S4 Airdrop Conclusion

Over 250,000 users joined S4.

S4 opened on Dec 22, 2025, the day after the S3 snapshot closed, and ran through Apr 21, 2026. Staking and governance were live throughout, with roughly $30M worth of $RIVER staked and joining governance by late March.

Strategic rounds closed in January with participation from Maelstrom, Justin Sun, and Spartan Group, alongside new partnerships on Sui and Tron, and ongoing ecosystem integration.

This article walks through what shipped, who integrated, and where the community showed up.

S4 Participation Overview

S4 drew the largest on-chain turnout in River's history.

The distribution of eligible participants shifted further toward on-chain addresses compared to S3, reflecting a more active user base.

Token and Staking Milestones

S4 was the first full season with $RIVER staking, governance voting, and Conversion 2.0 running end to end.

Three mechanism pieces shipped in the first two weeks of the season. Stake size grew steadily through March, reaching roughly $30M worth of $RIVER by Mar 23.

Staking activation

The staking mechanism went up for community review on Dec 1, then shipped one week later with Supremacy audit completed two days after launch. Voting power is tied directly to committed stake and chosen period.

Staking / Governance

Conversion 2.0

Conversion 2.0 shipped Dec 11. The integral-based distribution replaces front-loaded conversion with diminishing returns and rate recovery, keeping long-term participants in a sustainable development.

Stake growth through S4

Token moments

Two moments marked the $RIVER price action and market presence during S4: a January all-time high and the ticker acquisition on Hyperliquid in April.

Strategic Partnerships

$12M strategic rounds closed in Jan, with participation from Maelstrom, TRON DAO ( Justin Sun ), Spartan Group, and additional backers.

Community and Ecosystem Activity

14 campaigns and 8 in-person events ran through S4, spanning $10k to $50k+ reward pools across creative challenges, trading competitions, and multi-partner activations.

Community activity concentrated in APAC, LATAM, and European hubs.

Trading comps, creator challenges, and multi-partner campaigns ran back-to-back through every month of S4.

Claim Your S4 Airdrop

Season 5 begins immediately after S4 closes.

Final numbers are still being settled, and the figures below are authoritative once claim opens. River Pts remain convertible after S4 under a new conversion curve that will be published alongside the claim announcement.

Closing

Season 4 was built across many hands and many places.

River expanded to X Layer, Hyperliquid, and Base. Integrations with $U stablecoin and cbBTC support went live.

$12M strategic round closed in Jan. RIVER Stake size grew from zero to roughly $30M worth of $RIVER, with holders joining governance the moment they committed.

The community showed up in person. River Sessions landed in LATAM, Cannes Hong Kong and Paris. Connect with builders and partners in Dubai, Denver, Buenos Aires, Crecimiento, and Seoul.

Some came for S4. Others joined River in S1 and stayed through S2, S3, and S4. That continuity is what makes S5 possible.

Looking ahead, River will expand to new ecosystems and work on integrations across DEX, lending, and payments, connecting liquidity at the infrastructure level.

Thank you for being on this journey with us. S5 starts next.
