Overview
Nula is a token streaming protocol being built on Cardano that lets one party pay another continuously over time, instead of all at once. The sender locks tokens into a smart contract (a piece of on-chain code that holds and releases funds by rule), and the recipient withdraws their accrued share whenever they want — useful for payroll, vesting, grants, and ongoing budget payouts1. The protocol charges no platform fee, so users pay only the standard Cardano network cost.
Nula is being built by Five Binaries, the engineering team behind the Blockfrost API service that thousands of Cardano apps and wallets rely on2. The protocol is designed as open-source public infrastructure: anyone can audit, fork, or build on top of it, and no single party holds upgrade keys over user funds3.
Key Features
- Pay people continuously, not in lump sums. A sender locks tokens once at a fixed accrual rate and the recipient claims their share at any moment. The same setup works for monthly salaries, multi-year vesting, or grant tranches that release over a deadline1.
- No platform fee. Users pay only the standard Cardano network transaction fee. The team takes nothing; every fee flows back to stake pool operators and the Cardano treasury1.
- Multi-asset support. Streams can be denominated in ADA or any Cardano native token, including stablecoins and project-specific tokens, so a payroll stream can pay in USD-pegged tokens while a DAO (a member-run on-chain organization) grant streams in its own governance token1.
- Smart contracts can also be senders or recipients. A DAO multisig, treasury contract, or other on-chain protocol can create or receive a stream, which lets streaming plug into the rest of Cardano's DeFi (decentralized finance — on-chain financial apps) and governance stack as a building block2.
- Optional automatic delivery. Recipients who want to be paid hands-free can opt into a scheduled delivery service, where a permissionless ticker bot sends accrued tokens straight to their wallet on a fixed cadence2.
What to Expect
The Nula site is a single-page marketing presence with sections for features, pricing, roadmap, and a long FAQ. The intended audience is end users, DAOs, and organizations that need to handle payroll, contributor vesting, grant funding, and treasury payouts on-chain — anyone moving recurring payments to a continuous, on-chain model.
The protocol is pre-mainnet; a funding proposal is in the Cardano budget process administered by Intersect2. The on-chain validator (the on-chain code that enforces stream rules) is being written in Aiken targeting Plutus V3, and the team has committed to publishing the code, tests, SDK, and reference automation under Apache 2.02.
The project is led by Five Binaries, a Cardano-native engineering shop founded in 2019. The team previously shipped Blockfrost, a Cardano API service used by thousands of apps and wallets, and has delivered prior Project Catalyst proposals4. Visitors should expect a roadmap-stage entry rather than a working product, with the project's stage tag carrying that signal across the directory.
