Time for an update. In four months my card stack went from 39 to 68 cards. And these stats are what really matter:

- 7 are fiat vs 61 are stablecoins
- 26 are custodians vs 42 are self-custody (I’m the only one allowed to move funds)
- 18 are Mastercard vs 50 are Visa
- 61 are still valid vs 7 which closed down
- I have spent $2,067 in total
- 63 have balances below $2
- ~$204 it’s how much revenue it generated to issuers like Rain, Wirex, Bridge, GnosisPay
- ~$179 it’s how much revenue I generated to KYC software like Sumsub, Persona, Veriff, etc.
- 2 have Fútbol related designs
- 4 have Crypto related designs

I test stablecoin flows, crypto cards, payments, on/offramps & wallets like it’s my day job… because it is.
If you’re building for LATAM, I want to try what you’re shipping.

Let’s GTM with onchain banking.

It’s quite cool watching projects that don’t need the crypto slang to give users blockchain capabilities, starting for the first one:
Own your money.

we are now a $100k projected ARR startup considering the last 30 days performance.

first week of november started strong: on the 8th we already did 46% of october's volume, projecting $1M volume for this month, targeting a new ath.

we also have reached a new record on the TVL for our savings account reserva: ~$23k are now earning 13.65% APY with the @norafinancexyz BRS local stablecoin.

it took us 144 days to reach our first $1M, it took 13 days to reach $1.4M, we are very proud of our GTM and distribution strategy.

the video that you see fixed on this posts is the best solution we found so far to tell the world what's going on in Brazil and why @contavcbr is so relevant to real world people. (shoutout to @athcamera @Frame_tailor_ @validotxyz directors and producers)

to all quants around: all the data in the video can be checked on brazil's central bank portal, with full disclosure.

self custody solves a huge problem of leverage that brazilians are facing on their relationship with the banks that serves them. however, self custody is too complex for the average brazilian.

the game we're playing with conta is a game of abstraction and distribution, we've been building our own stack to deliver the most simple, easy to use, mom's favorite crypto app that doesn't sound, look or works as crypto at all.

building a current account onchain is the solution we found so far to how to serve millions of brazilians that need to get the ownership of their own income back again.

we've lived this problem. we're not stopping.

conta is being prepared to be the company with the larger sum of current accounts in brazil for the next years ahead.

for this to be real, we had to start migrating our infrastructure and pushing several backend updates to move from being able to acquire 1.000 users a week (that happened 2 weeks ago), to acquire 100.000 a week not breaking.

other fundamental part of our infra is being able to develop redundancy across the main bottlenecks, the most important of them: providers.

we've been working closely to our providers @hodle_app @woovibr and @PodsFinance to design operations in new ways that allow transactions to be safer, faster and always go through.

with the recent improvement of liquidity from @norafinancexyz in their @aeroxyz pool, we are now capable of transactioning bigger volumes, with less costs and faster.

conta starts now a new phase with the announcement of its seed round on nov-18th in nyc.

if you've been following our progress, want to have access to the deck or come to @base demoday next week, please reach out. angels and vcs welcome.

also as a last, not least, note: this week we had the chance to join calls with amazing people to talk and hear them on the market, tech and our business.

a huge shoutout to @jessepollak @RonaldTato @BronheimDaniel @pat_goodridge @sserrano44 @MikeSilagadze for their time and feedbacks.

we keep building. in the arena.

Let me know if I understand it:
- AI is doing interviews now
👇
- devs multi-employed, code and audit with AI
👇
- largest hack in history because of a Binance engineer overlooked a repo from an AI interview,
👇
- Democrats win the mid terms to control the AI interviews that hacks crypto exchanges
👇
- Trump supporter’s President of Paraguay resigns after midterm while a large bank (he owns 1% of it) gets shut down for insolvency for making shady money loops…
👇
because he can’t get his crypto from Binance…?

Pizza paid with stablecoin.
No card. No visa

Just authentic peer-to-peer transa…. Who am I lying to…?

Stablecoin adoption is still not viable at merchant level. The closest we have gotten in 2026 was:
- USD/EUR Stablecoin balance accepted by intermediaries settling in local fiat
- Card programs with 3-5 middlemen to make your Stablecoin spendable.
- RTP rails with 1-2 middle men to make your Stablecoin spendable.

Still feels like a successful year.

BTW, I ordered one extra slice. Who wants to join in?
