I'm building AuthOnce — non-custodial subscription payments on Base. Here's what that means: → Merchants create recurring billing plans on-chain → Subscribers authorize once, never think about it again → Funds go subscriber → merchant atomically. Protocol never touches them. → 0.5% flat fee. No chargebacks. No custodian licence needed. Solo founder. Day job in Switzerland. Building evenings & weekends. Mainnet Q3 2026. authonce.io | @AuthOnce

Something I didn't expect when building AuthOnce: The subscriber experience in Web3 payments is basically an afterthought. Every protocol I studied was built for the merchant. The subscriber just had to trust nobody would drain their wallet. That's not good enough. #DeFi #Base #Web3

Subvisual call Monday. First real conversation with people who've built and scaled Web3 products. Solo founder preparing for his first investor meeting. No pressure. Building in public means sharing this too. #BuildInPublic #Web3 #Fundraising

The hardest part of building a payment protocol isn't the payments. It's the failure layer. What happens when a payment fails at 3am? Who gets notified? How many retries? When do you give up? Grace periods, keeper bots, webhook fallbacks — that's the real product. #BuildInPublic #DeFi #Base

6 months ago I didn't know Solidity. Today I have a smart contract running 24/7 on Base Sepolia processing test subscriptions. No co-founder. No team. Day job in Switzerland. This is what evenings and weekends look like. #BuildInPublic #Base #Web3‌‌

Why non-custodial matters for subscriptions: If the protocol holds your funds — even for a millisecond — it needs a licence. AuthOnce never holds funds. One atomic tx: subscriber wallet → merchant wallet. That's not a feature. It's the legal foundation. #DeFi #Base #Web3‌‌

Built a white-label crypto subscription checkout. The merchant brands it completely. Subscriber sees their product, their price, their domain. @AuthOnce handles the USDC payment layer underneath. One authorization. Automatic pulls. Testnet live on Base. Mainnet September 2026.

Authorize once. Your subscribers pay forever — automatically, on-chain, from their own vault. No passwords. No card details. No merchant ever touches a single USDC. This is what subscription infrastructure looks like when you build it right. @buildonbase @authonce

Just launched @AuthOnce — recurring payments on Base. Follow along. 🧵 coming soon.

Just deployed two smart contracts on Base Sepolia for AuthOnce — non-custodial recurring payments. 0.5% fee. No chargebacks. Credit card onramp. Live at authonce.io @base @buildonbase #BuildOnBase @AuthOnce
