v3.0.0

DevWallet 3.0 turns your node's dev accounts into smart accounts and moves the wallet into a redesigned side panel.

Highlights

• Smart accounts (EIP-7702, Kernel v3.3). Each dev account is delegated to Kernel at its own address. Switch any account to Plain under Advanced on the Account home.
• Sponsored sends (ERC-4337 v0.7). A smart account's sends go out as user operations paid by the DevWallet sponsor and paymaster. If the sponsor can't pay, the account pays, and the approval says why.
• EIP-5792 v2. wallet_sendCalls, wallet_getCallsStatus, wallet_getCapabilities and wallet_showCallsStatus, with atomic batches. Every approval is simulated first: the payer, the cost, the balance changes and each call, decoded.
• Batch queue. Collect sends from one or more dApps, reorder or drop them, and sign them as one transaction.
• User operations in Activity. handleOps transactions open into their user operation, paymaster and calls.
• A stricter page boundary. A site that isn't connected can only read the chain and connect, and the wallet UI can no longer be framed. See "What a site can do" in the README.
• Redesigned side panel and a new logo, the Docked D.

Coming from 2.x

• Existing dev accounts become smart the first time DevWallet checks a network. A smart account's sends then go through Kernel: the transaction's to is the EntryPoint (sponsored) or the account itself, and a sponsored send doesn't move the account's nonce. To keep plain transactions, switch the account to Plain.
• dApps that call cheat methods (anvil_*, evm_*) through the wallet must connect first.
• Hardhat with its default config: Sign anyway on a batch leaves the batch open; Discard it, or set throwOnTransactionFailures: false.

Known issues

• On Anvil, eth_accounts also lists the DevWallet sponsor (0xA346…45F3), because Anvil lists the accounts it impersonates.
