How to Deposit via SPEI Bank Transfer

Funding your Peanut account from a Mexican bank account is fast with SPEI. You send pesos from your bank to a CLABE that Peanut generates for you, and your balance updates as soon as Banco de México confirms the transfer — usually within seconds. Peanut charges no deposit fee, there are no business-day restrictions, and you can send any amount from about 50 MXN upward.

SPEI (Sistema de Pagos Electrónicos Interbancarios) is operated by Banxico and is the backbone of Mexican electronic payments. Every regulated Mexican bank and authorised fintech — BBVA, Santander, Banorte, Citibanamex, HSBC, Scotiabank, Nu México, Klar, Hey Banco, Albo, and more — settles transfers through it. Once your deposit lands, your balance is held in digital dollars. From there you can pay in Argentina with Mercado Pago QR, send Pix in Brazil, transfer money to friends and family, or withdraw to any Mexican CLABE via SPEI again.

Before You Start

Make sure you have the following before initiating your deposit:

• A verified Peanut account. Bank deposits require identity verification — a photo ID (passport or national ID card) plus a selfie. Most users complete it in under 2 minutes. No CURP or RFC is required. See the verification guide for details.

• A Mexican bank or fintech account. Any institution that participates in SPEI works: retail banks (BBVA, Santander, Banorte, Citibanamex, HSBC, Scotiabank), and digital banks and fintechs (Nu México, Klar, Hey Banco, Albo).

• Mexican pesos (MXN). SPEI only processes peso transfers. The minimum onramp through Peanut is about 50 MXN (roughly $3 USD equivalent).

How to Deposit via SPEI

1. 1

   Open the Peanut app

   Tap "Deposit" from your home screen to reach the deposit options.

2. 2

   Select bank transfer (SPEI)

   Choose the SPEI bank transfer option. The app will display the SPEI details for your deposit: a unique CLABE, the beneficiary name (STP or your assigned beneficiary), and a unique numeric reference tied to your account.

3. 3

   Copy the CLABE and reference number

   The reference number is what matches the incoming transfer to your Peanut account. Copy both the 18-digit CLABE and the reference exactly as shown — do not retype them manually.

4. 4

   Log into your bank or fintech

   Open your banking app and start a new SPEI transfer to a different bank.

5. 5

   Enter the payment details

   Paste the 18-digit CLABE. Enter the amount in MXN. Paste the numeric reference into the reference field, and add a short note in the "concepto" if your bank requires one.

6. 6

   Confirm and send

   Double-check the CLABE and the reference number before confirming. Once you send, Banxico settles in seconds.

Your Peanut balance updates automatically once Banxico confirms settlement. No action needed on your end after sending.

Confirmation Times

• Typical: under 30 seconds. SPEI is a real-time gross settlement system. Banxico's scheme target is end-to-end settlement in under 30 seconds, and the median is well below that.

• Up to a few minutes during peak load. During exceptionally busy periods (paydays, Buen Fin, large weekend events) some banks may queue transfers briefly. They still settle within minutes.

• 24/7/365 — no business-day restrictions. SPEI runs continuously, including weekends and Mexican public holidays. There is no batching, no next-day queue, and no "send before 4 PM" cut-off.

• Weekend high-value transfers. SPEI itself never closes, but a small number of sending banks pause very large weekend transfers for manual review. This is rare for typical deposit amounts.

If your deposit has not appeared after a few minutes, check the deposit troubleshooting guide for next steps.

Fees

• Peanut deposit fee: free. Peanut charges nothing to receive a SPEI transfer.

• Your bank's fee: typically MXN 0–11. Digital banks and fintechs (Nu México, Klar, Hey Banco, Albo) are almost universally free. Retail banks (BBVA, Santander, Banorte, Citibanamex) are usually free for personal transfers up to a daily limit; some charge 5–11 MXN per outbound transfer above that tier.

• Currency conversion to digital dollars. Peanut converts your incoming pesos to digital dollars at the Bridge MXN→USDC rate. The cross-currency conversion carries Bridge's 50bps FX leg plus Peanut's 50bps developer fee — about 100bps total, embedded in the displayed rate. There is no separate Peanut fee line.

Tips for a Smooth Deposit

Getting your deposit right the first time saves time. Here are the most common things to watch for:

• Copy-paste the reference number. SPEI carries both a free-text concepto and a numeric reference. The numeric reference is what matches the transfer to your Peanut account — a missing or incorrect reference is the leading cause of held-up deposits. Always copy directly from the app.

• CLABE must be exactly 18 digits, no spaces. Mexican banking apps usually strip spaces automatically, but double-check before confirming. A wrong CLABE typically auto-returns within 1–5 business days.

• Name on your bank account must match Peanut. The sender name on the SPEI transfer must match the name on your verified Peanut account. Sending from a joint or business account with a different name may trigger a manual review.

• Send in MXN only. SPEI is a peso rail. If you hold USD or USDC in a Mexican account, convert to MXN before initiating the SPEI.

• Mind your bank's daily SPEI limits. Many retail banks default to per-day caps of MXN 50,000–200,000 for individuals. You can usually raise the cap in the app or by calling customer service. Peanut has no hard limit; transfers totalling above $100,000 USD equivalent may trigger Bridge's standard manual compliance review.
