The neobank glossary — 50 terms, defined plainly

Updated July 2026 · the vocabulary behind the directory of 357 neobanks · questions answered in the FAQ

Account abstractionsmart accounts · ERC-4337: Technology that turns a crypto wallet into a programmable account: spending limits, session keys, social recovery, paying fees in stablecoins. It's what lets self-custodial neobanks feel like normal apps instead of key-management homework.
AMLanti-money laundering: The body of law requiring financial companies to monitor and report suspicious activity. AML obligations — not technology — are why accounts get frozen for review and why onboarding asks about the source of your funds.
APYannual percentage yield: Interest expressed with compounding included, the number neobanks advertise on savings. Nearly all headline APYs in the directory are "up to" rates gated behind direct deposits, subscription tiers or balance caps — the conditions matter more than the number.

Banking-as-a-ServiceBaaS: Licensed banks renting their charter, compliance and payment rails to fintechs via API. BaaS is how a startup ships "a bank account" in months. The 2024 Synapse collapse — a BaaS middleware failure — is the model's cautionary tale.
Banking licencebank charter: Regulatory permission to take deposits and lend. It's the strongest structure a neobank can have: deposit insurance applies and the regulator supervises directly. Only 92 of the 357 tracked neobanks hold one — the licence type is stated on every profile page.
BNPLbuy now, pay later: Point-of-sale instalment credit (Klarna, Affirm-style). Several neobanks bolt it onto their cards; regulators increasingly treat it as ordinary consumer credit.

Cashback: A rebate on card spend, funded from interchange, marketing budget or — in crypto programs — token incentives. The permanent asterisk: most rates are "up to", tiered by subscription or staking. When cashback exceeds what interchange can fund, ask what pays for it.
Challenger bank: The UK-born term for newly licensed banks challenging high-street incumbents — Monzo, Starling, Zopa. Broadly synonymous with wave-one neobanks, but implies a full banking licence. See neobank vs digital vs challenger.
Card issuer: The licensed institution that actually issues a card and owes the network compliance — often not the brand on the plastic. Behind most fintech and crypto cards sits a specialist issuer (Bancorp, Stride, Striga, Rain); when an issuer exits a program, the card dies overnight regardless of the app.
Chargeback: The card-network process for disputing a transaction and clawing money back. A big practical difference between card rails and crypto rails: stablecoin transfers have no chargebacks.
Custodycustodial · self-custodial: Who actually holds your money. Custodial: the company or its partner bank holds it, you hold a claim. Self-custodial: funds sit in a wallet only you control. The single most important attribute when comparing neobanks — the directory filters by it, and this guide unpacks it.

Deposit insuranceFDIC · FSCS · DGS: Government-backed protection that repays depositors if a licensed bank fails — up to $250k per depositor per bank in the US (FDIC), £85k in the UK (FSCS), €100k in the EU. It covers bank failure only: not fintech ledger errors, and never crypto balances.
DeFidecentralised finance: Financial services (lending, swapping, yield) running as smart contracts rather than companies. Web3-native neobanks often route idle balances into DeFi yield — which is where "4% on your USDC" usually comes from, with smart-contract risk attached.
Direct deposit: Salary paid straight into the account — the loyalty signal neobanks prize most. Many headline perks (early payday, top APY tiers, fee waivers) unlock only with direct deposit, because it marks you as a primary-account customer rather than a test balance.
Digital bank: Any bank served primarily through digital channels — includes both independent neobanks and digital arms of incumbents (Marcus by Goldman Sachs, isybank by Intesa). Broader than "challenger", narrower than "neobank".

E-money institutionEMI · e-money licence: A licence (common in the UK/EU) to issue electronic money and run payment accounts — but not to lend deposits. Customer funds must be safeguarded, not insured. Wise, Tide and many European "neobanks" are EMIs, not banks.
E-money tokenEMT: MiCA's legal category for fiat-pegged stablecoins issued in the EU — full reserves, redemption at par, issuer authorisation required. The regulatory wrapper that let European neobanks touch stablecoins at all.

FDICFederal Deposit Insurance Corporation: The US deposit insurer. "FDIC-insured" on a neobank's landing page means a partner bank holds the funds — the insurance attaches to the bank, not the app. See the FAQ answer for what it does and doesn't cover.
Financial inclusionunbanked · underbanked: Serving people outside the traditional banking system — no credit history, no branch nearby, no ID that banks accept. The strongest neobank growth stories (TymeBank, OPay, Nubank, bKash) are inclusion stories; 21 tracked neobanks name the underbanked as their audience. More: banking the underbanked.
FX spread: The hidden margin added to an exchange rate when you spend or send in another currency. Often the largest fee a neobank charges, and never listed on the fee page as a fee. Compare against the mid-market rate to see it.

GENIUS Act: The 2025 US federal law regulating payment stablecoins: full reserves, audits, redemption rights. It turned the largest stablecoins from regulatory grey zones into supervised instruments — the precondition for mainstream neobanks touching stablecoin rails.
Gas fees: Per-transaction fees paid to a blockchain network. Modern self-custodial neobanks hide them via account abstraction or cheap L2 networks — if you're quoted gas in 2026, the product is showing its plumbing.

IBAN: International Bank Account Number — the account identifier for SEPA/European transfers. "Your own IBAN" from a wallet product means a partner EMI or bank issued it; whose name it sits in determines how transfers reconcile.
Interchange: The fee (roughly 0.2–2% by region and card type) a merchant's bank pays the card issuer on every swipe — the original neobank business model. US debit interchange for small issuers is why US neobanks could be free; capped EU interchange is why European ones charge subscriptions.

KYCknow your customer: Identity verification required before opening a custodial account — ID document, selfie, sometimes proof of address. Self-custodial products need no KYC for the wallet itself, only for the card (issued by a licensed partner). The "no-KYC" spectrum is mapped in this guide.

L2layer-2 network: A faster, cheaper blockchain settling to a main chain (Base, Arbitrum, Gnosis Chain). Most self-custodial card programs run on L2s because sub-cent fees make everyday payments viable.
Licence passporting: Using one EU/EEA country's authorisation to operate across all of them. Why so many European neobanks are licensed in Lithuania or Ireland but serve the whole continent.

MiCAMarkets in Crypto-Assets Regulation: The EU's comprehensive crypto framework, fully applicable since end-2024. It licenses crypto-asset service providers and stablecoin issuers, and is the reason hybrid neobanks can offer crypto legally across Europe. Explainer: MiCA and crypto neobanks.
Money transmitter licenceMTL: US state-level licences for moving money without being a bank. A patchwork — one per state — which is why US fintechs lean on partner banks instead.
MPC walletmulti-party computation: Self-custody where the private key is split into shares (your device, a recovery service) so no single party — including the company — can move funds alone. The middle ground between custodial convenience and raw seed-phrase self-custody.

Neobank: A digital-first financial service offering everyday banking — account, card, payments — through an app, without branches. Spans three waves in 2026: traditional fiat challengers, hybrid crypto apps, and self-custodial web3-native services. The founding definition of this site: what is a neobank?
Neobroker: App-first investment platforms (Trade Republic, Robinhood). Increasingly indistinguishable from neobanks — both added the other's features; Trade Republic and Robinhood now appear in the directory because they ship cards and pay yield on cash.
Niche neobank: A neobank built for a named audience — teens, women, immigrants, freelancers, faith communities, gig workers — rather than everyone. 117 of the 357 tracked neobanks serve a niche. Map: the niche wave.

On-ramp / off-ramp: The bridge between fiat and crypto: on-ramp converts bank money to stablecoins, off-ramp converts back. Card programs are effectively continuous off-ramps — spend crypto, merchant receives fiat.
Open bankingPSD2: Regulation forcing banks to open account data and payments to licensed third parties via API. What lets a neobank show your other bank accounts in one feed, and what account-to-account payments are built on.

Partner banksponsor bank: A chartered bank holding deposits and issuing cards on behalf of a fintech (The Bancorp Bank and Stride behind Chime). The customer's insurance lives at the partner; the fintech runs the app and the ledger. Where that ledger breaks, so does access to funds — the Synapse lesson.
Payment institutionPI: A licence for executing payments (transfers, acquiring, remittance) without issuing e-money or taking deposits. One rung below an EMI; several tracked neobanks in Africa and Asia operate under national payment-institution or payment-service-bank regimes.
Prepaid card: A card spending a stored balance rather than a bank account or credit line. Lighter KYC thresholds make prepaid the chassis for most "no-KYC" crypto cards — with matching low limits.

Remittance: Cross-border money transfer, usually by migrant workers to family — a $700B/year market averaging 6%+ in fees. The clearest use case where stablecoin rails undercut incumbents, and the business model behind immigrant-focused neobanks.

Safeguarding: The EMI rule: customer funds must be held separately from company money, at a bank or in low-risk assets, so they survive the company's insolvency. Weaker than deposit insurance — recovery takes time and can bear wind-down costs — but far better than commingling.
Seed phraserecovery phrase: The 12–24 words that regenerate a self-custodial wallet's keys. Whoever holds them holds the money; lose them (with no other recovery set up) and no support line can help. Modern products replace them with passkeys and MPC.
Smart account: See account abstraction — a contract-based wallet with programmable rules, the technical foundation of the web3-native neobank wave.
StablecoinUSDC · USDT: A crypto token pegged 1:1 to a fiat currency and backed by reserves. Post-GENIUS and MiCA, the large ones are supervised instruments. For neobank users they are dollar accounts without a US bank — with issuer risk instead of bank risk. Primer: stablecoin cards explained.
Super-app: One app bundling banking, payments, shopping, travel and more — the Asian playbook (GCash, Kaspi, PayPay) that Revolut is chasing in Europe. The opposite strategy of the niche neobank.

Tokenised deposit: A bank deposit represented on a blockchain — bank liability, deposit insurance intact, programmable rails. The incumbents' answer to stablecoins; pilots at JPMorgan and others.

Underbanked: Having some access to financial services but relying on expensive alternatives (cheque cashing, payday loans, cash). Distinct from unbanked (no account at all). Together they are the target market of the most consequential neobanks in the dataset.

Virtual card: A card number that exists only digitally — created instantly, frozen or rotated per merchant. Standard neobank kit for online spending hygiene and the default form factor of crypto card programs.

Web3-native neobank: The third wave: self-custodial wallets wrapped in banking UX — card, IBAN, yield — where the company never holds funds. 47 tracked in the directory. The trade: no company risk, but you carry key management. Deep dive: self-custodial neobanks.

x402machine payments: An HTTP pattern reviving status code 402 Payment Required: a server quotes a price, the client (often an AI agent) pays in stablecoins, the resource unlocks. The foundation of agent-to-machine commerce — and the reason "neobanks for AI agents" appear in the future-narratives chapter of the report.

Yield: Any return paid on balances — bank interest, money-market funds, or DeFi lending depending on the product's structure. The source determines the risk: FDIC-insured interest, fund NAV risk, or smart-contract risk can all hide behind the same "4%". Always ask where yield comes from.
