About

OBSIDEUM is a portfolio-first trading platform. Not just another swap interface. A complete self-custody experience. You connect your wallet and immediately see your total balance across every chain, with the assets you hold pinned to the top automatically. From there you can swap any token, send to any address or ENS name, or receive on any of the 8 supported networks. Token discovery is fully automatic. When you switch chains, the top tokens surface themselves from Uniswap V3 liquidity data. The design is intentional. Every pixel. A custom WebGL visual engine, a glass design system. It looks like a product someone spent serious money on. It runs entirely in the browser. No backend. No server. Just the user and the chain.

How it's made

Swap engine: direct on-chain via Uniswap V3. QuoterV2 probes three fee tiers in parallel and picks the best output automatically. If no direct pool exists it routes through WETH or USDC as an intermediary. Execution through SwapRouter02 with standard ERC-20 approval. No fees taken. Prices and token discovery: Uniswap V3 Subgraph via The Graph across 8 networks: Ethereum, Arbitrum One, Base, Optimism, Polygon, BNB Chain, Avalanche, Unichain. The subgraph surfaces top tokens by TVL per chain and user balances are detected automatically via balanceOf calls. Wallet: Privy handles everything. injected wallets (MetaMask, Brave), embedded wallets, social login. Multi-wallet with active wallet switching. Identity: ENS resolution on send, type a name, get the address. ENSv2 subname registration on obsideum.eth is coming soon. Visual engine: built from scratch. WebGL crystal shards with cracks that leak violet light. (Not a library). Custom canvas price chart with pinch, zoom, drag, and crosshair (also not a library.) The entire project was built from a phone. No desktop. No IDE. Pure focus. And yet the desktop experience is just as curated as the mobile. No compromises on either With that being said. This project isn't my ceiling. It's basically my floor.
