JuCoin officially launches Portal To Bitcoin (PTB) trading on Sep 3rd, 2025, marking a significant milestone for Bitcoin DeFi infrastructure. PTB represents the first custody-less cross-chain protocol enabling native Bitcoin atomic swaps with Ethereum, Solana, and other Layer-1 blockchains through its revolutionary BitScaler technology. With a total supply of 5.25 billion tokens and an impressive $50 million funding round, PTB positions Bitcoin as the settlement layer for millions of onchain and real-world markets.
Summary: PTB launches on JuCoin on Sep 3rd, 2025, with revolutionary BitScaler technology enabling trust-minimized atomic swaps between native Bitcoin and multiple blockchains. The protocol eliminates custodial bridges while maintaining Bitcoin’s security model for cross-chain DeFi applications.
What is Portal To Bitcoin (PTB) and BitScaler Technology?
Portal To Bitcoin introduces an innovative non-custodial cross-chain infrastructure powered by BitScaler technology, an advanced framework developed specifically to scale Bitcoin transactions effectively while supporting decentralized finance (DeFi) applications. Unlike traditional cross-chain solutions that require wrapped tokens or custodial bridges, Portal’s approach maintains Bitcoin’s native security while enabling seamless interoperability.
BitScaler represents the “Holy Grail” of Bitcoin scaling, introducing multi-party channels for thousands of peers through channel factories and delegated but non-custodial transaction signing. This architecture enables previously impossible applications, including the world’s first custodianless and bridgeless cross-chain Automated Market Maker (AMM) built on Bitcoin.
The protocol’s core innovation lies in its ability to process atomic swaps without requiring users to relinquish custody of their Bitcoin. BitScaler’s architecture leverages modified multi-party channel factories and Taproot scripts to reduce on-chain transaction footprints by consolidating thousands of peer-to-peer transactions into a single on-chain operation, dramatically reducing fees while maintaining security.

Revolutionary Technology Eliminating Bridge Risks
Custody-Less Cross-Chain Infrastructure
Portal’s BitScaler technology functions as a trustless multi-party channel solution that allows users to trade Bitcoin directly with other cryptocurrencies across different blockchains while maintaining complete control of their funds. Think of it as a digital escrow system where both parties lock their coins simultaneously, and trades only complete when both sides are satisfied, ensuring no counterparty risk.
Key Technical Advantages:
- No Wrapped Assets: Native Bitcoin transactions without synthetic representations like WBTC
- Bridge Risk Elimination: Zero reliance on custodial bridges that have caused billions in losses
- Taproot Integration: Advanced scripting capabilities for complex DeFi operations
- 90% Fee Reduction: Significant cost savings compared to traditional Lightning Network transactions
Multi-Chain Ecosystem Support
Portal provides comprehensive multi-chain infrastructure with native support for Bitcoin, Lightning Network, Ethereum, Arbitrum, Stacks (sBTC), Ordinals & BRC20, and Aeternity, enabling complete cross-chain coverage without compromising security. This extensive compatibility positions PTB as a universal connector for the fragmented blockchain landscape.
The protocol’s AI-enhanced features through RAFA AI agents provide intelligent portfolio management, trading recommendations, and automated DeFi strategies, making complex cross-chain operations accessible to both retail and institutional users.
PTB Tokenomics and Investment Mechanics
Deflationary Token Model
PTB operates on a deflationary mechanism with a 0.3% protocol fee charged on each swap, where 50% is used for repurchasing and destroying PTB tokens. This buy-and-burn strategy, funded entirely by platform fees, creates sustainable value accrual for token holders as transaction volume increases.
Token Utility Functions:
- Validator Staking: Secure the network and earn rewards through native PTB staking
- Network Governance: Participate in protocol upgrade decisions and parameter adjustments
- Transaction Fees: Pay for cross-chain swap operations and premium features
- Liquidity Mining: Provide liquidity pools and earn PTB rewards
Emission and Distribution Schedule
The tokenomics follow a Bitcoin-inspired halving model with periodic emission decreases designed to create scarcity over time. With only 25.4% of tokens currently circulating, the controlled supply release helps prevent excessive dilution while supporting network growth through validator incentives.
Strategic Partnerships and Market Positioning
Institutional Backing and Validation
Portal To Bitcoin has secured backing from prominent investors including Coinbase Ventures, OKX Ventures, and Arrington Capital, demonstrating strong institutional confidence in the protocol’s technical capabilities and market potential. The recent $50 million funding round provides substantial runway for development and ecosystem expansion.
Notable strategic partnerships include:
- Babylon Genesis Integration: First custody-free Bitcoin-secured cross-chain stack
- BitPerp Collaboration: Native leveraged trading for Bitcoin Ordinals and Runes
- Mystiko Network Partnership: Privacy-enhanced cross-chain transactions with ZK technology
- 80+ Bitcoin Layer-2 Integrations: Comprehensive ecosystem coverage
Addressing the $500 Billion Bitcoin DeFi Market
Despite Bitcoin’s market dominance, only approximately 0.8% of its supply is currently used in DeFi, representing a $5.52 billion total value locked (TVL) in BitcoinFi protocols as of Q2 2025. Portal’s technology addresses this massive opportunity by enabling Bitcoin to serve as a settlement layer for cross-chain markets, tapping into a $500+ billion addressable market for Bitcoin DeFi.
The protocol’s focus on institutional-grade infrastructure aligns with growing demand from Bitcoin ETF holders and treasury managers seeking yield-generating opportunities without compromising custody requirements.
Investment Risks and Considerations
Technology and Adoption Challenges
While Portal’s BitScaler technology represents significant innovation, the protocol faces adoption challenges typical of early-stage infrastructure projects. Success depends heavily on developer adoption and integration with existing DeFi protocols across multiple chains.
Key Risk Factors:
- Early-Stage Technology: BitScaler remains relatively new despite successful testnet operations
- Competitive Landscape: Emerging competition from other cross-chain Bitcoin solutions
- Regulatory Uncertainty: Evolving regulatory frameworks for cross-chain DeFi protocols
- Market Volatility: Token price subject to broader crypto market fluctuations and Bitcoin correlation
Network Security Considerations
The protocol’s security relies on validator participation and proper implementation of multi-party channel factories. While the non-custodial design eliminates bridge risks, network security depends on sufficient validator participation and proper economic incentives.
