Ari (@AriEiberman) is a consultant who runs his business on stablecoins. When clients wanted to pay by wire, he turned them down, and lost work because of it. A neobank virtual account didn't fix it either: one payment sat frozen for two weeks while the provider asked him for more banking details.
With Suby, Ari's clients pay however they want, by card or crypto, and Ari gets paid in the stablecoin he wants, within two days. No more turning clients away. It runs on @arc because settling in USDC onchain means no bank in the middle holding payments up, and Ari knows when his money lands. Live on Arc mainnet.
We're excited to share that Suby has been selected as a Circle Developer Grant recipient.

Suby is officially part of the @circle Alliance.
When we started building Suby on @USDC, we had one goal: let your customers pay with the methods they already use, while you withdraw in stablecoins.
Months later, that work earned us our place.
EURC is live, @arc is next, and we're building it alongside the Circle team.

We're not doing this alone.
We already work with @usaibis, and @AriEiberman is helping us sharpen both the product and our offer for this market, grounded in real feedback from LatAm operators.

Settlement: where does the money go?
Two modes:
→ Suby balance: converted and credited as USDC (powered by @lifiprotocol) or USD, sitting right next to your card and Apple Pay revenue. One dashboard, one payout flow.
→ Your own wallet: funds go straight to your wallet, no Suby balance involved.
