Our verdict
Rainbow is a mobile, self-custody crypto wallet, and it suits people who want their keys held on their own phone. The median wallet price across wallets on SumCue is €0, and pairing mobile access with self custody is what sets it apart from the custodial platforms.

Pros and cons
Pros
- Mobile by design (mobile), so the wallet lives on a phone
- Self-custody (self custody) leaves control of the wallet with its user
- Seed backup (seed), the route behind 85% of the wallets on SumCue
- Support runs on email, help centre and community, covering email, a help centre and a community
Cons
- Hardware is not among its wallet types (mobile), so anyone wanting a dedicated device should look at Trezor
- Self-custody (self custody) puts the keys and the backup squarely with the user, so no provider can restore access
- Recovery rests on a seed (seed), so the wallet is only as safe as where the recovery phrase is kept
Ready to try Rainbow?
Who it suits
- People who want a wallet on a phone and hold the keys themselves (mobile with self custody)
- Users comfortable writing down and guarding a seed backup (seed)
- Readers who are happy with written help, since email, help centre and community covers email, a help centre and a community
Who should look elsewhere
- Anyone set on a hardware device: Trezor is hardware, which is not Rainbow's mobile
- People who want a provider to hold the keys, where eToro (custodial) and Bitpanda (custodial) take on custody
The company behind it
Rainbow is run by Rainbow Studio, Inc. and is headquartered in the United States, which makes its terms of use the document that governs anyone opening the app from the UK or Europe. Support runs on email, help centre and community: email, a help centre and a community forum. Help is written rather than spoken, and the community channel puts users in touch with other wallet holders for practical questions.
How Rainbow compares
Frequently asked questions
What type of wallet is Rainbow?+
Rainbow is a mobile wallet (mobile), so it runs on a phone rather than a desktop or a separate device. Keys stay with the user under a self-custody model (self custody). That pairing suits people who want everyday access to their own keys without buying hardware to hold them.
Does Rainbow hold my coins for me?+
Rainbow uses self-custody (self custody), so the wallet user keeps the keys. eToro (custodial) and Bitpanda (custodial) run on custodial custody, where the provider holds them instead. The trade-off is control against convenience, and with self-custody the recovery of a lost wallet rests entirely with the owner.
How is a Rainbow wallet backed up?+
Backups run on a seed (seed). That recovery phrase is what restores a Rainbow wallet, so it needs writing down, storing somewhere safe and never sharing. Recovery depends on holding both the phrase and access to the app, so the two should be kept apart.
What support does Rainbow offer?+
Support runs on email, help centre and community, which covers email, a help centre and a community. Answers are written, with peer help sitting alongside the company's own, which suits readers who are comfortable setting out a problem in writing and searching for a fix. Recovery questions usually start in the help centre.
Who runs Rainbow and where?+
Rainbow is run by Rainbow Studio, Inc., a company headquartered in the United States. Its terms of use govern the app for anyone opening it from the UK or Europe and set out what happens to keys and backups. With self-custody in place, the user is the one who has to act on them.
How does Rainbow compare with Trezor?+
Trezor is a hardware wallet (hardware), which keeps keys on a dedicated device. Rainbow is a mobile wallet (mobile) that lives on a phone. Hardware suits coins put away for the long term, while a phone suits frequent transactions and payments on the move, and plenty of people hold both.
What do wallets cost on SumCue?+
Wallet prices across SumCue sit at a median of €0, with hardware models near €0 at the top of the range. Rainbow sits at the free end as a mobile app, so the running cost for the user is the attention behind the seed backup rather than a subscription.
