BREAKING: SEI trades at $0.06617. Market cap sits at $469.61M. 24-hour volume drops 21.60% to $34.26M.

The token is off 0.14% on the day. It is still up 23.28% on the month.

JUST IN: Sei has joined the Mastercard Crypto Partner Program. A joint Mastercard-Sei paper is queued for release. It will outline blockchain evaluation frameworks built for financial services.

Technical picture is heavy. The 50-day SMA prints at $0.05854. The 200-day SMA prints at $0.09901. Sentiment reads Bearish. Fear and Greed Index: 34 — Fear.

Green days: 16 of 30. Volatility: 8.22%. High.

Chart watch. SEI is correcting from a monthly high near $0.08. Price is grinding toward $0.06. MACD histogram flashes fading momentum. Volume is thinning.

Bulls need $0.08 reclaim. Bears want $0.060 to crack. A break sends SEI to $0.057 support. Prior lows open up below that.

Short-term moving averages flash SELL. SMA-3, SMA-5, EMA-3, EMA-5 all red. Medium-band SMA-10 through SMA-50 print BUY. The long tail — SMA-200, EMA-200 — print SELL.

DEVELOPER WATCH: The Parallel Stack is now live on SEI V2. The open-source framework targets rollups and Layer 2 builds with parallel processing. It aims to unclog the bottlenecks dragging Ethereum-aligned L2s.

ETH-compatibility is the pitch. SEI is hunting share of Ethereum traffic. The Mastercard rail is the institutional hook.

Price targets ahead. Cryptopolitan model pegs a 2026 high near $0.14. The 2028 band: $0.35 to $0.43, average $0.36. The 2030 band: $0.78 to $0.91, average $0.81.

One-dollar print not expected until 2031. The model tags a $1.37 peak that year.

All-time high still stands. $1.14 on March 16, 2024. All-time low: $0.007989 on August 15, 2023.

Watch the $0.06 line. Watch the Mastercard paper drop. Both move the tape next.

This is a developing story.
