Solana Weekly Recap (August 30, 2026): The Disinflation Mandate, a Card Exploit, the Six-Week Schedule
The Solana weekly recap: the first binding on-chain vote doubles disinflation — by a hair and not yet active. A card contract exploit shows the boundary of self-custody, and the Foundation lays out the infra calendar through October.
The week belonged to governance: the first binding on-chain vote in Solana’s history decided — two yes, one no, and the most important result by a third of a percentage point. Alongside it, a security lesson about card balances and a concrete infra schedule through October. We summarize and link our full coverage for each.
Governance: The First Binding Vote
- SGP-0002 passed — by a hair: The disinflation doubling (15 to 30 percent per year) reached 67.00 percent approval against a 66.67 threshold — at 60.7 percent stake participation, with late swings by large validators. The decisive framing: the mandate is issued, the emission curve only changes with the implementation and activation of SIMD-0550. → Tokenomics thread
- SGP-0001 (constitution) passed, SGP-0003 (fee reform) failed: The constitution passed with roughly 86 percent; the resource-based fee reform missed the two-thirds threshold at 53.9 percent — with the majority of non-approving stake abstaining rather than rejecting. → All results · Fee article with update
Security
- The card lesson: An exploit in an outdated version of a Rain card contract drained card balances of 1,685 Avici users (roughly $500,000) — self-custody wallets stayed untouched, and refunds plus 10 percent cashback were complete within a day. The boundary of self-custody sits where the balance lives after the top-up. → Full story
Infrastructure
- The six-week schedule: The Foundation firms up the calendar — rent opener next week (stage 1 runs on testnet), transaction format v1 on September 9, next slot time stage, Alpenglow targeting October. → Agave article with update
- Streaming before execution: Helius brought preprocessedSubscribe into public beta — decoded transactions from shreds before they are “processed”; an early signal, not a result. → Full story
Wallets
- Phantom ends Sui: Cutoff September 24 — fee-waived swap path or export to a Sui-native wallet; funds stay safe on-chain. → Full story
- Solflare brings perps into the wallet: Over 65 markets, settled via Phoenix’s on-chain orderbook — leveraged products with the risk to match. → Full story
Ecosystem
- Short notes: Bitwise reported one billion US dollars in assets under management for its staking ETF BSOL, ten months after launch (own figure); Solana School’s fall class starts August 31.
