- Automated asset management through customizable rules.
- Seamless peer-to-peer and AMM-based swaps.
- AI-driven monitoring of asset performance and trading trends.
- Liquidity provisioning to a multi-chain dynamic market maker.
These products aim to redefine Bitcoin’s utility, bringing it closer to mainstream adoption and broadening its applications within the decentralized economy.
Liquidity Management Process
- Adding Liquidity: Liquidity providers deposit assets by creating an account on the Portal Notary Chain and requesting a Deposit Address for their funds.
- Managing Liquidity: Providers manage their balances to facilitate Range and Limit Orders, ensuring efficient and seamless trading operations.
- Withdrawing Liquidity: Providers specify a destination address for withdrawals, with validators overseeing the process to ensure smooth and secure transactions.
In addition, the Portal Wallet integrates support for Lightning Network transactions, allowing users to make fast and secure payments without operating their Lightning node.
PortalOS
The Portal network is powered by PortalOS, a sophisticated framework of distributed nodes that execute network-level protocols and ensure consensus on swap execution in a fully trustless environment. Validators within the network operate PortalOS, creating a decentralized network of watchtowers. This architecture incorporates key components, including nodes for major supported networks, a Coordinator for efficient message routing between full nodes, and a Notary Chain to log all swap data securely.
PortalOS is the backbone of seamless multi-blockchain interoperability, enabling fast Layer 3 (L3) atomic swaps between assets held by untrusting parties across different blockchains. This technology supports the creation of custom automated market makers (AMMs) tailored to individual blockchains, utilizing smart contracts on EVM-compatible chains and secure multi-party hash time-locked contracts (HTLCs) for Bitcoin.
Designed with modularity and efficiency in mind, PortalOS is compatible with all Layer 1 and Layer 2 protocols. It integrates effortlessly with key components like the Portal Liquidity Router and Portal Coordinator, delivering scalable, interoperable, and trustless crypto transactions across diverse blockchain ecosystems.
