Reducing cross-border settlement costs by 60% with on-chain automation

Client: UK Fintech (name withheld by NDA)

63%
Fee reduction

Settlement time

Ops time saved/wk

The Problem

A UK-based payments fintech was processing cross-border settlements through a chain of correspondent banks, incurring 3–5% in fees and 2–3 day delays. Manual reconciliation was consuming 40 hours of operations time per week.

Our Approach

We conducted a 6-week discovery and architecture phase, evaluating Stellar, Ripple, and a private Ethereum network. We recommended and implemented a Polygon-based settlement layer with smart contract escrow, integrating with the client's existing core banking system via a custom API bridge.

The Result

Settlement fees fell from an average of 3.8% to 1.4% — a 63% reduction. Settlement time dropped from 2.5 days to under 4 hours. Operations reconciliation time fell from 40 hours per week to 6 hours. The system processed £4.2M in its first month of live operation without incident.

“Alphaveta gave us an honest assessment before we committed a penny. They told us which parts of our process blockchain could genuinely improve and which parts it couldn't. That candour saved us from a much more expensive mistake.”

Eliminating £1.6M in annual warranty fraud with blockchain product authentication

Client: Consumer Electronics Manufacturer

Product lines covered

The Problem

A consumer electronics brand was losing over £2M annually to counterfeit products and warranty fraud. Customers had no reliable way to verify product authenticity, and the company had no tamper-proof record of genuine product provenance.

Our Approach

We designed a Hyperledger Fabric-based provenance system where each product received a unique on-chain identity at manufacture. QR codes and NFC tags linked physical products to their on-chain record. We built a consumer-facing verification app and integrated the system with the client's existing ERP.

The Result

Counterfeit incidents fell by 74% in the first year. Warranty fraud losses dropped by £1.6M. The solution was adopted across 14 product lines within 8 months of launch. Consumer trust scores improved by 22 points in post-launch brand surveys.

“The ROI was clear within the first quarter. But beyond the numbers, we now have a provenance system that our retail partners trust — and that's opened doors to distribution agreements we couldn't have accessed before.”

Preventing a critical reentrancy vulnerability from reaching mainnet

Client: DeFi Protocol (pre-launch)

Critical issues found

Total findings
0
Post-launch incidents

The Problem

A DeFi protocol was 3 weeks from mainnet launch with $8M in committed liquidity. Their internal team had reviewed the smart contracts but had no formal audit process. A previous protocol in the same category had lost $6M to a reentrancy attack.

Our Approach

We conducted a full line-by-line audit of 4,200 lines of Solidity across 11 contracts. Our process combined automated static analysis (Slither, MythX) with manual review by two senior engineers. We produced a severity-ranked report with specific remediation guidance for each finding.

The Result

We identified 1 critical vulnerability (a reentrancy flaw in the withdrawal function that could have drained the liquidity pool), 3 high-severity issues, and 7 medium/low findings. The critical issue was patched and re-audited within 5 days. The protocol launched on schedule with zero security incidents in its first 6 months.

“The critical vulnerability Alphaveta found would have been catastrophic. We had reviewed that code ourselves and missed it. The audit paid for itself before we even launched.”

Building the business case for blockchain traceability in a 12-carrier network

ROI (yr 1)

The Problem

A logistics group managing a 12-carrier network had persistent disputes over cargo handoffs — who had custody, when, and in what condition. Manual documentation was creating 3–4 week delays in dispute resolution and costing an estimated £800K annually in unresolved claims.

Our Approach

We ran a 6-week strategy engagement: mapping the existing dispute process, quantifying the cost of each failure mode, evaluating consortium blockchain options, and producing a board-ready business case. We recommended a Hyperledger Besu consortium chain with all 12 carriers as nodes.

The Result

The board approved a £340K implementation budget based on our business case. The projected ROI was 2.4x in year one. Implementation (by the client's internal team, following our architecture) completed in 14 weeks. Dispute resolution time fell from 3–4 weeks to 48 hours.

“We had been talking about blockchain for two years without being able to justify the investment. Alphaveta gave us the numbers and the architecture to make the case. The board approved it in one meeting.”
