Background
Before delving into the specifics of Bitcoin’s adoption, it’s crucial to understand the economic landscape of El Salvador. Historically, the country has faced significant economic challenges, including high poverty rates, limited access to financial services, and a heavy reliance on remittances, which account for about 20% of its GDP. Since 2001, El Salvador has used the US dollar as its official currency, which has provided stability but also limited monetary policy options for the government.
Bitcoin Law
On June 9, 2021, El Salvador made headlines worldwide by becoming the first country to adopt Bitcoin as legal tender. The Bitcoin Law, proposed by President Nayib Bukele and swiftly passed by the Legislative Assembly, mandates that Bitcoin must be accepted as a form of payment by all businesses and allows it to be used for all debts, public or private. The law’s key provisions include:
- Mandatory Acceptance: All economic agents must accept Bitcoin as payment when offered by the buyer.
- Tax Contributions: Tax contributions can be paid in Bitcoin.
- Pricing: Prices can be expressed in Bitcoin.
- Exchanges: Exchanges between Bitcoin and the US dollar will be exempt from capital gains tax.
- Government Support: The government will promote the necessary training and mechanisms so that the population can access Bitcoin transactions.
The initial public response was mixed. While some saw it as a groundbreaking move to modernize the economy, others were skeptical about the volatility of Bitcoin and its potential impacts on everyday transactions.
Implementation
The implementation of Bitcoin involved several key steps:
- Chivo Wallet: The government developed the Chivo Wallet, a digital wallet that allows users to store and transact in Bitcoin and US dollars. To incentivize adoption, each user who signed up received $30 worth of Bitcoin.
- Bitcoin ATMs: A network of Bitcoin ATMs was established across the country to facilitate the exchange between Bitcoin and US dollars.
- Government Investments: The Salvadoran government made several Bitcoin purchases, intending to stabilize the market and show confidence in the new system.
Despite initial technical glitches and skepticism, the government continued to promote Bitcoin adoption through educational campaigns and infrastructure development.

Understanding Non-Fungible Tokens (NFTs)
What are NFTs?
Non-Fungible Tokens (NFTs) are a unique type of digital asset. Each NFT is distinct and cannot be replicated, which differentiates them from cryptocurrencies like Bitcoin or Ethereum, where each unit is identical.
What Can NFTs Represent?
NFTs can represent a wide array of digital and real-world items, including digital artwork, music, in-game items, videos, and even real-world assets like property rights.
Smart Contracts and Minting NFTs
The creation of NFTs involves the use of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. These smart contracts are used during the minting process, which is the term used for creating an NFT.
OpenZeppelin Contracts
OpenZeppelin provides a library of open-source smart contracts that are secure and have been thoroughly tested. These contracts are often used for creating NFTs and include implementations of standards like ERC-721 and ERC-1155. OpenZeppelin contracts are considered the gold standard for smart contract development and are used by many in the industry.
Fungible vs Non-Fungible Tokens
Fungible tokens are interchangeable and identical to each other. For instance, cryptocurrencies like Bitcoin or Ethereum are fungible tokens. If you have 1 Bitcoin, it’s the same as any other 1 Bitcoin.
On the other hand, non-fungible tokens (NFTs) are unique and cannot be interchanged with any other token. Each NFT has a distinct value based on its attributes. For example, consider a ticket to a concert. Each ticket (an NFT in this case) is unique based on its specific information such as the seat number, section, and row.
Minting an NFT
Minting an NFT is the process of creating a unique digital asset on a blockchain. This process involves transforming digital data into a unique digital asset, or NFT, that is recorded on the blockchain.
In conclusion, NFTs represent a new frontier in the digital world, offering a unique way to own and trade digital and real-world assets. Through the use of blockchain technology, smart contracts, and standards provided by libraries like OpenZeppelin, NFTs are changing the way we think about ownership and trade in the digital age.
