Token approvals for ERC-20 can expose users to excessive permissions and confusing UX, leading to funds being spent by apps without clear consent. This Skill provides UX patterns to standardize approvals, improve visibility, and support safe revocation across common ERC-20 flows.
Apply exact-amount approvals by default and implement a one-click revoke flow for any granted permissions.

Safe ERC-20 token approvals are implemented by defaulting to exact-amount spending limits instead of unlimited allowances. This approach standardizes user consent, ensuring applications only spend the explicitly required token amount during interactions.
The Permit2 workflow for gasless ERC-20 approvals enables off-chain signature collection to authorize token spending without requiring on-chain transactions. It supports both AllowanceTransfer and SignatureTransfer patterns to execute permissioned transfers securely.
Batching ERC-20 token approvals and contract interactions atomically is achieved using the EIP-5792 standard. This workflow groups the approve action and the subsequent contract call together when the connected wallet supports atomic batching.
Exact-amount ERC-20 approvals fail with USDT because its contract requires resetting the allowance to zero before changing it to a new value. Implementing zero-reset handling ensures the approval transaction processes correctly for non-standard tokens.
Designing an in-app UI to view and revoke active ERC-20 approvals involves implementing a clear post-approval display with contract name resolution. This provides human-readable permission summaries and a one-click revoke flow for granted spending access.
Displaying human-readable contract names and permission summaries for ERC-20 approvals is supported by resolving contract addresses to readable names. This explicit summary clarifies exactly what permissions are granted before users sign the transaction.
