Rampper

Rampper is a decentralized, non-custodial peer-to-peer on/off-ramp built fully on-chain on Stellar. People swap between local fiat (PHP, IDR, VND — more coming) and crypto without trusting a centralized exchange: funds sit in a Soroban escrow contract — never with Rampper, never with the counterparty. Code, not trust.

At its core Rampper settles in USDC, the digital dollar, so liquidity pools into one deep, stable market instead of a hundred thin pairs. Want XLM or another asset? Rampper sources USDC and swaps it on-chain behind the scenes — you receive exactly the token you asked for, no extra step.

In one minute

• Makers provide USDC liquidity in on-chain vaults and quote a rate against the live market.
• A Taker signals an order, which locks the maker’s USDC in escrow.
• The taker pays fiat through a local rail (GCash, Maya, bank transfer), marks it paid, and the maker releases the crypto — settling in seconds.
• A platform arbiter backstops every trade as the dispute resolver, with a path toward fully trustless verification.

Why Rampper

• Non-custodial — escrow is a Soroban contract; Rampper can never freeze, move, or seize funds. Only the trade’s own rules release them.
• USDC at the core — every trade settles in USDC, concentrating liquidity into one deep, stable pool. Other tokens are reached via an automatic on-chain swap.
• Local rails, one app — APAC fiat methods quoted against a live order book of makers.
• Transparent pricing — a small platform fee shown upfront, hard-capped on-chain; makers set their own ±5% spread vs. the live rate.
