Recurring donations, finally automated
Sustainable funding for open source. Monthly USDC donations on Solana. Non-custodial, transparent, and automated. Add a badge, receive recurring revenue forever.
The Problem
Open source powers the world. Maintainers power open source. Funding? Still broken.
Sustainable funding is a myth
Your open source project has 10K stars but $0 in monthly recurring revenue. One-time donations spike and vanish. No predictability. No stability. Just hope.
Traditional platforms extract rent
Patreon takes 5-12%. GitHub Sponsors requires manual renewals. Supporters forget, revenue drops. You're chasing donations instead of building.
Web3 solutions are fragmented
Ethereum gas fees eat small donations. Existing Web3 platforms are custodial (your funds, their risk) or require manual approvals every month. Friction kills generosity.
How It Works
Four steps to sustainable open source funding.
Connect Wallet
Connect your Solana wallet (Phantom, Backpack, etc.). Authorize Tributary as delegate for USDC. One-time setup.
Select Repository
Choose the GitHub project you want to support. Any public repo works.
Get Your Badge
Add a contribute.so badge to your README or profile. Supporters click, subscribe, and donations flow automatically every month.
Transparent Donations
Every donation recorded on-chain. Verifiable, auditable, immutable. Supporters see their impact. You see your revenue.
Why contribute.so
Web2 simplicity, Web3 sovereignty. The best of both worlds.
Recurring USDC Donations

Why Non-Custodial Matters
Your supporters' funds, their control
Traditional platforms hold funds. They can freeze accounts, delay payouts, or disappear. contribute.so uses token delegation—funds stay in supporters' wallets until the moment of payment. No intermediaries. No trust required. Full sovereignty.
