s important to offer a discount to incentivize people to pay with the token (or to add a tax if they want to pay with euros, or simply to not allow any other payment method)
It’s great to offer transparency towards the community on how much the bar has collected

Ways to improve

Add a message with the transaction to know what we paid for
Have a live dashboard (on a phone / tablet) to show real time transactions and a play a “DING” whenever a transaction happened
Automate onramp (monerium and/or Stripe)
