2025 was huge for @SeiNetwork:

- ATHs in daily txs, DAU, MAU, DEX volume, and active contracts
- Now a top 10 chain across almost every metric, with the lowest tx fees in crypto
- 10s of billions in payments settled
- 100s of new apps

Here's some of what fueled this rise 🧵👇

Sei is infrastructure for modern markets. The Grid is how enterprises plug in.
