Beyond Gno

Greffon

Greffon turns any machine into a greffer: a VPS, a Mac mini, a Windows PC, a Raspberry Pi or a NAS that runs your own apps. You pick from 24 open-source apps (Plausible, Ghost, Nextcloud, Vaultwarden and more), and Greffon handles TLS, routing and config. Your data stays on your hardware, and self-hosting is free with no feature gating.

I work across the stack:

• greffer: the worker node that deploys each app with Docker behind TLS (Python, FastAPI; AGPL v3).
• The manager: the control plane and its web app (AGPL v3, source published at launch).
• greffon-catalog: the app catalog and the CI that validates it (Apache 2.0).

ino.cash

ino.cash is an OTC desk for the CFA franc zone. People buy and sell USDT, USDC, BTC and ETH against CFA francs (XOF) with Wave, Orange Money or Pi (BCEAO), in all 8 UEMOA countries, at a rate locked for 10 minutes. Delivery takes under 10 minutes on average, on TRON, Solana, Base, Aptos, Ethereum or Bitcoin, and a white-label API for businesses is in private beta.

Okay Relay

Okay Relay is cross-chain message relaying as a service, built on Wormhole, so dApps don't have to run their own relayers. It won $4,000 in Moonbeam's "Use a GMP Protocol to Remotely Call a Contract" bounty at ETHDenver 2023.

Also

• Go runtime: softfloat64 add/sub fix (June 2026). The same fix landed in Gno as #5818.
• React: 4 merged PRs to React DevTools in 2020. Iframe support in the browser extension (#19827, #19854), symbols shown as state keys (#19786), and a crash fix when inspecting document.all (#19619).
• All in Bits: wallet UI for dither.chat (3 merged PRs, 2025).
