Product Overview

Blockchain Development

What it is

XBase Blockchain enables organisations to build on-chain systems: blockchain integration into existing products, custody and wallet systems, smart contract development and review, token issuance infrastructure, chain data APIs and Web3 applications.

The problem it solves

In on-chain systems, mistakes cannot be reversed. Key management, signing flows, contract upgrade strategy and consistency with off-chain systems must be designed before the product is written. We make those decisions up front, according to the organisation's risk appetite.

Who it is for

For financial institutions building digital asset custody and transfer infrastructure, companies issuing tokens and startups building Web3 products.

Core Features

Core Features

  • Blockchain Integration

    Adding deposit, withdrawal and chain monitoring capabilities to existing systems.

  • Wallet Systems

    Hot/cold wallet architecture, multi-signature and MPC-based custody flows.

  • Smart Contracts

    Development, testing and upgrade strategy for EVM-compatible contracts.

  • Token Infrastructure

    Token issuance, distribution and lifecycle management with compliance controls.

  • Blockchain APIs

    Normalised APIs for chain data, balances, transactions and event streams.

  • Web3 Systems

    Wallet connection, signing and on-chain interaction layers.

  • On-chain Applications

    Applications where on-chain and off-chain components work consistently.

How It Works

How It Works

  1. 01

    Architecture decisions

    Chain selection, custody model, key management and upgrade strategy are defined.

  2. 02

    Contract and wallet design

    Contracts and signing flows are designed together with a threat model.

  3. 03

    Development and testing

    Unit, integration and simulation tests; validation on test networks.

  4. 04

    Review

    Internal review and, where required, independent audit.

  5. 05

    Release and monitoring

    Mainnet release, chain monitoring, alerts and incident response.

Architecture

Architecture

On-chain components are kept as small as possible; most business logic runs off-chain in auditable services. All chain interaction passes through a single signing and broadcasting layer.
