About this app
WHAT IT DOES
This tool sets spending limits for addresses, controlling how much can be spent within a given period. It reads and displays the current spending limit, new spending limit, current spending used (amount already spent), spending limit period (time window for the limit), spending limit status (active, pending, exceeded, or expired), account balance, chain ID, and limit history. Beyond read-only access, the tool lets you execute the five key actions: set a new spending limit for an address, approve a spending limit change (if required), batch set spending limits for multiple addresses in one transaction, claim limit change confirmation, and cancel a pending limit change.
HOW TO USE
Connect your wallet and select the network. Enter the spending limit contract address, optionally the address to set the limit for (defaults to your connected wallet), the new spending limit amount, and an optional limit period (in seconds). Click "Load State" to fetch the current limit, spending used, limit period, status, and limit history. Review the current limit, spending used, and status. If you are the account owner and have sufficient balance, click "Set Limit" to apply the new spending limit. If the contract requires explicit approval, click "Approve" first. To set limits for multiple addresses at once, click "Batch Set." Click "Claim" to confirm a completed limit change, or "Cancel" to cancel a pending change. Each transaction shows confirmation and gas cost reporting.
TECHNICAL MECHANISM
The tool interacts with a spending limit contract that manages per-address spending limits. The setSpendingLimit() function sets a new limit for a specific address, controlling how much can be spent from that address within the limit period. The setSpendingLimitWithPeriod() function additionally sets the time window. The contract validates that the caller is authorized to set the limit. The spendingUsed() function tracks the amount already spent. The limitStatus() function returns the current state (0 = active, 1 = pending, 2 = exceeded, 3 = expired). Batch setting uses setLimitBatch() with arrays of addresses and limits. The tool fetches limit history via limitHistory().
WHAT IT CANNOT SEE
Cannot verify that the spending limit is appropriate or that the user will not exceed it. Relies entirely on the spending limit contract's verification and the destination chain's final state. Cannot detect if the user is overspending off-chain, if the limit is being bypassed, or if the contract's calculations are correct.
PLEASE NOTE — EVM CHAINS ONLY
Supports Ethereum, Polygon, Optimism, Arbitrum, Base and similar EVM chains. The limit contract must implement currentLimit(), spendingUsed(), limitPeriod(), limitStatus(), setSpendingLimit(), setSpendingLimitWithPeriod(), approveLimitChange(), setLimitBatch(), claimLimitChange(), cancelLimitChange(), and limitHistory(). The tool is read-write: it signs transactions for setting, approval, batch setting, claiming, and cancellation. Always verify the contract address and limit parameters before submitting.
