🚨 Reminder: A personal
@safe
is the most secure way to store your crypto. It's trusted by Vitalik, Punk6529 and crypto whales to store $40B+.
You can get the same level of security and it only takes a few minutes to set up:
Using a gnosis safe to secure your assets is one of the best ways to keep your funds safe, but CT never talks about it.
It’s not about ease, (although it’s pretty easy to access…) it’s about protection.

NFTs have sparked a new digital economy - spanning across art, games, community, culture and finance.
Despite this, tools for NFTs have been lacking sophistication. Notable challenges include security and poor UX.

On top of that, the poor UX of tools makes us worry unnecessarily. We have to triple-check transactions just to be safe. Fragmented tools also make it hard for people to get started.

This feature uses the CREATE2 method to reserve the address of your vault.
With the reserved address, you can secure assets in it without needing to pay upfront gas fees.
When you make your first tx from the vault, it will then be deployed on-chain in a batched transaction.

To get this set up:

2. Import & select the safe you’d like to delegate from
3. Setup your delegate details in the settings page

Castle takes this one step further by letting you post listings to
@opensea
in bulk, or off-chain to save on gas fees.💸
Our on-chain listing flow batches all approve token + listing txns together so you only need to collect 1 set of signatures.✍️
We’re now ingesting Seaport listings and offers posted on-chain! Any smart contract will be able to post listings and offers directly on-chain that will show up and be fulfillable on OpenSea.
This now opens up many exciting new use cases – like DAOs buying/selling together 🥳

At its core, crypto is about creating an open and permissionless system where you don’t need to trust centralized entities.
