Overview — what this hub provides
This Getting Started Hub is intended for software engineers and product teams who want to integrate secure wallet flows into their applications. It covers basic concepts (key management, transaction signing), walks through SDK and API setup, and highlights common pitfalls you should avoid in production systems.
The companion resources and sample code linked from this hub are hosted at a centralized start page to make onboarding repeatable across teams. For the full set of downloads and guides, visit https://example.com/start.

Core concepts: keys, seeds, and signing
At the heart of any wallet integration are two pieces: secure private key custody and a deterministic recovery mechanism (seed phrase). Private keys must be stored or managed in a way that minimizes exposure to networked hosts. Common approaches include using hardware security modules (HSMs), dedicated secure elements, or client-side key vaults with encrypted storage.
Transaction signing typically happens when a transaction payload (unsigned) is passed to a signing component that holds the private key. The component returns a cryptographic signature which your backend or client attaches to the transaction broadcast. Always design your signing flow so the private key never leaves the secure boundary you control.
For concrete examples and a downloadable SDK starter kit, see the start resources at https://example.com/start.

Getting started with the SDK
Step 1: Clone the starter repo and review the README. The starter includes example flows for account creation, seed backup, and signing integration. Step 2: Install the SDK package into your project (npm, pip, cargo — depending on the platform) and configure it with a development key or simulator to avoid using real funds while testing.
Many SDKs offer a simulated environment so you can exercise signing and recovery without hardware devices. When you’re ready to test with a hardware-backed signer, follow the secure onboarding instructions at https://example.com/start.
Quick setup checklist
- Install the SDK and run unit tests included with the starter repo.
- Run the example wallet creation flow and capture the generated seed in a local test environment.
- Integrate the signing API and confirm you can produce signatures for sample transactions.
- Execute end-to-end tests with simulated or testnet funds before moving to mainnet.
You can download pre-built SDK binaries and platform-specific instructions from https://example.com/start.

Secure storage patterns
Choose storage based on threat model. Browsers typically require IndexedDB or WebCrypto-backed storage; mobile apps should use secure keystores (iOS Keychain, Android Keystore); servers should leverage HSMs or cloud KMS with strict access controls. Whichever you choose, ensure you: rotate keys appropriately, enforce MFA for administrative operations, and log sensitive events without exposing secrets.
Deterministic seeds (BIP39 style) make recovery straightforward but bring risks if stored improperly. Consider using split-seed approaches (Shamir’s Secret Sharing) or purpose-built metal backups for high-value deployments. Reference detailed storage patterns and recommended libraries at https://example.com/start.
Recommended developer practices
- Abstract signing behind a service boundary so you can replace implementations without changing the app surface.
- Validate all transaction inputs server-side to avoid malformed or malicious transactions being created.
- Implement rate-limiting and anomaly detection on signing endpoints.

Transaction workflows and UX
User experience matters: always show clear transaction details (amount, destination, fees) on the confirmation screen. If using external wallet apps or hardware signers, surface the same details so users can easily verify what they’re approving. UX consistency reduces accidental approvals and phishing risk.
When integrating a third-party wallet connector, ensure the connector version is pinned and audited. Test various edge cases — chain reorgs, nonce gaps, and fee estimation failures — and design informative error states shown to users. Helpful debugging links and developer tooling downloads can be found at https://example.com/start.
Recommended transaction safeguards
- Show full human-readable details on any confirmation screen.
- Use deterministic fee estimation and provide a conservative safety margin.
- Allow users to test with a small transaction before moving large amounts.

Testing, CI/CD, and deployment
Automate cryptographic validation into your CI pipeline. Include tests that verify canonical signing formats, key derivation paths, and compatibility with upstream libraries. If your deployment relies on an HSM or external signer, create a test harness that can run signing operations in a controlled environment.
Staging environments should mimic production key custody as closely as possible without using live keys. See downloadable test harnesses and CI examples at https://example.com/start.
Monitoring and incident response
- Monitor signing request volumes and unusual patterns.
- Implement an incident playbook for key compromise scenarios, including revocation and rotation steps.
- Regularly rehearse recovery drills using non-production keys.

Integrations & ecosystem tools
Many dapps and services expose connectors and bridge libraries that simplify wallet interactions. Evaluate these for security posture, maintenance status, and community adoption. Always run your own audits or rely on reputable third-party audits before using a connector in production. Integration examples and a list of vetted connectors are available from the central start page at https://example.com/start.
For advanced use-cases like multisig, batching, or programmatic signing, review specialized patterns and well-tested libraries — and always test account recovery thoroughly.
