Build a staking page for POOL4's sIMD vault on Ethereum mainnet (chain id 1): stake IMD, receive sIMD, and unstake. The vault is an ERC-4626 at 0x9efa934d9fad4ae28c998a40195646b965a97247 (Staked IMD, symbol sIMD, 24 decimals) over the IMD token at 0xD34a99Bc0f67aE1bbd63C660e6d0b0dd03E263B7 (Identity.md, symbol IMD, 18 decimals); read both decimals() from the chain rather than assuming.

Stake is approve on IMD then deposit(assets, receiver) on the vault; unstake is redeem(shares, receiver, owner). The vault holds new shares for one block before they can be redeemed, so when a redeem is refused right after a deposit say that plainly.

Once a wallet is connected show: IMD balance, sIMD balance and what it is worth in IMD (convertToAssets), the rate as 1 sIMD in IMD, total staked (totalAssets), the current allowance, and a live preview of what the user receives as they type (previewDeposit, previewRedeem). Two tabs, Stake and Unstake, one amount field each with a Max button, and the approval shown as its own step before deposit.

Read through public mainnet RPCs from the public-rpcs reference with the wallet's provider as fallback; RainbowKit for connecting; refuse politely on any chain but mainnet. Link the vault and the token on Etherscan.

Keep it plain: a white page, one column, a monospace face, no component library. Title the page 'Stake IMD'. Nothing secret in the repository.

  3. Adversarial reviewfound 3 medium

    Wrote three medium-severity findings to .imd-findings.json:

    • Unsupported wallet chains bypass the mainnet guard.
    • Mined transaction reverts display no failure message.
    • RPC fallback uses the global provider instead of the connected wallet.

    Each includes a concrete reproduction. Source files remain unchanged.

    • mediumCheck the connected wallet chain instead of the configured chainsrc/App.tsx:35

      useChainId reports Wagmi's configured chain, which remains 1 when the connected wallet switches to an unsupported chain because only mainnet is configured. Consequently wrongChain remains false and the required mainnet-only refusal and switch control are never shown. Reads and transaction controls remain active.

      Writes explicitly target chain 1, so this does not establish transactions being sent to Polygon.

      Connect an injected wallet on Ethereum, then switch it to Polygon (chain ID 137).

      The bundled Wagmi syncConnectedChain callback only updates the config chain when the new chain is in configured chains; invoking that callback with 137 leaves config.chainId=1.

      App computes wrongChain=false.

      Expected: the Ethereum-mainnet-only message and switch button with staking controls hidden.

      Actual: the staking interface stays available despite the connected account's chain being 137.

    • mediumDisplay receipt errors for transactions that revert after submissionsrc/App.tsx:124

      currentError includes only useWriteContract errors and ignores approvalReceipt.error, depositReceipt.error and redeemReceipt.error. A wallet can successfully submit a transaction that subsequently reverts; the bundled Wagmi receipt action throws for such a receipt, so neither the success effects nor the rendered error handle this failure. Users receive no indication that their submitted action failed.

      Connect on mainnet with a valid redeem amount, submit redeem successfully and have it mined with receipt status 0x0 (for example, include it in the same block as a deposit affecting the owner's one-block hold, using an explicit gas limit). useWriteContract returns a hash with redeem.error=null; useWaitForTransactionReceipt reports an error for the reverted receipt.

      With approval.error and deposit.error also null, currentError remains null.

      Expected: a transaction failure message, including the one-block hold explanation for this redeem.

      Actual: confirmation loading ends without any failure message; the static hold note is the only explanation available.

      The same missing error handling affects reverted approvals and deposits.

    • mediumUse the connected provider for the public RPC fallbacksrc/main.tsx:20

      The fallback transport captures window.ethereum once at application startup instead of obtaining the connected connector's provider. Wagmi also discovers EIP-6963 wallets, which can differ from window.ethereum or exist without that global. Thus a functioning connected mainnet provider is not necessarily used when public endpoints fail, and a different global provider can supply data from another chain.

      Load with wallet A assigned to window.ethereum and wallet B announced through EIP-6963; connect B on mainnet.

      Make all three configured public RPCs unavailable and have A reject eth_call while B can serve mainnet calls.

      The transport list's last entry remains custom(A); no read is sent to B, and balances/decimals/previews fail to load.

      Expected: reads fall back to connected wallet B and staking remains usable.

      Actual: reads use unconnected A and fail.

      The fallback list is constructed before connection and is never updated when B is selected.
