I have a legacy Bitcoin Core hash (PBKDF2-SHA512 + AES-256-CBC, 72,580 iterations, extracted March 2009) and I’d like you to attack it with your own tool-chain. You will receive nothing except the single $bitcoin$64$… string, so all dictionaries, masks and custom rules must come from your side. Your profile should show at least moderate experience recovering passwords on GPU hardware. Because the hash is computationally heavy, access to an RTX 4090 is essential, and I’ll rely on your skill with custom rule-based and mask attacks in Hashcat to make the most of that card. The job is outcome-driven: I’m open to a success-fee or staged milestones—tell me which you prefer. When you apply, include your benchmark speed for PBKDF2-SHA512 on the 4090 and outline the...

I’m rolling out a new crypto wallet and need a production-ready smart contract written for Binance Smart Chain. The contract has to handle full token management, cover all transaction handling logic, and include a built-in multi-signature layer for extra security. Here’s how I picture the collaboration: • Token management should support minting, burning, transfers, and allowances in line with the BEP-20 standard (or an equivalent custom approach if you believe a tweak would be safer or more gas-efficient). • Every critical action needs event logging so the front-end can surface real-time status updates to users. • Multi-signature approval must gate high-value actions such as owner transfers or contract upgrades. A simple n-of-m schema is fine as long as sig...

I need a developer who can take full ownership of opening, configuring, and technically integrating accounts for thirty-five separate payment providers on my e-commerce sites. All integrations will run on standard website stacks, not mobile or desktop apps, and each gateway must successfully process both credit/debit card transactions and the cryptocurrency options that the providers allow. Here’s what the job looks like from my side: I will supply access to the sites, the list of providers, and any required corporate documentation. You will handle the account applications where needed, obtain and secure API keys or SDKs, install the gateways, map the required webhooks, and make sure that successful, failed, and refunded payments are reported correctly in the site’s back-offic...

I am launching an affiliate programme that connects our all-in-one crypto wallet with high-calibre crypto influencers. The single objective is to boost day-to-day platform usage—more buys, swaps, sends and receives—by channelling the audiences of trusted voices in the space. The wallet already supports multiple coins and offers instant buy, send, swap and receive crypto. What’s needed now is a structured affiliate engine: bespoke tracking links, clear revenue shares and compelling creative that persuades followers to move their assets through us after they sign up. Key deliverables • Identify and shortlist crypto influencers whose audiences match our target regions and user profiles • Negotiate and formalise affiliate terms, including commission tiers tied...

I’m ready to launch a brand-new cryptocurrency with a fixed maximum supply of 10 billion coins and I don’t want to piggy-back on Ethereum, BSC or Polkadot—I need an independent chain built from the ground up. The core purpose of the coin is to power smart-contract execution, so the chain architecture, virtual machine and fee model all have to be optimized for that use-case. What I already have in mind • Tokenomics: 10 billion total supply, no more, no less. • A smart-contract–friendly environment that can rival EVM chains in speed and cost. • Room to evolve into DeFi utilities later on. Where I need your expertise I’m looking for end-to-end technical guidance and implementation: choosing or designing the right consensus layer, writing ...

I plan to mirror the smooth, bettor-friendly experience offers by adding a full cryptocurrency payment flow to my own platform. The core of the job is to build the back-end logic that accepts deposits in crypto, then wrap it in an interface that feels and behaves just like BetOnline’s cashier: same screen sequence, clean typography, progress indicators, and on-page confirmations. Deliverables 1. Fully working integration pushed to my server 2. Front-end pages styled and responsive 3. Setup and deployment documentation I can hand to my team 4. Post-launch support for bug fixes or minor tweaks

Every weekday I need a sharp, self-driven assistant to keep me ahead of the curve in trading, finance, crypto, and stocks. Your first task each morning is to gather the key moves, numbers, and stories shaping those markets, then condense them into a short briefing I can skim in under five minutes. Right after that, take the insight you’ve uncovered and turn it into short, punchy reel scripts (think 30–60 seconds) that deliver clear educational tips my audience can act on. I post mainly on Instagram and Twitter, so you’ll adapt the copy, hooks, and hashtags for each platform, schedule the uploads, and handle basic community interaction during the day. Daily deliverables • One concise market brief covering trading, finance, crypto, and stocks • Three to five r...

Here’s what must be in place from day one: • A truly user-friendly interface that shepherds users from account creation to their first purchase without exposing them to intimidating order books. • Educational resources integrated right into the flow—tooltips, short videos, and concise articles that answer questions in context. • Instant buy/sell functionality so a beginner can move from fiat to crypto (and back) in just a few clicks.

I am ready to move from concept to code on a new cryptocurrency that will carry a fixed supply of 10 billion coins. The token must be created directly on the Deca blockchain, using its recommended tool-chain and security guidelines. The coin’s primary use case is identified internally as “I”. I will clarify the functional details and token-economics with you once we start, but the core idea is to make the asset immediately usable within my wider ecosystem and future DeFi modules. Here’s what I need from you: • A solid, audited smart-contract that mints the full 10 billion supply, handles transfers, burns, and all standard compliance events. • Deployment of that contract to Deca mainnet, plus a testnet version for validation. • A concise te...

I need a secure, web-based platform that lets me log in and watch Binance, Coinbase and Kraken and more simultaneously. The system must stream live order-book data and weave together volume, open interest, incoming-versus-outgoing flows and liquidity levels into a single proprietary indicator that updates in real time and shows bias based on bullish / bearish sentiment. A clean dashboard with time-series charts, heat maps and quick-filter controls should make it easy to spot shifts in market pressure at a glance. When any metric hits a value I define, I want the option to turn on notifications and choose whether the alert is sent by email or SMS; switching alerts on or off must be possible from inside the app. Core deliverables: • API connectors for Binance, Coinbase, Kraken with...
