TANGIBLE RESULTS
Business Outcomes of Legacy System to Atomic Swap Migration
Migrating from a centralized, custodial exchange to a non-custodial atomic swap protocol delivers measurable improvements in security, cost, and user experience. Here are the concrete outcomes we deliver.
01
Eliminate Counterparty Risk
Replace trust-based, centralized settlement with cryptographic atomic swaps. Users retain custody of their assets throughout the trade, removing the risk of exchange insolvency or fraud.
0%
Custodial Risk
100%
User Control
02
Reduce Operational Costs by 60-80%
Cut out intermediary fees, withdrawal charges, and the overhead of maintaining complex order-matching engines. Settle trades directly on-chain with predictable gas costs.

03
Achieve Global Compliance by Design
Atomic swaps are peer-to-peer, non-custodial transactions. This architecture significantly reduces your platform's regulatory surface area and liability compared to operating a centralized exchange.

Technical & Operational Comparison
Legacy Settlement vs. Atomic Swap Infrastructure
A detailed comparison of traditional financial settlement systems against modern atomic swap infrastructure, highlighting the technical and business advantages of migration.
| Comparison Factor | Legacy Settlement Systems | Atomic Swap Infrastructure |
|---|---|---|
Settlement Finality | T+2 days (or longer) | Atomic (< 2 seconds) |
Counterparty Risk | High (requires trusted intermediaries) | Eliminated (trustless execution) |
Operational Cost | $15-$50 per transaction | < $0.01 per transaction |
Development Timeline | 6-12 months for integration | 4-8 weeks for full deployment |
Cross-Chain Capability | None (siloed systems) | Native (EVM, Cosmos, Solana, etc.) |
Liquidity Requirements | High (pre-funded nostro accounts) | Minimal (on-demand via DEXs) |
Audit & Compliance Overhead | Manual, periodic reconciliations | Programmatic, real-time transparency |
Failure Points | Multiple (banks, custodians, networks) | Single (smart contract security) |
Time to Market for New Products | 9-18 months | 2-4 months |

Our Phased Migration Methodology
We execute legacy system migrations using a proven, step-by-step framework designed to eliminate downtime, prevent data loss, and ensure a seamless transition to atomic swap infrastructure.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing system, mapping all dependencies, transaction flows, and data structures. This phase delivers a detailed migration blueprint and risk assessment, ensuring zero surprises.

Phase 2: Parallel Environment Build
We develop and deploy the new atomic swap infrastructure (e.g., using Solidity, CosmWasm) in a sandboxed environment that runs in parallel with your legacy system. This allows for real-time validation and testing without disrupting live operations.

Technical & Process Details
Atomic Swap Migration FAQs
Answers to the most common questions from CTOs and technical leads planning a migration from legacy token bridges to atomic swaps.
A standard migration for a single token pair takes 2-4 weeks from kickoff to mainnet deployment. This includes architecture review, smart contract development, security audit integration, and final deployment. Complex protocols with multiple assets or custom logic may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during the scoping phase.
