Say hi to Salu now on @MiniPay.

@hisaluto es mi primer app 100% desarrollada con IA en pasar los 5.000 usuarios en un día gracias a ser listada como miniapp en @minipay (+19 millones de wallet activas) 🤯

distribution is everything @Celo @CeloDevs

[Artu Grande @ArtuGrande]

@hisaluto JUST PASSED 2,250 USERS IN A SINGLE DAY.

And it’s officially the app I’ve built that has reached the most users in my life.

My last 2 months as DevRel at @Celo and @CeloDevs have had a strong focus on building mini apps and developer tooling in-house.

@hisaluto has, without a doubt, been the most challenging product I’ve ever built.

An English-learning app inside @MiniPay, designed to be sustainable from day one.

A bit of the stack:

• Self-hosted voice AI, so the economics work at micropayment scale

• On-chain payment verification without a smart contract: stablecoin transfers to the treasury, validated server-side using recipient + amount + sender + double-spend protection

• 4 stablecoins (USDC / USDT / USAT / USDm), with decimals handled on-chain and gasless transactions inside minipay

• An incentive engine that never pays twice: reserve → broadcast → confirm, with nonce + locks and a needs_review state for ambiguous transactions

• Wallet as identity: no signup, no KYC

Micropayments → MRR.

The whole system is designed to scale, using Fastify + Postgres + Redis, with E2E tests running against a Celo fork in CI.

And soon, it will be available to 18M+ MiniPay users.

Huge team effort with:

@benibauer3 @SZapelao @GigaHierz @viral_sangani

2,250 users in one day is just the beginning.

More #BuildInPublic content from this mini app coming soon. 🛠️
