Barter(X: BarterDeFi) is the leading solver‑based execution layer operating across every major EVM chain. Since launching in 2023, the protocol has routed more than $11.5 billion in swap volume over 65k+ users. By interpreting every transaction as an intent, Barter’s network of highly‑specialized solvers assembles and atomically executes the optimal path for each trade, delivering best‑in‑class prices.Barter is developing DeFi primitive that turns any wallet into AMM or a Liquidity Source. Instead of locking tokens in a pool, liquidity providers keep full custody of their assets in their own wallets while earning fees without relinquishing control or paying gas.What you’ll be doing Develop and maintain highly interactive, responsive, and user-friendly frontend applications for onchain products.
