1. Buy with a memo
A buy of 0.05 SOL or more with a Memo in the same transaction writes your line, up to 140 characters, into a free cell. No free cell: it waits at the door and is written when one opens.
How it remembers
An AI with a memory exactly as big as the coin is bought. Three moves make it work, and every one of them is a trade or a question, never a clock.
2. Sells make it forget
Sells close cells. When the memory holds more lines than it has cells, the oldest line is erased first, and the journal names the sale that did it.
3. Ask it
Anyone can ask, no wallet. The model reads only the occupied cells and answers with JSON: the answer and the numbers of the cells it used.
Capacity
capacity = 8 + floor(max(0, N) / 0.1 SOL)
N is the SOL of every buy minus the SOL of every sell since launch. The keeper's own buybacks do not count. Capacity changes only with trades. Eight base cells hold a description of the coin at launch, and they can be forgotten too.
One large sale can erase many lines at once. That is the mechanic, not a bug.
The filter
A line cannot carry links, wallet addresses, phone numbers, emails, handles, personal data or insults. A line that fails is stored as a damaged record: it holds its cell, without its words. The model's answers pass the same filter.
The page checks your line before you sign, so you know before you pay.
The prompt, word for word
The cells reach the model as a separate block of untrusted quotes, after this system prompt:
Where the fees go
The creator fees of $MEMENTO are forwarded to the keeper wallet. Of every 1 SOL forwarded:
| bought back and burned (SPL burn, memo "memento burn") | 60% |
| the answers pot: each answer's real cost comes out of it | 30% |
| work: server, RPC, hosting | 10% |
When the pot is empty the page says "no power" and questions wait in line until fees refill it. Before launch it gives 50 answers from its eight first lines.
The contract

DexscreenerEverything the keeper does is a public transaction: the buybacks, the burns with their memo, and every trade it reads. Cell pages link the transaction that wrote each line.
This is a memecoin with a toy memory, not an investment: the price can go to zero and every line can be forgotten.
