Class SubDemPrecisionError

Thrown by Demos.transfer (and friends) when a caller passes an OS amount with sub-DEM precision against a node that has not yet activated the osDenomination fork. The pre-fork wire shape is a JS number in DEM, which cannot represent sub-DEM precision; sending the transaction would silently truncate the user's funds. This guard fails fast at the public-API boundary before any signing happens.

Example

try {
  await demos.transfer(to, 1_234_567n) // sub-DEM precision
} catch (err) {
  if (err instanceof SubDemPrecisionError) {
    // tell the user to round, or to upgrade the node
  }
}
