Why I'm building this
Most of my blockchain exposure has come from the product side — Open Finance rails, KYC, and a marketplace that included crypto products at MiBolsillo. StableFlow is one level deeper: actually moving value across a fiat-on-ramp → USDC → blockchain → fiat-off-ramp path myself, rather than only having managed products that touched it.
The scenario: a Brazilian freelancer receives US$1,000 from a US client in USDC, holds it as digital dollars, and later converts part of it to BRL.
What it demonstrates
- The full transaction lifecycle: on-ramp, wallet custody, a real testnet blockchain transaction, off-ramp, and FX.
- The failure states that actually matter in this flow — insufficient balance, wrong network, KYC gating, off-ramp unavailability, depeg risk — and why each needs to be caught before authorization, not after.
- An honest comparison between stablecoin and traditional cross-border rails, including where stablecoins don't automatically win: fees, liquidity, and off-ramp availability still depend on the specific corridor.
Where it stands
This project is in progress. The full write-up — architecture diagram, testnet transaction hash, failure-state documentation, and rail comparison — will replace this page once it's built.
