With Candide InstaGas, Revoke increases user protection with zero gas fees.

For years, Revoke has provided a public good helping individuals manage smart contract permissions. By allowing users to view and revoke token approvals, Revoke.cash prevents asset drain attacks, mitigates risks from compromised dApps, and provides control in the decentralized ecosystem.

However, gas fees created friction. Revoking permissions. while crucial for security. required users to have native tokens in their wallet, leading to delays or inaction.

“While it’s now possible to batch unlimited revocations, the showstopper is always the same: if you’re out of native tokens for gas, you simply can’t act.” — Rosco Kalis, CTO of Revoke

The Revoke Imperative: Security Without Friction

The team identified three core challenges:

Every hour a dangerous approval sits unrevoked is an hour of exposure. The answer needed to be instant, not gated behind a trip to an exchange.

InstaGas Delivers Gas-Free Transactions

Revoke.cash chose Candide InstaGas for two reasons:

Precise gas policy control. Through Candide’s dashboard, the team configured exactly which transactions to sponsor, on which networks, and under what conditions. No blanket subsidies. no waste.

Minimal codebase changes. InstaGas adheres to Ethereum standards, requiring only minor adjustments to their existing viem library integration. The core product stayed intact.

“Implementing gasless revocations was a significant goal for us. Candide InstaGas allowed us to set up precise gas policies with very minimal changes to our existing codebase.” — Rosco Kalis, CTO of Revoke

What This Unlocks for Users

With gas sponsorship in place, any user who needs to revoke a token approval can act immediately. No native token balance required. No side trips to an exchange. No delay while a security threat compounds.

The result is a security tool that actually gets used when it matters.

Key Lessons for DApp Builders

Rosco’s experience surfaced two principles worth noting for any team evaluating gasless infrastructure:

  1. Partner with teams that understand your specific use case. Standard APIs often fail the nuanced requirements of security-critical applications.
  2. Choose tools with minimal learning curves. As Rosco put it: “If a tool requires a manual, something’s gone wrong.” The right infrastructure should feel obvious.
