Optimism’s airdrops attract developers by distributing OP tokens to active ecosystem contributors, incentivizing development through tangible rewards. The mechanism includes Retroactive Public Goods Funding (RetroPGF), allocating 850 million OP to fund open-source projects, as noted in X posts. Developer-specific airdrops and sequencer fee-sharing further boost participation, rewarding transaction volume on the OP Mainnet. With 550 million OP reserved for future drops, sustained engagement is encouraged. This creates a self-reinforcing cycle: contributions drive ecosystem growth, increasing blockspace demand and revenue, which funds more incentives, drawing developers to build scalable dApps.
