About
OneSet is a session-based trading and prediction application that enables instant, gasless user and AI-agent interactions off-chain, with secure on-chain settlement only once at the end of a session. Built using Yellow Network, Uniswap v4, and LI.FI, OneSet delivers Web2-like speed while preserving Web3 security and verifiability. Problem Modern on-chain trading and prediction apps suffer from fundamental UX and cost issues: - Every interaction requires a blockchain transaction - High gas fees make micro-transactions impractical - Latency breaks real-time trading and agent-driven strategies - AI agents cannot safely execute frequent actions on-chain As a result, many high-frequency or session-based financial interactions are either impossible or economically inefficient on-chain. Solution OneSet introduces a session-based model for DeFi interactions: - Users deposit funds once - Perform unlimited instant actions off-chain (trades, predictions, agent execution) - Settle the net result on-chain only once when the session ends This approach dramatically reduces gas costs, improves UX, and enables entirely new classes of applications such as AI-driven trading and micro-markets.
How it's made
So for the frontend we use Next Js with TypeScript, the Smart Contracts are deployed on Arbitrum. We use Yellow’s state channels and session keys to: - Enable real-time, gasless interactions - Support session-based spending limits - Secure off-chain balances with cryptographic guarantees - Compress dozens of actions into a single on-chain settlement Uniswap v4 is used for final execution and price discovery, not for every interaction. Trades are simulated and netted off-chain during a session Agentic Finance - AI agents make decisions off-chain in real time Hooks are used to enforce: - Slippage limits - Risk constraints - Execution conditions - Execution remains transparent, verifiable, and safe Using LI.FI, we enable: - Deposits from any EVM chain - Swap + bridge + deposit in a single flow - Seamless capital movement for users and AI agents
