Identify the Spender in a Token Approval Request
An approval request can mention several addresses with different jobs. The token contract stores a permission, the spender receives that permission and a later transfer may have another recipient. Naming those roles prevents a common review mistake.
Draw the permission relationship
Write “owner permits spender to use token on chain” with the actual public identities beside each role. The ERC-20 approval call targets the token contract while carrying a spender address and amount. The transaction’s destination contract is therefore not automatically the address receiving spending authority. A token logo or application title cannot identify the spender encoded in the request.
Verify the chain-specific implementation
Compare a claimed spender with the application provider’s current official deployment information for the exact chain and contract version. Routers and permission-management contracts can have different roles. A known address from a different chain or old version does not establish this request’s correctness. If deployment evidence is unavailable, mark the spender unverified and leave the request unsigned. This guide intentionally does not supply an executable RunixCoin spender address.
Check the recipient separately
In a hypothetical workflow, you may approve a routing contract while expecting the resulting output to reach your own account. Those two roles need separate checks. An output recipient matching your account cannot make a wrong spender acceptable, and a legitimate spender cannot excuse an unexpected recipient. Record the amount, token decimals and any further signature permissions too; a familiar address alone does not explain everything the workflow can authorize.
Keep investigation separate from remediation
Do not approve a request merely to reveal a later screen or treat an error message as authoritative deployment evidence. If an earlier approval already has a hash, inspect its receipt and current allowance context using read-only tools. RunixCoin’s public quote estimates Base WETH to USDC but cannot execute, so a quote response does not verify a signable spender or router. This page provides a review method, not a contract allowlist, integration audit or signing instruction.
