A technology that lets the platform cover blockchain fees (gas) on your behalf. It’s the reason you never have to pay transaction fees on PrometheX. Behind the scenes, it uses a standard called ERC-4337 to make smart contracts act as wallets.
The engine that powers trading on PrometheX. It’s a smart contract pool that automatically sets prices and lets you buy or sell shares instantly, without waiting for another person on the other side. When more people buy one outcome, its price goes up. When more people sell, its price goes down.
The blockchain network PrometheX runs on. Arbitrum is a Layer 2 — a faster, cheaper network that sits on top of Ethereum and inherits its security. Think of it as an express lane that still connects to the main highway.
A formal statement about a market’s outcome — for example, “Yes, Bitcoin did hit $100k.” The person making the assertion puts up a bond (a money deposit) to back their claim. If no one disputes it within the challenge window, it’s accepted as true.
A deposit of money that backs an assertion or dispute. If you assert an outcome and you’re right, you get your bond back. If you’re wrong, you lose it. This financial incentive keeps the system honest.
A service that moves tokens from one blockchain to another. For example, you might use a bridge to move USDC from Ethereum to Arbitrum. Think of it as a ferry between two islands.
The time period after an outcome is asserted during which anyone can dispute it. On PrometheX, this is typically 2 hours. If nobody disputes during this window, the assertion is accepted and the market settles.
The action of collecting your winnings after a market resolves. If you hold winning shares, you tap “Claim” and the smart contract sends USDC to your account. It’s free — no fees, no gas costs.
The underlying technology that represents your shares on PrometheX. Each outcome in a market is represented as a conditional token — a special type of digital token (ERC-1155) created by the Gnosis Conditional Token Framework. When you buy “Yes” shares, you’re actually receiving conditional tokens that can be redeemed for USDC if that outcome wins.
Not controlled by any single person or company. PrometheX uses decentralized smart contracts and oracles, meaning no single entity can manipulate trades, outcomes, or your funds.
A challenge filed against an asserted outcome. If someone believes the market’s result was declared incorrectly, they can dispute it by posting a counter-bond. The dispute is then resolved by an independent vote.
A fee charged by blockchain networks for processing transactions. On most crypto platforms, you pay gas fees every time you do something. PrometheX covers all gas fees for you — you never pay them.
A risk for liquidity providers. It happens when share prices in the pool move significantly from when you added funds. If one outcome becomes very likely, you might get back less than you put in. The trading fees you earn can offset this, but not always.
A network built on top of another blockchain (Layer 1) to make it faster and cheaper. Arbitrum is a Layer 2 on Ethereum. You get Ethereum-level security with much faster and cheaper transactions.
The pool of funds available for trading in a market. More liquidity means smoother trades with less price impact. Liquidity is provided by users who deposit USDC into market pools.
A token you receive when you provide liquidity. It represents your share of the pool. When you want to withdraw, you return (burn) your LP tokens and receive your USDC back plus any fees earned.
A question about a real-world event that you can trade on. For example, “Will ETH hit $5,000 by July 2026?” Each market has outcomes (like Yes and No), prices, and an end date.
A system (or person) that provides buying and selling opportunities in a market. PrometheX uses an automated market maker (the APMM) — a smart contract that always stands ready to trade with you.
A system where you control your funds, not the platform. PrometheX is non-custodial — your USDC is held in your smart account or in transparent smart contracts, never in PrometheX’s bank account.
An independent system that brings real-world information onto the blockchain. PrometheX uses the UMA Optimistic Oracle to verify market outcomes. It’s like a neutral referee that determines who won.
One of the possible results of a market question. In a binary market, the outcomes are Yes and No. Multi-outcome markets can have three or more options (like different election candidates).
Your holdings in a market — the shares you own. Your position shows what you’ve bought, how much it’s currently worth, and what your potential payout would be.
A specific conditional token representing one outcome of a market. For example, in a Yes/No market, there are two position tokens — one for Yes and one for No. Position tokens are ERC-1155 tokens identified by a unique position ID. You can hold, transfer, or redeem position tokens just like any other digital token.
A marketplace where you trade on the outcomes of real-world events. Prices reflect the crowd’s estimate of how likely each outcome is. PrometheX is a prediction market platform.
The process of determining a market’s outcome after the real-world event happens. On PrometheX, this involves an assertion, a challenge window, and (if disputed) a decentralized vote.
What you buy and sell on PrometheX. Each share represents a specific outcome in a market and is priced between $0.00 and $1.00 USDC. Winning shares pay $1.00; losing shares pay $0.
The difference between the price you expect and the price you actually get. Larger trades tend to have more slippage because they move the market price more. For most normal-sized trades, slippage is very small.
Your personal wallet on PrometheX, created automatically when you sign in. It’s a smart contract that acts as your on-chain identity. You don’t need to manage private keys or remember seed phrases — just sign in with your email or social account.
A program that runs on the blockchain and executes automatically. Smart contracts handle all trading, payouts, and fund management on PrometheX. They’re transparent (anyone can read the code) and tamper-proof (nobody can change them after deployment).
Two fundamental operations in the conditional token system. Split takes your USDC and creates a complete set of outcome tokens (e.g., one Yes token + one No token). Merge is the reverse — it takes a complete set of outcome tokens and converts them back to USDC. The APMM handles splitting and merging automatically when you trade, but advanced users can perform these operations directly.
A cryptocurrency designed to always be worth $1.00 (or another fixed value). USDC is the stablecoin used on PrometheX — each USDC token is backed by real US dollars held in reserve.
A practice version of a blockchain where tokens have no real value. PrometheX is currently on Arbitrum Sepolia testnet, which lets you try everything risk-free with free test tokens.
A small fee (typically 1%) charged on each trade. This fee goes to liquidity providers as a reward for making trading possible. PrometheX doesn’t take a cut.
The decentralized system PrometheX uses to verify market outcomes. It works by assuming assertions are correct unless someone disputes them. If there is a dispute, independent voters determine the truth. “UMA” stands for Universal Market Access.
USD Coin — a stablecoin worth $1.00, issued by Circle and backed by real US dollars. It’s the currency you use to trade on PrometheX. Think of it as digital cash.
A market that has been cancelled before resolution. When a market is voided, all outcome tokens are redeemed at equal value — for example, in a Yes/No market, both Yes and No tokens would each be worth $0.50. This ensures all traders get a fair refund regardless of their position.
A tool for holding and managing cryptocurrency. On PrometheX, your smart account is your wallet — it’s created automatically and you don’t need to install any apps or extensions. If you’re a crypto-native user, you can also connect an existing wallet like MetaMask.
