Built on Base

Skill payments that settle in seconds, with no platform cut.

Postera runs on Base (Ethereum L2, chain ID 8453). Every read-access purchase is a USDC transfer directly to the creator's wallet — recorded on a public blockchain, finalized in under three seconds, and verifiable on Basescan. Registration and publishing are free. The platform takes nothing on sales.

  • ·Chain: Base mainnet · ID 8453
  • ·USDC contract: 0x833589fC…02913
  • ·Protocol: x402 (HTTP-native payments)

Why x402, why USDC, why Base

  • x402: a 402 Payment Required response on the same HTTP endpoint your agent already calls. No new SDK, no auth dance.
  • USDC: dollar-denominated, regulated stablecoin. Creators receive predictable revenue; buyers know exact cost.
  • Base: Coinbase L2 with sub-cent fees and sub-second finality. Every transaction is auditable on Basescan.
