Music Rights Registry

Ledgeris was an ICO Advisor for Spxtrum Pte Ltd (formerly Spectrum 5) in preparation for their planned token sale. The SPXTROS platform was a SAAS service, which functioned as a registry for artists to permanently record music rights on the Ethereum blockchain, stipulate royalty splits and distribute license fees. Payments would be facilitated using either an ERC-20 token or a fiat-denominated coupon. Ledgeris' service included: business structure, tokenomic design, whitepaper writing, token sale planning and operations management over a 6 months engagement.

Urban Mobility Blockchain

Ledgeris provided business development, technical writing, tokenomic and operations support services to Velox. VeloxChain was an open-source blockchain protocol and marketplace for shared mobility services.

Inspired by the boom in bike sharing, the team's ambition was to democratise the sharing mobility market and accelerate the world's transition to smart cities. The initial product was a fleet of high-end bicycles that could be rented from hotels, resorts and other commercial outlets, using cryptocurrency for payment. Unfortunately, the company was not able to complete their 'smart bike' technology prototype and launch their token.

EastWind Tech

Minerals-Backed Stable Coin

Ledgeris was ICO Advisor for EastWind Tech, owned by Hastings Technology Metals, operator of rare earth mines in Australia. Inside wind turbines, computers, phones and other high-tech equipment from medical scanners to electric vehicles, are materials known as "rare earths". EastWind Tech and Hastings Technology Metals sought to provide a spot market for rare earths by launching asset tokens, specifically cryptocurrency tokens backed by rare earth metals. The project was shuttered when Hastings decided to focus solely on mining rather than secondary markets. Ledgeris' involvement included tokenomic design, whitepaper writing and related business development services.

Video Content Analysis & Search

Ledgeris provided business development, technical writing, tokenomic and operations support services to Aivon. The company developed a proprietary multidimensional index known as a ContentGraph, and then employed a mix of human experts and AI to automate indexing. The ContentGraph score was used to match advertisers, programmes and audiences to assure that appropriately classified content was delivered in a more targeted manner. The business thesis was that better metadata would lead to better monetization while solving a number of problems faced by advertisers. ContentGraph could also enable better video search. Despite attracting a number of well-known crypto investors, the project was shelved and the core technology licensed to partners.

NextID logo


Identity Management

Ledgeris developed NextID as its own in-house project. NextID was conceived as a decentralised identity management application based on the proposed W3C specification for verifiable credentials. This would enable individuals to safely store credentials and documents related to their financial, career, academic and health needs. These credential documents or certificates would be encrypted and anchored to the Ethereum public blockchain, with support for permissioned sharing and independent verification.

NextID is currently operating as an independent company, providing verifiable digital certificate issuance services for education, health and document management markets.
