MonoLock

MonoLock is a trustless escrow platform built on Monad. It lets two parties complete a deal, freelance work, a marketplace sale, or any peer-to-peer trade without needing a centralized platform to hold funds or arbitrate disputes. What it does: A buyer deposits funds (native MON or an ERC-20 stablecoin) into a smart contract, specifying the seller and an auto-release date. If nothing goes wrong, the seller can claim the funds themselves the moment the deadline passes, fully permissionless, no admin involved. If either party runs into a problem, they can raise a dispute before that deadline, freezing the auto-release. From there, either side can propose a split (e.g., 60% back to the buyer, 40% to the seller), and funds only move once the other party accepts, enforced entirely by the contract, not by trust. Why Monad: the near-instant block times and low fees make escrow practical for smaller, everyday transactions that wouldn't make sense on slower or more expensive chains, not just big-ticket deals. What I learned: building on an EVM-compatible L1 meant standard Solidity patterns (OpenZeppelin's ReentrancyGuard, checks-effects-interactions) carried over directly, but I learned a lot about designing dispute-resolution logic that's fair without needing a centralized arbitrator, and about the UX side of Web3, making wallet connection, network switching, and contract interaction feel simple for non-technical users rather than requiring them to touch a block explorer or raw transaction data.
