Nula: Cardano's token streaming protocol
Five Binaries
ID: 69ef91a1985067f4ae957a56
[Cardano is missing foundational DeFi primitives](https://cardanodefi.space/) — the building blocks that make composable on-chain finance possible. Token streaming is one of the most conspicuous gaps: the rail beneath vesting, payroll, DAO grants, and structured payouts. Today these workflows happen off-chain, through centralized custodians. **Nula** fills that gap. It is an open-source, patent-free, non-extractive linear token streaming protocol on Cardano. An owner locks tokens once at a fixed accrual rate; the recipient can either withdraw what has accrued whenever they choose, or opt for automatic delivery straight to their wallet on a schedule. The protocol charges no platform fee and captures no value — every transaction pays only the standard Cardano network fee, which flows back to stake pool operators and the treasury. Nula is treasury-positive infrastructure: every stream created, every withdrawal, every delivery contributes directly to the ecosystem that funded it. Nula aligns with Cardano's vision of secure, reliable, censorship-resistant infrastructure for mission-critical applications. Recipients keep accruing tokens even if the owner disappears, the validator holds no upgrade authority over user funds, and every stream is verifiable on-chain. Both owners and recipients can be individuals or smart contracts, making Nula a composable building block for the broader Cardano DeFi ecosystem — opening the door for interoperability with DEXes, lending protocols, DAOs, and any future protocol that needs to release value over time. Token streaming is already a proven financial primitive on other chains and Cardano has no equivalent native protocol today. Supporting [market-demand data and a competitive landscape analysis](https://nula.stream/#what-does-the-competitive-market-look-like) are provided in the linked external resource, including usage metrics from Superfluid and Sablier and a comparison of Nula's design against existing streaming protocols.
Scorecard
How this score works
Each criterion is worth between 1 and 4 points. The score is the points earned out of the points on criteria that have been answered — shown as a percentage. Green is 75% or higher, Amber is 50–74%, and Red is below 50%.
Some criteria are checked automatically against the proposal data (open source, doxxed team, treasury return clauses, etc.). Others are human-judgment calls — value for money, public good, whether the deliverables are realistic. Those stay blank until a DRep ticks them.
Criteria can also be marked Not applicablewhen they don't fit the proposal — for example, "open source" doesn't apply to a DAO governance proposal with no software output. Those are excluded from the score entirely, neither helping nor hurting.
Green requires 80% coverage. If less than 80% of the applicable criteria (by points) have been answered, the verdict stays at Amber — "pending review" — even when every answered criterion passes. This proposal's coverage is currently 68% (13 of 19 applicable criteria answered). The auto-calculated band would have been Green, but coverage is below the threshold so the verdict is shown as Amber to flag that judgment criteria are still pending.

Cardano-specific demand is structural rather than expressed: no named Cardano DAOs, payroll providers, or projects committed to using Nula at launch (the proposal does not claim any). The WP3 bootstrap incentive design is itself an adoption-risk mitigation. Rated moderate because the EVM precedent is strong cross-ecosystem signal but Cardano-side named adopters are absent. Proposer's transparency about uncertainty (live FAQ, revenue calculator) is a positive signal."
