The Sui Foundation just gave Bitcoin a serious wake-up call. In a May 1 blog post, Sui announced it's integrating sBTC (Stacks’ Bitcoin-backed token) and supporting the Stacks network, bringing Bitcoin DeFi or BTCfi to the next level. In short, no more watching BTC sit around like it’s retired.

No More Centralized Babysitters

sBTC, developed by Bitcoin layer-2 Stacks, lets users flex their BTC in DeFi without trusting some centralized custodian not to vanish overnight. Sui, in its new Bitcoin glow-up, is even jumping in as a Stacks validator. Yes, validator. They're not just talking the talk, they're validating it too.

Big Talk from Mysten Labs

“For too long, BTC has been treated as a passive asset,” said Mysten Labs co-founder Adeniyi Abiodun. “sBTC on Sui means holders can earn yield, participate in DeFi, and stay true to Bitcoin’s trustless ethos—all on Sui, a blockchain built for performance and scale.”

Translation: no more hoarding and hoping. BTC holders can now lend, borrow, trade, and possibly sleep better at night.

BTCfi Boom Is Real

With $6.5 billion already locked in Bitcoin DeFi, it's safe to say the BTCfi party is heating up. Sui is showing up in style with an object-based architecture and parallel processing that screams, “I’m built for scale.”

Oh, and Sui’s TVL (Total Value Locked)? It just jumped 50% in the past month, reaching $1.8 billion. More than 10% of that now comes from Bitcoin-related assets. BTC is finally leaving the couch.

Stablecoins and Bridges and Mastercard, Oh My!

Sui isn’t just throwing Bitcoin into the DeFi blender. Stablecoin inflows on the chain hit a record-breaking $888 million on May 1, says DeFiLlama. And according to on-chain sleuth Torero Romero, about 29% of Ethereum outflows through Wormhole have landed on Sui over the past year. Apparently, everyone’s moving in.

Also, Sui just got itself a Mastercard Flex. Thanks to a partnership with xPortal and xMoney, you can now use SUI all across Europe with a virtual card. Tap, pay, and DeFi your day.

Big money’s catching on, too. Grayscale launched the SUI Trust, letting accredited investors get in on the action safely wrapped in Wall Street-approved paperwork.

With $1.6 trillion in sleepy Bitcoin capital just waiting to be put to work, sBTC on Sui could be the caffeine jolt the crypto OG finally needed.
