If you’re looking at which altcoins could deliver the biggest gains in 2025, two names keep popping up: Ondo Finance and Sei Network.
They’re both growing fast, but in different directions. One’s building the future of tokenized real-world assets. The other is focused on high-speed DeFi with a powerful tech upgrade on the way.
In a new video from Altcoin Buzz with 464K subscribers, these two were compared side-by-side in what they called a “Battle of the Big Caps.” The breakdown covers everything from investor interest to market structure and plans.
Let’s get into it.

What you'll learn 👉
SEI Targets High-Speed DeFi and EVM Expansion
Sei Network is making a name for itself in the DeFi space thanks to its blazing fast blockchain. Unlike traditional chains that process transactions one-by-one, SEI handles them in parallel, meaning it can do more, faster.
Right now, Sei is preparing to switch from Cosmos to an EVM-based chain through an upgrade called Giga. That’s expected to scale the network to 250,000 transactions per second.
The goal? Compete with web2 giants like Google in terms of speed and scalability. It’s not just theory either, Giga changes the way storage and consensus work at the base level.
Big names are taking notice. In April, World Liberty Financial bought over $770K worth of SEI. Even Circle, the company behind USDC, holds some SEI.
And yes, native USDC is coming to Sei, bringing more than $60 billion in stablecoin liquidity along with it. Chainlink’s CCIP is also now integrated, letting Sei connect to over 60 blockchains.
SEI price is around $0.36, with a $2 billion market cap, and it’s up 65% over the past month. It’s also dipping its toes into the RWA sector, with Ando’s USDY stablecoin launching on its network. All signs point to Sei lining itself up to bridge DeFi and real-world assets.
ONDO Expands Tokenized Securities and RWA Alliances
Now let’s talk about Ondo Finance, the current leader in the RWA space. If tokenizing real-world assets is the next big thing in crypto, ONDO is already deep into it.
Their Global Markets feature is designed to bring public securities like stocks and ETFs on-chain, allowing 24/7 access and fee-free transfers, without middlemen.
The numbers backing this up are massive. U.S. treasuries and stocks account for around $90 trillion, and only a small slice of that is on-chain right now. ONDO wants to change that, and they’re making moves to do it.
They’ve built a growing Global Market Alliance with platforms like BNB Chain and Bitget, and acquired firms like Strangelove and Oasis Pro (a registered SEC broker-dealer). These steps help Ondo offer a fully compliant setup for tokenized securities, especially for U.S.-based investors.
ONDO price is trading at about $1.11 with a $3.2 billion market cap, and is up 62% in the past 30 days. There’s also talk of a potential ETF filing from 21Shares tied to ONDO, which could bring even more eyes to the project.
So, Which One Has the Edge?
SEI and ONDO have strong cases going into 2025. SEI is faster, more scalable, and branching into RWAs while staying rooted in DeFi.
ONDO, on the other hand, is already leading in the RWA sector and locking in partnerships that give it a first-mover advantage.
Altcoin Buzz wraps it up by leaning slightly toward ONDO, mostly because of its traction with institutions and real-world use cases. That said, SEI’s lower market cap and upcoming upgrades leave plenty of room for growth.
No matter which one comes out on top, both are shaping up to be strong contenders in the next bull market.
