Our verdict

Relai is a French app for euro buyers who want bitcoin in self-custody, with an AMF licence and a free mobile wallet. The trade-off is scope: fees of 1% and a coin list of 1 make it a focused single-asset home rather than a full exchange.

  • Network fees are covered on purchases, and sellers pay only the bitcoin network fee.

Cons

Scored 8.7 / 10 by HodlCue.

Who it suits

  • Euro buyers in France who want their own keys, with self custody and a seed backup.
  • Holders who keep a single asset rather than a trading book, since the coin list is 1.
  • People who fund with card, bank and sepa and want a free wallet at €0.

Who should look elsewhere

  • Altcoin traders: Bitpanda lists from 650 coins, Relai lists 1.
  • Buyers who chase the lowest fee: bunq charges 0.25% to 1.99% against Relai's 1%.
  • Traders who want cheap execution: ActivTrades charges 0%.

Frequently asked questions

What does Relai charge to buy and sell bitcoin?+

The wallet and buying or selling through it cost €0, and the listed taker fee is 1%. Network fees are covered on purchases, while sellers pay the bitcoin network fee. Small recurring buys stay cheap, though larger trades still carry the taker fee.

Which coins can I hold and buy?+

Relai covers bitcoin and nothing else: the coin list is 1 and the wallet supports 1. There is no altcoin trading here, so anyone holding many assets needs another venue. That focus keeps the app simple for a single holding.

Who holds my bitcoin?+

Keys stay with the holder: custody is self custody and self-custody is listed as a feature, with a seed backup for recovery. A lost recovery phrase cannot be restored by the platform, so write it down and keep it offline.

Is Relai regulated?+

The French operation is registered with the Autorite des Marches Financiers under A2025-006, and the MiCA listing records MiCA CASP 9695003EKRFOMYXJQL11. The group also appears with a VQF registration in Switzerland, so the licence sits with the company rather than the app.

How do I fund the account?+

Fiat arrives through card, bank and sepa, so a French customer has several ways to top up rather than a single route. Relai operates as a cex under RELAI EU SASU in France, so buying works as a standard account top-up rather than a peer transfer.

How do I get help?+

Support runs through email, help centre and community, so a help centre, email and a community are the routes in. There is no phone line listed, which matters for anyone treating this as a trading desk rather than a self-custody app.

What kind of wallet and app is it?+

The wallet is a mobile app rather than a hardware device, which suits buying in small amounts from a phone. Relai was founded in 2020 in France and now runs a regulated operation under RELAI EU SASU.

Is Relai right for me?+

Relai suits euro buyers who want their own keys and a free wallet rather than a broad exchange. It is a poor fit for altcoin traders, since the coin list is 1, and for fee-first buyers, since fees of 1% sit above the site taker fee of 0.2%.
