Extra Releases: Audits and samples

Last Friday marked the end of [Openfort Launch week 1](https://www.openfort.xyz/launch-week), our launch week focused on empowering developers to build better ecosystem wallets and cross-chain experiences.

In the last five days, we shipped five major features and improvements.

Here's a quick recap of what we launched:

[Day 1: Ecosystem customization tool](##Day-1-Ecosystem-customization-tool)
[Day 2: Ecosystem SDK 2.0](##Day-2-Ecosystem-SDK-2.0)
[Day 3: Guest accounts and new samples](##Day-3-Guest-accounts-and-new-samples)
[Day 4: React Native SDK](##Day-4-React-Native-SDK)
[Day 5: Chain abstraction framework](##Day-5-Chain-abstraction-framework)
[Extra: ZkSync contract audit](##Extra-release-ZkSync-audit)

## Day 1: Ecosystem Customization Tool

On Monday, we introduced a new tool designed to make building ecosystem wallets more accessible to everyone. The Ecosystem Customization Tool simplifies the process of creating tailored wallet experiences through an intuitive interface.

Key features include:
- Pre-built theme selection
- Custom color palette configuration

## Day 2: Ecosystem SDK 2.0

Tuesday brought a major upgrade to our SDK, focusing on developer experience and enhanced functionality. Ecosystem SDK 2.0 introduces several groundbreaking improvements:

- Removed API key requirements for simpler integration
- Added ERC5792 standard compatibility
- Implemented encrypted communication via Mobile Wallet Protocol (MWP)
- Streamlined package management

[Read announcement](https://www.openfort.xyz/blog/announcing-ecosystem-wallet-2)

## Day 3: Guest accounts and new samples

On Wednesday, we unveiled Guest Accounts, a feature designed to reduce friction in user onboarding. This powerful addition allows users to:
- Start using apps immediately without login requirements
- Maintain persistent access through local storage
- Seamlessly upgrade to full accounts when ready

[Read announcement](https://www.openfort.xyz/blog/guest-accounts)

## Day 4: React Native SDK

Thursday saw the alpha release of our React Native SDK, bringing Openfort's powerful wallet functionality to mobile development. The release includes:
- Full React Native compatibility with ecosystem SDK and embedded wallet
- Comprehensive Expo support
- Cross-platform authentication
- State synchronization across web and mobile

[Read announcement](https://www.openfort.xyz/blog/react-native-sdk)

## Day 5: Chain Abstraction Framework

We concluded the week with our most ambitious release yet: the Chain Abstraction framework. This revolutionary system enables:
- Cross-chain interactions using time-locked vaults
- Integration with MagicSpend++ and Polymer's Prove API
- Ecosystem-owned liquidity provision
- Trust-minimized execution with onchain proving

[Read announcement](https://www.openfort.xyz/blog/chain-abstraction)

## Extra release: ZkSync audit
A final suprise. We announced the ZkSync smart contract audit as well as the overall improvements in our infrastructure enabling us to speed the acount creation and processing for our clients.

[Read announcement](https://www.openfort.xyz/blog/extra-launch-1)

## Looking Forward

This launch week represents a significant step forward in our mission to make wallet development and cross-chain interactions more accessible and efficient. From simplifying wallet creation to enabling seamless cross-chain operations, each feature was designed with developer experience and user needs in mind.

See you in the next one!

Everything we launched during the first launch week.

Openfort Launch Week 1: Wrap up

Ecosystems serve as parent entities for groups of apps operating across different blockchains. Openfort [ecosystem wallets](https://www.openfort.xyz/docs/guides/ecosystem) enable seamless interoperability between applications, allowing ecosystems to design their ideal, unified wallet experience. The next evolution is to consolidate user liquidity across apps, providing a single, unified balance that is instantly spendable across the ecosystem.

A significant step towards unifying liquidity across the space are cross-chain interactions. By leveraging **time-locked vaults** and **onchain proofs**, our ecosystems can now provide users with a unified balance instantly accessible across all apps within their ecosystem.  

This first implementation builds on:
- [MagicSpend++](https://ethresear.ch/t/magicspend-spend-now-debit-later/19678/9) with **time-locked vaults** to simplify cross-chain operations while ensuring security and speed. 
Vaults can be yield-bearing. Users deposit once to enable chain abstraction and put their money to work. Different yield strategies will come.
- [Polymer's Prove API](https://docs.polymerlabs.org/docs/learn/intro), simplifying contract development by replacing manual cross-chain messaging with a more intuitive and native approach of **on-chain proofs**.

![chain-cmd.jpg](https://strapi-oube.onrender.com/uploads/chain_cmd_a5719f7cb5.jpg)

### Why this matters  
Chain abstraction is an ambitious space with many approaches. Most rely on third parties (fillers/solvers) that will compete to front liquidity on destination chains in exchange for fees. At Openfort, we grant the ecosystem the power to become an LP for its users and only rely on external liquidity when required.

With our setup, ecosystems can deploy tailor-made 4337 chain abstraction infrastructure. They become Liquidity Providers (LPs) for their users, sharing with them the value that would otherwise have been captured by fillers/solvers.

- **Intents**: Allow users to express what they want to do, regardless of the underlying blockchain.  
- **Time-locked vaults**: Assets locked in the vault serve as a guarantee for Payamasters.
- **Onchain proving**: Ecosystem can’t be repaid without cross-chain execution proof —zero trust assumption. The InvoiceManager contract tracks onchain repaid invoices to forbid double repayment.

This means your users can securely:  
- Buy assets on one chain using liquidity from another  
- Deposit any ERC20s on any chain to increase their chain abstracted balance
- Interact with apps across blockchains without friction  

### How it works  

![mermaid.png](https://strapi-oube.onrender.com/uploads/Screenshot_2024_12_30_at_14_47_19_7704205675.png)

At the heart of our system are:  
- **Time-locked vaults**: Securely lock user funds, ensuring they’re only used as intended. It can be yield-bearing. 
- **Chain abstraction paymasters**: 4337 compatible paymasters which handle gas and destination chain transaction costs. Ecosystems own them. They’re approving the required ERC20s after validating the Openfort backend signature.

In practice, an ecosystem can deploy its onchain infrastructure, acting as a liquidity provider for its users. Funds locked on the origin chain are released only after transaction proof is obtained from the destination chain.

This design ensures:  
- **Frictionless user experience**: Transactions feel as fast as same-chain operations.  
- **Non-custodial security**: Openfort Backend authorizes transactions but cannot spend funds. 
- **Trust-minimized execution**: Users can withdraw all their chain abstracted balance after a configurable lock period. Ecosystems can rage-quit (i.e., instantly withdraw all liquidity from their paymasters). Neither Openfort nor the Ecosystem can get refunded without the userOp execution proof verified on the source chain.   

This approach makes interop simple, fast, and secure. Ecosystems can share value with users instead of solvers while ensuring liquidity is always available where needed.  

### What’s next?  
For ecosystem: automatic liquidity rebalancing between chains with Openfort custom alerts when a Paymaster balance is lower than a programmable threshold.

For users: Put your money at work. [Our chain abstraction demo](https://github.com/openfort-xyz/openfort-chain-abstraction) is built around basic time-locked vaults, but we will deploy yield-bearing vaults with different DeFi protocols.

Bridging ecosystems to create seamless liquidity for your users.
