What is txSync?

txSync helps teams building on ZKsync ship faster by combining an asset portal, an Ethereum-to-ZKsync bridge, a no-code paymaster builder called Tsuko, and a contract playground. Developers can deploy custom paymasters to sponsor gas, automate transactions, and integrate ZKsync features through SDKs without managing the underlying infrastructure.
