how can the payment information be interchanged securely and on-chain so that only makers and takers can access it?

Not hard to do Diffie-Hellman key exchange I guess. There is EIP draft on that by nitram EIP-0032: Non-interactive encryption of TX-purpose messages by nitram147 · Pull Request #64 · ergoplatform/eips · GitHub but I need to check it closely still
