On-chain vault engine · Solana

Choose your Firstance.

Same fixed rules, written into the program. Two engines — pick where you're headed.

v1

Firstance v1

One coin, one ending. Half the supply is vaulted and sold on fixed rules — then a full burn at $100M.

Enter v1 → v2

Firstance v2

A series that restarts itself. A coin that fails is liquidated and the next launches on its own — automatically.
