Juicebox V3 Review 2026: Transparent Funding on Ethereum

Our verdict on Juicebox V3

7.0/10

Juicebox V3 suits builders, DAOs and communities that want to raise money on Ethereum with rules backers can verify, and supporters who are comfortable reading a project's terms. Its main strength is the mix of public rules, lockable terms and programmable payouts. The main caveat is risk: TVL is small, V3 is an older version of the protocol, and the Terms of Service put all risk on the user.

What is Juicebox V3?

Juicebox V3 is the Ethereum deployment of Juicebox, an open-source protocol for funding projects and managing the money. It is listed as a launchpad. A team, DAO or indie creator sets up a project, takes payments from anywhere and issues tokens to supporters under rules that anyone can check.

The homepage pitches it as a way to accept money transparently on your own terms. Owners can leave rules flexible, lock them over time, or launch a revnet with terms fixed from day one. The same contracts support other products, including point-of-sale payments, a social feed, collectibles and publishing tools.

The V3 listing is small, with about $134,500 in TVL on Ethereum and a 4% change over seven days. The V3 JBX token and V3.1 contracts went live in 2023, and the site now presents newer protocol versions alongside it. Treat V3 as an established but older part of a growing ecosystem.

How Juicebox V3 works

A Juicebox project is a set of smart contracts on Ethereum that hold funds and enforce rules. Anyone can pay in, and the payer receives project tokens based on the project's issuance terms. The owner can send payouts to chosen recipients and define how supporters can cash out against the remaining funds.

Rules are grouped into funding cycles. In V3, these cycles set the payout limit, token issuance and redemption terms for a period. Owners can leave terms editable or lock them. Revnets go further by fixing the financial schedule at launch.

V3 is a fork of V2 that fixes a funding cycle bug, and V3.1 contracts followed in 2023. Projects can use extras such as a buyback pool, splits for contributors, and cross-network token moves.

7 features

Key features

Transparent project funding

Projects can accept payments from anyone and set funding rules that others can inspect. Payments, payouts and rule changes appear in the public record.

Lockable rules

Owners choose which terms can change and which stay fixed. They can start flexible and lock in important parts over time.

Project tokens

Supporters receive project tokens when they pay in. The homepage also mentions a buyback pool, through which payments can buy tokens on the market.

Payouts and splits

Funds can be set aside for team members, partners and contributors, and payouts and incentives can be automated.

Revnets

Revnets are projects with a financial schedule fixed at launch. The operator keeps only a limited set of controls.

Borrowing against tokens

On some projects, holders can borrow funds against their tokens and recover them by repaying before the deadline.

Platform building blocks

The same public contracts back apps such as a point-of-sale tool, a social feed, an NFT collectibles project and a publishing tool.

Pros and cons

What we like

Open-source code that anyone can review, with two audits listed in the data
Rules and payments are on the public record
Flexible control: owners can keep terms editable, lock them or use fixed-term revnets
Supports contributor splits, buyback pools and token redemption
Reward of up to 10% for defenders who return stolen funds
Ecosystem of apps built on the same contracts, from point of sale to social tools

Watch out for

TVL is small (about $134,500 on Ethereum), so the V3 deployment has limited capital behind it
Terms of Service state that risks are borne entirely by users of the open source code
Project owners can change terms unless they lock them, so backers need to read each project's rules
The homepage now highlights newer protocol versions, so V3 is an older generation with an unclear long-term role
Fees, audit reports and team details are not laid out on the homepage; the data lists two audits but not who did them
Borrowing against tokens and cross-chain token moves are only available on some projects

Juicebox V3 fees

The homepage does not publish a fee schedule. It does show a counter for total fees paid to JBX, which indicates the protocol takes a fee on funds passing through, but the rate is not stated there.

Users also pay Ethereum network gas on every transaction. Project owners can set their own payout and redemption terms, so the cost of paying into or cashing out of a project depends on that project's rules. Check the project page before paying.

Is Juicebox V3 safe?

The protocol code is open source and the data lists two audits, though the audit firms and reports are not named on the homepage. Funds sit in smart contracts rather than with a company. That means smart-contract bugs and project-level governance are the main risks, not exchange custody.

The Terms of Service say risks are borne entirely by users of the open source code. The site offers a 10% reward for defenders who steal funds and return them, paid by all projects together. Juicebox does not publish a regulatory licence on the homepage. Backers should read each project's rules, check whether terms are locked, and only commit what they can afford to lose.

Juicebox V3 FAQs

What is Juicebox V3?

Juicebox is an open-source protocol for raising and managing money on Ethereum. A project accepts payments, issues tokens to supporters and publishes rules for how funds are paid out or redeemed. Anyone can check those rules on the public record.

How does V3 differ from earlier versions?

V3 is a fork of V2 that fixes a funding cycle bug while keeping the same project contract. The V3.1 contracts and a V3 JBX token were deployed in 2023, with a migration guide for V1 and V2 JBX holders. The Juicebox website now also presents newer protocol versions.

What is the JBX token?

JBX is the token tied to the protocol. The homepage shows a total of fees passed to JBX, so protocol fees feed back to JBX in some way. The exact fee rate is not stated on the homepage.

Is Juicebox safe?

The protocol code is open source and DefiLlama lists two audits. The Terms of Service say risks are borne entirely by users, and the project offers a 10% reward to defenders who steal funds and return them. Smart-contract risk remains, as with any DeFi protocol.

Who can use Juicebox?

Anyone who wants to accept contributions with public rules can use it. Examples on the homepage include open-source projects, campaigns, DAOs, communities and indie businesses. Supporters can pay into projects and receive tokens.

Which networks does it support?

The homepage says project tokens can be used across Ethereum, Base, Arbitrum and Optimism, with holders able to move tokens and their backing funds between supported networks. The DeFi data for this V3 listing shows Ethereum only.
