Buy and sell crypto directly inside Bron using fiat currency (USD or EUR). Purchases and sales are powered by Noah β their terms apply. Bron does not process, settle, or guarantee transactions.
To use Buy/Sell, you must first complete identity verification (KYC).
1. How Money Moves β Buy and Sell
Three parties are involved in every Buy or Sell: you, Bron, and Noah (the fiat on/off-ramp). Here's exactly who does what.
1.1 Buy cryptocurrency: USD or EUR β USDC
You initiate Buy in Bron and choose the USDC amount.
Bron shows you a Virtual Account (an IBAN) β issued by Noah, in your name, dedicated to this purchase.
You send the fiat from your own bank account to that Virtual Account.
Noah receives the fiat and converts it to USDC at the rate you saw in the Preview.
Noah delivers USDC into your Bron account.
π‘ You don't add your bank account in Bron for buying. The wire goes from your bank straight to the Virtual Account.
π‘ Want a different token? Hold USDC after the Buy, then use Swap inside Bron to convert it to ETH, BTC, SOL, etc.
1.2 Sell cryptocurrency: USDC β USD or EUR
You add the destination bank account to the Bron Address Book β either your own bank account, or a counterparty you owe (settling an invoice).
You initiate Sell in Bron β choose the USDC amount and pick the bank account from your Address Book.
Bron sends USDC to Noah at the deposit address.
Noah converts USDC into USD/EUR, and the wire goes through your virtual IBAN to the destination bank. If it's your own account, it shows up on your bank statement as an own funds transfer.
Noah wires the fiat to the destination bank.
π‘ Holding ETH, BTC, or USDT? Swap to USDC inside Bron first, then sell.
2. How to Access Buy/Sell
The Buy/Sell button is located on the right-hand sidebar of the Bron app.
Tap Buy/Sell to open the panel. You'll see two tabs at the top: Buy and Sell.
3. Verification & KYC (Required for Fiat Transactions)
Before you can buy or sell crypto with fiat, you need to complete identity verification.
KYC is handled by SumSub β Bron's identity verification provider for fiat transactions. You'll be securely redirected to their website to complete the process.
π‘ KYC is only required for fiat transactions. You can hold, swap, and send crypto on Bron without completing verification. KYC is only needed when buying or selling crypto with fiat.
3.1 Individual or Business
Both individuals and businesses can complete verification.
Individual β standard personal KYC. Retail limits apply (see Buying Limits).
Business (KYB) β verification for legal entities. The process and required documents differ from the individual flow β Noah may ask for incorporation documents, beneficial owner info, and business address. Retail limits are not shown in the app; business limits are agreed with Noah directly.
You can complete both an individual and a business verification on the same profile β they are independent submissions.
3.2 Verification is active in one workspace at a time
Your KYC documents are submitted to Noah once β you don't have to upload them again later. But Buy/Sell itself is active in only one of your workspaces at a time.
When you complete verification, it links to the workspace where you started. In any other workspace you'll see "Verification is linked to another workspace" with a button to switch to the verified one.
π‘ Need to move verification to a different workspace, or switch between personal and business? Open Buy/Sell β Verification details, tap the menu (β’β’β’), and choose Unlink verification. Then re-verify (or re-use your existing documents) in the workspace you need. Documents stay on file with Noah β you don't repeat the upload.
π‘ One user in one workspace can be verified as either a business or an individual.
4. Buying Limits
For individual verifications, limits are set per asset and calculated separately:
Currency | Single transaction | Monthly limit |
USD | $10,000.00 | $20,000.00 |
EUR | β¬15,000.00 | β¬30,000.00 |
Limits are calculated on a rolling 30-day basis. Once you reach your limit, you'll need to wait or upgrade your verification level.
To increase your limits, tap Increase on the Verification and limits screen and complete a higher level of verification.
β οΈ Noah may request additional documents when you increase your limits β such as proof of address or income statements. This is a standard compliance requirement and is handled by Noah directly.
For business verifications, retail limits are not shown in the app β your limit is agreed with Noah directly as part of onboarding.
5. How to Buy Crypto
Open Buy/Sell from the right sidebar.
Select the Buy tab.
Under Account, select the Bron account that will receive the USDC.
Under Pay with, select the fiat currency (USD or EUR).
Enter the amount and tap Set amount.
Tap Preview to see Noah's rate, the Bron platform fee, and the total.
Confirm. Bron shows you a Virtual Account (IBAN) issued by Noah in your name β that's where you wire the fiat from your own bank.
π‘ Make sure to select the correct account before confirming. This determines which Bron account will receive the purchased USDC.
6. How to Sell Crypto
Before you can sell, you need a bank account saved in your Address Book β that's where Noah will wire the fiat. The destination can be your own account or a counterparty you owe. See Bank Account in Your Address Book below if you haven't added one yet.
Open Buy/Sell from the right sidebar.
Select the Sell tab.
Under Account, select the Bron account holding the USDC you want to sell.
Choose USDC and enter the amount.
Under Receive to, pick a bank account from your Address Book (or tap Add bank account to create a new one).
Tap Preview to see Noah's rate, the Bron platform fee, the wire-rail fee, and the net amount that will arrive in the destination bank.
Confirm. Bron sends USDC to Noah; Noah converts and wires the fiat.
π‘ Holding ETH, BTC, or USDT? Use Swap inside Bron to convert to USDC first, then come back here to sell.
π‘ The fiat doesn't arrive instantly β once you confirm, the wire travels through the banking network. SWIFT typically takes 1β3 business days, SEPA up to 1 day, ACH 1β3 business days, Fedwire same day.
7. Bank Account in Your Address Book
Your bank account is the destination Noah uses to send you fiat when you Sell. It's stored as a record in your Address Book β separate from crypto addresses and Bron Tags.
Your Noah Virtual Account is a full-fledged bank account under the hood, so the destination can be either of two things:
Your own bank account β Sell to yourself, settle to your personal or company account.
A counterparty's bank account β pay an invoice from a service provider (private aviation, yacht charter, school fees, a vendor, etc.). See Paying a counterparty's invoice below.
β οΈ This is not a peer-to-peer rail. Sending fiat to a friend's or family member's account, gifts, or any personal P2P transfer is not supported by Noah and will be blocked at compliance review.
7.1 Supported payment channels
Noah supports four wire channels β the one you pick determines where the destination bank sits and what details you need to enter:
Channel | Use for | Required fields |
SEPA | EUR, EU/EEA banks | Account holder name, IBAN, BIC/SWIFT (auto-derived from IBAN in many cases) |
SWIFT | International USD or EUR wires | Account holder name, account number, BIC/SWIFT code, bank name and address, country |
ACH | US domestic, slower and cheaper | Account holder name, account number, routing number (ABA), bank name, account type (checking/savings) |
Fedwire | US domestic wire, same-day | Account holder name, account number, routing number (ABA), bank name and address, payment purpose |
7.2 How to add a bank account
Go to Workspace settings β Address Book, or open Buy/Sell β Sell tab β Receive to β Add bank account.
Choose Bank account as the record type.
Pick the country and fiat currency β this determines the channels Noah offers.
Pick a channel (SEPA / SWIFT / ACH / Fedwire).
Enter the bank details required for that channel (see the table above). For your own account use your name; for a counterparty use the holder name exactly as it appears on the invoice.
Give the record a display name β something only you see in your Address Book, e.g. "Chase USD" or "NetJets invoice account".
Confirm with 2FA.
π‘ You can save multiple bank accounts β your own across different currencies, and each counterparty you pay regularly. Each one can be reused for any Sell that matches its currency and channel.
7.3 Paying a counterparty's invoice (B2B payments)
Because the Virtual Account behind your Sell is a real bank account, Noah can wire fiat not only back to your own bank but also to a counterparty you owe. This is the route for settling B2B-style invoices β private flights, yacht charter, school fees, vendor invoices, consultancy, etc.
What this supports:
Settling an invoice issued to you or your company.
Paying a service provider against a contract or agreement.
Paying a vendor for goods.
What this is NOT:
Sending money to a friend or family member.
Gifts or peer-to-peer transfers.
Any payment without a clear commercial purpose.
The flow:
The counterparty issues you an invoice with standard SWIFT details β their account number / IBAN, the company name, bank name and address, BIC/SWIFT code.
You add the counterparty's bank account to your Address Book using those details.
You initiate Sell with that counterparty account as the recipient.
From Noah's perspective, this is a transfer from your named Virtual IBAN to a third party β a perfectly normal bank wire.
For payments of this kind, Noah's compliance team may email you directly requesting two things:
Purpose of payment β the contract or agreement under which the invoice was issued.
Source of funds β proof of where the money came from.
You upload the documents directly to Noah.
If the documents check out, Noah releases the payment to the counterparty. If they're rejected, Noah returns the fiat to your Virtual Account.
π‘ Keep the invoice and the underlying contract handy before initiating a counterparty payment, especially for larger amounts. Having them ready means Noah's compliance review takes hours rather than days.
β οΈ The Noah compliance email is the real channel for these document requests. If anyone asks you for invoice or source-of-funds documents through Bron's chat or by phone, that's not how this process works β contact support@bron.org first.
8. Supported Currencies
Fiat currencies for buying and selling:
USD (United States Dollar)
EUR (Euro)
Crypto: only USDC can be bought or sold directly with fiat. USDC is supported on Ethereum and Base networks.
To buy or sell other tokens (ETH, BTC, SOL, USDT, etc.), buy USDC first and then convert it into any crypto you need through a Swap function in Bron.
9. Fee Structure
When you Buy or Sell crypto with fiat, the total you pay is made up of three components. Bron's platform fee is one of them; the other two come from Noah and the banking network. This section breaks down each layer so you can see exactly what's being charged β and by whom.
Three components
Every Buy or Sell totals these components:
Bron platform fee β Bron's margin, scales with the amount.
Provider fee (Noah) β a small Noah percent + a fixed payment-rail fee for the channel used (SWIFT / Fedwire / ACH / SEPA).
Correspondent bank charges β for SWIFT routes only: intermediary banks between Noah and the destination can each deduct a small fee from the wire.
9.1 Platform fee β what Bron charges
This is the only fee Bron itself collects. It depends on your plan:
Plan | Platform fee |
Basic | 0.60% |
Pro | 0.30% |
Enterprise | 0.10% |
Founders Club | 0% |
You see the platform fee as its own line in the Preview before you confirm. It scales with the transfer amount β a percentage of the fiat amount.
9.2 Provider fee β what Noah charges
Noah is the fiat on/off-ramp. The Provider fee line in Preview bundles two things:
Noah's percent fee β Noah's own margin on the transfer amount. Bron negotiated a favourable rate, so this layer stays well below the platform fee and is dwarfed by the wire-network costs below. You'll see it folded into the Provider fee line β no separate breakdown.
Payment-rail fee β a fixed fee charged by the payment network. Depends on the rail Noah uses:
SWIFT (international USD wire): ~$30
Fedwire (US domestic USD wire): ~$18
ACH (US domestic, slower): ~$1
SEPA (EUR within the SEPA zone): ~β¬1
Both are shown together in the Preview as a single Provider fee line.
9.3 Correspondent bank charges (SWIFT only)
When fiat moves via SWIFT, the wire usually passes through one or more intermediary banks between Noah and the destination. Each intermediary can deduct a "lifting fee" β typically $10β$30 per intermediary. Transatlantic transfers usually go through 1β3 correspondents.
These charges are taken from the wire amount before it reaches the destination, and are not visible in the Preview.
β οΈ Correspondent bank fees are not Bron's or Noah's. They're charged by intermediary banks in the SWIFT network. We can't see them in advance, refund them, or contest them. If the wire arrives with less money than the Preview said, the gap is correspondent fees.
SEPA, ACH and Fedwire don't use correspondent banks, so this layer doesn't apply to them.
9.4 Putting it all together β realistic totals
For a USD Buy via SWIFT (typical international transfer):
You send | Bron 0%β0.60% | SWIFT rail | Correspondent | All-in cost (approx.) |
$10,000 | $0β$60 | $30 | $0β$60 | ~$30β$155 |
$100,000 | $0β$600 | $30 | $0β$60 | ~$30β$740 |
$1,000,000 | $0β$6,000 | $30 | $0β$60 | ~$30β$6,590 |
The Bron column shows a range across plans: lower bound is Founders Club (0%), upper bound is Basic (0.60%). Pro (0.30%) and Enterprise (0.10%) fall in between.
The all-in includes a small Noah percent fee on top of the columns shown. At every size, that Noah layer stays well under the platform fee.
Two things stand out:
On large transfers, the all-in cost approaches the platform fee. At $1,000,000 the fixed wire costs disappear β what remains is essentially your plan-tier fee (0% on Founders Club, up to 0.60% on Basic).
The fixed SWIFT rail fee (~$30) is constant regardless of amount, so on smaller transfers it dominates as a percentage. Use a domestic rail (ACH / Fedwire) or SEPA where possible.
9.5 Why even a small test transfer over SWIFT costs ~$30+
If you wire a small test amount β say $5 β to confirm the flow before sending a real transfer, the receipt looks alarming. A $5 USDC Sell via SWIFT breaks down like this:
Bron platform fee: pennies (a fraction of a cent on Founders Club, ~$0.03 on Basic)
Noah percent fee: a fraction of a cent β negligible at this size
SWIFT rail fee (fixed): $30
Optional correspondent bank fees: $0β$60
Total: $30β$90 on a $5 transfer. The percentages are negligible β the entire cost is the fixed banking network fees, which apply regardless of the amount sent. Neither Bron nor Noah keeps that $30 β it goes to the SWIFT network and the banks involved. If you want to verify the path, use SEPA (~β¬1) or ACH (~$1) for the test instead.
9.6 Tips to minimise fees
Avoid SWIFT for small transfers. A $30 fixed fee dominates anything under $1,000.
Use SEPA for EUR transfers within the EU. Often free or near-free, and arrives same day.
Use ACH or Fedwire for US-domestic transfers instead of SWIFT.
Batch transfers β sending $5,000 once is dramatically cheaper than five $1,000 transfers.
