Coinmerce is a Dutch fiat-to-crypto broker that was founded in 2017 in Amstelveen by Nick and Luc Smits van Oyen. The platform is designed as a simple buy, sell and swap interface aimed at Dutch and European retail users rather than active traders, and a smart-order system aggregates liquidity from a network of external exchanges to surface the best available price for each operation. The catalogue covers around 350 cryptocurrencies, with the focus on accessible execution rather than order-book depth, margin or derivatives products. Both a desktop web app at coinmerce.io and native iOS and Android applications expose the same feature set.

Trading fees are a flat 0.25% applied uniformly to buy, sell and swap operations across all supported assets, regardless of trade size. Coinmerce offers two account types: a Yield Account, which is free to use and includes an optional opt-in lending feature, and a Custody Account, which charges a 1 euro monthly subscription and an additional 1% annual custody fee deducted monthly on balances at or above 10,000 euros. Deposits are free through iDEAL (instant), with Sofort, SEPA bank transfer and bank card also supported, and withdrawals are charged at network cost only. The platform settles in euro and runs primarily in Dutch, English and German.

From a regulatory standpoint, Coinmerce B.V. was added to the De Nederlandsche Bank (DNB) crypto register on 5 November 2020 as the fourth Dutch crypto firm under Wwft anti-money-laundering supervision. On 6 November 2025 the AFM granted Coinmerce a Crypto-Asset Service Provider (CASP) licence under MiCAR, giving the company passporting rights across all 27 EU member states, with Germany and France named as the first expansion targets. The legal entity is Coinmerce B.V., trading as Coinmerce Group with Jaap de Bruijn as CEO. The corporate group also includes the sister brand Coinmerce Capital, which started as the asset manager Icoinic before being acquired in 2024 and rebranded, and which itself acquired BlockchainTraders in 2025. No security incidents or regulatory enforcement actions are on the public record against Coinmerce.
