ERC20 Paymaster Support, Connect UI Transactions, and readContract msg.sender

Greg

Using Account Abstraction, you can now pay for gas using any ERC20! Just set the erc20Paymaster override to the paymaster of your choice when sending a smart account transaction.

The Connect UI now shows transactions completed during the current session. This is enabled automatically, there's no additional configuration needed! We're working on making this history persistent beyond a single session.

You can now specify a from field when reading contracts with readContract or useReadContract. This is useful for contract methods that may behave differently based on the msg.sender.

• Connect UI components now respect custom RPC passed via the chain prop
• Improved gas buffer when gas estimation fails on Pay transactions
