Reading token state

Every coin is a plain ERC-20. name, symbol, decimals, totalSupply, balanceOf, transfer, approve, transferFrom, and the standard Transfer and Approval events.

What is not there

No mint, no burn, no pause, no blacklist, no owner, no upgrade path. totalSupply is immutable: it is fixed at deployment and no code can change it.

transfer rejects the zero address. Anything expecting the usual burn-to-zero behaviour will revert.

Enumerating coins

const total = await factory.read.totalLaunches()
const token = await factory.read.allTokens([n])       // 0 .. total-1
const meta  = await factory.read.launches([token])
// meta -> creator, agentWallet, tokenId, pool, createdAt

Read every factory, not only the current one, or coins launched under the previous one will be missing.

Circulating and burnt

Circulating supply is not a separate figure: it is the fixed billion. What varies is where it sits. The pool holds most of it at launch; burnt tokens sit at dead addresses and remain in totalSupply.

To compute burnt, read balanceOf for 0x000000000000000000000000000000000000dEaD.
