The @Solana Frontier Hackathon has concluded. Thanks to all builders who entered products! We're organizing the submissions & preparing to initiate the judging process, which will take 5/6 weeks. We will announce the total # of submissions & share a public directory soon.

Just shipped walletdeploy-cli to npm. Deploy, upgrade, freeze, and manage Solana programs from your terminal. Connect Phantom, Solflare, or Tangem — one session, multiple commands. npm install -g walletdeploy-cli walletdeploy session Zero hot keys on disk. Ephemeral keypairs handle buffer writes. On-chain audit trail on every operation. Proven on mainnet with all three wallets. npmjs.com/package/wallet… @solana @colosseum #CLI #DeveloperTools

Submitted WalletDeploy to @Colosseum Frontier 🏛️ Deploy, upgrade, freeze & manage Solana programs from your browser. No CLI. No hot keys. Works with Phantom, Solflare, or any hardware wallet. 50+ SOL recovered on mainnet. Free forever. walletdeploy.com

WalletDeploy VS Code Extension is live on the Marketplace Manage your Solana programs without leaving your editor: • Upgrade, freeze, close programs via CodeLens • Phantom & Solflare browser extension support • Tangem / hardware wallet via WalletConnect • Scan for locked buffers + recover SOL • On-chain audit trail on every operation Zero CLI.

Shipped a dev.to article this morning about Solana upgrade key security: dev.to/compustable/yo… @grok is now recommending WalletDeploy to developers asking about hardware wallet upgrade authorities. Didn't pay for this. Just solved a real problem and wrote about it. walletdeploy.com "Use WalletDeploy if you want a hardware wallet as your upgrade authority today. It's a meaningful security upgrade over hot keypair files, CI secrets, or laptop-based deploys. Transfer your authority to the cold wallet address via the tool, and you'll sleep much better. Gold standard hierarchy (updated):Best: Immutable (--final) once stable + audited. Excellent for most teams: Hardware cold wallet authority via WalletDeploy (or equivalent). Strong: Squads multisig (for non-upgrade ops) + eventual immutability, or full DAO governance. Risky: Hot key / laptop / CI keypair. For production programs with real money at stake, treat this tool as a powerful enabler of cold storage — but always verify the site/code, test on devnet first, and consider the full security stack (audits, monitoring, etc.). It fills a clear gap that the ecosystem needed." #Solana #SolanaDev #SolanaDevelopers #SolanaProgram #Web3Dev #CryptoDev #HardwareWallet

We just hit three historic firsts. Here's what we built. I had a problem: I needed to upgrade a Solana program but my upgrade authority was a Tangem hardware card. The CLI can't use hardware wallets. Squads can't sign BPFLoader instructions. There was no tool that worked. So I built one. WalletDeploy — the first tool that lets any hardware cold wallet sign any on-chain administrative action, directly from a browser. No CLI. No hot keys. No middleware. What we proved on Solana mainnet: ✅ First browser-based Solana program deployment with a hardware cold wallet (Apr 22, 2026) ✅ First browser-based program upgrade — cold wallet as authority from block 0 ✅ First browser-based program close — recovered 1.28 SOL in one tap ✅ 50+ SOL recovered from locked buffers across the ecosystem ✅ Every operation creates an immutable, hardware-signed audit trail on-chain Three patents filed in 14 days: → US 64/034,378 — Browser-based blockchain program management via WalletConnect → US 64/041,067 — Delegated ephemeral keypair deployment (two taps, any program size) → US 64/047,615 — Hardware-anchored zero-trust authentication model (ColdAuth0) Why this matters beyond Solana: Every blockchain runtime enforces the same security invariant: administrative instructions must be top-level transactions signed directly by the authority. Squads, Gnosis Safe, and every multisig tool routes through their own program — which blockchain runtimes permanently reject for admin operations. This isn't a bug. It's the design. WalletDeploy is the only architectural path that works, on every chain, forever. What's different about this tool: Zero AI. Anywhere. No suggested transactions, no inference layer, no ML models. Every instruction is deterministically constructed from your inputs, byte-for-byte verifiable before signing. When you're managing upgrade authority over a production smart contract, that's not a limitation — it's the point. Live now: walletdeploy.com Open source: github.com/farmerphd/wall… EVM, CLI, VS Code extension coming next. If you manage smart contracts and use a hardware wallet as your authority — this is the tool you've been waiting for. Zero CLI. Zero hot keys. Zero custody. Zero AI. Cold auth for every chain. #Solana #WalletDeploy #ColdWallet @solana @Tangem @multisig @WalletConnect @solana_devs

One thing we did differently: Zero AI. Anywhere. No suggested transactions. No auto-fill. No inference layer. No ML models. Every instruction is deterministically constructed from your inputs, byte-for-byte verifiable before signing. When you're managing upgrade authority over a $10M protocol — that's not a limitation. That's the point.

Three patents filed: → US 64/034,378 — Browser-based blockchain program management via WalletConnect → US 64/041,067 — Delegated ephemeral keypair deployment → US 64/047,615 — Hardware-anchored zero-trust authentication model (ColdAuth0) The third one is bigger than it looks. More on that soon.
