We are thrilled to introduce the implementation of loan smart contracts, that allow lending and borrowing directly on chain. Loan contracts are essential financial tools that allow individuals or entities to borrow money with agreed-upon terms and conditions. Leveraging the strengths of smart contract technology has the potential to revolutionize…

We are excited to announce the implementation of option contracts on chain, utilizing the power of Bitcoin covenants. This allows the execution of sophisticated financial contracts such as call and put options directly on a blockchain, as long as the chain supports Bitcoin-style covenants such as on Bitcoin SV and…

We have developed limit orders on chain. It is based on a type of smart contract called covenants, where an output can be spent only if the transaction that spends it meets specific criteria. To demonstrate how it works, we have implemented Ordinals tokens sell and buy limit orders paid…

On-chain Private Computing — Everything on a blockchain is publicly accessible. This gives rise to privacy concerns, when working with sensitive data. To ensure data on chain remains confidential and secure, we employ a technique called homomorphic encryption (HE). It allows computations to be performed on encrypted data without decrypting it, opening up new…

The embracing of 1Sat Ordinals by the Bitcoin community is rapidly increasing with over 48 million inscriptions, and there is a ton of excitement around this new innovation. Despite the excitement, the tooling for ordinal inscriptions remains underdeveloped, making it challenging to build with Ordinals. …

Sealed auctions are a well-established method for trading and selling goods and services. With the advent of blockchain technology, sealed auctions can now be implemented on-chain, offering a number of advantages over traditional auctions. In this article, we will implement of a collateralized sealed auction on UTXO-based smart contract blockchains…

Catastrophe bonds are a type of financial instrument that allows investors to hedge against the risk of natural disasters. They work by issuing bonds that pay out to…

Control Distribution of BSV-20 Tokens — In our last article, we have shown smart contracts can control transfers of BSV-20 tokens after minting. Today, we demonstrate how to control distribution/issuance of such tokens. Tickerless mode BSV-20 introduces a tickerless mode in V2 and takes a different approach from V1. Deploy To deploy and mint a token with a supply…

Fungible BSV-20 Tokens based on Ordinals — Previously, we have shown how to integrate Bitcoin smart contracts with Ordinals, which can be regarded as NFTs on chain. In this article, we show how to integrate them with the fungible version, i.e., BSV-20 tokens. …
