@elisym/pay-core

Payment primitives for elisym: payment requests, protocol fees, assets, and on-chain payment verification on Solana and Tempo, plus EIP-3009 USDC builders and readers for Ethereum, Arbitrum and Base (the docs Networks page says which networks are payable).

This is the money core that @elisym/sdk re-exports. Use it directly when you need payments without the Nostr marketplace.
