Security at monica.cash: How We Protect the Off Ramp Window

Crypto in, swept to settlement, naira out. Monica is a one-way off ramp, not a wallet. You do not have a crypto balance "at Monica" the way you would at an exchange or custodial wallet. When you send crypto to your Monica deposit address, the asset is being sold to Monica at the live mid-market rate. On confirmation, title transfers to Monica's treasury and Monica owes you the corresponding naira, which is paid out to your verified Nigerian bank account within 60 seconds of the network confirming. Monica does not hold your crypto after conversion, so there is no user crypto balance to lose if your phone, password or app is compromised.

The narrow operational window that does require active protection is the time between a blockchain deposit confirming and naira settling in your bank, within 60 seconds of the network confirming. During that window the relevant assets are Monica's own treasury crypto and the naira rail. Monica's treasury is managed under standard fintech operational-security practice; the naira side runs through NIBSS instant transfer, the same rails every Nigerian bank uses.

Naira withdrawals require app-side authentication (biometric or PIN) plus device-binding. Suspicious patterns trigger additional verification before the NIBSS instruction is sent.

Continuous transaction monitoring on both the incoming crypto side and the outgoing naira side. Velocity rules, address-blacklist matching against OFAC and Chainalysis feeds, and behavioural anomaly detection.

Careful data handling. KYC documents are stored encrypted with restricted internal access. No third party sharing without your explicit consent or a legal requirement (a court order, or a regulator or law enforcement directive).

Strong unique app password. Authenticator-app 2FA. Bookmark monica.cash. Never share seed phrases (Monica never asks; Monica is not a wallet and has no seed phrase to give you). Never click 'support' links from random sources.

No platform-side compromise to date, as of October 2026. Monica has operated since 2023.
