What is YAB?

Yet Another Bridge (YAB) is the cheapest, fastest and most secure bridge solution from Starknet and ZKSync to Ethereum, and from Ethereum to Starknet and ZKSync

What makes YAB different from other bridge solutions?

Bridges are generally insecure and economically inefficient. They exhibit an asymmetry between users and bridge operators, where users can easily lose funds. What we propose different from other solutions is a bridge design that is simple, modular, and utilizes multi-storage proofs and the native messaging system between Ethereum and Layer 2 networks (L2s) as a fallback mechanism.

How much time does it take to bridge?

From the user's perspective, the bridging is completed in less than 30 seconds, or as little time it takes for the market maker to observe the user's deposit and execute a transfer.

From the market maker’s perspective, they will be able to receive back the money after paying the user and sending a message using the native messaging system. It takes less than 30 seconds, due to the time it takes to make a transaction in Ethereum and the L2’s sequencer receiving the message.

Storage proofs are also implemented but they are not in use because they are useful to scale and bridge from multiple L2 chains. This normally takes between 5 and 15 minutes.

How much does it cost to bridge?

The base cost of YAB is similar to an ERC20 transfer plus the cost of proving the state of the L1 and L2. Therefore, the bridge's final cost would be approximately $15.

What chains are currently supported?

Both Starknet and ZKSync are supported by YAB.

We are working on integrating almost every other rollup in the near future, so stay tuned for further updates!
