Liquidity Concerns Mount as Coinbase Struggles with Solana Transactions

Coinbase, the largest cryptocurrency exchange in the U.S., is under fire as users report lengthy delays - some lasting over 14 hours - for processing Solana (SOL) transactions.

These disruptions have led to speculation about liquidity issues and questions regarding the exchange’s operational integrity.

Amid user complaints, rumors suggest Coinbase may be staking customers’ SOL without explicit consent to earn yield. Critics argue that delays might stem from the time required to unstake SOL to fulfill withdrawals. Some users have highlighted large SOL transactions to Coinbase, flagged by blockchain trackers, as potential evidence of liquidity management challenges.

Concerns about Coinbase’s solvency have reignited demands for Proof of Reserve (PoR) audits, a measure widely discussed after the collapse of FTX. Crypto analysts have raised questions about whether Coinbase is struggling to maintain liquid reserves, especially as its largest Solana validator is reportedly unstaking significant amounts of SOL.

The exchange attributed the delays to technical and blockchain-related challenges, but developers familiar with Solana have pointed to Coinbase’s infrastructure as the issue. They argue the platform may not be optimized for Solana’s rapid transaction speeds, causing processing bottlenecks.

This incident adds to ongoing scrutiny of Coinbase’s custody practices. Recent concerns were also raised in relation to BlackRock’s Bitcoin ETF filings, where investors pushed for greater transparency in Coinbase’s custodial operations. The exchange’s new Bitcoin-backed USDC loans have further fueled debates about its operational priorities.

With mounting criticism, Coinbase faces increasing pressure to address user concerns and prove its commitment to transparency and reliability.
