Have you ever encountered the following frustrating situations in the world of Crypto Assets? Constantly having to jump between Wallets during payments, and if you accidentally click wrong, all your efforts go to waste; cross-chain payments are even more cumbersome, requiring multiple steps such as switching networks, authorizing, confirming, signing, and in the end, the payment might still fail. The root of these problems lies in the existing connection protocol's lack of a 'payment memory' function; once a session is interrupted, all previously confirmed information is lost.

To address these pain points, WalletConnect has launched a series of innovative features:

1. Introduce 'Session Payment Memory' to record the payment path during connection.
2. Support direct calls to 'preset transaction packages' within DApps to avoid duplicate signatures.
3. Keep the Session connection during multi-chain switching, users only need to sign once to complete the operation.
4. Allow DApps to add 'limit permissions' for connections to automatically complete transactions within the authorized scope.

Imagine if you set 'allow orders not exceeding 30U on the Arbitrum chain', the application would no longer frequently request your signature, and the payment process would become as smooth as facial recognition.

In this revolutionary payment experience, WCT (WalletConnect Token) plays a key role:

- Users can activate the 'Simplified Payment Session' by staking WCT.
- Network nodes are responsible for maintaining the records of payment authorization trails.
- The authorization cost generated by 'Session Direct Payment' is borne by the WCT network.
- Advanced permissions (such as multi-chain, high limits, high-frequency trading) require more WCT weight.

Overall, the upgrade of WalletConnect aims to fundamentally change the user's cross-chain payment experience, making complex operations simple and straightforward, paving the way for the popularization of the blockchain world.
