Love in the Blockchain Age—Wedding Vows as Smart Contracts

Web3 Future of Love: Blockchain Weddings Take Center Stage

By 2025, blockchain has moved beyond finance, touching even the most personal aspects of life—love, trust, and commitment. No longer just a technology for transactions, it has become a way for couples to solidify their vows with the certainty of immutable code.

A blockchain wedding means that promises are written not on paper, but into smart contracts, ensuring they remain unbreakable and free from external influence. Here, trust is automated, and witnesses are lines of code verifying an eternal bond.

What started as an experiment by tech enthusiasts has now become a symbol of a new generation’s values—sovereignty, innovation, and permanence. Across the globe, couples are leaving behind the past and embracing a future where love is decentralized and unshakable.

The First Blockchain Oath: Love, Crypto, and a 0.1 BTC Burn

In October 2014, at a Disney World conference, David Mondrus and Joуce Baio made history by recording their wedding vows on the Bitcoin blockchain. Their ceremony included a symbolic burning of 0.1 BTC through a Coin Outlet ATM, marking their love in a way that no government or religious institution could alter.

Their words—“Life is not eternal, death can separate us, blockchain is forever”—became a defining statement of the digital era. David, a tech entrepreneur and crypto advocate, wanted to show that marriage could exist independently of centralized authority. The act was both a love story and a proof-of-concept, demonstrating that the blockchain could serve as a permanent record of human relationships.

Their legacy inspired countless others. As Ethereum smart contracts emerged, blockchain weddings grew from a symbolic gesture into a global movement, redefining the very concept of commitment.

In 2021, two Coinbase employees, Rebecca Rose and Peter Kacherginsky, exchanged more than just words—they coded their vows into the Ethereum blockchain. Through the “Tabaat” smart contract, they minted NFT wedding rings, sealing their promises in just four minutes and for $587—a commitment now stored forever.

That same year in India, Shruti Nair and Anil Narasipuram took a similar approach, creating an NFT of their rings, each one engraved with their wedding vows—a fusion of romance and cryptographic permanence.

These examples prove that love, like blockchain, can be immutable, preserved for future generations in a form that time, distance, and change cannot erase.

Love in Code: How Blockchain Wedding is Reinventing Marriage

A smart contract functions as a self-executing agreement, ensuring that commitments are honored without intermediaries. In the realm of marriage, it can encode vows, promises, or even financial agreements in case of separation.

But why are couples choosing blockchain-based vows?

The first reason is durability. Traditional marriage certificates can be misplaced, ink can fade—but blockchain is unalterable. Once vows are recorded, they are permanently secured, existing beyond time and physical constraints.

Another compelling reason? Personalization. Smart contracts let couples tailor their vows, whether it’s a promise to travel together once a year or a structured financial commitment. Platforms like Smart Vows make it seamless, offering pre-designed, self-executing templates.

And then there’s independence. For those whose relationships don’t fit into traditional legal frameworks—due to distance, legal barriers, or cultural reasons—a blockchain wedding provides a valid, immutable declaration of love. In a world that is rapidly embracing digital permanence and tokenization, these unions feel less radical and more revolutionary.

Love, Tokenized: The Evolution of Commitment

The shift is undeniable. In 2022, a couple from Pune took their vows into the digital realm, using a “virtual priest” on Google Meet and sealing their commitment through NFT transfers on MetaMask. While it lacks legal recognition, the gesture speaks volumes: $35 and 15 minutes was all it took to create a permanent bond on-chain.

Other pioneers of blockchain love, like Brock Pierce and Crystal Rose, who had their blockchain wedding in 2017, have introduced annual contract renewals to their vows. Some couples are replacing gold bands with NFT rings, while others immortalize their love through virtual assets and blockchain-powered gifts.

Fast forward to 2025, and platforms like OpenSea and Rarible have simplified NFT-based wedding contracts, while developers are crafting apps for fully customizable smart contract marriages—paving the way for a digital-first approach to lifelong commitment. 

Anyone can immortalize their vows on the blockchain. Visit OpenSea, click “Create” in the upper corner, and connect your wallet—MetaMask is a popular choice. Select the single NFT creation option, then upload a file with your vows—this could be a PDF document, a heartfelt audio clip, or even a video of the ceremony.

Next, personalize your NFT with metadata: a title like “Our Vows Forever”, a description including the wedding date and couple’s names, and any additional details you wish to preserve. The “Unlockable Content” option allows you to store private messages, visible only to the NFT holder.

Thanks to lazy minting, the NFT costs nothing upfront, only being minted on the blockchain when it is sold or transferred, making digital love contracts easier than ever.

Beyond Symbolism: Smart Contracts in Action

The blockchain wedding movement is shifting from a symbolic trend to a practical solution. Couples are using smart contracts to automate shared finances, such as anniversary fund transfers or granting access to crypto assets in case of unforeseen events.

In the U.S., some legal firms are experimenting with blockchain-powered prenups, though they’re not yet legally binding. In Europe, where MiCA regulations are reshaping digital finance, stablecoins like USDC are already being used for wedding transactions. Across Asia, particularly in India, young couples are embracing blockchain weddings as a high-tech, standout experience.

The price of a Web3 wedding varies widely—from a $20 smart contract transaction to several hundred dollars for minting fully animated NFT vows. 

The blockchain wedding breathes new life into tradition—where eternity is no longer just a promise, but a line of code, secure and unbreakable. Like a ring that can never be lost or a love story that will never fade, it offers permanence in an ever-changing world. Maybe one day, etching vows onto the blockchain will be as instinctive as placing a ring on a loved one’s finger—another way to say “Forever.”
