India
| Rail | Settlement | Finality | Reversibility | Cost | Max amount | Regulator / Operator | P2P | P2M | Recurring | Currency | Crypto on/off-ramp fit |
|---|---|---|---|---|---|---|---|---|---|---|---|
| UPI | <5s | Instant | None (raise dispute via PSP / NPCI ODR) | Zero MDR for P2M; bank-fee absorbed | ₹1L (₹5L some categories) | RBI / NPCI | Yes | Yes | UPI AutoPay (e-mandate) | INR | Bank partner (sponsor) → UPI handle / VPA collect. Travel Rule for crypto purchase reporting via FIU-IND. |
| IMPS | <30s | Instant | None (return only on failed credit) | ₹2.5–₹15 (bank-set) | ₹5L | RBI / NPCI | Yes | Yes | No native mandate | INR | A/C+IFSC or MMID. Used as fallback when UPI handle isn't known. |
| NEFT | 30 min batches, 24×7 | Deferred | Return on failed credit only | ₹2.5–₹25 | None (bank-set) | RBI | Yes | Yes | NACH e-mandate adjacent | INR | Legacy fallback for large off-ramp payouts where IMPS cap binds. |
| RTGS | Real-time during window | Instant (gross) | None | ₹25–₹50 (bank-set) | None; min ₹2L | RBI | No | Yes (high-value) | No | INR | Institutional off-ramp; bulk corporate settlement. |
More detail on UPI
UPI is the world's largest real-time retail rail by volume. Integrators plug in via a sponsor bank as TPAP (Third-Party Application Provider) or PSP bank. NPCI is the scheme operator; RBI is the regulator. UPI collect request is the typical on-ramp pattern (exchange shows VPA, user approves in their UPI app). UPI AutoPay supports e-mandates up to ₹15K without re-auth (variable up to limit). Travel Rule and FIU-IND reporting apply to crypto purchases above PMLA thresholds.
Brazil
| Rail | Settlement | Finality | Reversibility | Cost | Max amount | Regulator / Operator | P2P | P2M | Recurring | Currency | Crypto on/off-ramp fit |
|---|---|---|---|---|---|---|---|---|---|---|---|
| PIX | <10s, 24×7 | Instant | MED (special return mechanism) for fraud, narrow window | Zero for P2P; ~0.22–1.45% P2M | None (bank-set; per-user caps overnight) | BACEN | Yes | Yes | Pix Automático (rolling out 2025) | BRL | Sponsor bank or Direct Participant. PIX QR collect or Pix key. MED process is the closest thing to a chargeback — narrow and discretionary. |
| TED | Same-day during window | Instant (gross) | None post-settlement | R$5–R$50 (bank-set) | None | BACEN | Yes | Yes | No | BRL | Legacy high-value; mostly displaced by PIX for off-ramp. |
| DOC | T+1 | Deferred | Return on fail | R$5–R$15 | R$4,999.99 | BACEN | Yes | Yes | No | BRL | Effectively retired; avoid for new integrations. |
| Boleto | 1–3 business days | Deferred | None once paid; expires unpaid | R$1.50–R$3.50 flat | None | BACEN / Febraban | No (push only) | Yes | No | BRL | Push-payment voucher. Useful for unbanked on-ramp; high non-payment rate (issued ≠ paid). |
Europe / SEPA
| Rail | Settlement | Finality | Reversibility | Cost | Max amount | Regulator / Operator | P2P | P2M | Recurring | Currency | Crypto on/off-ramp fit |
|---|---|---|---|---|---|---|---|---|---|---|---|
| SEPA Credit Transfer (SCT) | 1 business day | Deferred | Recall request via originator bank; beneficiary must consent | €0.05–€0.30 (PSP-set; often free retail) | None (bank-set) | EBA / ECB; EPC scheme | Yes | Yes | SDD (Direct Debit) covers pull/mandate | EUR | IBAN-based; EMI license (or partner) for E-money in SEPA scope. |
| SCT Inst (SEPA Instant) | <10s, 24×7 | Instant | None post-confirmation (only return on unsettled) | From 2025: must match SCT (often free retail) | €100K (raised from prior cap) | EPC | Yes | Yes | SEPA Request-to-Pay (SRTP) for one-tap pull | EUR | Instant Payments Regulation (IPR) mandates parity and VoP (verification-of-payee) by Oct 2025. |
| TIPS | <5s | Instant | None | €0.002 per transaction (operator fee) | €100K (scheme-level) | ECB (Eurosystem) | Wholesale | Wholesale | n/a | EUR / SEK (multi-currency) | Underlying settlement layer for SCT Inst — banks reach it; integrators don't directly. |
| SEPA Direct Debit (SDD) | 1–5 business days | Deferred | 8-week unconditional refund; 13-month for unauthorized | €0.10–€0.50 | None | EPC | No | Yes (pull) | Yes (mandate) | EUR | Subscription model; high reversibility makes it bad for crypto on-ramp at scale. |
United Kingdom
| Rail | Settlement | Finality | Reversibility | Cost | Max amount | Regulator / Operator | P2P | P2M | Recurring | Currency | Crypto on/off-ramp fit |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Faster Payments (FPS) | <2h (usually seconds) | Instant | None (APP-fraud reimbursement now mandatory) | £0.01–£0.10 (PSP-set) | £1M (raised 2022) | PSR / Pay.UK | Yes | Yes | Standing orders; VRP (variable recurring payments) via OB | GBP | Direct participant via Pay.UK or sponsor bank. APP-fraud reimbursement rules (PSR 2024) bite hard on crypto purchase fraud. |
| BACS | 3-day cycle (D, D+1, D+2) | Deferred | Indemnity claim (DD); return for credit | £0.05–£0.20 | None | Pay.UK | Rare | Yes | Direct Debit (mandate) | GBP | Payroll, subscriptions. Bad for crypto on-ramp (reversibility, latency). |
| CHAPS | Same-day (RTGS) | Instant (gross) | None | £15–£35 | None | BoE | Rare | Yes (high-value) | No | GBP | Institutional / property. Used for bulk fiat treasury moves. |
| Open Banking (OB) | Rides FPS (instant) | Instant | Same as FPS | £0.10–£0.50 PIS fee | £1M (FPS limit) | FCA / OBL | Yes | Yes | VRP (sweeping; commercial VRP rolling) | GBP | Pay-by-bank via PIS providers (TrueLayer, Tink, GoCardless, Yapily). Dominant UK crypto on-ramp pattern. |
United States
| Rail | Settlement | Finality | Reversibility | Cost | Max amount | Regulator / Operator | P2P | P2M | Recurring | Currency | Crypto on/off-ramp fit |
|---|---|---|---|---|---|---|---|---|---|---|---|
| ACH | 1–3 business days | Deferred | Return up to 60 days (unauthorized consumer) | $0.20–$1.50 | $1M (Nacha rule); operator-bound | Fed / Nacha | Yes | Yes | Yes (ACH debit mandate) | USD | Plaid + Stripe/Modern Treasury common pattern. Reversal risk = exchanges hold crypto until ACH clears (3–5d). |
| Same-Day ACH | Same business day (3 windows) | Deferred | Same as ACH | $0.30–$2.00 + premium | $1M per txn | Fed / Nacha | Yes | Yes | Yes | USD | Faster settlement, same reversal risk. Same 60-day consumer return window. |
| FedNow | <20s, 24×7 | Instant | None post-settlement | ~$0.045 (Fed fee) + bank markup | $1M (default $500K) | Federal Reserve | Yes | Yes | Limited (request-for-payment) | USD | Sponsor bank participation required. Adoption still growing; not yet a mass crypto on-ramp default. |
| RTP (TCH) | <15s, 24×7 | Instant | None | ~$0.045 + bank markup | $10M (raised 2025) | OCC / TCH | Yes | Yes | RfP (request-for-payment) | USD | Bank-owned network; broader large-bank coverage than FedNow today. Best US instant off-ramp. |
| Fedwire | Real-time, business hours | Instant (gross) | None | $15–$40 (bank-set) | None | Federal Reserve | Rare | Yes (high-value) | No | USD | Institutional / treasury. Crypto exchanges receive fiat from large clients here. |
| SWIFT (correspondent wire) | 1–5 business days | Deferred (per leg) | Recall via originator; beneficiary consent | $15–$50 + intermediary cuts | None | SWIFT (BIC) | Rare | Yes | No | Multi-currency | Cross-border fiat — slow, opaque. Crypto-as-rails (USDC/USDT) frequently outperforms here. |
More detail on ACH vs RTP vs FedNow
ACH is cheap and ubiquitous but carries up to 60-day consumer return risk under Nacha rules — crypto exchanges either (a) hold crypto for ~5 days post-deposit or (b) underwrite the reversal risk. Same-Day ACH cuts settlement to hours but does not change the return window. RTP and FedNow are truly final on settlement. RTP launched 2017 with TCH (bank-owned); FedNow launched 2023 by the Federal Reserve. They are interoperable in spirit but not yet at the bank-participation level — your sponsor bank must enable each separately. The $10M RTP cap and $1M FedNow cap diverge.

Why card MCC 6051 / 6012 matters for crypto
MCCs 6051 (Quasi-Cash / Foreign Currency / Crypto) and 6012 (Financial Institution — Manual Cash Disbursement) are how issuers identify crypto purchases. Many issuing banks decline these by default or apply a cash-advance fee, even when the merchant is licensed. This is the largest hidden tax on card-based crypto on-ramps.
Mobile wallets & pseudo-rails
These are acceptance methods, not independent rails. They tokenize underlying card or bank credentials.
| Wallet | Geography | Underlying rail | Cost impact | Settlement | Recurring | Crypto on-ramp fit |
|---|---|---|---|---|---|---|
| Apple Pay | Global | Card (tokenized PAN) | Same as card MDR | Card-cycle | Yes | Card-rail inherits all card limitations (MCC, chargeback). |
| Google Pay | Global | Card or UPI (IN) | Same as underlying | Per underlying | Yes | In India, GPay rides UPI — different economics from card-mode. |
| GCash | Philippines | Wallet + InstaPay / PESONet | Wallet fee | Instant (wallet) | Yes | BSP EMI; dominant PH wallet on-ramp. |
| GrabPay | SE Asia (SG, PH, MY, TH, +) | Wallet + local instant rails | Wallet fee | Instant (wallet) | Yes | Per-country licensing; Grab Financial Group. |
| Paytm | India | UPI + wallet | Free P2M | Instant | Yes (UPI AutoPay) | RBI PA license; UPI handle aggregation. |
| Maya | Philippines | Wallet + InstaPay | Wallet fee | Instant | Yes | BSP digital bank; competes with GCash. |
