Last updated 1 year ago

The Portal Network consists of swap clients and PortalOS nodes running to make the cross-chain ADMM a reality. A core enabler for multi-blockchain interoperability is exchanging assets held by mutually untrusting owners on different ledgers atomically. Since the Portal Network is non-custodial, assets are held on the native chains (like Ethereum and Bitcoin). However, the accounting occurs on a State Chain (Notary Chain), enabling highly customized AMMs on each chain.

The main components of the network are AMMs designed on each chain. Since EVM chains are Turing Complete, this involves developing smart contracts similar to Uniswap on these networks. On Bitcoin, Portal leverages a secure and highly decentralized AMM built using a multi-party HTLC. This eliminates some centralization in other protocols that manage shared key wallets. To facilitate swaps and ensure transactions are processed promptly and appropriately, a set of validators controls the transaction flow. These validators track balances across chains, process events, and execute instructions. They maintain the Notary layer, which tracks transactions and the flow of funds.
