I just found out about something quite interesting happening in the institutional market. Fidelity has just announced the launch of its own stablecoin, the FIDD (Fidelity Digital Dollar), directly on Ethereum. And it's no small detail, believe me.

What draws attention here is that Fidelity chose a public blockchain instead of getting involved in those private networks that big institutions typically prefer. Just a couple of weeks ago, J.P. Morgan announced its JPM Coin on Canton, a network that focuses heavily on privacy. The DTCC was also exploring Canton to tokenize Treasuries. But Fidelity? Going straight to Ethereum.

The FIDD will be backed by cash, cash equivalents, and short-term Treasuries. It can be transferred to any address on mainnet, which means it has all the liquidity and accessibility characteristic of Ethereum. This is no coincidence.

According to experts, this marks an important turning point. Marcin Kazmierczak from RedStone summarized it well: two years ago, it would have been unthinkable for an institution the size of Fidelity to choose a public blockchain over a private one. But regulation, especially the GENIUS Act, changed the game. Now, stablecoins on public networks like Ethereum are more trustworthy because they offer greater transparency.

Neil Staunton from Superset makes an interesting point: Fidelity is not choosing Ethereum despite being a large institution, but precisely because they understand that liquidity matters. A stablecoin that cannot be moved freely doesn’t truly solve the problem. And on Ethereum, you have that interoperability with Layer 2s, access to major exchanges, and the entire open ecosystem.

Ryne Saxe from Eco sees this as a clear victory for Ethereum. And it makes sense considering that the TVL on Ethereum is around $74 billion and the stablecoin sector has already surpassed $300 billion in total market capitalization.

What’s happening here is more than a product announcement. It’s the clearest signal yet that institutional banking has already accepted public blockchains as the default infrastructure. Fidelity will launch this in the coming weeks, allowing its clients to buy or redeem tokens directly. If this becomes standard, we’re witnessing a fundamental digital shift in how institutional settlement and payments work. Definitely something to keep on the radar.
