Liqwid V2 Source Availability (BUSL 1.1)

Summary

This is a proposal to make the Liqwid V2 smart contracts source-available under the Business Source License 1.1 (BUSL 1.1) with a fixed 4-year term.

The scope includes

  • Liqwid oracle (oracle-onchain)
  • Liqwid lending and borrowing (liqwid-onchain)
  • Liqwid governance infrastructure (agora-pro, multisig support)

Off-chain systems including UI, APIs, indexers, and related services will remain fully closed-source.


Motivation

Liqwid is at a stage where increasing transparency and composability while maintaining strategic defensibility is important for long-term ecosystem growth

Key drivers include:

  • Transparency and trust through verifiable on-chain logic
  • Security through scrutiny via external review and analysis
  • Composability enabling easier integrations and improved liquidity flow
  • Ecosystem alignment with Cardano and broader DeFi principles
  • Strong community demand for source availability
  • Improved positioning for ecosystem partnerships and funding opportunities

Why BUSL 1.1

BUSL 1.1 is chosen as a controlled source-available model that balances openness and protection

Rationale:

  • Protection against vampire attacks in a still shallow liquidity environment
  • Time for network effects to strengthen protocol position before unrestricted forking
  • Monetization control during an early growth phase
  • Transparency signaling without full loss of competitive defensibility
  • Proven design precedent with Aave using BUSL for V3 and intended continuation in V4
  • Liqwid’s eUTxO-based Aave-like lending system remains technically novel and difficult to replicate

Specification

This proposal recommends:

  • Publishing core repositories under BUSL 1.1 with a 4-year term
    • oracle-onchain
    • liqwid-onchain
    • agora-pro

Scope of release:

  • Smart contract (Plutus validator) source code
  • On-chain protocol logic and interfaces

Explicit exclusions:

  • UI, APIs, indexers, and off-chain infrastructure remain closed-source

Timeline:

  • BUSL 1.1 license term set to 4 years
  • Latest effective milestone aligned with December 2026, subject to governance approval

Expected Impact

  • Improved transparency and protocol credibility
  • Stronger integration potential across DeFi ecosystems
  • Increased composability and liquidity efficiency
  • Better alignment with ecosystem expectations around openness
  • Maintained strategic defensibility during early growth phase

Risks and Considerations

  • Forking risk due to code visibility
  • Competitive replication attempts from rival protocols
  • Security risk from protocol internals being exposed

Opening access to smart contract code introduces a perception of increased attack surface. However, relying on closed-source systems for security is not a robust strategy. Security through obscurity tends to delay, not prevent, the discovery of vulnerabilities.

By making the code source-available, Liqwid enables broader review from independent developers and security researchers, increasing the likelihood that issues are identified and resolved earlier.

To further strengthen this approach, Liqwid will launch a self-hosted responsible disclosure and bug bounty program within a maximum of 2 months following source availability, with an initial DAO treasury-seeded reward pool of 59,000 ADA. This program will incentivize external contributors to responsibly report vulnerabilities and improve overall protocol security.


Next Steps

  1. Gather community feedback and discussion
  2. Conduct a temperature check vote (off-chain)
  3. If consensus is positive, proceed to formal governance vote
  4. If approved, prepare repositories for release under defined terms

  • Yes, I support releasing Liqwid smart contracts under BUSL 1.1 with a 4-year term
  • No, I do not support this proposal

What does this mean? Will this license be available for a fee? If not, why not?

I think at this juncture, Liqwid should monetize the work completed to date for these products to drive revenue back towards Liqwid Labs to support V3.

I am worried about competitive replication, but will admit first mover advantage remains with Liqwid and V3 should be what keeps people using Liqwid.

This means Liqwid retains the commercial rights to the protocol, contracts, and application, while still enabling third parties to independently audit, inspect, and verify the business logic and security of the system. Unlike traditional open-source licenses, the rights granted under this model are more limited, particularly with respect to both commercial and non-commercial use.

Agreed - this is already reflected in the current structure through interest revenue net margins and reserve income splits that generate value for the DAO.

I think the most important objective is continuing to establish Liqwid as the premier lending protocol on Cardano. Sustaining that position comes from strengthening the protocol’s moat, expanding its influence, and continuing to deliver meaningful innovation through V3 and beyond.

Kylix, thanks for the reply. Still, can’t the protocol monetize the V2 stuff at all? I think it would be a way to bring in some revenue to the DAO. And if a competitor was able to develop a protocol to rival Liqwid, at least there was some revenue brought in before that.

I think there may be some conflation here between making the code publicly viewable and monetizing the protocol itself.

Making the V2 code available under a source-available license does not mean Liqwid gives up monetization rights or opens the door for unrestricted commercial forks. Liqwid would still retain the commercial and intellectual property rights to the protocol and application. Third parties would be able to independently audit, inspect, and verify the codebase for security and transparency purposes, but they would not have the right to commercially deploy or monetize copies of Liqwid without entering into agreements with Liqwid.

The protocol already monetizes today through protocol revenue flows (interest margins, reserve income splits, etc.) that support development. Beyond that, there are additional monetization opportunities such as licensing, white-label deployments, and enterprise/direct lending integrations - similar to approaches used elsewhere in the industry. Those opportunities are not reduced simply because the code becomes visible.

Legally, someone wanting to use Liqwid commercially would still need to work with Liqwid, much like they would if the code remained private. The difference is that making the code available improves transparency, enables independent security review, strengthens trust, and can help establish Liqwid as critical infrastructure while preserving commercial rights.

So I don’t see transparency and monetization as being at odds here. The goal is to improve auditability and trust without giving away the value the DAO has built.
