Finally submitted! I built Forge, a trustless freelance marketplace on Solana that turns completed work into permanent on-chain identity. With Forge your wallet becomes your resume, built from verified, on-chain work history that no platform can take away @colosseum @superteam

I've been building for the @SuperteamNG Advanced Infrastructure bounty, and the most interesting part has been moving beyond the usual “submit tx poll RPC” flow. The stack I’m using: - @SolinfraDev RPC for reliablemainnet access - Yellowstone gRPC for live slot / network streaming - Jito Block Engine for priority-aware transaction submission - Rust for the transaction engine and lifecycle tracker - Next.js for the operator surface - Groq for low-latency AI-assisted infra decisions The biggest lesson: once you start working with streamed network data, transaction submission feels very different. Instead of treating confirmation as a black box, you can reason about: - observed submit slot - dynamic tip selection - block engine response - bundle / signature lifecycle - processed -> confirmed -> finalized progression - failure classification - retry strategy - latency between stages Jito also makes it obvious that “fee” is not just a static number. Tip selection becomes an operational decision that depends on current network conditions, recent outcomes, and risk tolerance. Still keeping the actual build private until submission, but this bounty has been a serious deep dive into what a smarter Solana transaction stack should look like. #Solana #BuildInPublic

@BybitAfrica @Bybit_Official I made a transaction of about 430 solana:2u1tszSeqZ3qBWF3uNGPFc8TzMk2tdiwknnRMWGWjGWH to pay for something I needed some months ago. The vendor didn't inform me that solana:2u1tszSeqZ3qBWF3uNGPFc8TzMk2tdiwknnRMWGWjGWH is not supported so neither of us can access the funds, what can I do? We reached out to customer support but got nothing so far. This is the transaction signature, 34zDBMdYzhqiyvuTgXAobJsYtYX6XukfELRtmoXbgEuxSqfn1NsZrZtt6ht9C2tfVAhmoEGMyUdSomAzBBUbfYUS

This scene genuinely altered my brain chemistry. The way he stumbles back from the railing, completely stunned. The way he rushes down the stairs without even looking where he's going. The disbelief on his face when he realizes she's really standing there. And then that embrace... 😭 After years apart, finally seeing family again. It shattered my heart and put it back together in the same moment.

Elon Musk is officially the first trillionaire in human history.

Three years ago, Solana had little to no presence in Africa’s largest crypto economy 🌍 Today, dozens of global ecosystem teams have expanded into Nigeria with our support, hundreds of leading regional products have integrated Solana with our help, and thousands of Nigerians have earned, built products, landed jobs, won hackathons, raised early-stage capital, and found their place in the global Solana ecosystem through this community 💪🏿 And it still feels like we’re just getting started 🥳 Happy 3rd anniversary to everyone building with us 🫡

Wins, failures, and everything in between, no filter. Follow along.

#Sponsored / #LedgerSponsor I built a Ledger-gated Solana treasury agent for the @Ledger Agent Stack bounty. An AI agent can understand intent. An app can construct a transaction, but neither should automatically get the final say over moving value. So I built a small treasury agent where the user can type “send 0.2 SOL to <address>”, then the app parses that into a structured action, builds a Solana devnet transfer, and routes the signing step through Ledger’s signing flow using Speculos, Ledger’s open-source device emulator. The flow: User command -> AI intent parser -> Solana transaction builder -> Ledger Solana app through Speculos -> manual review on the device screen -> user approves “Sign transaction” -> signed transaction broadcasts to devnet Repo: github.com/SamuelOluwayomi/L… Why I think this matters: Most agent demos still treat private keys like normal app secrets. Put the key in an .env file. Let the backend sign. Trust the model, prompt, server, dependencies, and runtime. That is fine for toy demos. It gets uncomfortable when the agent can touch real assets. .env secrets are copyable. API keys leak. Servers get compromised. Prompt injections happen. Dependencies break trust assumptions. Lately we've been hearing about hackers adding malware to popular libraries, users install and then they access important data. I myself was a victim of something similar, my wallet seed phrase was gotten unbeknownst to me and all my crypto was drained. The architecture I wanted to test was different: The agent is a participant, not a custodian. It can propose an action. It can build a transaction. It can explain what it wants to do. But the signing boundary sits outside the agent runtime. In my build, the private key never enters the Node server, the Groq call, the React app, or the prompt context. The final approval happens on the Ledger-style review screen in Speculos. That is the interesting part of Ledger’s Agent Stack to me. Not “hardware wallet, but for agents.” More like: Agent infrastructure needs a physical policy boundary. Software is great at generating intent. Hardware is better at enforcing final consent. The critical take: This does not magically make agents safe. A Ledger-gated flow does not fix bad transaction construction, malicious frontends, confusing UX, weak policy design, or users approving things they do not understand. If the review screen is vague, the guardrail is weaker. If the app hides intent, the user can still make a bad approval. If the agent builds the wrong transaction, the hardware layer only helps if the user can actually inspect what matters. So the hard problem is not just “add signing.” The hard problem is making the transaction review legible enough that a human can make a real decision at the boundary. That said, this architecture feels like the right direction. Agents are getting better at action. That means we need better limits around action. Ledger’s Agent Stack gives builders open primitives for that: DMK Skills: app/device integration for agent-readable signing flows Wallet CLI: agent-friendly transaction flow from terminal to device approval Enterprise CLI: policy-backed enterprise flows Multisig CLI: treasury and scheduled workflow patterns where signing still ends at a Ledger device For this project I focused on DMK-style integration with Speculos because I wanted the signing flow inside my own app, not just a standalone CLI demo. Speculos was especially useful because I do not need a physical Ledger device to prove the architecture. It reproduces the screen and signing flow, so the demo still shows the important thing: the agent cannot complete the transaction until the device flow returns a signature. That is the layer I think agentic crypto apps are missing. Not more autonomy by default. More explicit boundaries around autonomy.

Oh wow, how come I didn't think of this

🚨 EVERYTHING THAT COULD GO WRONG FOR MARKETS WENT WRONG TODAY. S&P 500 down -1.65%, wiping out $1.14 trillion. Nasdaq down -2.60%, wiping out $1.11 trillion. Gold down -3.38%, wiping out $1 trillion. Silver down -6.9%, wiping out $280 billion. Bitcoin down -6.31%, wiping out $80 billion. In total $2.5 TRILLION wiped out in a single session. These were not isolated moves. Everything started breaking at the same time. It started with the jobs report this morning. The US economy added 172,000 jobs in May. Wall Street expected 88,000. That is almost double. On any normal day, strong jobs is good news. But inflation is already at 3.8% and oil is sitting at $90. A labor market this strong tells the Fed it cannot cut interest rates and may actually need to raise them. The probability of a rate hike this year went from 40% to 57% in a single day. That spooked every investor holding tech and growth stocks because higher rates mean those stocks are worth less today. Then the AI trade started cracking. Yesterday Broadcom reported record earnings: revenue up 48%, AI chip sales up 143% and the stock still crashed 12.6%. The reason was simple. Broadcom did not raise its AI revenue targets for the year. Investors had expected it to. That single miss made people ask a question they had been avoiding for months: are we paying too much for AI stocks? That question got louder today when a research firm called SemiAnalysis revealed that Nvidia's next-generation AI chips will need significantly less memory than everyone assumed, roughly half of what the market was pricing in. Memory chips are what companies like SK Hynix and Samsung make. SK Hynix fell nearly 10% today. Samsung fell over 6%. South Korea's entire stock market crashed 5.5% in a single session. Japan's semiconductor stocks did the same. And then Anthropic added fuel to the fire by publishing a report warning that AI is getting close to the point where it can improve itself without human help and calling for a global pause in AI development. Coming on the same day as the memory demand news and Broadcom's miss, it fed a single growing fear across the market: what if the AI boom is moving faster than the business models can keep up with? Underneath all of this, there is a liquidity problem nobody is talking about. SpaceX goes public next week at a $1.75 trillion valuation. Anthropic just filed to go public. OpenAI is next. These three companies together are worth $4 to $5 trillion. Fund managers need cash to buy into these listings. But cash levels are already at their lowest since early 2024. The only way to raise cash is to sell what they already own. That selling is happening right now. The new Fed Chair Kevin Warsh will also hold his very first policy meeting in 11 days. He was appointed by Trump with the expectation of cutting rates. He is now walking into a situation where inflation is high, oil is high, and the job market is running hot. Investors do not know what he will do. When nobody knows what the most powerful central banker in the world will decide in less than two weeks, the safest move is to reduce risk today. Everything that could go wrong, went wrong at the same time. A hot jobs report, a collapsing ceasefire, a crack in the AI trade, a trillion dollar liquidity drain, and a Fed meeting with no clear outcome.

Stay strong guys, hold your positions... DO NOT SELL!!
