Relaycode makes building Polkadot transactions feel human. A dual-pane interface keeps readable inputs on one side and the SCALE-encoded hex on the other — pick a chain, pick a pallet, fill in parameters with more than twenty type-aware input components, sign with your wallet.
The grant
The Web3 Foundation funded Relaycode through its grants program — the application was merged in October 2024, and Milestone 2 (type-aware components, wallet integration, production UX) was delivered in February 2026. It's built on Dedot, the modern Polkadot SDK, rather than the legacy API.
The longer story
Relaycode is also a redemption arc. Years earlier I took a Kusama treasury grant for the same idea — Extrinsics.io — and didn't finish it. Instead of letting that sit, I rebuilt the concept from scratch, applied for W3F backing under a new name, and delivered. The accountability post for the original grant is part of the plan, not a secret.
Relaycode also spawned Relaycode Studio — a smart contract IDE for Polkadot Hub that took 1st place in the EVM track at the Polkadot Solidity Hackathon (OpenGuild × Web3 Foundation) and got quoted by the official Polkadot account. My Web3 work — Relaycode, the Wisesama anti-scam platform it integrates with, wins at Polkadot Prodigy ($6,000) and CTRL Hack ZK ($2,300) — lives here on my personal profile, separate from the studio.
