Stellar Regional Starter Pack
A toolkit and reference implementation for building applications that use those on/off ramps. Includes a portable anchor library, pre-built integrations with high-quality anchors, and a composable SEP protocol library.
The Local Currency Advantage
Most crypto on- and off-ramps route through USD - converting local currency to dollars, then dollars to a stablecoin, and back again on the way out. Every hop adds fees, delay, and counterparty risk.
Stellar changes this by supporting locally denominated digital assets: stablecoins and stablebonds pegged directly to local currencies like MXN or BRL. When you can go from pesos to a peso-denominated token on Stellar in a single step, you eliminate the USD detour entirely.
Yield-bearing assets like stablebonds take it further. Backed by local government treasury instruments, the yield they generate can be passed on as lower conversion costs (often below 25 basis points). That is an order of magnitude cheaper than traditional remittance and FX corridors.
What We Look For
Not every anchor is the same. We curate integrations that meet five criteria designed to ensure a great experience for developers and end-users alike.
- Locally denominated asset (stablecoin or stablebond) on Stellar
- Support for local payment rails connected to Stellar
- Competitive rates (wholesale <25 bps conversion)
- Well-documented open access for application developers
- Deep liquidity for low slippage (local <-> global assets)
What's Inside
Portable Anchor Library
Framework-agnostic TypeScript clients in src/lib/anchors/. No SvelteKit imports so you can copy into any project.
Pre-Built Integrations
Each implementing the shared Anchor interface with different capabilities.
SEP Protocol Library
Composable implementations of SEP-1, 6, 10, 12, 24, 31, and 38 for building against any SEP-compliant anchor.
Live Demos
Working on-ramp and off-ramp flows you can test right now with each anchor provider in sandbox mode.
How to Use It
Clone & Configure
Clone the repo and add your anchor API keys to the environment.
Try the Demos
