Attestation SDK ​

Use Cases
Real-world applications of secure attestation management

Use Cases ​

The Attestation SDK—with its Core SDK, Backend, and CLI—powers a range of scenarios requiring trust, verifiability, and scalability. Built for digital payment commitments and mutual attestations, it leverages HD wallets, cryptographic signatures, and a robust lifecycle to tackle challenges in finance, agreements, and beyond. Below are key use cases where Attestify shines, showing how it delivers value in practical settings.

1. Securing Digital Payment Commitments ​

Ensuring trust in financial agreements

Scenario ​

A bank and a corporate client need to agree on a digital payment commitment—say, a $10M trade settlement. Traditional systems rely on slow, centralized verification, risking delays or disputes.

How Attestify Helps ​

  • Initiation: The bank (committer) creates a commitment via the SDK, specifying asset details (e.g., $10M, USD) and signs it with their HD wallet-derived key.
  • Acknowledgment: The client (committee) verifies and countersigns using the CLI or backend API, moving the state to Acknowledged.
  • Effectiveness: Both parties confirm the terms, transitioning to Effective with dual signatures.
  • Discharge: Upon settlement, the bank discharges the commitment, cryptographically proving fulfillment.

Benefits ​

  • Speed: Instant state transitions replace days-long processes.
  • Trust: Multi-signature verification ensures non-repudiation.
  • Auditability: MongoDB logs every step for compliance (e.g., BAFT protocol).

2. Mutual Attestations for Business Agreements ​

Proving agreement between parties

Scenario ​

Two companies negotiate a supply chain contract—e.g., delivering 100 tons of steel. They need a tamper-proof way to confirm terms without intermediaries.

How Attestify Helps ​

  • CLI Workflow: Company A initiates the attestation (e.g., node index.js create-commitment --assetName "Steel" --quantity 100), storing it via the backend.
  • Acknowledgment: Company B acknowledges it with their signature (acknowledge-commitment), verified by the SDK’s SignatureService.
  • Acceptance: Company A accepts, locking in the deal.
  • Discharge: After delivery, both sign to discharge, completing the cycle.

Benefits ​

  • Simplicity: The CLI abstracts complexity for non-technical users.
  • Security: secp256k1 signatures prevent tampering.
  • Flexibility: Custom derivation paths support multi-blockchain environments.

3. Decentralized Finance (DeFi) Workflows ​

Powering trustless financial operations

Scenario ​

A DeFi platform needs to manage collateral commitments between lenders and borrowers, integrating with wallets like MetaMask.

How Attestify Helps ​

  • External Signing: The borrower initiates a commitment via the SDK, signing with MetaMask (signWithMetaMask).
  • Backend Storage: The lender acknowledges it through the /acknowledge-attestation API, persisted in MongoDB.
  • State Management: The SDK validates transitions (Initiated → Effective), ensuring collateral is locked.
  • Release: After repayment, the discharge phase unlocks funds.

Benefits ​

  • Compatibility: Works with Web3 wallets out of the box.
  • Scale: Handles high transaction volumes with lightweight design.
  • Reliability: State validation prevents invalid transitions.

4. Supply Chain Provenance ​

Tracking goods with verifiable commitments

Scenario ​

A retailer wants to prove the origin of organic coffee beans to consumers, ensuring suppliers meet sustainability commitments.

How Attestify Helps ​

  • Commitment Creation: The supplier attests to sourcing details (e.g., 500kg from Farm X) using the CLI.
  • Verification: The retailer acknowledges via the backend, confirming receipt.
  • Public Proof: The Effective state, signed by both, is shared as a QR code for consumer trust.
  • Completion: Discharge occurs upon sale, closing the loop.

Benefits ​

  • Transparency: Cryptographic proof builds consumer confidence.
  • Efficiency: Automates multi-party verification.
  • Persistence: Backend logs ensure traceability.

Why These Matter ​

These use cases highlight Attestify’s versatility:

  • Financial Trust: Secures payments and agreements with cryptographic rigor.
  • Operational Efficiency: Automates workflows across industries.
  • Developer Enablement: Simplifies integration into diverse systems.

From banks to DeFi platforms to supply chains, Attestify turns complex attestation needs into streamlined, secure solutions.
