Glossary
Plain definitions of the words you will meet when you use the Bitzaro Card, the Bitzaro Wallet or Wallet-as-a-Service (WAAS and WAAS Lite). Each entry says what the term means, then how it works at Bitzaro.
Bitzaro Card
Bitzaro Card
A Visa card from Bitzaro for spending your crypto wherever Visa is accepted, online and in store.
At BitzaroYou apply for it in the Bitzaro Wallet app, and it comes as a virtual card, a physical card, or both.
Virtual card
A card that exists only in an app, with card details you can use for online checkout or add to a phone wallet.
At BitzaroThe virtual Bitzaro Card appears in the Card tab of the Bitzaro Wallet once your application is approved. It is free to issue and has a $5 annual fee. It cannot be used for cash at ATMs.
Physical card
A card you carry, for paying in store and taking cash out at ATMs.
At BitzaroThe physical Bitzaro Card is ordered from the Card tab. Bitzaro gives 14 to 30 days for it to arrive. It costs 50 USDT to issue and has a $25 annual fee.
Card balance and Reload
The money on a payment card that you can spend, kept apart from the account it was topped up from.
At BitzaroThe Bitzaro Card spends its own balance, separate from your Bitzaro Wallet balance. You top it up in the app's Card section with Reload, which moves USDT from your wallet to the card. The reload fee is 0.5% of the amount, with a 3 USDT minimum.
Card eligibility
Whether you can get the Bitzaro Card depends on the country of your verified residential address, not on your nationality.
At BitzaroMost countries are supported. A small number are not, and in some only the virtual card is available. Bitzaro does not serve clients in the United Kingdom.
Freezing a card
Blocking a card for a while so that new payments are declined, without cancelling it.
At BitzaroYou freeze and unfreeze the Bitzaro Card from the Card tab in the Bitzaro Wallet app. A frozen card declines every new authorisation; payments already authorised may still settle.
Google Pay
Google's phone wallet, for paying contactless with a card stored on your phone.
At BitzaroThe Bitzaro Card can be added to Google Wallet by entering the card details by hand; one-tap adding isn't available yet. Its terms are at bitzaro.com/googlepay-terms.
Dynamic currency conversion (DCC)
An offer from an ATM or card terminal abroad to charge you in your home currency, at the machine's own exchange rate, instead of the local currency.
At BitzaroBitzaro recommends declining any conversion offered by the ATM or terminal and choosing to be charged in the local currency.
Wallet and crypto basics
Bitzaro Wallet
Bitzaro's crypto wallet, as an app and at wallet.bitzaro.com, for holding, sending and receiving crypto.
At BitzaroYou sign in with your email and a one-time code and add two-factor authentication; there is no seed phrase. It holds USDT and USDC on Ethereum, BNB Smart Chain, Tron and Solana, and it is the account behind the Bitzaro Card.
Stablecoin
A cryptocurrency designed to have a stable value, often pegged to a currency such as the US dollar.
At BitzaroBitzaro works with two stablecoins, USDT and USDC.
USDT (Tether)
A stablecoin issued by Tether, which says each token is pegged 1-to-1 to the US dollar. It exists on several blockchains.
At BitzaroUSDT is the main asset across Bitzaro: you reload the Bitzaro Card with it, the Wallet holds it on four networks and charges network fees in it, and WAAS Lite collects it.
USDC
A stablecoin issued by Circle, which says it is redeemable 1:1 for US dollars.
At BitzaroThe Bitzaro Wallet holds USDC alongside USDT on Ethereum, BNB Smart Chain, Tron and Solana.
Blockchain network
The blockchain a crypto transfer travels on. The same coin can exist on several networks, and the sending and receiving networks must match.
At BitzaroBitzaro supports Ethereum, BNB Smart Chain (BSC), Tron and Solana. Bitzaro warns that sending on the wrong network can stop the funds being credited, and recovery may not be possible.
Gas (network fee)
The fee paid to a blockchain for processing a transaction, normally paid in that network's own token, such as ETH, BNB or TRX.
At BitzaroIn the Bitzaro Wallet, network fees come out of your USDT balance, so you never need to buy a separate gas token, and the fee is shown before you confirm.
Seed phrase
A list of words given to you when you create many crypto wallets. It acts like a password for the wallet.
At BitzaroThe Bitzaro Wallet does not use one. You sign in with your email, a one-time code and two-factor authentication, so there is nothing to write down or lose.
Multisignature
A Bitzaro Wallet feature for situations where stronger approval or multi-party authorization is required before funds can be moved.
At BitzaroA wallet in the Bitzaro Wallet app can be Standard or Multisignature.
Transaction hash
A unique identifier for a blockchain transaction. You can look it up on a blockchain explorer to see its status, addresses, amount and confirmations.
At BitzaroIf a transfer goes wrong, keep the transaction hash, the asset, the amount and the network used, and give them to Bitzaro support.
Confirmations
A sign that a blockchain transaction has been included in the network's history and that more blocks have been added after it.
At BitzaroA Bitzaro product can wait for a minimum number of confirmations before it treats a payment as complete, which is why a transfer can show as successful on the blockchain but still be pending in Bitzaro.
Onramp
A fiat-to-crypto service: you pay in ordinary money and receive crypto.
At BitzaroBitzaro Onramp can be built into a merchant's own app or website, and WAAS Lite customer wallet links include it, so a customer can buy crypto and deposit it in one step. Availability depends on the country.
Wallet-as-a-Service (WAAS and WAAS Lite)
Wallet-as-a-Service (WAAS)
A service that lets a business give its users crypto wallets through an API, without building custody, key management and blockchain infrastructure itself.
At BitzaroBitzaro WAAS is one API for creating wallets, moving funds and paying out, with custody and fraud checks handled by Bitzaro. It is the engine behind every Bitzaro product.
WAAS Lite
Bitzaro's dashboard version of Wallet-as-a-Service, for collecting crypto payments without writing code.
At BitzaroIt runs on the same engine and account as WAAS, so a team can start in the console and add the API later without migrating balances. It collects on Ethereum, BNB Smart Chain and Tron.
Custody
Holding and protecting the private keys that control crypto funds.
At BitzaroWith Bitzaro WAAS, Bitzaro holds custody: it holds and protects the keys, keeps balances segregated per user, and gives you access to them through the API.
MPC wallet
A wallet whose transactions are signed through multi-party computation (MPC), so that no single private key exists to be lost or stolen.
At BitzaroBitzaro WAAS wallets are created and signed this way.
White label
Running a service under your own brand while another company provides it behind the scenes.
At BitzaroWith Bitzaro WAAS, wallets, payment pages and payout flows can carry your brand.
API key
A credential your own system uses to prove who it is when it calls an API. Keep it secret and never put it in a web page or app.
At BitzaroBitzaro WAAS issues sandbox and live keys. In WAAS Lite you generate one from the dashboard, and only if you want to automate.
Sandbox (test environment)
A test environment for building and trying an integration before using live keys.
At BitzaroBitzaro WAAS issues sandbox and live API keys; WAAS Lite merchants get a test (UAT) environment during onboarding.
Webhook
A message one system sends to another's web address the moment an event happens, so the receiving system doesn't have to keep asking.
At BitzaroWAAS Lite sends four: Onetime Payment Callback, Chain Event, Gathering and User KYC. The technical reference is at waaslite.readme.io.
Onetime Payment Link
In WAAS Lite, a payment request tied to one order. The customer pays it, and the merchant releases the goods once it is paid.
At BitzaroA link can fix one token on one chain, or one token on any of Ethereum, BSC and TRON. It accepts partial payments until the order is paid in full.
Fixed-chain and any-chain links
The two kinds of WAAS Lite payment link. A fixed-chain link gives one address, and the customer must pay with that exact token and chain. An any-chain link gives up to three addresses, on Ethereum, BSC and TRON, for the same token.
At BitzaroAn any-chain link lets the customer pay on whichever of the three chains is easiest for them.
Partial payment
Paying one order in several transfers.
At BitzaroWAAS Lite adds the transfers up, even when they arrive on different chains, until the order amount is reached.
Client (WAAS Lite)
In WAAS Lite, a record for one of the merchant's own customers or members.
At BitzaroEach Client gets a dedicated wallet address and a unique wallet link, without needing a full Bitzaro account, so every payment is matched to the right customer.
Gathering
In WAAS Lite, moving funds from your Clients' wallets into your main merchant balance.
At BitzaroThe merchant starts it, and each payment stays attributed to its Client. A webhook fires when it completes.
Gas Station
The WAAS Lite tool that manages the blockchain gas a merchant's operations need.
At BitzaroYou top it up with each chain's own token; it shows your gas balance on each chain and logs every use.
Self-Healing
A WAAS Lite safeguard that keeps funds correctly classified when the risk level of where they came from changes after payment.
At BitzaroIf a source address's risk level rises, the funds are moved to the matching higher-risk wallet, and the move is logged in Replace History.
Replace History
The WAAS Lite record of every address move made by Self-Healing.
At BitzaroEach entry shows the old address, the new address, the reason, the time and the blockchain, for reconciliation and fund tracing.
Safety and compliance
KYC (Know Your Customer)
The process of verifying an individual's identity.
At BitzaroBitzaro verifies every customer through Sumsub before they can hold a balance. For the card this includes a valid photo ID and a live selfie.
KYB (Know Your Business)
Verification of a business customer: its registration, address, directors or representatives, and owners where applicable.
At BitzaroWAAS Lite onboarding includes a business verification step.
KYT (transaction screening)
Screening crypto transfers for risk, such as links to sanctioned or stolen funds, before they settle.
At BitzaroBitzaro screens incoming and outgoing transfers against Elliptic's on-chain risk data, and funds tied to sanctioned or stolen sources are held for review.
Risk levels (LOW, MED, HIGH)
The three risk classes WAAS Lite gives the wallet a payment came from.
At BitzaroLOW and MED payments move to the merchant balance automatically. HIGH payments wait for the merchant to approve or reject them; a rejected payment is refunded to its source.
Risk Matrix
Bitzaro's risk-analysis layer for wallet and transaction workflows.
At BitzaroIt combines blockchain analytics with Bitzaro's own risk rules. Bitzaro notes that it "does not guarantee that a wallet, transaction or counterparty is safe or unsafe".
Two-factor authentication (2FA)
A second check, such as a code from an authenticator app, on top of your normal sign-in.
At BitzaroThe Bitzaro Wallet asks you to add 2FA after sign-up, and WAAS Lite withdrawals need a Google Authenticator code.
