Quota

Quota is a Solana-powered usage and quota management platform for B2B/SaaS APIs. Companies deposit USDC into an on-chain Vault and allocate funds into individual Seats — each representing an API key, user, or team — with its own usage limit. Usage is enforced on-chain via Anchor smart contracts, with a Node.js backend triggering consume instructions and validating limits at both the on-chain and off-chain layer to prevent over-allocation.
