Blockchain made fast and easy

Nexledger's standard service API allows you to focus on creating business value without worrying about choosing decentralized consensus technologies for various blockchain. Not only can customers configure their own blockchain network, but they can also quickly utilize the blockchain features they want through a BaaS(Blockchain-as-a-Service) subscription.

Major Services

Efficient development is possible by providing various blockchain cores as APIs

  • Customers to use blockchain platform 217 or more
  • Blockchain technology used for PoC Global Top 7 (Gartner, 2019)
  • Global top 50 companies in blockchain Selected 3 years in a row (Forbes, 2019-2021)





  • Scalability

    Nexledger Universal supports real-time configurations such as load balancing and horizontal scaling. It is a highly flexible platform securing its performance even after when new nodes are added.

  • Performance

    Nexledger Accelerator is Samsung SDS’s proprietary technology that speeds up blockchain transaction throughput. Accelerates throughput up to 15 times via batch processing & insertion between the blockchain platform and client.(*compared to Hyperledger Fabric)

  • Interoperability

    Expediter, a Nexledger Universal’s specialized technology, supports interoperability between Heterogeneous blockchain. you may sent same transaction to multiple/heterogeneous blockchain.

  • Security

    Apply access control for nodes, compliance with encryption standards, and network point-to-point encryption for complete data security. In additional, you may build a flexible and secure data sharing system by on/off-chain two-way processing technology.

Paperless Service

Provide simple and safe document contract and storage service through blockchain.

  • Convenient Standard API : Reduce direct development scope through API linkage to save manpower/time/cost and eliminate direct operation/management of blockchain platforms.
  • High Security : Data encryption for customer information protection, channel separation configuration, independent network separation to prevent mutual interference and isolate data.

* New BaaS services are continuously being added.

Token Service

We provide a service to register tangible and intangible real asset information as digital assets on the blockchain and trade rights to them.

  • You can manage tokens by type.
    Payment Token
    NFT (Non Fungible Token)
  • Convenient standard API: Save time and money without having to operate or manage the platform directly.
  • High security: High security is ensured by data encryption for customer information protection, channel isolation configuration, independent network isolation, etc.
  • Efficient Token Management: Templated token attributes can be quickly and easily applied to different business environments, providing management capabilities across the Token Life Cycle of Creation-Manufacturing-Generation-Return-Disposal-Delete.
Universal API

    Paperless Service

    Blockchain-based original storage, authenticity verification subscription service

    What's a Paperless Service?
    Samsung SDS Paperless Service is a blockchain-powered, simple and safe e-document management system. Embracing blockchain technology, our service secures and manages various usiness documents with the other info. such as time and date when it was signed/modified and the authentication/processing info..
    Guarantee document integrity by providing timestamp and storage info.
    Secure document from tampering by storing the original document in blockchain
    Monitor storage and usage status in real-time
    Simple integration with existing legacy system via APIs

    Pricing plans
    Paperless services are available on a per-usage pricing, or monthly membership pricing.
    Pricing Plan Per-Usage (Write Transaction) Pricing Monthly Membership Pricing
    Description This pricing is a pay-as-you-go option. The total monthly transaction will be counted and charged for. If you are expecting low volume of transaction on a monthly basis, this pricing would be suitable This pricing is a monthly fee option. The membership fee covers up to 10,000 transactions per month, and if the total transaction exceeds 10,000, additional fee will be incurred.
    Fee Calculation # of Transaction * Rates

    Monthly Fee

    * (+ # of Transaction exceeding 10,000 TX * Rates)

    If the original documents are stored, data storage fee will be separately charged (MB/Year)
    ex) #TX*rate + data storage fee or Membership fee + data storage fee
