RAMP × STRIPE × PRIVY · STABLECOINS, EXPLAINED SIMPLY
Ramp, Stripe, and Privy just rebuilt how businesses hold and move dollars — using stablecoins instead of banks. This site maps the whole thing for someone with zero crypto background: how a payment actually travels, where the fees hide, who earns quietly off your idle cash, and what the banking industry just lost. Four sections, top to bottom:
The same payment, two ways: the traditional bank wire (how most businesses do it today) vs. the Ramp + Stripe + Privy stablecoin model. Follow the money top to bottom. Colored tags show who owns each step, where fees are charged, who earns money quietly, and how long it takes.
Your money hops between banks like a relay race. Each runner takes a cut.
Before you even pay anyone, your idle cash is earning interest — for the bank. Most business checking accounts pay you ~0%.
Only works on business days, before a daily cutoff time (often ~2–5pm). Miss it and everything starts tomorrow.
SWIFT is a messaging network owned by the banks themselves. It doesn't move money — it tells banks to update their ledgers.
If your bank has no relationship with the supplier's bank, 1–3 middlemen banks bridge the gap. Each one takes a "lifting fee" and adds a day.
The exchange rate you get is worse than the real rate — the difference (the "spread") is profit for the bank. Often the biggest hidden cost of all.
Days later, and less money than you sent. If anything went wrong, tracing it means calling banks one by one.
Your dollars become digital tokens that move like email — any time, in minutes.
Send dollars by ACH/wire; they're converted to stablecoins (digital tokens, each backed by $1 of real assets). Ramp charges no conversion fee. The account is really a digital wallet built by Privy, with the tokens held safe by Bridge — both owned by Stripe.
Every token is backed by real dollars invested in US Treasury bills. That interest used to go 100% to banks or coin issuers. Here it's split: Bridge takes a slice, Ramp takes a slice, and Ramp passes you up to 3.25% as "rewards."
The blockchain is a shared public ledger no single company controls. Transfer settles in seconds-to-minutes, 24/7/365, with a permanent record anyone can verify. Ramp covers the tiny network ("gas") fee.
A) Supplier accepts stablecoins (140+ countries): done, they got digital dollars directly. B) Supplier wants local currency (40+ currencies): Bridge converts and pays out over local rails. This conversion is where Ramp and Bridge charge their fee — smaller than the bank version, but not zero.
Same day — often within minutes. Both sides can see the transaction on the public ledger.
The fees didn't vanish — they got smaller, and moved to new owners. Here's each player's cut:
Keeps a slice of the ~4% reserve interest (pays you up to 3.25%, keeps the rest) · fees on currency conversion/payouts · interchange: ~2% paid by merchants every time its cards are swiped · subscription software.
Bridge charges small fees on every conversion and payout, and takes its own slice of the reserve interest before Ramp's. Stripe also earns card-processing fees on the card programs it runs for Ramp.
Charges platforms usage-based fees for creating and securing digital wallets. Now Stripe-owned, it's the piece that lets Ramp give every customer a wallet without building crypto tech.
Visa still earns on every card swipe · a sponsor bank (Lead Bank) earns for lending its license · BlackRock/Fidelity earn fees managing the reserves. Fewer middlemen per payment — but not zero.
Every dollar the new players earn falls into one of four buckets: captured from banks, reshuffled from the card industry, net-new ground banks never touched — or the sliver banks still keep.
The single biggest transfer. Idle cash interest — roughly half of a bank's revenue model — leaves the banking system.
Correspondent banks aren't repriced — they're deleted from the route entirely.
Same product, smaller price, new owner.
The bank shrinks to a rented license: Lead Bank collects basis points for lending its charter.
Fraud, disputes, statements — bank plumbing resold as software.
A firm in Mexico or Nigeria couldn't get a US corporate card. Every swipe is revenue that never existed.
Businesses in devaluing currencies holding digital dollars = deposits created, not stolen.
"Accounts as an API" and "launch your own dollar, keep the yield" are brand-new product categories.
70%+ of volume moves outside banking hours; card money earns yield until the second it's spent.
Cards legally need a bank. Lead Bank rents its license — a fee, not ownership.
Getting dollars in and out still runs through ACH/wires — bank rails, ~1 day.
The T-bills backing every token sit with BlackRock, Fidelity & co., earning management fees.
The fine print, in plain English: the 3.25% is legally a "reward," not interest (a 2025 law bans stablecoin issuers from paying interest, so it's routed through Ramp instead — and requires $5,000+ monthly deposits and 5+ payments to qualify). Stablecoin balances are not FDIC-insured like a bank account. And the fiat edges — moving dollars in, or paying out to a regular bank account — still run on the old rails and still take about a day. The blockchain middle is instant; the doors in and out are not.
