Switching Chains for Another Shot at Success: Can It Really 'Change One's Destiny'?

Recent months have witnessed a wave of established blockchain projects migrating to new public chains, notably Base and Arbitrum, coupled with strategic pivots in their business models—essentially "re-starting" elsewhere. Examples include Sophon (moving from ZKsync to Base to cut $3M+ annual costs and focus on consumer apps), Moonbeam (shifting from Polkadot to Base to pursue decentralized AI), and Secret Network (planning a move from Cosmos to Arbitrum to explore privacy-AI integrations, though its token price plunged 30% post-announcement). A common thread is that these migrating projects are primarily layer-1 or layer-2 chains now seeking relevance in AI and real-world consumer applications. This trend highlights the relative stagnation of ecosystems like Polkadot and Cosmos, which are seeing significant outflows. However, the community remains skeptical about whether such chain-hopping truly enables a turnaround. Historical cases like y00ts NFTs (which moved from Solana to Polygon and back to Ethereum) and Synthetix (which retreated from a multi-chain strategy) show that migration often fails to deliver expected benefits and can add complexity. In today's more rational market, devoid of easy narrative or airdrop红利, simply changing chains is unlikely to be a silver bullet. For both migrating projects and destination chains, the real challenge lies not in attracting projects but in developing actual use cases that retain users.

1 Billion DOT Minted Out of Thin Air, Yet Hacker Only Made $230,000

On April 13, a security breach occurred involving the Polkadot bridge on the Ethereum network, where an attacker exploited a replay vulnerability in the MMR proof mechanism of Hyperbridge’s ISMP protocol. By reusing a historically valid proof and pairing it with a malicious request, the attacker bypassed verification and gained admin and minting rights over the wrapped DOT contract on Ethereum. They then minted 1 billion wrapped DOT tokens—2,805 times the existing supply—and attempted to liquidate them. However, due to extremely low liquidity in the wrapped DOT market, the massive sell-off crashed the token’s price by 99.98%, from $1.22 to approximately $0.000128. The attacker ultimately exchanged the tokens for only about 108.2 ETH (worth roughly $237,000), with gas costs as low as $0.74. The same exploit had been used previously in attacks on MANTA and CERE tokens, resulting in a total loss of around $242,000. Polkadot confirmed that the incident only affected DOT bridged via Hyperbridge to Ethereum and did not impact the native Polkadot network or DOT on other bridges. Exchanges including Upbit and Bithumb temporarily suspended DOT deposits and withdrawals as a precaution. The event highlights ongoing vulnerabilities in cross-chain infrastructure and the critical role of liquidity in limiting actual damages during large-scale exploits. It also reflects a broader trend of increasing DeFi security incidents in early 2026.
