An On-Chain Love Letter
Lin Wan first met Chen Yu at an online meeting in the Ethereum developer community.
It was the winter of 2024. ETH was hovering around $2,000, and the whole market was quiet and cold—much like her mood at the time. She had just ended a three-year relationship. Her ex had told her she was unrealistic, always obsessing over blockchain, and that one day she’d end up starving. Lin Wan didn’t argue. She simply converted half of her breakup settlement into ETH and stored it in her hardware wallet.
Chen Yu was the keynote speaker at the event. His topic was emotional applications for smart contracts. He said the most romantic thing about blockchain was its immutability: once something was written to it, no one could erase it. Lin Wan thought he was a bit of an idealist, but there was a sincerity in his eyes that put her at ease.
After the meeting, they started chatting on Discord. They talked about everything from Solidity syntax to Vitalik’s design philosophy, from DeFi liquidity pools to their favorite tokens. Chen Yu said the first altcoin he ever bought was GLMR. It had cost just a few cents back then, and he’d used it in an experiment: writing a message into a contract’s storage on the Moonbeam chain.
“What did it say?” Lin Wan asked.
“You’ll find out when the time is right,” Chen Yu said.
And so they began a long-distance relationship. Lin Wan was in Shanghai, Chen Yu in Singapore, with the whole South China Sea between them. Their dates were unusual. Sometimes they’d deploy a small contract on-chain together; sometimes they’d add liquidity to the same pool. Chen Yu called it “sharing risk exposure.” Lin Wan would laugh until she doubled over and say, “Can you ever just tell me you love me like a normal person?”
Chen Yu would answer seriously, “Saying ‘I love you’ on the blockchain is more meaningful than saying it anywhere else. The record stays there forever. It won’t disappear just because we argue, and it can’t be deleted if we break up.”
In the spring of 2025, the market began to recover. BTC climbed from $60,000 to over $80,000, and ETH followed, rising back above $2,500. Lin Wan’s holdings doubled, but what mattered most to her wasn’t the number in her account. It was the on-chain love letter Chen Yu wrote to her every week.
Each letter was a transaction, with its message tucked into the memo field. Sometimes it was a line of poetry; sometimes it was an inside joke only the two of them understood. Lin Wan collected them one by one, like gathering stars.
That summer, MET suddenly surged by 26 percent. Chen Yu messaged Lin Wan right away: “Remember that GLMR I bought first? It’s gone from a few cents to a whole cent now. It’s not much, but more people can finally see what I wrote back then.”
Curious, Lin Wan looked up the transaction. In the Moonbeam chain’s old contract storage, a line of text lay quietly waiting.
“Lin Wan, you’re the best code I’ve ever written on this chain.”
Her eyes instantly filled with tears.
By autumn, BTC had broken through $83,000. Chen Yu suddenly told her he was going to do something big. He spent two full weeks writing a special smart contract. Every time a block was confirmed, it would automatically send a small amount of ETH from his wallet to Lin Wan’s address, with the same message forever written in the memo field.
“What is this?” Lin Wan asked.
“This is my heartbeat,” Chen Yu said. “As long as the contract is running and the chain keeps producing blocks, you’ll always receive my messages. Even if one day we’re no longer together, these transaction records won’t disappear. They’ll stay on-chain forever, like a love letter that can never finish being delivered.”
Lin Wan watched the transaction get confirmed. In the memo field, it read: “Wanwan, this is the 120th love letter I’ve written to you.”
Suddenly, she understood. Some people don’t tell you they love you with words or send you flowers. They show it in the way they know best, writing it onto the blockchain one transaction at a time, for the whole world to witness, in a way even time can’t alter.
Outside the window, dusk settled over Shanghai. On the screen, candlestick charts kept flickering. Lin Wan leaned back in her chair and looked at the 120 small transfers in her wallet. Each one was Chen Yu’s heartbeat; each one was tenderness that could never be altered.
She thought, this must be the best kind of love in crypto. Not a get-rich-quick legend, not the thrill of watching your money double, but having someone willing to write what matters most to him onto a chain that runs forever, just to tell you:
I’m here. I’ll always be here.
