...autonomous agents won't know how to "talk" to your code or how to pay you. 2. The "Phonebook" (The Almanac) When you run the script, your agent "signs in" to the Almanac. What it does: The Almanac is a decentralized directory on the ASI blockchain. The Simplified Flow: Your script generates a unique ASI Wallet Address. It sends a "heartbeat" to the network. The network lists you under the "Compliance" and "Security" categories. 3. The "Storefront" (The Deck Deploy) The final step (deck deploy) is the bridge between the blockchain and the "normal" internet. The Hub: It hosts your code so it stays online 24/7. The Spokes: It automatically creates "For Sale" listings on Ra...

I need a small server-side application that reads a .FIN file, extracts the M0 and M1 fiat balances it contains, converts those balances to USDC/USDT at the current rate, and routes the settlement through Blockchain. Here’s what matters most to me: • Codebase in Python. Please keep the structure clean, modular, and ready for unit tests so future maintenance is painless. • Direct integration with Circle Mint and Tether for issuing and redeeming USDC/USDT. If Circle’s API is temporarily unavailable we can discuss a fallback—Tether’s own API or an exchange gateway like Kraken—but Circle Mint is the primary path. • Accurate parsing of the .FIN format. The file can hold multiple currency rows, so the parser must detect fiat type, pull ...

I am ready to take a theta-based trading idea from whiteboard to production and need a Web3 full-stack partner to carry the build end-to-end. The core features are already defined: real-time trading data flowing into the interface and automated trading algorithms executing on-chain. Everything will run on the Theta blockchain, so familiarity with Theta SDK, solidity-style smart contracts, and its RPC infrastructure is essential. Authentication will be wallet-based (e.g., WalletConnect or a custom Theta wallet integration) so users can sign transactions directly without traditional log-ins. Here is what I expect to see completed: • Responsive front-end (React/TypeScript preferred) that streams live market data and presents intuitive trade controls. • Smart contracts on...

I want to launch a brand-new crypto coin on its own custom blockchain, then build out everything needed for people to actually use it. The work begins with the chain itself: consensus design, node software, smart-contract capability, a block explorer, and clear tokenomics that leave me free to adjust supply or governance later on. Once the chain is live, I need a companion wallet / exchange app that runs smoothly on iOS, Android, and the Web. Users must be able to store, send, receive, trade, and convert the coin in-app, with security features such as biometric login, 2-factor authentication, and optional cold-storage integration. Finally, the coin has to power in-game purchases inside a first-person-shooter that also offers a lighter casual mode. Think weapon skins, character upg...

I already have an Expo project started and need an experienced React Native developer to finish the front-end for a small, fully local crypto-exchange mock-up. The work is strictly UI—no server calls, no blockchain integration—everything is stored on the device. Scope of the remaining work • Complete three screens: Home Dashboard, Buy/Sell, and Portfolio, wired together with React Navigation. • Add a lightweight security gate: a 4-digit PIN code set on first launch and validated on every app open (SecureStore or similar local option is fine). • Implement the layout exactly as in the Figma design reference I’ll share; responsiveness on common phone sizes is essential. • Persist mock portfolio data, recent trades, and the user’s PIN...

Echo Sports Predictive Network is the world's first sports intelligence progression economy. Fans earn $ECH utility tokens on the Solana blockchain for demonstrating sports knowledge — designed for redemption across real-world rewards, event experiences, boost promotions, and NFT achievement certificates, subject to partner agreement execution. Unlike betting or gambling platforms, Echo Sports users never wager money and never lose tokens they already hold. The platform operates on a zero-loss model: incorrect predictions do not reduce a user's wallet balance — they simply earn less, with 20% of potential earnings redirected as a deflationary burn to the Echo Foundation treasury. Echo Sports is not a prediction market. Not a betting app. Not a fantasy sports pl...

I’m building a next-generation real-estate platform that anchors physical property rights on-chain. Before we push further, I need a senior blockchain professional who can sit with me, review what we have, and help craft the smartest possible smart-contract layer. The conversation will revolve primarily around smart contract development—especially the functional design of a robust property-tokenization module. I already have early Solidity prototypes, an outline of how tokenized deeds should flow through the platform, and a clear picture of the user journey; what’s missing is the seasoned perspective that catches edge cases, foresees scaling hurdles, and shapes an elegant contract architecture from day one. You will: • Walk through the current repo (Solidit...

...certificate has not been tampered with. Only the hash ever leaves the user’s machine; the document itself stays off-chain. The flow I have in mind: 1. User opens the React front-end (MetaMask connected). 2. They drag-and-drop a certificate (PDF, image, or any common format). 3. The app calculates a SHA-256 hash, sends it to a Solidity contract, and the contract records it immutably on the blockchain (local Ganache during development, then a public testnet or mainnet). 4. To verify, another user re-uploads the certificate; the app re-hashes it and checks the smart contract for a match, instantly confirming authenticity. Technologies I expect you to use include Ethereum + Solidity for the contract layer, React/HTML-CSS-JS for the front-end, and either Node.js or...
