Core Learning Concepts
  • Lock-and-Mint bridge mechanics vs Burn-and-Mint
  • Wrapped tokens (e.g. wBTC, wETH) as synthetic liabilities
  • Historical bridge hacks (Ronin $625M, Wormhole $320M, Nomad $190M)

Blockchains are isolated state networks; Ethereum cannot read Solana's memory natively. To transfer assets between chains, users rely on Cross-Chain Bridges.

Most bridges utilize 'Lock-and-Mint': you lock 1.0 native BTC on Bitcoin with a custodian or bridge multisig, and the bridge mints 1.0 wrapped BTC (wBTC) on Ethereum. You do not hold real Bitcoin on Ethereum; you hold an IOU redeemable for the locked Bitcoin.

Bridges represent the single most attacked attack vector in crypto history because they centralize hundreds of millions of dollars in locked contract honeypots. If the bridge keys are compromised, the wrapped token becomes worthless overnight.

Institutional Execution Insight

Do not hold wrapped assets across multi-year bear markets. Un-bridge your assets back to their native Layer-1 blockchains (native BTC, native ETH) for cold custody.
