A wallet connection button is one small part of a blockchain application. A useful development brief also explains who authorises actions, which network the application supports and what the user sees while a transaction is unresolved.
This buyer’s guide covers wallet and transaction-state requirements for Ethereum-compatible applications. Other networks may use different concepts and interfaces. Use it to scope Web3 applications and protocol integrations, with the exact supported networks agreed before development.
1. Choose the wallet and account model
State whether users bring an existing wallet or the product needs an embedded account experience. Ask who controls signing, how recovery works and which responsibilities belong to your business, the wallet provider and the user. Key management deserves a separate security review and written operating plan.
List the supported desktop and mobile journeys. Include account switching, network switching and disconnecting. The Ethereum provider standard, EIP-1193, defines account and chain change events, along with errors for rejected requests and disconnected providers. These are useful acceptance scenarios, not just developer implementation details.
2. Describe exactly what users authorise
Separate connecting a wallet, signing a message and submitting a transaction in the interface and project brief. Explain the purpose of each request before opening the wallet. Ask the supplier to document any token permissions, the intended recipient or contract, the network and the displayed amount.
A changed account or network can invalidate information shown earlier. Agree when the application must refresh its preview or stop the flow. A cancelled wallet prompt should leave the user with a clear next step rather than an unexplained loading screen.
- Check account and networkConfirm that the selected wallet fits the requested action.
- Review and request signingShow the action and expected costs; rejection stops this path.
- Track submissionKeep the transaction reference while the result is pending.
- Read the execution resultDistinguish successful execution from failure.
- Apply the confirmation policyWait for the agreed network condition before the business handoff.
This simplified, illustrative workflow is a scoping aid. It is not a client case study; recovery paths must be specified separately.
3. Give each transaction state a meaning
Agree separate messages for awaiting wallet approval, submitting, pending, successful execution, failed execution and unresolved status. Define which events move the interface between them and which source supplies the evidence.
Ethereum’s transaction documentation describes broadcasting, block inclusion and later finality. A transaction reference alone is insufficient evidence that the intended operation finished. Decide when your business process may continue, and avoid promising a universal completion time across networks.
For Ethereum, the JSON-RPC documentation describes transaction receipts and their success or failure status. Ask how the application checks the receipt and, where relevant, the expected contract event or resulting state. Technical execution and your application’s business outcome need clearly defined checks.
4. Budget for unresolved and changing results
Ask the supplier to demonstrate a slow transaction, a failed transaction, a lost connection and a page reload during processing. Include replacement or dropped-transaction handling if those cases are supported by the selected wallet and network.
The interface should preserve enough context to investigate uncertainty. Agree how users find their transaction reference, what support can inspect and when the application will retry a read. Repeating a read and asking the user to authorise another transaction have different consequences.
Specify the response if a previously observed block is reorganised before your confirmation policy is satisfied. Choose the confirmation policy with the technical team for each supported network and action; do not copy a fixed block count without understanding its purpose.
Buyer’s scoping checklist
- Supported networks, wallets, devices and account models
- Named signing, recovery and administrative responsibilities
- Human-readable previews of contract actions and permissions
- Account-change, wrong-network and rejected-request behaviour
- Pending, execution-result and confirmation-state definitions
- Reload, provider outage and unresolved-transaction tests
- Transaction references and support tools without exposed secrets
- Network fees, provider charges, monitoring and maintenance ownership
Keep automation boundaries explicit
If the application also includes AI, identify whether it explains information, proposes actions or can initiate a signing request. For an AI and blockchain integration, require a clear boundary between generated suggestions and transaction authority. Include approval and rejection tests in the brief.
