Community developer isleepcode released two new tools for Neo N3 within four days in May: Gasetta and neovest. Both are open-source projects built for the Neo ecosystem, and they represent grassroots contributions from an active builder in the space.
isleepcode operates under the smartargs organization on GitHub. He was previously featured by NNT for the neocity blockchain visualization project back in March. The two new tools add more functionality for developers and users on Neo N3.
Gasetta: tracking Neo core development
Gasetta was released on May 16. It provides AI-generated summaries of activity across Neo’s GitHub repositories. The tool tracks what the core team is shipping and monitors comments from Neo co-founders Da Hongfei and Erik Zhang. This offers users a window into the development progress of Neo N4.
According to isleepcode, Gasetta helps people “stay up to date on what the core team is shipping, what @dahongfei and @erikzhang are commenting on, and where N4 actually stands.” The tool focuses on the neo-project GitHub organization, which hosts more than 25 repositories, including the core Neo implementation, Neo VM, and developer tooling.
neovest: trustless token vesting
neovest was released on May 12. It is a trustless token vesting smart contract for Neo N3. The contract locks tokens to a predefined schedule and is immutable once deployed. The owner cannot withdraw early, change unlock dates, redirect beneficiaries, or upgrade the contract. The only exception is a revoke function that works only on locks explicitly marked as revocable at creation. Beneficiaries claim vested tokens directly from the vault without needing a custodian or operator.
The contract supports three schedule types: cliff (single-date unlock), linear (continuous vesting between two dates with an optional cliff), and stepped (equal tranches at evenly spaced timestamps, supporting one to 64 tranches). All locks, schedules, beneficiaries, and claims are publicly readable via RPC.
Deployment is handled through a browser-based interface. Users connect a wallet, review a deterministic contract hash, and sign a single transaction. A static dashboard runs against any deployment without requiring a backend, allowing anyone to audit vesting schedules. CLI deployment is also available for scripted workflows.
neovest is built with the neow3j Java smart contract framework and a Vite, React, and TypeScript dashboard. It is open-source under an MIT license. The repository includes a demo vault featuring a fictional Hyperion token with 26 locks across six categories.
At present, neovest is in alpha. The contract has internal tests but has not been externally audited. The developer’s security documentation advises against depositing production funds without reviewing the known limitations outlined in the repository.
Both tools sit alongside isleepcode’s broader body of work in the smartargs organization. That includes a Neo N3 type generator, an AI-powered blockchain assistant, and a Sign-In With Neo starter kit. Gasetta can be accessed at gasetta.com, and the neovest repository is available on GitHub.
