API Keys vs Wallet Private Keys
Explain the different authority of data-access credentials and wallet signing keys, so read-only integrations never request spending secrets unnecessarily.
Overview
When translating these concepts into an integration, keep the scope described by the wallet history api with the result. The examples in wallet transaction history and smart contract event logs show how the same distinction affects neighbouring data questions.
An API key authorises requests to a service under its access policy. A wallet private key can authorise blockchain actions under the wallet’s rules. They are not interchangeable credentials.
Understand the authority boundary
A data API key can expose account usage or incur service costs, so it still requires protection. But it should not grant wallet signing authority unless a separate product explicitly implements that capability. A public wallet address can often support read-only queries without any private key. Keep authentication to the data service separate from ownership verification of a wallet.
Worked example: importing public history
A backend receives a public wallet address and uses its own authorised data-service credential to fetch history. It never asks the user for a seed phrase. If the application needs to verify wallet control, it can use an appropriate challenge signature flow rather than requesting the signing secret itself.
Design forms and documentation clearly
Name credential fields precisely and explain their purpose. Reject seed phrases or private keys in read-only configuration where practical, without logging submitted secrets. Test accidental pasting and safe validation errors. Never include reusable examples that resemble real credentials in browser bundles or public reports.
A practical acceptance test
Use a read-only import form with a public address and synthetic service credential. Assert that no signing secret is requested or transmitted. Simulate accidental seed-like input and check safe rejection without logging it. The backend access credential must remain protected even though the test proves it cannot authorise a wallet transaction.
Questions about the topic
Frequently asked questions
Is a seed phrase needed to read public transactions?
No. Read-only history should not require spending secrets.
Are API keys harmless because they cannot sign?
No. They can still expose data access or permit billable usage.
