Jefferies: $606M April Crypto Exploits May Force Wall Street to Rethink Blockchain

After the $293M Kelp DAO bridge hack and other April incidents, Jefferies tells clients that banks, asset managers, and payments firms may decelerate tokenization rollouts — especially bridge-dependent designs.

Investment bank Jefferies told clients on April 21 that the concentrated wave of April crypto exploits — totaling roughly $606 million, with the $293 million Kelp DAO bridge hit as centerpiece — could force banks, asset managers, and payments firms to slow their blockchain and tokenization rollouts.

What's new

Kelp DAO on April 18 was drained when attackers minted unbacked tokens and used them as cross-chain collateral, exploiting the exact bridge infrastructure that institutional tokenization depends on. The attack is linked to North Korea's Lazarus Group. Combined with Drift Protocol and other April incidents, the monthly loss total is among the highest since 2022.

Why it matters

Jefferies' read: TradFi is unlikely to abandon crypto outright, but the pace of tokenization — onchain treasuries, tokenized deposits, stablecoin rails — could decelerate as risk, compliance, and custody teams re-audit bridge-dependent designs. That matters for every bank that spent 2025 publicly committing to blockchain pilots.

The takeaway

Bridge-free tokenization designs (native-issuance on a single chain, or institutional-permissioned ledgers) may get a second look as a result. Watch BNY, JPM Onyx, and Stripe's Tempo for whether this changes 2026 Q2 rollouts.

North Korea Hackers Crossed $6B in Crypto Theft — 76% of 2026 Losses From Two Bridge Attacks: TRM

TRM Labs published its April 2026 hack accounting on April 30, and the headline number is the kind that resets industry assumptions: cumulative crypto theft attributable to North Korea-linked groups has crossed $6 billion since 2017, and Pyongyang now accounts for 76% of all 2026 hack losses through April — across just 3% of total incidents. Two April attacks did the work: a $292 million exploit of KelpDAO and a $285 million theft from Drift Protocol, totaling $577 million in a single month.
