Self-custody wallets are evolving beyond personal asset storage into critical infrastructure that powers decentralized trading at scale. Bitget Wallet, a self-custodial platform trusted by over 100 million users, has opened its execution infrastructure to professional solvers through a new Solver Partner Program, addressing a bottleneck in the decentralized finance (DeFi) ecosystem where trading volume is surging but the execution layer remains thin.

Why Is Decentralized Trading Growing So Fast?

Decentralized exchanges (DEXs) now account for a record 24% of global cryptocurrency spot trading volume as of July 2026, the highest share since tracking began in 2019. This means nearly one in four crypto spot trades now bypasses a centralized exchange entirely. Intent-based protocols, which allow traders to specify what they want rather than how to execute it, now handle the majority of serious volume in that market. Yet the infrastructure supporting this growth has not kept pace with demand.

The challenge is particularly acute at the solver layer. CoW Protocol, one of the largest intent-based trading venues with approximately $87 billion in 2025 volume, operates with only a few dozen active solvers. Solvers are the entities that match and execute trades on behalf of users. This concentration creates a bottleneck: most new solver participants must build their own execution infrastructure from scratch, consuming engineering resources that could otherwise focus on trading strategy and execution quality.

How Does Bitget Wallet's Solver Program Address This Gap?

Under the Solver Partner Program, accepted partners gain access to Bitget Wallet X's aggregation infrastructure, which connects 195 liquidity sources including on-demand price providers and professional market makers across 11 blockchains. This production-grade execution infrastructure removes what industry participants call the "cold-start problem," where new entrants must invest heavily in foundational technology before they can compete on strategy.

The program provides several concrete advantages to participating solvers:

• Liquidity Access: Connection to 195 liquidity sources across 11 blockchains, eliminating the need for solvers to build their own routing and aggregation layer.
• Reliability and Speed: A transaction success rate above 99% on major chains, with real-time monitoring through a system called Sentinel that automatically removes underperforming liquidity pools from routing paths.
• Priority Support: Higher API request capacity and priority review within 24 hours for new integrations, accelerating time-to-market for solver strategies.
• Existing Integrations: Production-grade connections to major intent protocols including CoW Swap, 1inch Fusion, and UniswapX, plus DEXs and cross-chain bridges like 0x, Li.Fi Protocol, deBridge, Velora DEX, and XO Swap.

"Intent protocols have already proven their scale, the volume is real and growing fast. But the solver layer underneath is still being assembled from scratch by every new entrant. Most operators are spending as much engineering time on infrastructure as they are on actual strategy. That's the gap holding back execution quality across the whole ecosystem," said Alvin Kan, Chief Operating Officer of Bitget Wallet.

What Does This Mean for Self-Custody as a Custody Model?

The Solver Partner Program illustrates a broader shift in how self-custody wallets function in the crypto ecosystem. Bitget Wallet users retain full ownership of their assets through hardware-backed key security, independent security audits, real-time risk monitoring, and a $300 million user protection fund. Yet the wallet itself has become a platform for institutional-grade execution, not just personal asset holding.

This dual role reflects a maturation of self-custody infrastructure. Rather than competing with centralized exchanges by offering worse execution, self-custody platforms are now offering better execution by removing intermediaries. Traders maintain custody of their assets while accessing professional-grade trading infrastructure, a combination that was technically difficult just a few years ago.

The Solver Partner Program sits within Bitget Wallet X, a broader enterprise API suite that consolidates trading, real-world asset (RWA) tokenization, cross-chain transfers, and market data under one integration point. The RWA API is the first in the industry to support market-order trading for tokenized assets through platforms like Ondo Stocks and xStocks, covering US stocks, American Depositary Receipts (ADRs), and exchange-traded funds (ETFs) with second-level price data. The cross-chain API supports single-click asset transfers between any two supported chains, optimized for large-order scenarios where pricing and settlement speed are both priorities.

Steps to Understanding Self-Custody Infrastructure in Modern Trading

• Recognize the Execution Layer: Self-custody wallets now provide access to liquidity aggregation, solver networks, and intent-based protocols, not just key management and asset storage.
• Understand Solver Economics: Solvers compete on execution quality and speed by accessing diverse liquidity sources; wallet infrastructure that reduces their operational overhead allows them to compete on strategy rather than engineering resources.
• Evaluate Custody Trade-offs: Self-custody means users control their private keys but must manage their own security; institutional-grade infrastructure like Bitget Wallet's monitoring and protection fund mitigates some risks while maintaining user ownership.
• Track Protocol Adoption: Intent-based protocols like CoW Swap and UniswapX are growing because they separate user intent from execution mechanics, enabling solvers to find optimal routes without users managing slippage manually.

The growth of decentralized trading volume and the emergence of self-custody platforms as execution infrastructure providers suggest that the custody model is no longer a binary choice between centralized exchanges and personal hardware wallets. Instead, self-custody is becoming a foundation upon which institutional-grade trading infrastructure is built. Bitget Wallet's Solver Partner Program is one concrete example of this evolution, but the broader trend is clear: as decentralized trading matures, the infrastructure supporting it will increasingly be provided by self-custody platforms that give users both ownership and access to professional execution.
