This week @PortaltoBitcoin went live on mainnet. It’s easy to miss how big this is. Portal built BTCFi around atomic swaps and multi-chain liquidity coordination instead of wrapped tokens or bridge custody. The MC-LAMM model links Bitcoin and EVM chains directly through hash time-locked contracts verified by onchain validators and peers on the Portal OS. PTB is what happens when someone actually engineers interoperability instead of simulating it. Real BTC, real swaps, no synthetic layers pretending to be decentralized.(NekoZ)
