An embedded domain-specific language based on TypeScript that compiles to Bitcoin Script. Tooling includes a VS Code extension, browser playground, debugger and testing framework; the company has since extended its work toward BTC, Runes and zero-knowledge proofs.
Smart Contracts & Tokenisation
Yenpoint
Founded in Sendai in August 2020 and headed by representative director Ken Sato, this Japanese firm builds UTXO-based blockchain products: a wallet that hides the crypto layer from end users, a digital marketplace, a trading-card game and an NFT API for developers.
Vaionex Corporation
Delaware-registered developer that maintains the STAS token SDK and has since broadened into a portfolio of applied AI tools, among them ChainFacts for blockchain intelligence, TimeSeal for data integrity and products aimed at legal, education and finance workflows.
STAS
A token protocol whose name stands for Substantiated Tokens from Actualized Satoshis. Tokens are represented directly by satoshis carrying a locking script, and an open-source JavaScript SDK handles issuance, transfer, splitting, merging, redemption and atomic swaps.
Runar
Compiles contracts written in TypeScript, Go, Rust, Python and several other languages down to Bitcoin Script. Adds UTXO-based state machines, a token standard and deterministic builds, with a browser playground and debugger hosted separately at runar.run.
MintFlow
Alpha-stage tool for issuing tradeable access passes on Bitcoin. Subscriptions, memberships, loyalty schemes and event tickets are minted as NFTs, payouts settle in MNEE stablecoin, and partners can drop users straight into a pre-filled mint wizard from their own site.
Elas
Australian engineering firm working on ledger and tokenisation frameworks built on the UTXO model. Its catalogue spans a multi-signature business wallet, supply-chain provenance for luxury goods, a blockchain data API and an encrypted paid-email product.
Bitcoin Mint
A desktop and progressive web application aimed at people designing their own currency notes, combining layered artwork tools with BSV-20 token issuance, document co-signing and an encrypted identity vault. Released by The Bitcoin Corporation with source published on GitHub.
