Coinbase is taking a huge leap into the world of decentralized finance (DeFi). The largest American crypto exchange just unleashed their own decentralized exchange (DEX), throwing down the gauntlet to Aster & Hyperliquid. These two currently mega-popular Perpetual DEX platforms contributed to the resurgence of meme coins on both BNB Chain & Base Chain.
DEX functionality gives crypto traders an edge over the centralized markets, as hidden altcoin gems can be found immediately after launch. No longer needing to wait for major centralized exchanges (CEXs) to list the tokens, crypto aficionados can jump in early & not worry about dependence on a crypto brand, as all holdings are kept in a self-custodial crypto wallet.
Three Fresh Altcoins Arrive At Coinbase’s Spot
Now, Coinbase seeks to host several new altcoins on their Spot services, including Linea (LINEA), Syndicate (SYND) & Noice (NOICE). Arriving on the platform on October 9, 2025, these three alternative cryptos will be traded against the United States Dollar (USD) if the required on-demand liquidity conditions are met.
Upon the Coinbase listing news, Linea (LINEA), the largest out of the three freshly-listed crypto currencies, plunged 5%, now counting over 8% deficit in 7 days, according to CoinGecko’s price aggregator. With a global market cap of $381 million, Linea’s native coin stands outside the TOP 150 by total crypto capitalization.
The ZK-driven blockchain enjoyed an all-time high of $0.046 a month ago, and is expected to rebound with stronger liquidity, bouncing off 13% from the all-time lows of $0.021 so far. The network built by Consensys had recent talks with SWIFT for potential testing, which sparked enthusiasm among long-term holders.
While the Syndicate (SYND) token also slumped by 8.4%, the socialFi NOICE coin could be the hidden gem with 19.8% gains on Thursday, while still being at a micro-level market cap of just $25 million. Just like the rest, the altcoin can be found straight on the Coinbase app, relieving customers from entering seed phrases each time.

LINEA’s price is down 5% on Thursday afternoon; NOICE spiked 22% to ~$0.00044 (112% in 90 days)—DEX liquidity could drive bigger swings for this underdog.
NOICE turns social clout into crypto without meme fluff—its Farcaster edge and Coinbase’s US reach could easily make it a sneaky 10x play in LINEA’s shadow.
