Streamlock is a Solana-based tokenomics platform that introduces price-gated vesting streams to align incentives between token creators and holders. Instead of allowing immediate dumping after purchase, Streamlock locks purchased tokens into customizable vesting streams that unlock based on price conditions. This mechanism discourages short-term speculation and rewards long-term conviction. The platform combines token swapping with commitment devices, creating a new primitive where buying a token is simultaneously an expression of belief in its future value. Streamlock serves both token creators seeking healthier community dynamics and traders willing to commit capital for better entry terms.
