Every December, the diaspora flies home with an envelope. This year, leave it in the drawer.
If you are an IJGB coming home to Lagos this December, here is the short answer to the dollar question. You do not need to change a pile of cash at all. Hold your dollars as USDT or USDC on Mular, and pay any Nigerian bank account in Naira straight from that balance: the person on the other end gets Naira in about ten seconds, and it costs ₦50 per payment as at 5 Nov 2026. Change only a little cash for the odd moment that needs it. The rest of this guide is the detail: your options, the costs, the cash rules, and where the old way still wins.
What Is an IJGB, and Why Is Changing Dollars Such a Wahala?
IJGB stands for "I Just Got Back", the half-teasing name Lagos gives everyone who flies in from London, Houston or Toronto for the Christmas season, usually still in the jacket they wore at Heathrow. The hard part starts at arrivals, when you realise the city runs on Naira, your money is in dollars, and everyone offering to bridge that gap has a slightly different number in mind.
And it is the same envelope every year: crisp hundred dollar bills, counted twice in the departure lounge and patted every ten minutes on the plane. By day two the envelope has become a job: finding someone to change it, haggling over the rate, and counting a brick of Naira notes on a car bonnet.
Your Options for Turning Dollars Into Naira in Lagos
There are really four ways people do it, and I am not going to pretend any of them is useless. Each has its moment.
The first is cash at a bureau de change, or the man on the corner who works with one. It is fast and everywhere, and the rate is whatever the conversation decides, which is the problem. The second is your foreign card at a POS or ATM, which works until your home bank decides a Lagos transaction looks suspicious at 1am and freezes the card, or until the foreign transaction fees show up on your January statement.
The third is a remittance app into a Nigerian account, fine if you already have one. The fourth is the one this post is about: hold your dollars as a stablecoin (USDT or USDC, digital dollars that track the US Dollar one to one) and pay people in Naira straight from that balance. No envelope, no corner, no counting.
How Much Cash Can You Bring Into Nigeria?
If you do bring cash, know the line. Anyone arriving in Nigeria with more than $10,000 in cash, or its equivalent in other currencies, has to declare it to Customs on arrival.* Carrying the money is not the offence; failing to declare it is, and undeclared cash can be seized. Airlines now remind inbound passengers before landing, so nobody gets to say they did not hear it, and most people coming home for a few weeks will never get near that number anyway.
How to Pay in Naira Straight From Your Dollars on Mular
- Before you fly, download Mular and fund your USDT or USDC wallet from the exchange or app where your dollars already sit. Funding a stablecoin wallet on Mular is free.
- When it is time to pay (the shortlet host, the tailor, the driver, the restaurant), ask for their bank name and account number. In Lagos everyone has one ready.
- On Mular, tap Send, choose the bank and enter the account number, then type the amount in Naira and check the account name that comes up.
- Confirm from your USDT or USDC balance. The Naira lands in their account in about ten seconds, and you show them the "successful" screen.
If you would rather hold some Naira for the week, send to your own Naira wallet on Mular instead and spend from there. The conversion fee for that is free, and the money never has to leave the app to be useful.
What It Costs, How Fast It Is, and the Rate You Get
Paying a bank account from a stablecoin balance costs a flat ₦50, as at 5 Nov 2026, whether it is a plate of suya or a week at a shortlet. It arrives in about ten seconds, which is roughly how long it takes a BDC man to say "the rate has changed since morning". The rate itself moves through the day, so check the live Dollar to Naira or USDT to Naira page before a big payment.
Now, the boring bit: keep track of what you spend, because by the 28th of December nobody remembers what the boat trip cost, and January you will want to know. Although, almost forgot: Mular keeps every payment in your history already, with the date, the amount and who received it. No notebook required.
Is It Safe to Pay This Way?
On the receiving end it is a normal bank transfer, so the usual Lagos rules apply. Check the account name before you confirm, and never pay into an account that does not match the business or person you are dealing with. What this method removes is the hand-to-hand moment, where somebody counts your money faster than you can. For the rest, we have written up the scams that target IJGBs every December.
When Cash Still Makes Sense
I will not oversell it. The okada man at the end of a long night may still want notes, a few market stalls prefer them, and some hotels insist on a card for the deposit. So change a little, enough for a few days of small moments, after checking the converter so you know what a fair number looks like. Just do not build the trip around the envelope.
The Envelope Was Always the Expensive Part
The smart way to convert dollars to Naira is to stop thinking of it as a separate errand. Every lump of cash you change costs you the rate, the risk and an afternoon,. Pay as you go, from the dollars you already hold, and the conversion happens at the moment you need it and not a minute before. The envelope can stay in the drawer back home, with the winter gloves.
Your Dollars, Spent as Naira, Without the BDC
Mular lets you hold your money as USDT or USDC and pay any Nigerian bank account in Naira straight from that balance, with the money landing in about ten seconds for a flat ₦50.
Download Mular before you board, and land with nothing to change.
As always, stay Jiggy.
Love, Mr Mular.

Last year's version was a three-day club itinerary. This one answers the question every IJGB actually asks at arrivals.
