Lumx vs UnblockPay

Which should you choose, Lumx or UnblockPay?

Choose Lumx if the account has to be in the customer's name and in the customer's currency. A marketplace paying Brazilian sellers needs a BRL account with agência and conta per seller; UnblockPay pays them over Pix from a per-payment instruction. A payroll platform in Mexico needs a CLABE per worker; UnblockPay's named accounts are USD and EUR. A lender in Colombia needs PSE and Bre-B; UnblockPay lists Colombia as coming soon. A US counterparty doing diligence will ask for a FinCEN registration; Lumx US OP LLC has one, and UnblockPay's site names no US entity. Lumx also adds Faster Payments in GBP, which UnblockPay does not mention.

Choose UnblockPay if you are the reseller, not the end customer. Its partner programme gives FX correspondents and investment offices a dashboard, a configurable spread applied at quote time and the client relationship, with UnblockPay handling banks, liquidity and compliance behind the brand. Its fiat-to-fiat endpoint chains an inbound rail, a stablecoin hold and an outbound rail into one quoted transaction, which Lumx does not expose as a single call. Its Argentine CVU rail is live where Lumx has ARS announced.

If your flow is Pix in Brazil or SPEI in Mexico from a stablecoin balance, both work, both custody per customer and both run Sumsub; the decision comes down to whether you need the named local account, the US registration and the extra corridors.

What is UnblockPay?

UnblockPay is the brand of UNBLOCK Sociedade Prestadora de Serviços de Ativos Virtuais Ltda., a Brazilian virtual asset service provider founded in 2025 by a team that previously built a banking-as-a-service fintech acquired by StoneCo (the company is not named on its site). It raised a $4.5M seed in March 2026 led by Prelude, with Plug and Play, Wintermute, Reverie, Signature Ventures, Triaxis Capital, Crescera Capital and angels from Stone, Zoop and iFood, and reported more than R$300 million processed in its first year (its own figure). Per docs.unblockpay.com, the API covers customers (individual and business, with UBO capture and Sumsub verification), one custodial wallet per customer on Solana, Ethereum, Polygon, Tron and Base, external accounts over Pix, Pix bank account, SPEI, US domestic wire, SEPA and CVU with a third-party flag, named virtual accounts in USD and EUR, and four transaction types: pay-in, payout, wallet transfer and fiat-to-fiat, each on a five-minute locked quote with an optional partner fee. Its payment-methods guide lists Brazil and Mexico as live payout countries and Colombia as coming soon, while its external-accounts reference already documents wire, SEPA and CVU; both pages are current, so this page quotes both. The marketing site claims availability in 150+ countries and names SWIFT, ACH and Fedwire, which appear in the docs only as deposit methods for the USD account. UnblockPay operates under Article 88 of Central Bank Resolution 520/2025 while its VASP authorization is processed, and states that regulated services are provided by authorized partners.

What is Lumx?

Lumx is stablecoin payments infrastructure for businesses that move money between Latin America and the rest of the world: one API to collect, hold, convert, and pay out in BRL, MXN, COP, USD, EUR, and GBP or in USDC and USDT, over local rails such as PIX, SPEI, PSE, ACH, FEDWIRE, SEPA, and Faster Payments, with SWIFT and on-behalf-of payments and collections (POBO and COBO) in USD, EUR, and GBP, plus named virtual accounts, custodial wallets, and KYB/KYC built in.

Lumx was founded in 2022 in Rio de Janeiro and is backed by BTG Pactual, the largest investment bank in Latin America. Custodial wallets run in production, segregated per customer, on Ethereum, Polygon, Base and Tron, with Stellar for USDC on-ramps in BRL. In Brazil, Lumx SPSAV Ltda operates under Article 88 of Central Bank Resolution 520/2025; in the US, Lumx US OP LLC is a FinCEN-registered MSB (#31000316459619). Lumx processes more than $2B in annualized payment volume (as of September 2026). Customers include Nomad, Logcomex and Conta Simples.

How do Lumx and UnblockPay compare?

Model. Both sell one API for stablecoin payments with KYB/KYC inside, and both started from Brazil. The difference is the direction each one points its named accounts. UnblockPay issues them in USD and EUR, so a Brazilian or Mexican business gets a foreign account and pays locally over Pix or SPEI from per-payment instructions. Lumx issues them in six currencies, so the same business gets a BRL account with agência and conta, a CLABE and a COP account as well as USD, EUR and GBP. On rails, UnblockPay documents Pix, SPEI, US wire, SEPA and CVU as external-account types, with its own guide confirming Brazil and Mexico as live for payouts; Lumx runs PIX, SPEI, PSE, Bre-B, ACH, Fedwire, SEPA, Faster Payments and SWIFT in USD. UnblockPay's fiat-to-fiat endpoint, which quotes both legs of a Pix-to-SPEI conversion at once, is a product Lumx does not offer as one call. UnblockPay's Argentine rail is live; Lumx's is announced.

Custody. Both custody in production, one wallet per customer. UnblockPay runs USDC and USDT on Solana, Ethereum and Polygon, USDT on Tron and USDC on Base, with Arbitrum announced. Lumx runs USDC and USDT on Ethereum, Polygon, Base and Tron, with Stellar for BRL on-ramps. UnblockPay has Solana and Lumx does not; Lumx has both tokens on every chain it lists. For a product whose users hold a balance, the two are close, and the choice turns on chain and on what the balance can pay into.

Pricing and compliance. Neither publishes plans. UnblockPay embeds a percentage in the FX rate, publishes flat fees for some rails and lets partners add their own markup at quote time. Lumx charges a monthly platform fee plus usage-based per-transaction and virtual account fees, with transparent FX on locked quotes and no pre-funding; plans are not published, so contact sales. On regulation the Brazilian side is symmetric: both companies are VASP applicants operating under Article 88 of Resolution 520/2025 while their authorizations are processed, and both say regulated services run through authorized partners. The asymmetry is the US: Lumx US OP LLC is a FinCEN-registered MSB, and UnblockPay's site and docs name no US entity or registration. Both use Sumsub for KYC and KYB; Lumx adds token sharing for instant approvals, Chainalysis on-chain monitoring in its compliance stack, and purpose codes and holder relationships on every payment. UnblockPay's docs model a third-party boolean on external accounts and name Chainalysis only in a blog post.

When is Lumx the better fit?

• Your customers need a named account in BRL, MXN or COP. UnblockPay's named accounts are USD and EUR. See USDC to BRL, BRL to USDC, USDC to MXN and USDC to COP.

• You pay into Colombia or the UK. PSE, Bre-B and Faster Payments are live on Lumx; UnblockPay lists Colombia as coming soon and does not mention GBP.

• You need a US-registered counterparty. Lumx US OP LLC is a FinCEN MSB; UnblockPay publishes no US registration.

• You want a sandbox on sign-up. Lumx accounts open in a sandbox with mock partners and magic numbers; UnblockPay's quick-start says to contact its team for API keys.

• You need local reporting fields. Purpose codes and holder relationships (supplier, employee, subsidiary) are modeled on every Lumx payment; UnblockPay models a third-party flag.

• You settle SWIFT payouts. Lumx runs SWIFT in USD with UETR and MT103; UnblockPay documents SWIFT only as a deposit method for its USD account.

Where does UnblockPay fit?

UnblockPay does several things Lumx does not do, and this page should say so plainly.

• Fiat-to-fiat in one call. A single quoted transaction takes Pix in, holds a stablecoin and pays SPEI out. Lumx exposes the legs separately.

• A partner programme for FX correspondents. Dashboard, configurable spread at quote time, the partner owns the client relationship and keeps its markup. Lumx does not sell a white-label product of this kind.

• Argentina today. CVU is a documented external-account rail; Lumx has ARS announced.

• Solana. USDC and USDT on Solana, which Lumx does not run.

• Hosted onboarding by default. Customer creation returns a Sumsub verification link, so a partner can onboard without building a KYC flow.

Can you use Lumx and UnblockPay together?

Yes, though the overlap in Brazil and Mexico means most teams pick one there. The clean split is UnblockPay for a white-label FX offering or for Argentina, and Lumx for named accounts in six currencies, Colombia, the UK, SWIFT and a US-registered counterparty. Both settle USDC and USDT on Ethereum and Polygon, so a balance moves between them on-chain. Both lock a quote before executing and both send webhooks on status changes, so the reconciliation model is the same on each side.

How do you migrate from UnblockPay to Lumx?

1. Map UnblockPay customers and external accounts to Lumx customers and destinations. Both run Sumsub KYB and KYC; Lumx can import a prior Sumsub verification through token sharing. Lumx adds a holder relationship (SUPPLIER, EMPLOYEE, SUBSIDIARY and others) where UnblockPay had a third-party flag, and a purpose code on each payment.

2. Open a sandbox at dashboard.lumx.io. New accounts start in a sandbox with mock banking partners; magic numbers on taxId force approved, rejected or pending verification.

3. Replace per-payment instructions with named accounts. Customers who received Pix or SPEI from external-account instructions get a BRL, MXN or COP account in their own name; keep the USD and EUR accounts as they were.

4. Move balances out of UnblockPay wallets. Lumx custodial wallets are provisioned per customer on Ethereum, Polygon, Base and Tron; fund them with an on-chain transfer of USDC or USDT on a shared chain.

5. Split fiat-to-fiat into two quotes. A Pix-to-SPEI conversion becomes a pay-in to the BRL account and a payout from the balance, each on a locked quote (30 seconds free, one or five minutes for a fee).

6. Subscribe to webhooks and run parallel. Send Idempotency-Key on every mutation, reconcile both ledgers for one cycle, then move production traffic. Read the docs or talk to us.
