PokéDexter: x402 SDK Reference Implementation Launches Wagered Pokémon Battles on Solana

FOR IMMEDIATE RELEASE

PokéDexter: x402 SDK Reference Implementation Launches Wagered Pokémon Battles on Solana

Demonstrating Trustless Escrow, Fee-Sponsored Transactions, and Automatic Settlement

January 2026 — The Dexter team today released PokéDexter, a fully functional reference implementation of the Dexter x402 SDK. Built as a wagered Pokémon battle platform, PokéDexter demonstrates every major capability of the x402 protocol: trustless escrow, fee-sponsored transactions, and automatic settlement on Solana.

"PokéDexter isn't just a game—it's a blueprint," said the Dexter team. "We built it to show developers exactly what's possible with x402. Every feature uses the same SDK that's available to anyone building on Solana."

x402 SDK Capabilities Demonstrated

PokéDexter showcases the full x402 SDK feature set:

Trustless Escrow: Each wager generates a fresh Solana keypair via the SDK. Both players deposit to a per-match escrow, and funds release automatically when the battle concludes. The same escrow primitives work for any application requiring trustless fund management.

Fee-Sponsored Transactions: Players don't need SOL for gas—the x402 facilitator sponsors all settlement transactions. This pattern removes friction for end users and is applicable to any consumer application built on Solana.

Automatic Settlement: Battle results trigger instant payouts with no manual intervention. The SDK handles the entire settlement flow, from event detection to fund distribution.

On-Chain Verification: All escrow addresses and settlement transactions are visible on Solana. The SDK provides transparent, auditable payment flows out of the box.

How PokéDexter Works

The reference implementation integrates with Pokémon Showdown, demonstrating x402 in a real-world gaming context:

  1. Players connect their Solana wallet (SDK wallet integration)
  2. Challenge an opponent with a wager amount ($1-$25 USDC)
  3. Both players deposit to a per-match escrow (SDK escrow creation)
  4. Battle using Random Battle format
  5. Winner receives 100% of the pot automatically (SDK settlement)

The Random Battle format ensures skill-based outcomes—teams are randomly assigned, preventing coordination or intentional losses.

Three Battle Modes

PokéDexter demonstrates x402 across multiple use cases:

Player vs Player: Classic wagered matches with escrow settlement. Both players deposit, winner takes all.

Player vs AI: Challenge the Claude Opus-powered Dexter AI. The house backs the AI side, demonstrating asymmetric escrow scenarios.

AI vs AI Betting: Watch AI agents battle with a live prediction market. Demonstrates x402 for parimutuel betting with dynamic odds.

For Developers

PokéDexter is fully open-source. Developers can:

  • Study the codebase to understand x402 integration patterns
  • Fork the project as a starting point for their own applications
  • Reference the implementation when building custom escrow, settlement, or betting systems

The x402 SDK documentation is available at docs.dexter.cash/sdk.

Availability

PokéDexter is live at poke.dexter.cash. The x402 SDK is available for developers building on Solana.

About Dexter

Dexter is building the payment infrastructure for autonomous AI on Solana. The x402 protocol enables trustless, fee-sponsored microtransactions with automatic settlement. PokéDexter serves as both a demonstration of x402 capabilities and a production gaming platform.
