About S3lf
Your money. Only yours.
S3lf is a self-custody account for holding, moving and investing — reais,
dollars and real-world assets in one place.
Most financial apps hold your money for you. S3lf doesn't. Your account is
created on your device and secured by a recovery phrase that only you have.
We can't freeze it, hold it, or move it — not because of a policy, but
because of how the app is built.
ONE ACCOUNT, THREE THINGS
Hold — Keep balances in reais and dollars in a single account.
Move — Send and receive at any hour. No business hours, no waiting for the
next working day.
Invest — Access tokenized real-world assets. What you buy is registered to
your own wallet, not held for you by an intermediary.
WHAT'S INSIDE
- Self-custody wallet — your recovery phrase is generated on your device and
never leaves it
- Buy and sell tokenized assets, with a full breakdown of every fee before
you confirm
- Price charts and asset details, so you can see what you're buying
- Full transaction history with downloadable receipts
- Identity verification built in, so you're ready to invest
- Available in English and Portuguese
HOW IT WORKS
1. Create your account — it takes seconds
2. Write down your recovery phrase and keep it safe
3. Add funds
4. Invest when you're ready
Your recovery phrase is the only way to restore your account. Write it down
and store it offline. We cannot recover it for you — that's what self-custody
means, and it's the point.
THE DOOR STAYS OPEN
Leave whenever you want, and take everything with you. Your assets live on a
public blockchain, and your recovery phrase works anywhere. No lock-in.
s3lf is a service by IWSC DAO LLC.
Cryptoassets and tokenized assets are volatile and carry risk, including the
risk of losing the amount you invest. S3lf does not provide investment advice.
Availability of features varies by country.
