Web3 Senior Backend Engineer (GoLang/DevOps)

About Aarc

Aarc is a modular protocol for building chain abstracted decentralized applications (dApps). Aarc developers can seamlessly unify users' accounts and liquidity from any blockchain without the complexities of multi-chain deployment, dApp migration, or contract modifications. Using our intuitive and use-case-specific SDKs, developers can create chain-agnostic dApps in just a few days. In today's multi-chain environment, Aarc aims to create a future where dApps can function without the burden of chain-specific considerations and quickly access a multi-chain user base.
