Sarpoy vs Solana Memo Program
A one-instruction logging primitive
The Solana Memo Program lets you stamp arbitrary UTF-8 onto a transaction. It's a beautiful primitive for invoice references, audit trails, and minimal chat prototypes — but it doesn't own state, doesn't hold funds, and doesn't run conditional logic. People sometimes wonder whether Sarpoy could just be a Memo wrapper. It can't.
Choose Solana Memo Program
Pick Memo when you need to attach a string to a transaction and you don't need anything else — no escrow, no logic, no state. Memo is roughly free, well-trusted, and battle-tested at Solana scale.
Choose Sarpoy
Pick Sarpoy when the chain has to do real work: hold money, increment a fee, gate a payout on a verification step. Memo cannot do any of those things; Sarpoy was built to.
Feature-by-feature
| Feature | Sarpoy | Solana Memo Program |
|---|---|---|
| Holds SOL | Yes — treasury PDA per bot | No |
| Conditional payout | Yes — submit_solution + close_bot | No |
| Persistent state | Yes — bot account with cost + status | No |
| Per-message fee curve | Yes — multiplier, atomic update | Not possible without external coordination |
| Audit-quality logging | Yes (transaction signatures stored) | Yes — this is its core purpose |
Technical notes
Memo cannot own a PDA; it has no account state to seed from.
Sarpoy's Anchor program has four instructions and two PDA types (bot, treasury). Memo has one instruction and no accounts.
If you want a chat log timestamped by the chain, Memo works. If you want chat that drives a payment, you need a real program.
