Optimism’s airdrops attract developers by distributing OP tokens (19% of initial supply) to reward ecosystem contributions, like building dApps or governance participation. Incentives include the Ecosystem Fund, funding projects directly, and Retroactive Public Goods Funding (RetroPGF), rewarding impactful past work with 20% of supply. Developer airdrops and sequencer fee sharing (e.g., via Mode) provide ongoing revenue, while governance voting with OP tokens empowers developers to shape the ecosystem. This mix of financial rewards, sustainable funding, and influence drives developer engagement in Optimism’s scalable Layer 2 environment.
