Juicebox V1 Review 2026: Programmable Fundraising on Ethereum

Juicebox V1 is the first generation of the Juicebox protocol, an open-source system on Ethereum for accepting money and managing it by public rules. It describes itself as a programmable fundraising protocol for builders and creators, light enough for a group of friends and powerful enough for a large network of anonymous contributors.

Tracking data lists the V1 contracts with about $12.5 million in value locked, the JBX token, and two audits. The live website now presents later versions of the protocol and a wider set of tools, so V1 is best read as the foundation rather than the whole product.

Projects on the site range from a project holding about $100,000 to many with only a few dollars, so activity is concentrated in a small number of projects.

A Juicebox project is a set of smart contracts that accept payments and keep track of the funds. When someone pays in, the project can issue its own token in return, at a rate the owner sets. Those tokens can represent a share of the project, and holders may be able to redeem them for part of the available funds, depending on the rules.

The owner decides how much of the money goes to payouts and splits, such as team members or partners, and how much stays available for token redemptions. Rules can start flexible and be locked later, so backers can see which terms are fixed. Every payment and rule change appears in the public record.

V1 is the original version of this design, listed on Ethereum. The current website describes newer features, such as revnets with terms fixed at launch, buyback pools, and moving tokens between networks.

The project does not publish a fee schedule for Juicebox V1. The homepage shows a running total of fees paid to JBX, so a protocol fee exists, but the rate is not stated there. Users should check the documentation and each project's page before paying in.

Beyond protocol fees, Ethereum gas costs apply to every transaction. Individual projects may also set their own payout and redemption terms, which affect what backers get back.

The protocol is open source and two audits are listed, but the homepage is explicit that users bear all risk. As with any smart-contract system, bugs, owner-set rule changes, or a badly designed project can cost backers money. The site also says defenders who steal funds and return them are encouraged to keep 10% as a reward, paid by all projects together.

The project does not name a company, licence or regulator, and the protocol is described as community-owned. Fundraising can carry legal and tax obligations that depend on where you live, so check local rules before raising or contributing funds. Only pay in what you can afford to lose.

Juicebox V1 is for crypto-native builders, DAOs, open-source teams and creators who want to take payments and issue a token with transparent rules. It also suits backers who are comfortable reading smart-contract terms and accepting that no one will cover their losses.
