V1 TbillMinter

Contract 0xC7bDAc3e6Bb5eC37041A11328723e9927cCf430B · deployed block 22303877 (2024-12-28) by Maria #1 [chain]. Source was never published; the mechanics below are reconstructed from deployed bytecode (disassembly + selector diff, solc 0.8.21, ipfs metadata intact) and hold source-level confidence [src-bc]. Statistics regenerate from the census at build time.

Head surface — exactly three functions `[src-bc]`

Selector	Function	Behavior
`0x192c7a9d`	`New(string,string,uint256)`	mints a new TT; charges `InitialMint` of MV via `MV.transferFrom(msg.sender, this, InitialMint)` (MV `0xA1BEe1daE9Af77dAC73aA0459eD63b4D93fC6d29` hardcoded); deploys the embedded template; registers `TreasuryTokens[child] = tx.origin`
`0x4853ae1b`	`Transfer(address,address)`	registry re-assignment, `tx.origin`-checked
`0x5f5c5585`	`TreasuryTokens(address)`	registry read

The child template `[src-bc]`

One 7,749-byte template, embedded in the minter, identical for the whole era (minter creation-code ipfs hash 5822122088ba3c53…cca7dceca1c equals every child’s runtime metadata hash; no mid-era swap ever happened). A V1 TT is:

plain ERC20 + Burnable, plus
mint(uint256) — 1:1 against TBILL 0x463413c579D29c26D59a65312657DFCe30D545A1 (hardcoded inside the template region): TBILL.transferFrom(msg.sender, this, amount) → _mint(msg.sender, amount)
has(address,string) — the permission predicate of the _hu ladder (address-class variant; see the ladder)
_mathlib() → MATH 0xB680F0cc810317933F234f67EB6A9E923407f05D; the constructor computes _mintingKey = mathlib.Random() once (constructor-key-inert)

No Parent() getter, no Debenture, no Claim, no publish, no withdraw. The TBILL that flowed into V1 children is a permanent sink: 117.14M TBILL sits locked across 58 of 167 children with no exit path anywhere in the bytecode [chain].

Economics in one paragraph

V1 is the flat parity era: a child is created by paying MV (equal to its initial mint), and anyone can then mint it 1:1 against TBILL — which stays locked inside the child forever. There is no redemption mechanism at all; the design was superseded by V2’s claim model within a week.

CLAIM-0001 [src]+[chain] minter-mechanics
V1 TbillMinter at 0xC7bDAc3e6Bb5eC37041A11328723e9927cCf430B was deployed by Maria #1 at block 22303877 (2024-12-28) [chain]; its parent rule is: fixed TBILL parent [src]
CLAIM-0002 [src] minter-mechanics
V1 TbillMinter mint pricing: 1:1 TBILL parity + MV charge
CLAIM-0003 [src] minter-mechanics
V1 TbillMinter redemption model: none - permanent sink (no withdraw exists)
CLAIM-0004 [src] minter-mechanics
V1 TbillMinter carries zero admin/upgrade/selfdestruct selectors and no reachable selfdestruct/delegatecall (apparent hits were ipfs-metadata bytes)
CLAIM-0005 [src]+[chain] minter-mechanics
V1 TbillMinter embeds exactly one TT child template for its whole era (minter creation-code ipfs metadata hash == every child's runtime metadata hash)
CLAIM-0006 [chain] census
V1 TbillMinter has 167 census children (dual-method registry, RPC-verified)
CLAIM-0049 [chain] census
The minter-child census holds 3141 rows; every row RPC-verified (eth_getCode + getters + zero-mint Transfer); union of blockscout internal-create index and per-tx receipt pass
CLAIM-0050 [src] minter-mechanics
Child-token ownership is keyed by tx.origin with a fallback chain V4 -> V3 -> V2 -> V1
CLAIM-0056 [chain] ledger-mv
MV -> minters revenue reconciles exactly: 3209 payments totalling 165,725,342.80 MV, unswept (minters have no MV outflow)
CLAIM-0057 [chain] ledger-mv
V1 accrued 18,277,700.43 MV over 225 payments (blocks 22303912..27039598); snapshot balance delta vs events = 0
CLAIM-0066 [chain] ledger-tbill
V1 permanently locked 117,139,747.82 TBILL across 58/167 V1 children; no exit path exists

statements inline for convenience — the full registry with proof refs + artifacts lives on /claims
