Company profile
researched Aug 2026Mintbase builds tooling for creating and operating non-fungible token (NFT) applications. Its public repositories include MintbaseJS, a TypeScript library used for transactions on mintbase.io; Rust smart contracts covering a market, a NEP-171 NFT store and a store factory; dapp templates for launching a minter, market or gallery; a UI component library; indexer-backed developer documentation; and Minsta, a meta-transaction selfie-minting engine. Additional repositories include an embeddable NFT market bridge and Arak, a general-purpose Ethereum event indexer. The organization README is titled "Bitte Protocol + Mintbase" and states the tooling is on the NEAR blockchain, and it links to contract audits, a grants program and a services status page [0].
An earlier npm-distributed "mintbase" package provided a general-purpose API for interacting with NEAR, Arweave and other supported blockchains and decentralized file storage systems, covering wallet initialization, connection and account-detail retrieval on NEAR mainnet and testnet using a developer API key obtained from the Developer tab on Mintbase. That version was marked for deprecation during 2023, with migration paths promised and support offered through GitHub issues and a developer Telegram channel; it is MIT licensed [1].
Press coverage describes the company as a Lisbon, Portugal-based software startup developing a tool used to create NFT stores, framed as a platform allowing artists to sell digital art, musicians to release music and event organizers to sell tickets as NFTs [2].
Founding story
According to press coverage of its Series A, Mintbase was founded in 2019 by Carolin Wend and Nate Geier, with the aim of letting anyone create NFTs without dealing with the underlying technical complexity [2].
Business model
Mintbase distributes open-source developer libraries, smart contracts and templates under permissive licences (MIT for MintbaseJS and the templates) and operates a hosted product at mintbase.io that issues developer API keys; it also runs a grants program for builders. The sources do not describe pricing or how revenue is generated [0][1].
Traction
Public signals are limited to repository activity: 67 repositories in the GitHub organization, with 62 stars on the archived mintbase-js library, 45 on the templates repository, and continued commits to the mintbase-bridge and Arak repositories into 2025-2026 [0].
Latest developments
The GitHub organization README frames the tooling as "Bitte Protocol + Mintbase." Several flagship repositories (mintbase-js, mintbase-core, minsta) are archived, with mintbase-js last updated in March 2025, while mintbase-bridge shows activity into February 2026 and the Arak Ethereum indexer into November 2025 [0].
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Sources characterise Mintbase as a Lisbon-based startup in the blockchain, e-commerce and software-services categories providing tooling to create NFT stores; its Series A investor set consists largely of crypto-focused funds [2].
Technology
The stack combines Rust smart contracts on NEAR (NEP-171 NFT store, market and factory contracts, with audits published), TypeScript client libraries (MintbaseJS, a wallet-selector fork, a UI component library) and indexers for querying on-chain data, plus Arak, a general-purpose Ethereum event indexer. The legacy JavaScript API supported NEAR, Arweave and other blockchains and decentralized file storage systems, exposing wallet connection, account details and data-retrieval modules [0][1].
Go-to-market
Distribution is developer-led: public GitHub repositories, npm packages, templates for spinning up minters, markets and galleries, published developer documentation, a grants program, and community support through GitHub issues and a developer Telegram channel. Access to the hosted API requires a key obtained from the Developer tab on mintbase.io [0][1].
Developers building NFT applications on NEAR, and end users creating NFTs without technical expertise β cited examples include artists selling digital art, musicians distributing music, and event organizers selling tickets [1][2].
Geography
Reported as based in Lisbon, Portugal [2].
History
The company was founded in 2019 and was initially seeded with $1 million in 2020, followed by a $7.5 million Series A reported in April 2022 [2]. Its JavaScript API package for NEAR and Arweave was slated for deprecation during 2023 in favour of a newer documentation set and library [1]. The GitHub organization README now presents the tooling under a combined "Bitte Protocol + Mintbase" heading, and several core repositories β mintbase-js, mintbase-core and minsta β are archived, while others such as mintbase-bridge and the Arak Ethereum event indexer continued to receive commits into 2025 and 2026 [0].
Risks & controversies
The sources note deprecation of the original mintbase JavaScript API during 2023 and the archiving of several core repositories, which implies migration burden for dependent developers; no controversies are reported in the material [0][1].
