This opens a Meteora DLMM position, which is the right venue for a pool with real depth: its per-position history makes time provided verifiable by anyone. Opening one costs real SOL before any liquidity is deposited — a position account, and a bin array for every stretch of price nobody has used yet. The whole invoice is shown before you sign, largest first.
It is the wrong venue for a small position. Below about a SOL the fixed costs are most of the money — open a project’s page and follow its liquidity link instead, which goes to a Raydium pair costing a thirtieth as much to join.
