Limits
- An envelope holds between $1 and $1,000.
- Only the fifteen stocks and funds listed at deployment can be sealed, each with its Uniswap pool.
- Amounts are stored raw and shown with the token's current multiplier, so splits and reinvested dividends display correctly.
- The 30 days are a constant in the contract. Nobody can change them.
