Oven: Gas-Free BCP and DEFI++

It’s time to formally announce Oven, a new feature from PieDAO providing gas-free pie minting.

What is Oven?

Oven is all about accessibility.

We believe everyone should be able to use our pies to gain automatically rebalancing cryptocurrency exposure.

In our view it’s pointless to provide permissionless pies if a high gas price shuts out many people around the world.

With Oven users can avoid this expense entirely, opening the door for anyone, anywhere, no matter their budget.

How does it work?

The PieDAO Oven allows users to pool their ETH in our smart contract, minting pies together instead of individually. Our treasury currently covers the entire gas cost, making our products much more accessible.

Users deposit their ETH and as soon as the threshold is reached the Oven automatically mints everyone’s pies.

All you need to do is withdraw your freshly baked pie to your wallet.

Oven checks if there’s enough ETH in the contract every fifteen minutes, automatically triggering minting if there’s over 10 ETH ready.

It’s not completely gas-free as you do have to send the initial transaction and then withdraw, but by our estimation Oven saves users up to 97.5% of the cost.

A baking transaction can need 73 transactions and cost as much as 4m GAS. This can be hugely expensive when GAS prices are high. Thankfully with Oven users just need a deposit and withdrawal, costing around 100k GAS.

Currently Oven can be used to mint DEFI++ (our diversified DEFI index) and BCP (Balanced Crypto Pie, containing equal parts BTC, ETH and DEFI++).

More pies will likely be available through Oven in the future.

Wait for other users to deposit and the Oven to fill up.

The pies will be baked after 10 ETH is added, and the contract checks to see if the Oven is ready every fifteen minutes.

As soon as Oven notices the threshold of at least 10 ETH has been reached your pie will be automatically minted and available to withdraw.

It really is that simple, so happy baking!
