Fiat to Precious Metals

Convert eUSD/eEUR/eGBP to eGOLD, eSilver, and ePlatinum with instant settlement and verifiable reserve backing. Bridge fiat currencies to commodity-backed digital assets.

What You Get

A complete fiat-to-commodity bridge with instant conversion and verifiable metal backing.

Instant Conversion

Convert fiat stablecoins (eUSD/eEUR/eGBP) to commodity stablecoins (eGOLD/eSilver/ePlatinum) in seconds.

Verifiable Reserves

All commodity stablecoins backed by physical precious metals in secure vaults with regular audits.

Multi-Asset Support

Support for gold, silver, platinum, and other precious metals with instant liquidity.

FX Infrastructure

Built-in FX via reForge for seamless multi-currency to metal conversions.

Implementation Steps

Seven steps to enable fiat-to-metals conversion infrastructure.

1
Configure Fiat Stablecoins

Enable eUSD, eEUR, and eGBP as source currencies for metal conversions. Set up user wallets and balances.

// Initialize fiat stablecoins
const currencies = ['eUSD', 'eEUR', 'eGBP'];
for (const currency of currencies) {
  await stablecoins.configs.enable({
    asset: currency,
    userId: user.id,
    autoMint: true
  });
}
2
Enable Commodity Stablecoins

Configure eGOLD, eSilver, and ePlatinum with vault backing and redemption rules.

// Enable commodity stablecoins
const commodities = [
  { asset: 'eGOLD', backing: 'gold_vault_lbma' },
  { asset: 'eSilver', backing: 'silver_vault_lbma' },
  { asset: 'ePlatinum', backing: 'platinum_vault_lbma' }
];

for (const commodity of commodities) {
  await stablecoins.configs.enable(commodity);
}
3
Set Up FX Infrastructure

Integrate reForge for currency conversion and commodity pricing. Enable multi-currency to metal flows.

// Convert EUR to Gold
const conversion = await reForge.convert({
  from: 'eEUR',
  to: 'eGOLD',
  amount: 1000, // 10 EUR
  slippageTolerance: 0.005 // 0.5%
});

console.log({
  rate: conversion.rate, // EUR per gram of gold
  goldReceived: conversion.amountReceived,
  fee: conversion.fee
});
4
Implement Instant Conversion

Build user-facing conversion interface with real-time rates and instant settlement.

  • Real-time metal pricing from markets
  • Instant fiat → metal conversion
  • Transparent fee structure
5
Add Reserve Verification

Implement real-time reserve verification and display vault audits to users.

// Verify metal reserves
const reserves = await stablecoins.reserves.verify({
  asset: 'eGOLD'
});

console.log({
  totalSupply: reserves.totalSupply,
  vaultBalance: reserves.vaultBalance,
  backingRatio: reserves.backingRatio, // Should be 1.0
  lastAudit: reserves.lastAuditDate,
  auditReport: reserves.auditReportUrl
});
6
Test Metal Backing

Comprehensive testing of conversion flows and reserve verification in sandbox.

  • Test eUSD → eGOLD conversion
  • Test eEUR → eSilver conversion
  • Verify reserve backing ratios
  • Test redemption flows (metal → fiat)
7
Launch

Go live with fiat-to-metals conversion. Enable users to hold precious metals digitally.

  • Launch conversion interface
  • Publish reserve audit reports
  • Enable physical redemption (optional)
