Nylo Pay Back to homeNylo Pay turns crypto on Base into a card you check out with — no bank, no account, no identity verification. This document describes how it works, the architecture beneath it, and where it's headed.
Nylo Pay is a crypto-funded checkout layer. You fund an order with crypto on Base, Nylo issues you a card, and you check out at everyday online merchants — without a bank account, a sign-up, or an ID upload. Nylo bridges self-custodied crypto and ordinary online commerce while keeping card data off our servers and your chain identity away from merchants.
Crypto is still hard to spend. Most cards that promise to fix that pull you straight back into the banking system — accounts, credit checks, identity verification, and region gating — before you can buy anything. Stablecoins end up sitting idle in a wallet instead of being usable money.
Nylo's premise is narrow and practical: let people convert crypto into spendable card balance at the moment of checkout, with as little friction and as little disclosure as the rails honestly allow.
Three steps, usually under a minute end to end:
Three layers move value from an on-chain deposit to a usable card, with a hard boundary between Nylo and the card number itself.
Every order gets a fresh, single-use deposit address derived on Base. Incoming USDC is watched on-chain, confirmed to a safe depth, and swept to treasury. An idempotent ledger keys each deposit by its transaction so nothing is ever double-counted or replayed.
Once a deposit confirms, Nylo sources a card through a licensed card partner and returns a redemption code — a store gift card where supported, or a prepaid Visa/Mastercard elsewhere. Nylo never receives or stores the card number server-side, keeping card data out of scope.
A browser extension surfaces the card at checkout and autofills the merchant form for you. Card details live only in your browser for that moment — they are never sent to or kept on Nylo's servers.
Nylo's privacy comes from the card boundary, not from obscuring the chain. We want to be precise about what that does and does not mean:
Nylo settles on Base and accepts USDC at launch. A dollar-denominated stablecoin keeps the amount you send equal to the balance you get — no slippage between quote and settlement. Additional networks and assets follow as the product matures.
Nylo Pay is in early access and rolling out gradually. This document describes the system's design and direction; details, limits, and supported regions may change as the product develops. It is not an offer of securities, investment advice, or a guarantee of availability in your jurisdiction. Card issuance is provided through licensed partners, and usage limits apply.
