- Cardano developer Sebastien Guillemot reveals a $460,000 donation to the Cardano treasury by his team at dcSpark.
- The contribution includes a $400,000 loan and $60,000 in interest, calculated at 6% APR.
- The donation was enabled by a newly added on-chain treasury donation feature, supported in an updated Cardano Rust SDK.
Cardano just got a serious vote of confidence from within its own ranks. Sebastien Guillemot — a widely respected voice in the Cardano community — recently disclosed that his company dcSpark has officially donated 686,567 ADA to the Cardano Treasury, worth approximately $460,000 at the time of contribution.
This wasn’t just a symbolic gesture. The amount includes a $400,000 loan alongside $60,000 in interest, with the entire transaction made possible by a newly released treasury donation mechanism that dcSpark itself helped bring to life.
Interest-Powered Cardano Contribution
Guillemot explained that the donation had been planned for some time but was delayed as the team waited for the treasury donation feature to go live on-chain. To ensure fairness, they tracked interest month-by-month using a 6% annual percentage rate (APR)—calculating the full $60,000 over the loan’s holding period.
This wasn’t a case of theory meeting practice—it was a builder donating using the very tools they built. Guillemot and dcSpark also released an upgraded Cardano Rust SDK, specifically tailored to support the new donation feature, making it easier for other developers to follow suit and contribute directly to the protocol’s future.
Perhaps the most intriguing detail? The ADA used for the donation was only purchased days ago, at an average price of $0.67 per token. Simple math puts the contribution at just under 686,567 ADA—a massive gift to the network’s war chest.
However, since the purchase, ADA’s price hasn’t held steady. Like much of the crypto market, Cardano has seen a sharp sell-off, dropping to around $0.5231 at the time of writing.
Guillemot isn’t bothered by the price dip. Instead, he emphasized the long-term impact of increasing the Cardano treasury’s reserve. With more funds available for grants, development, and future initiatives, this donation could set a powerful precedent for ecosystem self-sustainability.
In his view, real builders don’t wait for perfect conditions—they create them. And by contributing both code and capital, dcSpark is doubling down on Cardano’s future.
