About This Grant
Apply at bosschallenge.xyz before the annual deadline (2026 cohort: applications closed Dec 31, 2025). Partner cohorts via Btrust Builders and TabConf. Not a cash grant: a free, async, mentored 1-3 month training challenge (10+ hrs/week). Included because it is the main on-ramp into funded Bitcoin OSS careers. Chaincode itself employs Core devs rather than giving open grants.
