DevWallet

DevWallet enhances your Solidity development workflow. Works both with Anvil and Hardhat 3.

DevWallet is a developer wallet and DevTools for local Ethereum nodes: Foundry's Anvil and Hardhat 3. It lives in Chrome's side panel, next to the dApp you're building. Inspect and change your chain without leaving the browser: accounts, balances, nonces, blocks, mining and contracts. DevWallet is also a real injected wallet, so any dApp can connect to it. Act as one of the node's accounts, or impersonate any address on the network. NEW IN 3.0: SMART ACCOUNTS • Every dev account is an EIP-7702 smart account, delegated to Kernel v3.3 at its own address. Switch any account back to a plain account. • Sends from a smart account go out as ERC-4337 v0.7 user operations, paid by DevWallet's own sponsor and paymaster on your node. • EIP-5792 v2: wallet_sendCalls, wallet_getCallsStatus, wallet_getCapabilities and wallet_showCallsStatus, with atomic batches. • Every approval is simulated first. It shows who pays, what it costs, the balance changes and each call, decoded. • Batch queue: collect transactions from one or more dApps, reorder or drop them, and sign them as one. • Activity opens a handleOps transaction into its user operation, paymaster and calls. DEVTOOLS • Switch between the node's funded accounts, or paste any address to impersonate it. • Set balances and nonces, and give accounts names. • Auto, interval or manual mining, with snapshot and revert. • Browse blocks and transactions, pending ones included, with decoded calldata and logs. • Import contracts and their ABIs from your Foundry or Hardhat project, or let DevWallet find contracts deployed to the node. Read and write them from the panel. • ERC-20 tokens are detected, and you can import and transfer them. WORKS NEXT TO YOUR WALLET DevWallet announces itself through EIP-6963, so it sits alongside other browser wallets without taking over window.ethereum.
