Bounded Token
Approvals.

Built on Monad, Limes replaces blanket ERC-20 approvals with permission-based authorizations that are bounded by spending limits, expiry, and explicit transaction context.

Every wallet has a permission problem.

The biggest wallet drains rarely begin with a broken blockchain. They begin with a permission you approved months ago.

Today's ERC-20 approval model forces users into an impossible choice: approve every transaction individually, or give applications unlimited access indefinitely.

Limes makes the safer choice just as convenient.

From binary approvals to programmable permissions.

ERC-20 approvals are binary—they can only answer whether a contract can spend your tokens, not what you actually intended.

Forgotten or exploited approvals become the attack surface. Cleanup tools only help after the mistake has already happened. Limes makes boundaries the default.

How it works

One approval. Bounded forever.

STEP 01

Connect your wallet.

Authorize the open-source Limes contract once. Your assets remain entirely under your control.

STEP 02

Set real boundaries.

Choose the amount, expiry, and whether a permission should renew on a recurring schedule.

STEP 03

Understand the risk.

See dollar exposure and contextual facts about the spender before the approval is created.

STEP 04

Stay in control.

Review every permission, revoke instantly, and remove dormant approvals before they become liabilities.

Permission gateway

Grant any app a bounded permission.

Paste any spender address. Set a cap and expiry. LimesVault enforces both on-chain — the spender can never exceed what you set, and you can revoke instantly at any time.

"Test spender call" only works with the demo contract above. For your own spender, integrate via LimesVault's pull() API.

Approval scanner

What have you already approved?

Limes scans your wallet for existing unlimited or active approvals across common Monad tokens — the ones granted before you started using Limes. Reads are batched via Multicall3 for speed.

Connect your wallet to scan

Full approval scanning requires a dedicated RPC indexer. Coming post-launch — the scanner contract and Multicall3 integration are live and auditable on GitHub.

Core features

Every signal Limes provides is grounded in facts users can inspect and verify. No opaque reputation systems or proprietary trust scores.

Hard spending caps, mandatory expiry, recurring periods for subscriptions, and instant revocation.
