About the Client

Japaul Digital Solutions Limited

Japaul Digital Solutions Limited is an associate company of Japaul Gold and Ventures Plc, a Nigerian gold mining company that owns, mines, and produces gold behind every JPGC token. The company was created to lead the Group's expansion into the rapidly evolving digital assets ecosystem.

By leveraging federally-issued gold mining leases and independently audited reserves, Japaul Digital Solutions collateralises every token it issues with real, verifiable value, commissioning JPGold Coin (JPGC) and its companion JPG-NFT certificates as its flagship venture into tokenized real-world assets.

About the App

A borderless token for global commerce.

JPGold Coin (JPGC) envisions a borderless token that serves as a universal medium for exchange, investment, goods, and services, empowering global commerce without limits. Each JPGC token represents one gram of physical gold.

Alongside the token, JPG-NFT certificates give holders a verifiable, blockchain-based claim to future gold redemption and in-game mining rights, each one uniquely tracked on Solana blockchain. JPGC is listed on leading global exchange like BitMart, making it easily accessible for trading worldwide, 24 hours a day.

Beyond simple trading, JPGC integrates with DeFi protocols for staking, yield farming, and collateral, turning a gold-backed token into productive, on-chain capital rather than a static store of value.

The Challenge

Building a gold-backed token that trades like a native crypto asset.

JPGC combined real-world asset auditing, cross-chain bridging, both Token and NFT backed redemption rights, and multi-jurisdiction compliance into one coherent product. These were the six hardest problems we solved.

Real-World Asset Collateralization

Building transparent, verifiable proof-of-reserve that ties every JPGC token to federally-licensed gold mining leases and independently audited, physical reserves.

Cross-Chain Interoperability via Wormhole

Bridging JPGC across Solana and ethereum networks with Wormhole, so the token trades seamlessly on exchanges like BitMart without fragmenting liquidity or trust.

Solana SPL Token Architecture at Scale

Engineering a high-throughput SPL token and smart contract layer capable of supporting swaps, staking, and NFT issuance without network congestion.

Exchange Listing & Liquidity Integration

Integrating with centralized exchange infrastructure and market makers so JPGC has reliable pricing and 24/7 tradability from the moment it lists.

NFT-Backed Redemption Mechanics

Designing JPG-NFT certificates that cryptographically represent entitlement to future physical gold redemption, with no ambiguity, duplication, or double-claims possible.

Regulatory Compliance Across Jurisdictions

Aligning with Nigerian SEC and EFCC oversight from day one, while architecting the platform to pursue international regulatory standards as it expands globally.

The Process

How we engineered a gold-backed token from reserve to exchange.

Six structured phases took JPGC from tokenomics design to a live, exchange-listed asset, each stage building on the last with zero shortcuts in security or compliance.

Discovery & Tokenomics Design

Modelled the 1:1 gold-backing ratio, supply mechanics, and redemption rules against Japaul's audited gold reserves and mining leases.

Smart Contract & SPL Token Architecture

Built the SPL token standard implementation on Solana, alongside Solidity contracts for EVM-side bridge compatibility.

Cross-Chain Bridge Integration

Integrated Wormhole to move JPGC across chains, unlocking multi-exchange listing without splitting liquidity.

JPG-NFT Certificate Development

Designed and minted NFT certificates on Solana representing verifiable entitlement to future gold redemption and in-game mining rights.

Platform & Exchange API Integration

Built the NestJS backend powering swaps, wallet connections, and exchange data feeds behind the JPGold Coin and JPGold NFT dashboards.

Security Audit, Testing & Launch

External smart contract security audits by Beosin, penetration testing, and a phased rollout ahead of listing on BitMart and major tracking platforms.

Enhancing Experience

World-class token and NFT engineering.

JPGC isn't a website or an app, it's a living financial instrument. That changes what "design" means: every decision, from tokenomics to contract architecture, has to hold up under real money and real scrutiny, on-chain, forever.

SmartTech Solutions brings the same rigour to every crypto engagement, whether it's a Solana SPL token, an EVM smart contract, or an NFT collection on a chain we haven't touched yet. We build tokens and NFTs for any blockchain, calibrated for real trading, real holders, and real regulatory scrutiny.

Multi-Chain Token Engineering
SmartTech Solutions designs and deploys tokens across Solana, Ethereum, BNB Chain, and any EVM or non-EVM network, tailored to each project's liquidity and community.
Audit-Ready Smart Contract Design
Every contract we ship is built with security-first patterns and independent audit trails baked in from day one, not bolted on after launch.
NFT Systems for Any Blockchain
From generative art drops to utility-backed certificates like JPG-NFT, we mint and verify on whichever chain fits the use case, Solana, Ethereum, BNB, or beyond.
Exchange-Ready Launch Engineering
Tokenomics, liquidity pooling, and exchange listing integration engineered for real trading volume from day one, not just a whitepaper promise.

Solution & Results

A gold-backed token, live and trading on global exchange like BitMart.

SmartTech Solutions architected, designed, and shipped the complete JPGold Coin ecosystem, from the SPL token and cross-chain bridge to the JPG-NFT certificate system and exchange-facing platform.

The result is a serious, production-grade digital asset that gives physical gold the liquidity, accessibility, and programmability of a native crypto token, without asking holders to give up what backs it.
