Our verdict

Relai is a French app for people who want to hold only bitcoin, buy with euros and keep custody of their own coins. The price of €0 and a taker fee of 1% keep running costs low, while 1 listed and self-custody make it a narrow choice.

Who it suits

  • Euro clients who want to hold bitcoin only, not a wide coin list
  • First-time buyers who want self-custody, and the app price is €0
  • Users who fund an app by card, bank transfer or SEPA, the methods listed under card, bank and sepa

Who should look elsewhere

  • Traders who need many coins, where eToro lists from 150
  • People who want a phone line, as support covers email, help centre and community only
  • Banking customers wanting a wider asset range, where bunq charges a taker fee of 0.25% to 1.99%

Fees and currency costs

The app price is €0 and the taker fee on trades is 1%. Bitcoin network fees are paid by the client when selling, while Relai covers network fees on purchases, so the cost of moving coins out depends on the network rather than on the exchange. Against bunq at 0.25% to 1.99%, Relai sits low on trading charges.

Frequently asked questions

What does Relai charge to buy and sell bitcoin?+

The taker fee is 1% on trades, and the app itself costs €0. Bitcoin network fees are paid by the client when selling, while Relai covers network fees on purchases. For comparison, bunq charges a taker fee of 0.25% to 1.99%.

Who holds my bitcoin?+

Custody is self custody, so the coins are held by you rather than by the exchange. Backups use a seed phrase, which means losing that phrase means losing access. This is the main safety trade-off to weigh.

How do I add euros to the app?+

Fiat deposits run through the methods listed at card, bank and sepa, covering card, bank transfer and SEPA. Because the entity is French and registered with the Autorite des Marches Financiers (AMF), euro funding is the natural fit for this app.

Which coins can I hold on Relai?+

The listing shows 1 coin, with the same single-coin scope reported for coins supported. That is very narrow next to eToro, which lists from 150 coins, so anyone wanting altcoins needs a different exchange.

Is Relai regulated?+

The licences list the Autorite des Marches Financiers (AMF) in France, a VQF (SRO member) registration in Switzerland, and a further AMF entry. The French licence ids are A2025-006 and MiCA CASP 9695003EKRFOMYXJQL11.

What kind of app is it?+

It is a mobile wallet from a centralised exchange setup, and it was founded in 2020. The operating company is RELAI EU SASU, based in France, so the product is built for euro and European clients.

How do I get help?+

Support runs on email, help centre and community, so you can email, use the help centre or reach the community. There is no phone line listed, which matters if you want to talk someone through a stuck withdrawal.

Is there a minimum or account fee?+

The price of the app is €0, and no other account charge is listed. The taker fee of 1% is the main ongoing cost, plus any bitcoin network fee when you sell.
