Chain Architecture

Solana-first design with optional EVM compatibility for Base and Polygon.

PincerPay is Solana-first. Solana's speed and cost make it the best chain for agent micropayments. EVM chains (Base, Polygon) are supported for agents and merchants that prefer them.

Solana (Primary)

  • Sub-second finality -- transactions confirm in ~400ms
  • Sub-cent fees -- a USDC transfer costs ~$0.00025
  • Kora gasless -- agents pay gas in USDC instead of SOL (live on devnet)
  • Squads SPN -- on-chain Smart Accounts with spending limits, manageable from the PincerPay dashboard (live on devnet)

Optimistic Finality

For payments under $1 USDC, PincerPay releases the resource after the transaction is broadcast to the mempool (~200ms) rather than waiting for block confirmation. This keeps latency low for micropayments while maintaining security for larger amounts.

Gas Passthrough

PincerPay never subsidizes gas. On Solana, agents pay a small SOL fee (~$0.00025) per transaction. With Kora integration, agents can pay gas in USDC instead, removing the need to hold SOL entirely.

EVM (Optional Compatibility)

Base and Polygon are supported for agents and merchants that prefer EVM:

  • Base -- Coinbase's L2, co-creators of x402
  • Polygon -- low fees, established ecosystem
  • ERC-7715 -- session keys for scoped agent permissions

Chain Identifiers

PincerPay uses short chain identifiers in SDK configuration and API responses. These map to CAIP-2 identifiers for cross-chain interoperability.

Shorthand CAIP-2 ID Network
solana solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp Solana Mainnet

Start with solana-devnet for development, then switch to solana for production.
