With a stablecoin you pay exactly the amount the invoice states. While Bitcoin can move several percent inside the 15-minute price-lock window, a dollar-pegged token stays essentially flat. That makes stablecoins the most precise way to pay for precious metals with crypto.
Every purchase with cryptocurrency stacks two prices on top of each other: the metal price in euros, and the rate of your currency. We lock both for 15 minutes. With Bitcoin, something can genuinely move in that time — which may work for or against you, but is an open position either way.
A stablecoin takes that uncertainty out. The amount leaving your wallet matches the invoice amount; an over- or underpayment caused by price movement effectively cannot happen.
The established option with the widest reach. Over TRC-20 (Tron) a transaction costs less than a euro and confirms in one to three minutes. Send USDT on Ethereum mainnet and you pay many times that in gas fees, depending on load.
Fully backed by cash and short-dated government bonds, with monthly attestations. Over Solana or Base, transactions are effectively free and final within seconds — the most efficient route for amounts under a thousand euros.
DAI is not issued by a company but backed by over-collateralised crypto positions in smart contracts. If you want no central issuer on principle, this is the most consistent option — technically more demanding, and more expensive on mainnet.
USDT on Tron and USDT on Ethereum are not the same thing. Send to a network the receiving address does not know and the payment can be lost. So always check two things before you send: the address and the chain.
At our checkout the chain sits in large type above the address, and we show the expected number of confirmations. If your wallet offers several networks for the same currency, pick exactly the one displayed.
A tip for your first purchase: send a small test amount if you have not used a chain before. Fees on TRC-20 or Solana are so low that a test transfer costs almost nothing.
Stability does not mean freedom from risk. A dollar-pegged token carries currency risk against the euro — if the dollar falls, the euro value of your holding falls with it, even though the token still trades at one dollar.
On top of that comes issuer risk: with USDT and USDC, the peg depends on the reserve and on the issuer's willingness to redeem at any time. Both providers can also freeze addresses. For the moment of a payment that hardly matters; for holding over the long term it does.
Yes. MetalReserve accepts USDT on TRC-20, ERC-20, Solana and BEP-20. The cheapest is TRC-20, with a network fee under one euro and confirmation in one to three minutes.
USDC over Solana or Base has network fees under five cents and is final within seconds. USDT over TRC-20 costs about €0.80. Ethereum mainnet is the most expensive option for every stablecoin.
Because they barely move inside the price-lock window. The amount you send therefore matches the invoice amount very closely — unlike volatile currencies, where an over- or underpayment can arise.
The payment does not reach us and can be lost. Always check the chain shown at checkout before sending. If you are unsure, send a small test amount first.
Figures for fees and confirmation times are typical values as at July 2026 and vary with network load. Not investment advice.
