About Connext
Connext is the protocol for cross-domain intents, focused on L2-L2 communication. Connext is the most secure and decentralized protocol on the market.
Connext enables any kind of user-facing interaction between blockchains at unprecedentedly low price and latency, settling via canonical bridges for the best possible security.
To allow instant bridging, Connext is using a third-party service provider (a router) who can trustlessly complete the interaction on their behalf. Routers are rewarded with fees.
Connext has raised $22M+ in funding and has a 20-people team, and was founded by Arjun Bhuptani and Layne Haber in 2018.
About the Team
The Connext team is remote first and globally distributed, with English as primary language. We are looking for self-starters who are excited about working in a fast paced startup environment. We do not require contributors to live in specific time zones, but much of the team lives and works in the US/European timezones.
